(6) AP-5181 LEDs The AP-5181 access point has four LEDs matching the functionality of the AP-5131 model access point. The five LEDs on the top housing of the AP-5181 are clearly visible in table-top, wall and below ceiling installations. The five top housing LEDs have the following display and functionality:
Power Status - Solid white indicates the AP-5131 is adequately powered. Error Conditions - Solid red indicates the AP is experiencing a problem requiring attention. Ethernet Activity - Flashing white indicates data transfers and Ethernet activity. 802.11a Activity - Flickering amber indicates beacons and data transfers over the radio.. 802.11b/g Activity - Flickering green indicates beacons and data transfers over the radio. Symbol Power Injector The access point can receive power either directly form a Symbol 48V AC-DC power supply or via an Ethernet cable connected to the LAN port (using the 802.3af standard). When users purchase a Symbol WLAN solution, they often need to place access points in obscure locations. In the past, a dedicated power source was required for each access point in addition to the Ethernet infrastructure. This often required an electrical contractor to install power drops at each access point location. An approved power injector solution merges power and Ethernet into one cable, reducing the burden of installation and allows optimal access point placement in respect to the intended radio coverage area.

Product Description The AP-5181 has a separate LAN and WAN port for connecting to the network and receiving 802.3af power (over the AP-5181s LAN port only). The AP-5181 has four antenna connectors
(on top) supporting 802.11a and 802.11g antenna options. However, the AP-5181 antenna suite is designed for outdoor deployments, so the existing AP-5131 antenna suite should not be used with an AP-5181. The AP-5181s mode of operation is identical to the AP-5131s. Mounting the AP-5181 The AP-5181 can be mounted to a pole (1.5 - 18 inches in diameter) or to a wall. The AP-5181 Wall Mounting Kit (Part No. KT-5181-WP-01R) is not included with AP-5181 and must be ordered separately. The mounting bracket has four parts. One rectangular plate used for pole and wall mounting, one square plate that attaches directly to the AP-5181 and two plates forming an adjustable V-shaped clamp for pole mounting.

Symbol Power Injector Solutions An AP-5181 access point receives power via an Ethernet cable connected to the AP-5181s LAN port (using the 802.3af standard). When users purchase a Symbol WLAN solution, they often need to place access points in obscure locations. In the past, a dedicated power source was required for each access point in addition to the Ethernet infrastructure. This often required an electrical contractor to install power drops at each access point location. An approved 802.3af solution merges power and Ethernet into one cable, reducing the burden of installation and allows optimal access point placement in respect to the intended radio coverage area. An AP-5181 model access point can use one of two approved Symbol single-port solutions. Both the Symbol Power Tap (Part No. AP-PSBIAS-5181-01R) and Symbol Power Injector (Part No. AP-PSBIAS-1P2-AFR) are integrated AC-DC converters and 802.3af Power Injectors using 110-220V AC power to combine low-voltage DC with Ethernet data in a single cable connecting to the AP-5181s LAN port. The Symbol Power Tap is a ruggedized solution (designed for outdoor deployments), and may be better suited for an AP-5181 installation prone to wind and rain. A Power Injector (Part No. AP-PSBIAS-1P2-AFR) can only be used for indoor installations. A Power Injector or Power Tap receives power and is ready for AP-5181 connection and operation as soon as AC power is applied. There in no On/Off switch. Caution - The AP-5181 supports any standards-based 802.3af compliant power source
(including non-Symbol power sources). However, using the wrong solution (including a non-
compliant POE system or a solution not rated for outdoor use) could severely damage the AP-5181 and void the product warranty. Caution - For Power Tap installations, a electrician is required to open the unit, feed the power cable through the Line AC connector, secure the power cable to the units three screw termination block and tighten the units Line AC clamp (by hand) to secure the power cable. Only a certified electrician should conduct the installation. Additionally, an electrician must attach a ground cable between the EARTH GROUND connector (on the back of the unit) to a suitable earth ground connection as defined by your local electrical code.

Introduction This AP-51xx Product Reference Guide contains setup and advanced configuration instructions for both the AP-5131 and AP-5181 model Symbol access points. Both the AP-5131 and AP-5181 model access points share the same Web UI interface, thus there is no difference in how the devices are configured using the instructions within this guide. However, there are marked differences in how the devices are physically installed, as the AP-5181 is constructed to support outdoor installations, while the AP-5131 model is constructed primarily for indoor deployments. The access point (AP) provides a bridge between Ethernet wired LANs or WANs and wireless networks. It provides connectivity between Ethernet wired networks and radio-equipped mobile units
(MUs). MUs include the full line of Symbol terminals, bar-code scanners, adapters (PC cards, Compact Flash cards and PCI adapters) and other devices. The access point provides a maximum 54Mbps data transfer rate via each radio. It monitors Ethernet traffic and forwards appropriate Ethernet messages to MUs over the network. It also monitors MU radio traffic and forwards MU packets to the Ethernet LAN. If you are new to using an access point for managing your network, refer to Theory of Operations on page 1-19 for an overview on wireless networking fundamentals. 1-2 AP-51xx Access Point Product Reference Guide 1.1 New Features With this most recent 1.1 release of the access point firmware, the following new features have been introduced to the existing feature set:
Mesh Networking
Additional LAN Subnet
On-board Radius Server Authentication
Hotspot Support
Routing Information Protocol (RIP)
Manual Date and Time Settings 1.1.1 Mesh Networking Utilize the new mesh networking functionality to allow the access point to function as a bridge to connect two Ethernet networks or as a repeater to extend your networks coverage area without additional cabling. Mesh networking is configurable in two modes. It can be set in a wireless client bridge mode and/or a wireless base bridge mode (which accepts connections from client bridges). These two modes are not mutually exclusive. In client bridge mode, the access point scans to find other access points using the selected WLANs ESSID. The access point must go through the association and authentication process to establish a wireless connection. The mesh networking association process is identical to the access points MU association process. Once the association/authentication process is complete, the wireless client adds the connection as a port on its bridge module. This causes the access point (in client bridge mode) to begin forwarding configuration packets to the base bridge. An access point in base bridge mode allows the access point radio to accept client bridge connections. The two bridges communicate using the Spanning Tree Protocol (STP). The spanning tree determines the path to the root and detects if the current connection is part of a network loop with another connection. Once the spanning tree converges, both access points begin learning which destinations reside on which side of the network. This allows them to forward traffic intelligently. After the access point (in client bridge mode) establishes at least one wireless connection, it will begin beaconing and accepting wireless connections (if configured to support mobile users). If the access point is configured as both a client bridge and a base bridge, it begins accepting client bridge connections. In this way, the mesh network builds itself over time and distance. Introduction 1-3 Once the access point (in client bridge mode) establishes at least one wireless connection, it establishes other wireless connections in the background as they become available. In this way, the access point is able to establish simultaneous redundant links. An access point (in client bridge mode) can establish up to 3 simultaneous wireless connections with other AP-5131s or AP-5181s. A client bridge always initiates the connections and the base bridge is always the acceptor of the mesh network data proliferating the network. Since each access point can establish up to 3 simultaneous wireless connections, some of these connections may be redundant. In that case, the STP algorithm establishes which links are the redundant links and disables the links from forwarding. For an overview on mesh networking as well as details on configuring the access points mesh networking functionality, see Configuring Mesh Networking on page 9-1. 1.1.2 Additional LAN Subnet In a typical retail or small office environment (wherein a wireless network is available along with a production WLAN) it is frequently necessary to segment a LAN into two subnets. Consequently, a second LAN is necessary to segregate wireless traffic. The access point now has a second LAN subnet enabling administrators to segment the access points LAN connection into two separate networks. The main access point LAN screen now allows the user to select either LAN1 or LAN2 as the active LAN over the access points Ethernet port. Both LANs can still be active at any given time, but only one can transmit over the access point physical LAN connection. Each LAN has a separate configuration screen (called LAN 1 and LAN 2 by default) accessible under the main LAN screen. The user can rename each LAN as necessary. Additionally, each LAN can have its own Ethernet Type Filter configuration, and subnet access (HTTP, SSH, SNMP and telnet) configuration. For detailed information on configuring the access point for additional LAN subnet support, see Configuring the LAN Interface on page 5-1. 1-4 AP-51xx Access Point Product Reference Guide 1.1.3 On-board Radius Server Authentication The access point now has the ability to work as a Radius Server to provide user database information and user authentication. Several new screens have been added to the access points menu tree to configure Radius server authentication and configure the local user database and access policies. A new Radius Server screen allows an administrator to define the data source, authentication type and associate digital certificates with the authentication scheme. The LDAP screen allows the administrator to configure an external LDAP Server for use with the access point. A new Access Policy screen enables the administrator to set WLAN access based on user groups defined within the User Database screen. Each user is authorized based on the access policies applicable to that user. Access policies allow an administrator to control access to a user groups based on the WLAN configurations. For detailed information on configuring the access point for AAA Radius Server support, see Configuring User Authentication on page 6-61. 1.1.4 Hotspot Support The access point now allows hotspot operators to provide user authentication and accounting without a special client application. The access point uses a traditional Internet browser as a secure authentication device. Rather than rely on built-in 802.11security features to control access point association privileges, you can configure a WLAN with no WEP (an open network). The access point issues an IP address to the user using a DHCP server, authenticates the user and grants the user to access the Internet. If a tourist visits a public hotspot and wants to browse a Web page, they boot their laptop and associate with a local Wi-Fi network by entering a valid SSID. They start a browser, and the hotspots access controller forces the un-authenticated user to a Welcome page (from the hotspot operator) that allows the user to login with a username and password. In order to send a redirected page (a login page), a TCP termination exists locally on the access point. Once the login page displays, the user enters their credentials. The access point connects to the Radius server and determines the identity of the connected wireless user. Thus, allowing the user to access the Internet once successfully authenticated. For detailed information on configuring the access point for Hotspot support, see Configuring WLAN Hotspot Support on page 5-39. Introduction 1-5 1.1.5 Routing Information Protocol (RIP) With the release of the 1.1 version access point, Routing Information Protocol (RIP) functionality has been added to the existing Router screen. RIP is an interior gateway protocol that specifies how routers exchange routing-table information. The parent Router screen also allows the administrator to select the type of RIP and the type of RIP authentication used. For detailed information on configuring RIP functionality as part of the access points Router functionality, see Setting the RIP Configuration on page 5-58. 1.1.6 Manual Date and Time Settings As an alternative to defining a NTP server to provide access point system time, the access point can now have its date and time set manually. A new Manual Date/Time Setting screen can be used to set the access point time using a Year-Month-Day HH:MM:SS format. For detailed information on manually setting the access points system time, see Configuring Network Time Protocol (NTP) on page 4-31. 1-6 AP-51xx Access Point Product Reference Guide 1.2 Feature Overview The Symbol access point has the following existing features carried forward from its initial 1.0 release:

If the access point is manufactured as a single radio access point, the access point enables you to configure the single radio for either 802.11a or 802.11b/g. If the access point is manufactured as a dual-radio access point, the access point enables you to configure one radio for 802.11a, and the other 802.11b/g. For detailed information on configuring your access point, see Setting the WLANs Radio Configuration on page 5-44. 1.2.2 Separate LAN and WAN Ports The access point has one LAN port and one WAN port, each with their own MAC address. The access point must manage all data traffic over the LAN connection carefully as either a DHCP client, BOOTP client, DHCP server or using a static IP address. The access point can only use a Power-over-Ethernet device when connected to the LAN port. For detailed information on configuring the access point LAN port, see Configuring the LAN Interface on page 5-1. A Wide Area Network (WAN) is a widely dispersed telecommunications network. In a corporate environment, the WAN port might connect to a larger corporate network. For a small business, the WAN port might connect to a DSL or cable modem to access the Internet. Regardless, network address information must be configured for the access points intended mode of operation. For detailed information on configuring the access points WAN port, see Configuring WAN Settings on page 5-14. The LAN and WAN port MAC addresses can be located within the LAN and WAN Stats screens. For detailed information on locating the access point MAC addresses, see Viewing WAN Statistics on page 7-2 and Viewing LAN Statistics on page 7-6. 1.2.3 Multiple Mounting Options The access point rests on a flat surface, attaches to a wall, mounts under a ceiling or above a ceiling
(attic). Choose a mounting option based on the physical environment of the coverage area. Do not mount the access point in a location that has not been approved in an access point radio coverage site survey. 1-8 AP-51xx Access Point Product Reference Guide For detailed information on the mounting options available for the access point, see Mounting the AP-5131 on page 2-12. 1.2.4 Antenna Support for 2.4 GHz and 5.2 GHz Radios The access point supports several 802.11a and 802.11b/g radio antennas. Select the antenna best suited to the radio transmission requirements of your coverage area. For an overview of the Radio 1 (2.4 GHz) and Radio 2 (5.2 GHz) antennas supported on the access points Reverse SMA (RSMA) connectors, see Antenna Specifications on page A-5. 1.2.5 Sixteen Configurable WLANs A Wireless Local Area Network (WLAN) is a data-communications system that flexibly extends the functionalities of a wired LAN. A WLAN does not require lining up devices for line-of-sight transmission, and are thus, desirable for wireless networking. Roaming users can be handed off from one access point to another like a cellular phone system. WLANs can therefore be configured around the needs of specific groups of users, even when they are not in physical proximity. Sixteen WLANs are configurable on each access point. To enable and configure WLANs on an access point radio, see Enabling Wireless LANs (WLANs) on page 5-22. 1.2.6 Support for 4 BSSIDs per Radio The access point supports four BSSIDs per radio. Each BSSID has a corresponding MAC address. The first MAC address corresponds to BSSID #1. The MAC addresses for the other three BSSIDs (BSSIDs
#2, #3, #4) are derived by adding 1, 2, 3, respectively, to the radio MAC address. If the radio MAC address displayed on the Radio Settings screen is 00:A0:F8:72:20:DC, then the BSSIDs for that radio will have the following MAC addresses:
BSSID MAC Address Hexadecimal Addition BSSID #1 BSSID #2 BSSID #3 BSSID #4 00:A0:F8:72:20:DC 00:A0:F8:72:20:DD 00:A0:F8:72:20:DE 00:A0:F8:72:20:DF Same as Radio MAC address Radio MAC address +1 Radio MAC address +2 Radio MAC address +3 For detailed information on strategically mapping BSSIDs to WLANs, see Configuring the 802.11a or 802.11b/g Radio on page 5-47. Introduction 1-9 1-10 AP-51xx Access Point Product Reference Guide 1.2.7 Quality of Service (QoS) Support The access point QoS implementation provides applications running on different wireless devices a variety of priority levels to transmit data to and from the access point. Equal data transmission priority is fine for data traffic from applications such as Web browsers, file transfers or email, but is inadequate for multimedia applications. Voice over Internet Protocol (VoIP), video streaming and interactive gaming are highly sensitive to latency increases and throughput reductions. These forms of higher priority data traffic can significantly benefit from the access point QoS implementation.The WiFi Multimedia QOS Extensions
(WMM) implementation used by the access point shortens the time between transmitting higher priority data traffic and is thus desirable for multimedia applications. In addition, U-APSD (WMM Power Save) is also supported. WMM defines four access categoriesvoice, video, best effort and backgroundto prioritize traffic for providing enhanced multimedia support. For detailed information on configuring QoS support for the access point, see Setting the WLAN Quality of Service (QoS) Policy on page 5-33. 1.2.8 Industry Leading Data Security The access point supports numerous encryption and authentication techniques to protect the data transmitting on the WLAN. The following authentication techniques are supported on the access point:
Kerberos Authentication
EAP Authentication The following encryption techniques are supported on the access point:
WEP Encryption
KeyGuard Encryption
Wi-Fi Protected Access (WPA) Using TKIP Encryption
WPA2-CCMP (802.11i) Encryption In addition, the access point supports the following additional security features:
Firewall Security
VPN Tunnels Introduction 1-11
Content Filtering For an overview on the encryption and authentication schemes available on the access point, refer to Configuring Access Point Security on page 6-1. 1.2.8.1 Kerberos Authentication Authentication is a means of verifying information that is transmitted from a secure source. If information is authentic, you know who created it and you know that it has not been altered in any way since it was originated. Authentication entails a network administrator employing a software supplicant on their computer or wireless device. Authentication is critical for the security of any wireless LAN device. Traditional authentication methods are not suitable for use in wireless networks where an unauthorized user can monitor network traffic and intercept passwords. The use of strong authentication methods that do not disclose passwords is necessary. Symbol uses the Kerberos authentication service protocol (specified in RFC 1510), to authenticate users/clients in a wireless network environment and to securely distribute the encryption keys used for both encrypting and decrypting. A basic understanding of RFC 1510 Kerberos Network Authentication Service (V5) is helpful in understanding how Kerberos functions. By default, WLAN devices operate in an open system network where any wireless device can associate with an AP without authorization. Kerberos requires device authentication before access to the wired network is permitted. For detailed information on Kerbeors configurations, see Configuring Kerberos Authentication on page 6-9. 1.2.8.2 EAP Authentication The Extensible Authentication Protocol (EAP) feature provides access points and their associated MUs an additional measure of security for data transmitted over the wireless network. Using EAP, authentication between devices is achieved through the exchange and verification of certificates. EAP is a mutual authentication method whereby both the MU and AP are required to prove their identities. Like Kerberos, the user loses device authentication if the server cannot provide proof of device identification Using EAP, a user requests connection to a WLAN through the access point. The access point then requests the identity of the user and transmits that identity to an authentication server. The server prompts the AP for proof of identity (supplied to the access point by the user) and then transmits the user data back to the server to complete the authentication. 1-12 AP-51xx Access Point Product Reference Guide An MU is not able to access the network if not authenticated. When configured for EAP support, the access point displays the MU as an EAP station. EAP is only supported on mobile devices running Windows XP, Windows 2000 (using Service Pack #4) and Windows Mobile 2003. Refer to the system administrator for information on configuring a Radius Server for EAP (802.1x) support. For detailed information on EAP configurations, see Configuring 802.1x EAP Authentication on page 6-11. 1.2.8.3 WEP Encryption All WLAN devices face possible information theft. Theft occurs when an unauthorized user eavesdrops to obtain information illegally. The absence of a physical connection makes wireless links particularly vulnerable to this form of theft. Most forms of WLAN security rely on encryption to various extents. Encryption entails scrambling and coding information, typically with mathematical formulas called algorithms, before the information is transmitted. An algorithm is a set of instructions or formula for scrambling the data. A key is the specific code used by the algorithm to encrypt or decrypt the data. Decryption is the decoding and unscrambling of received encrypted data. The same device, host computer or front-end processor, usually performs both encryption and decryption. The data transmit or receive direction determines whether the encryption or decryption function is performed. The device takes plain text, encrypts or scrambles the text typically by mathematically combining the key with the plain text as instructed by the algorithm, then transmits the data over the network. At the receiving end, another device takes the encrypted text and decrypts, or unscrambles, the text revealing the original message. An unauthorized user can know the algorithm, but cannot interpret the encrypted data without the appropriate key. Only the sender and receiver of the transmitted data know the key. Wired Equivalent Privacy (WEP) is an encryption security protocol specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11b and supported by the access point AP. WEP encryption is designed to provide a WLAN with a level of security and privacy comparable to that of a wired LAN. The level of protection provided by WEP encryption is determined by the encryption key length and algorithm. An encryption key is a string of case sensitive characters used to encrypt and decrypt data packets transmitted between a mobile unit (MU) and the access point. An access point and associated wireless clients must use the same encryption key (typically 1 through 4) to interoperate. For detailed information on WEP configurations, see Configuring WEP Encryption on page 6-16. Introduction 1-13 1.2.8.4 KeyGuard Encryption Use KeyGuard to shield the master encryption keys from being discovered through hacking. KeyGuard negotiation takes place between the access point and MU upon association. The access point can use KeyGuard with Symbol MUs. KeyGuard is only supported on Symbol MUs making it a Symbol proprietary security mechanism. For detailed information on KeyGuard configurations, see Configuring KeyGuard Encryption on page 6-18. 1.2.8.5 Wi-Fi Protected Access (WPA) Using TKIP Encryption Wi-Fi Protected Access (WPA) is a security standard for systems operating with a Wi-Fi wireless connection. WEPs lack of user authentication mechanisms is addressed by WPA. Compared to WEP, WPA provides superior data encryption and user authentication. WPA addresses the weaknesses of WEP by including:
a per-packet key mixing function
a message integrity check
an extended initialization vector with sequencing rules
a re-keying mechanism WPA uses an encryption method called Temporal Key Integrity Protocol (TKIP). WPA employs 802.1X and Extensible Authentication Protocol (EAP). For detailed information on WPA using TKIP configurations, see Configuring WPA Using TKIP on page 6-20. 1.2.8.6 WPA2-CCMP (802.11i) Encryption WPA2 is a newer 802.11i standard that provides even stronger wireless security than Wi-Fi Protected Access (WPA) and WEP. Counter-mode/CBC-MAC Protocol (CCMP) is the security standard used by the Advanced Encryption Standard (AES). AES serves the same function TKIP does for WPA-TKIP. CCMP computes a Message Integrity Check (MIC) using the proven Cipher Block Message Authentication Code (CBC-MAC) technique. Changing just one bit in a message produces a totally different result. WPA2-CCMP is based on the concept of a Robust Security Network (RSN), which defines a hierarchy of keys with a limited lifetime (similar to TKIP). Like TKIP, the keys the administrator provides are used to derive other keys. Messages are encrypted using a 128-bit secret key and a 128-bit block of data. the end result is an encryption scheme as secure as any the access point provides. 1-14 AP-51xx Access Point Product Reference Guide For detailed information on WPA2-CCMP configurations, see Configuring WPA2-CCMP (802.11i) on page 6-22. 1.2.8.7 Firewall Security A firewall keeps personal data in and hackers out. The access point firewall prevents suspicious Internet traffic from proliferating the access point managed network. The access point performs network address translation (NAT) on packets passing to and from the WAN port. This combination provides enhanced security by monitoring communication with the wired network. For detailed information on configuring the access point firewall, see Configuring Firewall Settings on page 6-25. 1.2.8.8 VPN Tunnels Virtual Private Networks (VPNs) are IP-based networks using encryption and tunneling providing users remote access to a secure LAN. In essence, the trust relationship is extended from one LAN across the public network to another LAN, without sacrificing security. A VPN behaves like a private network; however, because the data travels through the public network, it needs several layers of security. The access point can function as a robust VPN gateway. For detailed information on configuring VPN security support, see Configuring VPN Tunnels on page 6-33. 1.2.8.9 Content Filtering Content filtering allows system administrators to block specific commands and URL extensions from going out through the access point WAN port only. Therefore, content filtering affords system administrators selective control on the content proliferating the network and is a powerful screening tool. Content filtering allows the blocking of up to 10 files or URL extensions and allows blocking of specific outbound HTTP, SMTP, and FTP requests. For detailed information on configuring content filtering support, see Configuring Content Filtering Settings on page 6-49. 1.2.9 VLAN Support A Virtual Local Area Network (VLAN) is a means to electronically separate data on the same access point from a single broadcast domain into separate broadcast domains. By using a VLAN, you can group by logical function instead of physical location. There are 16 VLANs supported on the access point. An administrator can map up to 16 WLANs to 16 VLANs and enable or disable dynamic VLAN Introduction 1-15 assignment. In addition to these 16 VLANs, the access point supports dynamic, user-based, VLANs when using EAP authentication. VLANs enable organizations to share network resources in various network segments within large areas (airports, shopping malls, etc.). A VLAN is a group of clients with a common set of requirements independent of their physical location. VLANs have the same attributes as physical LANs, but they enable administrators to group clients even when they are not members of the same network segment. For detailed information on configuring VLAN support, see Configuring VLAN Support on page 5-4. 1.2.10 Multiple Management Accessibility Options The access point can be accessed and configured using one of the following methods:
Java-Based Web UI
Human readable config file (imported via FTP or TFTP)
MIB (Management Information Base)
Command Line Interface (CLI) accessed via RS-232 or Telnet. Use the access point DB-9 serial port for direct access to the command-line interface from a PC. Use Symbol's Null-
Modem cable (Part No. 25-632878-0) for the best fitting connection. 1.2.11 Updatable Firmware Symbol periodically releases updated versions of the access point device firmware to the Symbol Web site. If the access point firmware version displayed on the System Settings page (see Configuring System Settings on page 4-2) is older than the version on the Web site, Symbol recommends updating the access point to the latest firmware version for full feature functionality. For detailed information on updating the access point firmware using FTP or TFTP, see Updating Device Firmware on page 4-40. 1.2.12 Programmable SNMP v1/v2/v3 Trap Support Simple Network Management Protocol (SNMP) facilitates the exchange of management information between network devices. SNMP uses Management Information Bases (MIBs) to manage the device configuration and monitor Internet devices in remote locations. MIB information accessed via SNMP is defined by a set of managed objects called object identifiers (OIDs). An object identifier (OID) is used to uniquely identify each object variable of a MIB. 1-16 AP-51xx Access Point Product Reference Guide SNMP allows a network administrator to configure the access point, manage network performance, find and solve network problems, and plan for network growth. The access point supports SNMP management functions for gathering information from its network components. The access point downloads site contains the following 2 MIB files:
Symbol-CC-WS2000-MIB-2.0 (standard Symbol MIB file)
Symbol-AP-5131-MIB (AP-5131 and AP-5181 specific MIB file) The access point SNMP agent functions as a command responder and is a multilingual agent responding to SNMPv1, v2c and v3 managers (command generators). The factory default configuration maintains SNMPv1/2c support of the community names, hence providing backward compatibility. For detailed information on configuring SNMP traps, see Configuring SNMP Settings on page 4-17. 1.2.13 Power-over-Ethernet Support When users purchase a Symbol WLAN solution, they often need to place access points in obscure locations. In the past, a dedicated power source was required for each access point in addition to the Ethernet infrastructure. This often required an electrical contractor to install power drops at each access point location. An approved power injector solution merges power and Ethernet into one cable, reducing the burden of installation and allows optimal access point placement in respect to the intended radio coverage area. An AP-5131 or AP-5181 can only use a Power-over-Ethernet device when connected to the LAN port. The Symbol Power Injector (Part No. AP-PSBIAS-T-1P-AF) is a single-port, 802.3af compliant Power over Ethernet hub combining low-voltage DC with Ethernet data in a single cable connecting to the access point. The Power Injectors single DC and Ethernet data cable creates a modified Ethernet cabling environment on the access points LAN port eliminating the need for separate Ethernet and power cables. For detailed information on using the Symbol Power Injector, see Symbol Power Injector System on page 2-9. 1.2.14 MU-MU Transmission Disallow The access points MU-MU Disallow feature prohibits MUs from communicating with each other even if they are on different WLANs, assuming one of the WLANs is configured to disallow MU-MU Introduction 1-17 communication. Therefore, if an MUs WLAN is configured for MU-MU disallow, it will not be able to communicate with any other MUs connected to this access point. For detailed information on configuring an access point WLAN to disallow MU to MU communications, see Creating/Editing Individual WLANs on page 5-24. 1.2.15 Voice Prioritization Each access point WLAN has the capability of having its QoS policy configured to prioritize the network traffic requirements for associated MUs. A WLAN QoS page is available for each enabled WLAN on either the access point 802.11a or 802.11b/g radio. Use the QoS page to enable voice prioritization for devices to receive the transmission priority they may not normally receive over other data traffic. Voice prioritization allows the access point to assign priority to voice traffic over data traffic, and (if necessary) assign legacy voice supported devices (non WMM supported voice devices) additional priority. For detailed information on configuring voice prioritization over other voice enabled devices, see Setting the WLAN Quality of Service (QoS) Policy on page 5-33. 1.2.16 Support for CAM and PSP MUs The access point supports both CAM and PSP powered MUs. CAM (Continuously Aware Mode) MUs leave their radios on continuously to hear every beacon and message transmitted. These systems operate without any adjustments by the access point. A beacon is a uniframe system packet broadcast by the AP to keep the network synchronized. A beacon includes the ESSID, access point MAC address, Broadcast destination addresses, a time stamp, a DTIM (Delivery Traffic Indication Message) and the TIM (Traffic Indication Map). PSP (Power Save Polling) MUs power off their radios for short periods. When a Symbol MU in PSP mode associates with an access point, it notifies the access point of its activity status. The access point responds by buffering packets received for the MU. PSP mode is used to extend an MUs battery life by enabling the MU to sleep during periods of inactivity. 1.2.17 Statistical Displays The access point can display robust transmit and receive statistics for the WAN and LAN ports. WLAN stats can be displayed collectively and individually for enabled WLANs. Transmit and receive statistics are available for the access points 802.11a and 802.11b/g radios. An advanced radio statistics page is also available to display retry histograms for specific data packet retry information. 1-18 AP-51xx Access Point Product Reference Guide Associated MU stats can be displayed collectively and individually for specific MUs. An echo (ping) test is also available to ping specific MUs to assess association strength. Finally, the access point can detect and display the properties of other APs detected within the access points radio coverage area. The type of AP detected can be displayed as well as the properties of individual APs. For detailed information on available access point statistical displays and the values they represent, see Monitoring Statistics on page 7-1. 1.2.18 Transmit Power Control The access point has a configurable power level for each radio. This enables the network administrator to define the antennas transmission power level in respect to the access points placement or network requirements as defined in the access point site survey. For detailed information on setting the radio transmit power level, see Configuring the 802.11a or 802.11b/g Radio on page 5-47. 1.2.19 Advanced Event Logging Capability The access point provides the capability for periodically logging system events. Logging events is useful in assessing the throughput and performance of the access point or troubleshooting problems on the access point managed Local Area Network (LAN). For detailed information on access point events, see Logging Configuration on page 4-34. 1.2.20 Configuration File Import/Export Functionality Configuration settings for an access point can be downloaded from the current configuration of another access point. This affords the administrator the opportunity to save the current configuration before making significant changes or restoring the default configuration. For detailed information on importing or exporting configuration files, see Importing/Exporting Configurations on page 4-36. 1.2.21 Default Configuration Restoration The access point has the ability to restore its default configuration or a partial default configuration with the exception of current WAN and SNMP settings. Restoring the default configuration is a good way to create new WLANs if the MUs the access point supports have been moved to different radio coverage areas. Introduction 1-19 For detailed information on restoring a default or partial default configuration, see Configuring System Settings on page 4-2. 1.2.22 DHCP Support The access point can use Dynamic Host Configuration Protocol (DHCP) to obtain a leased IP address and configuration information from a remote server. DHCP is based on the BOOTP protocol and can coexist or interoperate with BOOTP. Configure the access point to send out a DHCP request searching for a DHCP/BOOTP server to acquire HTML, firmware or network configuration files when the access point boots. Because BOOTP and DHCP interoperate, whichever responds first becomes the server that allocates information. The access point can be set to only accept replies from DHCP or BOOTP servers or both (this is the default setting). Disabling DHCP disables BOOTP and DHCP and requires network settings to be set manually. If running both DHCP and BOOTP, do not select BOOTP Only. BOOTP should only be used when the server is running BOOTP exclusively. The DHCP client automatically sends a DHCP request at an interval specified by the DHCP server to renew the IP address lease as long as the access point is running (this parameter is programmed at the DHCP server). For example: Windows 2000 servers typically are set for 3 days. 1.2.23 Multi-Function LEDs The access point houses seven LED indicators. Four LEDs exist on the top of the access point and are visible from wall, ceiling and table-top orientations. Three of these four LEDs are single color activity LEDs, and one is a multi-function red and white status LED. Two LEDs exist on the rear of the access point and are viewable using a single (customer installed) extended light pipe, adjusted as required to suit above the ceiling installations. For detailed information of the access point LEDs and their functionality, see AP-5131 LED Indicators on page 2-21. 1.3 Theory of Operations To understand access point management and performance alternatives, users need familiarity with access point functionality and configuration options. The access point includes features for different interface connections and network management. 1-20 AP-51xx Access Point Product Reference Guide The access point uses electromagnetic waves to transmit and receive electric signals without wires. Users communicate with the network by establishing radio links between mobile units (MUs) and access points. The access point uses DSSS (direct sequence spread spectrum) to transmit digital data from one device to another. A radio signal begins with a carrier signal that provides the base or center frequency. The digital data signal is encoded onto the carriers using a DSSS chipping algorithm. The access point radio signal propagates into the air as electromagnetic waves. A receiving antenna (on the MU) in the path of the waves absorbs the waves as electrical signals. The receiving MU interprets
(demodulates) the signal by reapplying the direct sequence chipping code. This demodulation results in the original digital data. The access point uses its environment (the air and certain objects) as the transmission medium.The access point can either transmit in the 2.4 to 2.5-GHz frequency range (802.11b/g radio) or the 5.2 GHz frequency range (802.11a radio), the actual range is country-dependent. Symbol devices, like other Ethernet devices, have unique, hardware encoded Media Access Control (MAC) or IEEE addresses. MAC addresses determine the device sending or receiving data. A MAC address is a 48-
bit number written as six hexadecimal bytes separated by colons. For example: 00:A0:F8:24:9A:C8 Also see the following sections:

Management Access Options 1.3.1 Cellular Coverage An access point establishes an average communication range with MUs called a Basic Service Set
(BSS) or cell. When in a particular cell, the MU associates and communicates with the access point supporting the radio coverage area of that cell. Adding access points to a single LAN establishes more cells to extend the range of the network. Configuring the same ESSID (Extended Service Set Identifier) on all access points makes them part of the same Wireless LAN. Introduction 1-21 access points with the same ESSID defines a coverage area. A valid ESSID is an alphanumeric, case-
sensitive identifier up to 32 characters. An MU searches for an access point with a matching ESSID and synchronizes (associates) to establish communications. This device association allows MUs within the coverage area to move about or roam. As the MU roams from cell to cell, it associates with a different access point. The roam occurs when the MU analyzes the reception quality at a location and determines a different access point provides better signal strength and lower MU load distribution. If the MU does not find an access point with a workable signal, it can perform a scan to find any AP. As MUs switch APs, the AP updates its association statistics. The user can configure the ESSID to correspond to up to 16 WLANs on each 802.11a or 802.11b/g radio. A Wireless Local Area Network (WLAN) is a data-communications system that flexibly extends the functionalities of a wired LAN. A WLAN does not require lining up devices for line-of-sight transmission, and are thus, desirable. Within the WLAN, roaming users can be handed off from one access point to another like a cellular phone system. WLANs can therefore be configured around the needs of specific groups of users, even when they are not in physical proximity. 1.3.2 MAC Layer Bridging The access point provides MAC layer bridging between its interfaces. The access point monitors traffic from its interfaces and, based on frame address, forwards the frames to the proper destination. The access point tracks source and destination addresses to provide intelligent bridging as MUs roam or network topologies change. The access point also handles broadcast and multicast messages and responds to MU association requests. The access point listens to all packets on its LAN and WAN interfaces and builds an address database using MAC addresses. An address in the database includes the interface media that the device uses to associate with the access point. The access point uses the database to forward packets from one interface to another. The bridge forwards packets addressed to unknown systems to the Default Interface (Ethernet). The access point internal stack interface handles all messages directed to the access point. Each access point stores information on destinations and their interfaces to facilitate forwarding. When a user sends an ARP (Address Resolution Protocol) request packet, the access point forwards it over all enabled interfaces except over the interface the ARP request packet was received. On receiving the ARP response packet, the access point database keeps a record of the destination address along with the receiving interface. With this information, the access point forwards any 1-22 AP-51xx Access Point Product Reference Guide directed packet to the correct destination. Transmitted ARP request packets echo back to other MUs. The access point removes from its database the destination or interface information that is not used for a specified time. The AP refreshes its database when it transmits or receives data from these destinations and interfaces. 1.3.3 Media Types The access point radio interface conforms to IEEE 802.11a/b/g specifications. The interface operates at a maximum 54Mbps (802.11a radio) using direct-sequence radio technology. The access point supports multiple-cell operations with fast roaming between cells. Within a direct-sequence system, each cell can operates independently. Adding cells to the network provides increased coverage area and total system capacity. The RS-232 serial port provides a Command Line Interface (CLI) connection. The serial link supports a direct serial connection. The access point is a Data Terminal Equipment (DTE) device with male pin connectors for the RS-232 port. Connecting the access point to a PC requires a null modem serial cable. 1.3.4 Direct-Sequence Spread Spectrum Spread spectrum (broadband) uses a narrowband signal to spread the transmission over a segment of the radio frequency band or spectrum. Direct-sequence is a spread spectrum technique where the transmitted signal is spread over a particular frequency range. The Symbol access point uses Direct-
Sequence Spread Spectrum (DSSS) for radio communication. Direct-sequence systems communicate by continuously transmitting a redundant pattern of bits called a chipping sequence. Each bit of transmitted data is mapped into chips by the access point and rearranged into a pseudorandom spreading code to form the chipping sequence. The chipping sequence is combined with a transmitted data stream to produce the AP -5131s output signal. MUs receiving a direct-sequence transmission use the spreading code to map the chips within the chipping sequence back into bits to recreate the original data transmitted by the access point. Intercepting and decoding a direct-sequence transmission requires a predefined algorithm to associate the spreading code used by the transmitting access point to the receiving MU. This algorithm is established by IEEE 802.11b specifications. The bit redundancy within the chipping sequence enables the receiving MU to recreate the original data pattern, even if bits in the chipping sequence are corrupted by interference. Introduction 1-23 The ratio of chips per bit is called the spreading ratio. A high spreading ratio increases the resistance of the signal to interference. A low spreading ratio increases the bandwidth available to the user. The access point uses different modulation schemes to encode more bits per chip at higher data rates. The access point is capable of a maximum 54Mbps data transmission rate (802.11a radio), but the coverage area is less than that of access point operating at lower data rates since coverage area decreases as bandwidth increases. 1.3.5 MU Association Process An access point recognizes MUs as they begin the association process with the access point. An access point keeps a list of the MUs it services. MUs associate with an access point based on the following conditions:
Signal strength between the access pointand MU
Number of MUs currently associated with the access point
MUs encryption and authentication capabilities
MUs supported data rate MUs perform pre-emptive roaming by intermittently scanning for access points and associating with the best available access point. Before roaming and associating, MUs perform full or partial scans to collect access point statistics and determine the direct-sequence channel used by the access point. Scanning is a periodic process where the MU sends out probe messages on all channels defined by the country code. The statistics enable an MU to reassociate by synchronizing its channel to the access point. The MU continues communicating with that access point until it needs to switch cells or roam. MUs perform partial scans at programmed intervals, when missing expected beacons or after excessive transmission retries. In a partial scan, the MU scans access points classified as proximate on the access point table. For each channel, the MU tests for Clear Channel Assessment (CCA). The MU broadcasts a probe with the ESSID and broadcast BSS_ID when the channel is transmission-free. It sends an ACK to a directed probe response from the access point and updates the table. An MU can roam within a coverage area by switching access points. Roaming occurs when:
Unassociated MU attempts to associate or reassociate with an available access point
Supported rate changes or the MU finds a better transmit rate with another access point
RSSI (received signal strength indicator) of a potential access point exceeds the current access point
Ratio of good-transmitted packets to attempted-transmitted packets falls below a threshold. 1-24 AP-51xx Access Point Product Reference Guide An MU selects the best available access point and adjusts itself to the access point direct-sequence channel to begin association. Once associated, the access point begins forwarding frames addressed to the target MU. Each frame contains fields for the current direct-sequence channel. The MU uses these fields to resynchronize to the access point. The scanning and association process continues for active MUs. This process allows the MUs to find new access points and discard out-of-range or deactivated access points. By testing the airwaves, the MUs can choose the best network connection available. 1.3.6 Operating Modes The access point can operate in a couple of configurations.
Access Point - As an Access Point, the access point functions as a layer 2 bridge (similar to Symbols existing AP-4131 access point). The wired uplink can operate as a trunk and support multiple VLANs. Up to 16 WLANs can be defined and mapped to access point WLANs. Each WLAN can be configured to be broadcast by one or both access point radios
(unlike the AP-4131 model access point). An AP-5131 or AP-5181 can operate in both an Access Point mode and Wireless Gateway/Router mode simultaneously. The network architecture and access point configuration define how the Access Point and Wireless Gateway/Router mode are negotiated.
Wireless Gateway/Router - If operating as a Wireless Gateway/Router, the access point functions as a router between two layer 2 networks: the WAN uplink (the ethernet port) and the Wireless side. The following options are available providing a solution for single-cell deployment:
PPPoE - The WAN interface can terminate a PPPoE connection, thus enabling the access point to operate in conjunction with a DSL or Cable modem to provide WAN connectivity.
NAT - (Network Address Translation) on the Wireless interface. Using NAT, the access point router is able to manage a private IP scheme. NAT allows translation of private addresses to the WAN IP address.
DHCP - On the Wireless side, the access point can assign private IP addresses.
Firewall - In between the WAN and Wireless interfaces, a Firewall protects against a number of known attacks. Introduction 1-25 1.3.7 Management Access Options Managing the access point includes viewing network statistics and setting configuration options. Statistics track the network activity of associated MUs and data transfers on the AP interfaces. The access point requires one of the following connection methods to perform a custom installation and manage the network:
Secure Java-Based WEB UI - (use Sun Microsystems JRE 1.5 or higher available from Suns Web site and be sure to disable Microsofts Java Virtual Machine if installed)
Command Line Interface (CLI) via Serial, Telnet and SSH
Config file - Human-readable; Importable/Exportable via FTP and TFTP
MIB (Management Information Base) accessing the access point SNMP function using a MIB Browser. The AP-5131 or AP-5181 downloads site contains the following 2 MIB files:
Symbol-CC-WS2000-MIB-2.0 (standard Symbol MIB file)
Symbol-AP-5131-MIB (AP-5131 and AP-5181 specific MIB file) Make configuration changes to access points individually. Optionally, use the access point import/
export configuration function to download access points settings to other access points. For detailed information, see Importing/Exporting Configurations on page 4-36. 1-26 AP-51xx Access Point Product Reference Guide Hardware Installation An access point installation includes mounting the access point, connecting the access point to the network (LAN or WAN port connection), connecting antennae and applying power.

Dual-Band Antennae. NOTE An AP-5131 or AP-5181 model access point optimally uses 2 antennae for the single-radio model and 4 antennae for the dual-radio model. 2.4 Access Point Placement For optimal performance, install the access point (regardless of model) away from transformers, heavy-duty motors, fluorescent lights, microwave ovens, refrigerators and other industrial equipment. Signal loss can occur when metal, concrete, walls or floors block transmission. Install the access point in open areas or add access points as needed to improve coverage. Antenna coverage is analogous to lighting. Users might find an area lit from far away to be not bright enough. An area lit sharply might minimize coverage and create dark areas. Uniform antenna placement in an area (like even placement of a light bulb) provides even, efficient coverage. Place the access point using the following guidelines:
Install the access point at an ideal height of 10 feet from the ground.
Orient the access point antennae vertically for best reception.
Point the access point antenna(s) downward if attaching to the ceiling. Symbol recommends conducting a site survey to define and document radio interference obstacles before installing the access point to maximize its radio coverage area. 2-6 AP-51xx Access Point Product Reference Guide 2.4.1 Site Surveys A site survey analyzes the installation environment and provides users with recommendations for equipment and placement. The optimum placement of 802.11a access points differs from 802.11b/g access points, because the locations and number of access points required are different to support the radio coverage area. Symbol recommends conducting a new site survey and developing a new coverage area floor plan when switching from 2 or 11Mbps access points (AP-3021 or AP-4131 models) to 54Mbps access points (AP-5131 and AP-5181 models), as the device placement requirements are significantly different. 2.4.2 Antenna Options 2.4.2.1 AP-5131 Antenna Options Both Radio 1 and Radio 2 require one antenna and can optimally use two antennae per radio (4 antennae total for dual-radio models). Two antennae per radio provides diversity that can improve performance and signal reception. Symbol supports two antenna suites for the AP-5131. One antenna suite supporting the 2.4 GHz band and another antenna suite supporting the 5.2 GHz band. Select an antenna model best suited to the intended operational environment of your AP-5131. NOTE On a single-radio AP-5131, Radio 1 can be configured to be either a 2.4 GHz or 5.2 GHz radio. On a dual-radio model, Radio 1 refers to the AP-
5131s 2.4 GHz radio and Radio 2 refers to the AP-5131 5.2 GHz radio. However, there could be some cases where a dual-radio AP-5131 is performing a Rogue AP detector function. In this scenario, the AP-5131 is receiving in either 2.4 GHz or 5.2 GHz over the Radio 1 or Radio 2 antennae depending on which radio is selected for the scan. Antenna connectors for Radio 1 are located in a different location from the Radio 2 antenna connectors. On single radio versions, the R-SMA connectors can support both bands and should be connected to a R-SMA dual-band antenna or an appropriate single band antenna. If necessary a R-
SMA to R-BNC adapter (Part No. 25-72178-01) can be purchased separately from Symbol. Hardware Installation 2-7 The AP-5131 2.4 GHz antenna suite includes the following models:
Symbol Part Number ML-2499-11PNA2-01R ML-2499-HPA3-01R ML-2499-BYGA2-01R ML-2452-APA2-01 Antenna Type Wide Angle Directional Omni-Directional Antenna Yagi Antenna Dual-Band Nominal Net Gain (dBi) 8.5 3.3 13.9 3.0 NOTE An additional adapter is required to use ML-2499-11PNA2-01 and ML-2499-BYGA2-01 model antennae. Please contact Symbol for more information. The AP-5131 5.2 GHz antenna suite includes the following models:

Symbol Power Injector (Part No. AP-PSBIAS-1P2-AFR)
Symbol 48-Volt Power Supply (Part No. 50-24000-050)
Any standard 802.3af compliant device. 2.5.2 AP-5181 Power Options The power options for the AP-5181 include:
!
CAUTION An AP-5181 model access point cannot use the AP-5131 recommended Symbol 48-Volt Power Supply (Part No. 50-24000-050). However, Symbol does recommend the AP-PSBIAS-5181-01R model power supply for use the AP-5181.
Symbol Power Injector (Part No. AP-PSBIAS-1P2-AFR)
Symbol (AP-5181 specific) 48-Volt Power Supply (Part No. AP-PSBIAS-5181-01R)
Any standard 802.3af compliant device. Hardware Installation 2-9 2.6 Symbol Power Injector System The access point can receive power either directly form a Symbol 48V AC-DC power supply or via an Ethernet cable connected to the LAN port (using the 802.3af standard). When users purchase a Symbol WLAN solution, they often need to place access points in obscure locations. In the past, a dedicated power source was required for each access point in addition to the Ethernet infrastructure. This often required an electrical contractor to install power drops at each access point location. An approved power injector solution merges power and Ethernet into one cable, reducing the burden of installation and allows optimal access point placement in respect to the intended radio coverage area. The Symbol Power Injector is included in certain AP-5131 and AP-5181 kits. The Symbol Power Injector (Part No. AP-PSBIAS-1P2-AFR) is an integrated AC-DC converter and 802.3af power injector which requires 110-220V AC power to combine low-voltage DC with Ethernet data in a single cable connecting to the access point. The access point can only use a Power Injector when connected to the LAN port. The Symbol AP-5131 and AP-5181 Power Supply (Part Numbers 50-24000-050 and AP-PSBIAS-5181-01R respectively) are not included in the kit and must be orderable separately as an accessory.
!
CAUTION The access point supports any standards-based 802.3af compliant power source (including non-Symbol power sources). However, using the wrong solution (including a POE system used on a legacy Symbol access point) could severely damage the access point and void the product warranty. A separate power injector is required for each access point comprising the network. 2.6.1 Installing the Power Injector Refer to the following sections for information on planning, installing, and validating the power injector installation:
Preparing for Site Installation
Cabling the Power Injector
Power Injector LED Indicators 2-10 AP-51xx Access Point Product Reference Guide 2.6.1.1 Preparing for Site Installation The power injector can be installed free standing, on an even horizontal surface or wall mounted using the power injectors wall mounting key holes. The following guidelines should be adhered to before cabling the power injector to an Ethernet source and an access point:
Do not block or cover airflow to the power injector.
Keep the power injector away from excessive heat, humidity, vibration and dust.
The power injector is not a repeater, and does not amplify the Ethernet data signal. For optimal performance, ensure the power injector is placed as close as possible to the network data port. 2.6.1.2 Cabling the Power Injector To install the power injector to an Ethernet data source and access point:

Managing the access point includes viewing network statistics and setting configuration options. The access point requires one of the following connection methods to manage the network:
Secure Java-Based WEB UI - (use Sun Microsystems JRE 1.5 or higher available from Suns Web site. Disable Microsofts Java Virtual Machine if installed). For information on using the Web UI to set access point default configuration values, see Basic Device Configuration on page 3-3 or chapters 4 through 7 of this guide.
Command Line Interface (CLI) via Serial, Telnet and SSH. The access point CLI is accessed through the RS232 port, via Telnet or SSH. The CLI follows the same configuration conventions as the device user interface with a few documented exceptions. For details on using the CLI to manage the access point, see Appendix 8, Command Line Interface Reference on page 8-1. Getting Started 3-3
Config file - Readable text file; Importable/Exportable via FTP, TFTP and HTTP. Configuration settings for an access point can be downloaded from the current configuration of another access point meeting the import/export requirements. For information on importing or exporting configuration files, see Importing/Exporting Configurations on page 4-36.
MIB (Management Information Base) accessing the access point SNMP functions using a MIB Browser. The access point download package contains the following 2 MIB files:
Symbol-CC-WS2000-MIB-2.0 (standard Symbol MIB file)
Symbol-AP-5131-MIB (AP-5131 specific MIB file) 3.3 Basic Device Configuration For the basic setup described in this section, the Java-based Web UI will be used to configure the access point. Use the access points LAN interface for establishing a link with the access point. Configure the access point as a DHCP client. For optimal screen resolution, set your screen resolution to 1024 x 768 pixels or greater. 1. Start Internet Explorer and enter the following IP address in the address field: 192.168.0.1. The access point login screen displays. NOTE DNS names are not supported as a valid IP address for the access point. The user is required to enter a numerical IP address. NOTE For optimum compatibility, use Sun Microsystems JRE 1.5 or higher
(available from Suns Website), and be sure to disable Microsofts Java Virtual Machine if installed. 3-4 AP-51xx Access Point Product Reference Guide 2. 3. Log in using admin as the default User ID and symbol as the default Password. Though the example above is for an AP-5131, there is no difference for an AP-5181. If the default login is successful, the Change Admin Password window displays. Change the password. Enter the current password and a new admin password in fields provided, and click Apply. Once the admin password has been updated, a warning message displays stating the access point must be set to a country. Getting Started 3-5 The export function will always export the encrypted Admin User password. The import function will import the Admin Password only if the access point is set to factory default. If the access point is not configured to factory default settings, the Admin User password WILL NOT get imported. NOTE Though the access point can have its basic settings defined using a number of different screens, Symbol recommends using the access point Quick Setup screen to set the correct country of operation and define its minimum required configuration from one convenient location. 3.3.1 Configuring Device Settings Configure a set of minimum required device settings within the Quick Setup screen. The values defined within the Quick Setup screen are also configurable in numerous other locations within the menu tree. When you change the settings in the Quick Setup screen, the values also change within the screen where these parameters also exist. Additionally, if the values are updated in these other screens, the values initially set within the Quick Setup screen will be updated. To define a basic access point configuration:
1. Select System Configuration -> Quick Setup from the menu tree, if the Quick Setup screen is not already displayed. 2. Enter a System Name for the access point. The System Name is useful if multiple Symbol devices are being administered. 3. Select the Country for the access points country of operation from the drop-down menu The access point prompts the user for the correct country code on the first login. A warning message also displays stating that an incorrect country settings may result in illegal radio operation. Selecting the correct country is central to legally operating the access point. Each country has its own regulatory restrictions concerning electromagnetic emissions and the maximum RF signal strength that can be transmitted. To ensure compliance with national and local laws, be sure to set the Country accurately. CLI and MIB users cannot configure their access point until a two character country code (for example, United States - us) is set. Refer to Appendix A, Country Codes on page A-7 for the two character country codes. NOTE The System Name and Country are also configurable within the System Settings screen. Refer to Configuring System Settings on page 4-2 (if necessary) to set a system location and admin email address for the access point or to view other default settings. 3-6 AP-51xx Access Point Product Reference Guide 4. Optionally enter the IP address of the server used to provide system time to the access point within the Time Server field. NOTE DNS names are not supported as a valid IP address. The user is required to enter a numerical IP address. Once the IP address is entered, the access points Network Time Protocol (NTP) functionality is engaged automatically. Refer to the access point Product Reference Guide for information on defining alternate time servers and setting a synchronization interval for the access point to adjust its displayed time. Refer to Configuring Network Time Protocol (NTP) on page 4-31
(if necessary) for information on setting alternate time servers and setting a synchronization interval for the access point to adjust its displayed time. 5. Click the WAN tab to set a minimum set of parameters for using the WAN interface. a. Select the Enable WAN Interface checkbox to enable a connection between the access point and a larger network or outside world through the WAN port. Disable this option to effectively isolate the access points WAN connection. No connections to a larger network or the Internet will be possible. MUs cannot communicate beyond the configured subnets. b. Select the This Interface is a DHCP Client checkbox to enable DHCP for the access point WAN connection. This is useful, if the larger corporate network or Internet Service Provider (ISP) uses DHCP. DHCP is a protocol that includes mechanisms for IP address allocation and delivery of host-specific configuration parameters from a DHCP server to a host. Some of these parameters are IP address, network mask, and gateway. NOTE Symbol recommends that the WAN and LAN ports should not both be configured as DHCP clients. c. Specify an IP address for the access points WAN connection. An IP address uses a series of four numbers expressed in dot notation, for example, 190.188.12.1 (no DNS names supported). d. Specify a Subnet Mask for the access points WAN connection. This number is available from the ISP for a DSL or cable-modem connection, or from an administrator if the access point connects to a larger network. A subnet mask uses a series of four numbers expressed in dot notation. For example, 255.255.255.0 is a valid subnet mask. Getting Started 3-7 e. Define a Default Gateway address for the access points WAN connection. The ISP or a network administrator provides this address. f. Specify the address of a Primary DNS Server. The ISP or a network administrator provides this address. 6. Optionally, use the Enable PPP over Ethernet checkbox to enable Point-to-Point over Ethernet (PPPoE) for a high-speed connection that supports this protocol. Most DSL providers are currently using or deploying this protocol. PPPoE is a data-link protocol for dialup connections. PPPoE will allow the access point to use a broadband modem (DSL, cable modem, etc.) for access to high-speed data networks. a. Select the Keep Alive checkbox to enable occasional communications over the WAN port even when client communications to the WAN are idle. Some ISPs terminate inactive connections, while others do not. In either case, enabling Keep-Alive maintains the WAN connection, even when there is no traffic. If the ISP drops the connection after the idle time, the access point automatically reestablishes the connection to the ISP. b. Specify a Username entered when connecting to the ISP. When the Internet session begins, the ISP authenticates the username. c. Specify a Password entered when connecting to the ISP. When the Internet session starts, the ISP authenticates the password. For additional access point WAN port configuration options, see Configuring WAN Settings on page 5-14. 7. Click the LAN tab to set a minimum set of parameters to use the access point LAN interface. a. Select the Enable LAN Interface checkbox to forward data traffic over the access point LAN connection. The LAN connection is enabled by default. b. Use the This Interface drop-down menu to specify how network address information is defined over the access points LAN connection. Select DHCP Client if the larger corporate network uses DHCP. DHCP is a protocol that includes mechanisms for IP address allocation and delivery of host-specific configuration parameters from a DHCP server to a host. Some of these parameters are IP address, network mask, and gateway. Select DHCP Server to use the access point as a DHCP server over the LAN connection. Select the Bootp client option to enable a diskless system to discover its own IP address. NOTE Symbol recommends that the WAN and LAN ports should not both be configured as DHCP clients. 3-8 AP-51xx Access Point Product Reference Guide c. If using the static or DHCP Server option, enter the network-assigned IP Address of the access point. NOTE DNS names are not supported as a valid IP address for the access point. The user is required to enter a numerical IP address. e. d. The Subnet Mask defines the size of the subnet. The first two sets of numbers specify the network domain, the next set specifies the subset of hosts within a larger network. These values help divide a network into subnetworks and simplify routing and data transmission. If using the static or DHCP Server option, enter a Default Gateway to define the numerical IP address of a router the access point uses on the Ethernet as its default gateway. If using the static or DHCP Server option, enter the Primary DNS Server numerical IP address. If using the DHCP Server option, use the Address Assignment Range parameter to specify a range of IP address reserved for mapping clients to IP addresses. If a manually
(static) mapped IP address is within the IP address range specified, that IP address could still be assigned to another client. To avoid this, ensure all statically mapped IP addresses are outside of the IP address range assigned to the DHCP server. g. f. 8. For additional access point LAN port configuration options, see Configuring the LAN Interface on page 5-1. Enable the radio(s) using the Enable checkbox(es) within the Radio Configuration field. If using a single radio access point, enable the radio, then select either 2.4 GHz or 5.2 GHz from the RF Band of Operation field. Only one RF band option at a time is permissible in a single-radio model. If using a dual-radio model, the user can enable both RF bands. For additional radio configuration options, see Configuring the 802.11a or 802.11b/g Radio on page 5-47. 9. Select the WLAN #1 tab (WLANs 1 - 4 are available within the Quick Setup screen) to define its ESSID and security scheme for basic operation. NOTE A maximum of 16 WLANs are configurable within the Wireless Configuration screen. The limitation of 16 WLANs exists regardless of whether the access point is a single or dual-radio model. Getting Started 3-9 a. Enter the Extended Services Set Identification (ESSID) and name associated with the WLAN. For additional information on creating and editing up to 16 WLANs per access point, see Creating/Editing Individual WLANs on page 5-24. b. Use the Available On checkboxes to define whether the target WLAN is operating over the 802.11a or 802.11b/g radio. Ensure the radio selected has been enabled (see step 8). c. Even an access point configured with minimal values must protect its data against theft and corruption. A security policy should be configured for WLAN1 as part of the basic configuration outlined in this guide. A security policy can be configured for the WLAN from within the Quick Setup screen. Policies can be defined over time and saved to be used as needed as security requirements change. Symbol recommends you familiarize yourself with the security options available on the access point before defining a security policy. Refer to Configuring WLAN Security Settings on page 3-9. 10. Click Apply to save any changes to the access point Quick Setup screen. Navigating away from the screen without clicking Apply results in all changes to the screens being lost. 11. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on the access point Quick Setup screen to the last saved configuration. 3.3.1.1 Configuring WLAN Security Settings To configure a basic security policy for a WLAN:
1. From the access point Quick Setup screen, click the Create button to the right of the Security Policy item. The New Security Policy screen displays with the Manually Pre-shared key/No authentication and No Encryption options selected. Naming and saving such a policy (as is) would provide no security and might only make sense in a guest network wherein no sensitive data is either transmitted or received. Consequently, at a minimum, a basic security scheme (in this case WEP 128) is recommended in a network environment wherein sensitive data is transmitted. NOTE For information on configuring the other encryption and authentication options available to the access point, see Configuring Security Options on page 6-2. 2. Ensure the Name of the security policy entered suits the intended configuration or function of the policy. 3-10 AP-51xx Access Point Product Reference Guide Multiple WLANs can share the same security policy, so be careful not to name security policies after specific WLANs or risk defining a WLAN to single policy. Symbol recommends naming the policy after the attributes of the authentication or encryption type selected. 3. Select the WEP 128 (104 bit key) checkbox. The WEP 128 Settings field displays within the New Security Policy screen. 4. Configure the WEP 128 Settings field as required to define the Pass Key used to generate the WEP keys. Pass Key Specify a 4 to 32 character pass key and click the Generate button. The access point, other proprietary routers and Symbol MUs use the same algorithm to convert an ASCII string to the same hexadecimal number. Non-Symbol clients and devices need to enter WEP keys manually as hexadecimal numbers. The access point and its target client(s) must use the same pass key to interoperate. Getting Started 3-11 Keys #1-4 Use the Key #1-4 fields to specify key numbers. The key can be either a hexidecimal or ASCII depending on which option is selected from the drop-down menu. For WEP 64 (40-bit key), the keys are 10 hexadecimal characters in length or 5 ASCII characters. For WEP 128 (104-bit key), the keys are 26 hexadecimal characters in length or 13 ASCII characters. Select one of these keys for activation by clicking its radio button. The access point and its target client(s) must use the same key to interoperate. 5. Click the Apply button to save the security policy and return to the access point Quick Setup screen. At this point, you can test the access point for MU interoperability. 3.3.2 Testing Connectivity Verify the access points link with an MU by sending Wireless Network Management Protocol
(WNMP) ping packets to the associated MU. Use the Echo Test screen to specify a target MU and configure the parameters of the test. The WNMP ping test only works with Symbol MUs. Only use a Symbol MU to test access point connectivity using WNMP. NOTE Before testing for connectivity, the target MU needs to be set to the same ESSID as the access point. Since WEP 128 has been configured for the access point, the MU also needs to be configured for WEP 128 and use the same WEP keys. Ensure the MU is associated with the access point before testing for connectivity. To ping a specific MU to assess its connection with an access point:
1. Select Status and Statistics -> MU Stats from the menu tree. 2. Select the Echo Test button from within the MU Stats Summary screen. 3. Define the following parameters for the test. Station Address The station address is the IP address of the target MU. Refer to the MU Stats Summary screen for associated MU IP address information. Number of pings Defines the number of packets to be transmitted to the MU. The default is 100. 3-12 AP-51xx Access Point Product Reference Guide Packet Length Specifies the length of each packet transmitted to the MU during the test. The default length is 100 bytes. 4. Click the Ping button to begin transmitting packets to the specified MU address. Refer to the Number of Responses value to assess the number of responses from the MU versus the number of ping packets transmitted by the access point. Use the ratio of packets sent versus the number of packets received the link quality between the MU and the access point. Click the OK button to exit the Echo Test screen and return to the MU Stats Summary screen. 3.3.3 Where to Go from Here?

To configure System Settings for the access point:
1. Select System Configuration -> System Settings from the access point menu tree. 2. Configure the access point System Settings field to assign a system name and location, set the country of operation and view device version information. System Configuration 4-3 System Name System Location Specify a device name for the access point. Symbol recommends selecting a name serving as a reminder of the user base the access point supports (engineering, retail, etc.). Enter the location of the access point. The System Location parameter acts as a reminder of where the AP can be found. Use the System Name field as a specific identifier of device location. Use the System Name and System Location fields together to optionally define the AP name by the radio coverage it supports and specific physical location. For example, second floor engineering Admin Email Address Specify the AP administrator's email address. Country The access point prompts the user for the correct country code after the first login. A warning message also displays stating that an incorrect country setting will lead to an illegal use of the access point. Use the pull-down menu to select the country of operation. Selecting the correct country is extremely important. Each country has its own regulatory restrictions concerning electromagnetic emissions (channel range) and the maximum RF signal strength transmitted. To ensure compliance with national and local laws, be sure to set the Country field correctly. If using the access point configuration file, CLI or MIB to configure the access points country code, see Country Codes on page A-7. access point Version The displayed number is the current version of the access point System Uptime Serial Number device firmware. Use this information to determine if the AP is running the most recent firmware available from Symbol. Use the Firmware Update screen to keep the APs firmware up to date. For more information, see Updating Device Firmware on page 4-40. Displays the current uptime of the access point defined in the System Name field. System Uptime is the cumulative time since the access point was last rebooted or lost power. Displays the access point Media Access Control (MAC) address. The access point MAC address is hard coded at the factory and cannot be modified. The LAN and WAN port MAC addresses can be located within the LAN and WAN Stats screens. For information on locating the access point MAC addresses, see Viewing WAN Statistics on page 7-2 and Viewing LAN Statistics on page 7-6. 4-4 AP-51xx Access Point Product Reference Guide 3. Refer to the Factory Defaults field to restore either a full or partial default configuration.

(once the reboot is done) by performing an Apply operation from the WEB UI or a save operation from the CLI. 5. Click Apply to save any changes to the System Settings screen. Navigating away from the screen without clicking the Apply button results in all changes to the screen being lost. System Configuration 4-5 NOTE The Apply button is not needed for restoring the access point default configuration or restarting the access point. 6. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on the System Settings screen to the last saved configuration. 7. Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. 4.2 Configuring Data Access Use the access point Access screen to enable/disable data throughput to the access points LAN1, LAN2 and/or WAN interfaces and display screens for changing administrator passwords. Use the access point Access screen checkboxes to enable or disable LAN1, LAN2 and/or WAN access using the protocols and ports listed. If access is disabled, this effectively locks out the administrator from configuring the access point using that interface. To avoid jeopardizing the network data managed by the access point, Symbol recommends enabling only those interfaces used in the routine
(daily) management of the network, and disabling all other interfaces until they are required. To configure access for the access point:
1. Select System Configuration -> access point Access from the access point menu tree. 4-6 AP-51xx Access Point Product Reference Guide 2. Use the access point Access field checkboxes to enable/disable the following on the access points LAN1, LAN2 or WAN interfaces:
Applet HTTP (port 80) Select the LAN1, LAN2 and/or WAN checkboxes to enable access Applet HTTPS (port 443) CLI TELNET (port 23) CLI SSH (port 22) SNMP (port 161) to the access point configuration applet using a Web browser. Select the LAN1, LAN2 and/or WAN checkboxes to enable access to the access point configuration applet using a Secure Sockets Layer (SSL) for encrypted HTTP sessions. Select the LAN1, LAN2 and/or WAN checkboxes to enable access to the access point CLI via the TELNET terminal emulation TCP/IP protocol. Select the LAN1, LAN2 and/or WAN checkboxes to enable access to the access point CLI using the SSH (Secure Shell) protocol. Select the LAN1, LAN2 and/or WAN checkboxes to enable access to the access point configuration settings from an SNMP-capable client. 3. Refer to the Applet Timeout field to set an HTTPS timeout interval. HTTP/S Timeout Disables access to the access point if no data activity is detected over Applet HTTPS (port 443) after the user defined interval. Default is 0 Mins. System Configuration 4-7 4. Configure the Secure Shell field to set timeout values to reduce network inactivity. Authentication Timeout SSH Keepalive Interval Defines the maximum time (between 30 - 120 seconds) allowed for SSH authentication to occur before executing a timeout. The minimum permissible value is 30 seconds. The SSH Keepalive Interval defines a period (in seconds) after which if no data has been received from a client, SSH sends a message through the encrypted channel to request a response from the client. The default is 0, and no messages will be sent to the client until a non-zero value is set. Defining a Keepalive interval is important, otherwise programs running on a server may never notice if the other end of a connection is rebooted. 5. Use the Admin Authentication buttons to specify the authentication server connection method. Local Radius The access point verifies the authentication connection. Designates that a Radius server is used in the authentication credential verification. If using this option, the connected PC is required to have its Radius credentials verified with an external Radius server. Additionally, the Radius Servers Active Directory should have a valid user configured and have a PAP based Remote Access Policy configured for Radius Admin Authentication to work. 6. Use the Radius Server if a Radius server has been selected as the authentication server, enter the required network address information. Radius Server IP Port Specify the numerical (non DNS name) IP address of the Remote Authentication Dial-In User Service (Radius) server. Radius is a client/server protocol and software enabling remote-access servers to communicate with a server used to authenticate users and authorize access to the requested system or service. Specify the port on which the server is listening. The Radius server typically listens on ports 1812 (default port). 4-8 AP-51xx Access Point Product Reference Guide Shared Secret Define a shared secret for authentication on the server. The shared secret is required to be the same as the shared secret defined on the Radius server. Use shared secrets to verify Radius messages
(with the exception of the Access-Request message) sent by a Radius-enabled device configured with the same shared secret. Apply the qualifications of a well-chosen password to the generation of a shared secret. Generate a random, case-sensitive string using letters, numbers and symbols. The default is symbol. 7. Update the Administrator Access field to change the administrative password used to access the access point configuration settings. Change Admin Password Click the Change Admin Password button to display a screen for updating the AP administrator password. Enter and confirm a new administrator password as required. 8. Click Apply to save any changes to the access point Access screen. Navigating away from the screen without clicking the Apply button results in all changes to the screen being lost. 9. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on the access point Access screen to the last saved configuration. 10. Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. 4.3 Managing Certificate Authority (CA) Certificates Certificate management includes the following sections:
Importing a CA Certificate
Creating Self Certificates for Accessing the VPN 4.3.1 Importing a CA Certificate A certificate authority (CA) is a network authority that issues and manages security credentials and public keys for message encryption. The CA signs all digital certificates that it issues with its own private key. The corresponding public key is contained within the certificate and is called a CA certificate. A browser must contain this CA certificate in its Trusted Root Library so that it can trust certificates signed by the CA's private key. System Configuration 4-9 Depending on the public key infrastructure, the digital certificate includes the owner's public key, the certificate expiration date, the owner's name and other public key owner information. The access point can import and maintain a set of CA certificates to use as an authentication option for Virtual Private Network (VPN) access. To use the certificate for a VPN tunnel, define a tunnel and select the IKE settings to use either RSA or DES certificates. For additional information on configuring VPN tunnels, see Configuring VPN Tunnels on page 6-33.
!
CAUTION Loaded and signed CA certificates will be lost when changing the access points firmware version using either the GUI or CLI. After a certificate has been successfully loaded, export it to a secure location to ensure its availability after a firmware update. Refer to your access point network administrator to obtain a CA certificate to import into the access point. NOTE Verify the access point device time is synchronized with an NTP server before importing a certificate to avoid issues with conflicting date/time stamps. For more information, see Configuring Network Time Protocol
(NTP) on page 4-31. To import a CA certificate:
1. Select System Configuration -> Certificate Mgmt -> CA Certificates from the access point menu tree. 4-10 AP-51xx Access Point Product Reference Guide 2. Copy the content of the CA Certificate message (using a text editor such as notepad) and then click on Paste from Clipboard. The content of the certificate displays in the Import a root CA Certificate field. 3. Click the Import root CA Certificate button to import it into the CA Certificate list. 4. Once in the list, select the certificate ID within the View Imported root CA Certificates field to view the certificate issuer name, subject, and certificate expiration data. To delete a certificate, select the Id from the drop-down menu and click the Del button. 5. 4.3.2 Creating Self Certificates for Accessing the VPN The access point requires two kinds of certificates for accessing the VPN, CA certificates and self certificates. Self certificates are certificate requests you create, send to a Certificate Authority (CA) to be signed, then import the signed certificate into the management system. CAUTION Self certificates can only be generated using the access point GUI and CLI interfaces. No functionality exists for creating a self-certificate using the access points SNMP configuration option.

System Configuration 4-17 4.4 Configuring SNMP Settings Simple Network Management Protocol (SNMP) facilitates the exchange of management information between network devices. SNMP uses Management Information Bases (MIBs) to manage the device configuration and monitor Internet devices in potentially remote locations. MIB information accessed via SNMP is defined by a set of managed objects called object identifiers (OIDs). An object identifier
(OID) is used to uniquely identify each object variable of a MIB. The access point Web download package contains the following 2 MIB files:
Symbol-CC-WS2000-MIB-2.0 (common Symbol MIB file)
Symbol-AP-5131-MIB (AP-5131 specific MIB file) NOTE The Symbol-AP-5131-MIB contains the majority of the information contained within the Symbol-CC-WS2000-MIB-2.0 file. This feature rich information has been validated with the Symbol WS2000 and proven reliable. The remaining portion of the Symbol-AP-5131-MIB contains supplemental information unique to the access point feature set. If using the Symbol-CC-WS2000-MIB-2.0 and/or Symbol-AP-5131-MIB to configure the AP-5131, use the table below to locate the MIB where the feature can be configured.

System Configuration 4-19 The access point SNMP agent functions as a command responder and is a multilingual agent responding to SNMPv1, v2c and v3 managers (command generators). The factory default configuration maintains SNMPv1/2c support of the community names, hence providing backward compatibility. SNMP v1/v2c community definitions and SNMP v3 user definitions work independently, and both use the Access Control List (ACL) of the SNMP Access Control sub-screen. Use the SNMP Access screen to define SNMP v1/v2c community definitions and SNMP v3 user definitions. SNMP version 1 (v1) provides a strong network management system, but its security is relatively weak. The improvements in SNMP version 2c (v2c) do not include the attempted security enhancements of other version-2 protocols. Instead, SNMP v2c defaults to SNMP-standard community strings for read-only and read/write access. SNMP version 3 (v3) further enhances protocol features, providing much improved security. SNMP v3 encrypts transmissions and provides authentication for users generating requests. To configure SNMP v1/v2c community definitions and SNMP v3 user definitions for the access point:
1. Select System Configuration - > SNMP Access from the access point menu tree. SNMP v1/v2c community definitions allow read-only or read/write access to access point management information. The SNMP community includes users whose IP addresses are specified on the SNMP Access Control screen. A read-only community string allows a remote device to retrieve information, while a read/
write community string allows a remote device to modify settings. Symbol recommends 4-20 AP-51xx Access Point Product Reference Guide considering adding a community definition using a site-appropriate name and access level. Set up a read/write definition (at a minimum) to facilitate full access by the access point administrator. 2. Configure the SNMP v1/v2 Configuration field (if SNMP v1/v2 is used) to add or delete community definitions, name the community, specify the OID and define community access. Add Delete Community OID Access Click Add to create a new SNMP v1/v2c community definition. Select Delete to remove a SNMP v1/v2c community definition. Use the Community field to specify a site-appropriate name for the community. The name is required to match the name used within the remote network management software. Use the OID (Object Identifier) pull-down list to specify a setting of All or a enter a Custom OID. Select All to assign the user access to all OIDs in the MIB. The OID field uses numbers expressed in dot notation. Use the Access pull-down list to specify read-only (R) access or read/write (RW) access for the community. Read-only access allows a remote device to retrieve access point information, while read/write access allows a remote device to modify access point settings. 3. Configure the SNMP v3 User Definitions field (if SNMP v3 is used) to add and configure SNMP v3 user definitions. SNMP v3 user definitions allow read-only or read/write access to management information as appropriate. Add Delete Username Click Add to create a new entry for an SNMP v3 user. Select Delete to remove an entry for an SNMP v3 user. Specify a username by typing an alphanumeric string of up to 31 characters. System Configuration 4-21 Security Level OID Passwords Access Use the Security Level area to specify a security level of noAuth
(no authorization), AuthNoPriv (authorization without privacy), or AuthPriv (authorization with privacy). The NoAuth setting specifies no login authorization or encryption for the user. The AuthNoPriv setting requires login authorization, but no encryption. The AuthPriv setting requires login authorization and uses the Data Encryption Standard (DES) protocol. Use the OID (Object Identifier) area to specify a setting of All or enter a Custom OID. Select All to assign the user access to all OIDs in the MIB. The OID field uses numbers expressed in dot notation. Select Passwords to display the Password Settings screen for specifying authentication and password settings for an SNMP v3 user. The maximum password length is 11 characters. Use the Authentication Algorithm drop-down menu to specify MD5 or SHA1 as the authentication algorithm. Use the Privacy Algorithm drop-down menu to define an algorithm of DES or AES-128bit. When entering the same username on the SNMP Traps and SNMP Access screens, the password entered on the SNMP Traps page overwrites the password entered on the SNMP Access page. To avoid this problem, enter the same password on both pages. Use the Access pull-down list to specify read-only (R) access or read/write (RW) access for a user. Read-only access permits a user to retrieve access point information, while read/write access allows a user to modify access pointsettings. 4. Specify the users who can read and optionally modify the SNMP-capable client. 4-22 AP-51xx Access Point Product Reference Guide SNMP Access Control Click the SNMP Access Control button to display the SNMP Access Control screen for specifying which users can read SNMP-generated information and potentially modify related settings from an SNMP-capable client. The SNMP Access Control screen's Access Control List (ACL) uses Internet Protocol (IP) addresses to restrict access to the APs SNMP interface. The ACL applies to both SNMP v3 user definitions and SNMP v1/v2c community definitions. For detailed instructions of configuring SNMP user access and modification privileges, see Configuring SNMP Access Control on page 4-22. 5. If configuring SNMP v3 user definitions, set the SNMP v3 engine ID. access point SNMP v3 Engine ID The access point SNMP v3 Engine ID field lists the unique SNMP v3 Engine ID for the access point. This ID is used in SNMP v3 as the source for a trap, response or report. It is also used as the destination ID when sending get, getnext, getbulk, set or inform commands. 6. Click Apply to save any changes to the SNMP Access screen. Navigating away from the screen without clicking the Apply button results in all changes to the screen being lost. 7. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on the SNMP Access screen to the last saved configuration. 8. Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. For additional SNMP configuration information, see:
Configuring SNMP Access Control
Enabling SNMP Traps
Configuring Specific SNMP Traps
Configuring SNMP RF Trap Thresholds 4.4.1 Configuring SNMP Access Control Use the SNMP Access Control screen (as launched from the SNMP Access screen) to specify which users can read SNMP generated information and, if capable, modify related settings from an SNMP-capable client. System Configuration 4-23 Use the SNMP Access Control screen's Access Control List (ACL) to limit, by Internet Protocol (IP) address, who can access the access point SNMP interface. NOTE The ACL applies to both SNMP v3 user definitions and SNMP v1/v2c community definitions on the access point SNMP Access screen. To configure SNMP user access control for the access point:
1. Select System Configuration - > SNMP Access from the access point menu tree. Click on the SNMP Access Control button from within the SNMP Access screen. 2. Configure the SNMP Access Control screen to add the IP addresses of those users receiving SNMP access. 4-24 AP-51xx Access Point Product Reference Guide Access Control List Add Edit Delete OK Cancel Enter Start IP and End IP addresses (numerical addresses only, no DNS names supported) to specify a range of user that can access the access point SNMP interface. An SNMP-capable client can be set up whereby only the administrator (for example) can use a read/
write community definition. Use just the Starting IP Address column to specify a single SNMP user. Use both the Starting IP Address and Ending IP Address columns to specify a range of addresses for SNMP users. To add a single IP address to the ACL, enter the same IP address in the Start IP and End IP fields. Leave the ACL blank to allow access to the SNMP interface from the IP addresses of all authorized users. Click Add to create a new ACL entry. Click Edit to revise an existing ACL entry. Click Delete to remove a selected ACL entry for one or more SNMP users. Click Ok to return to the SNMP Access screen. Click Apply within the SNMP Access screen to save any changes made on the SNMP Access Control screen. Click Cancel to undo any changes made on the SNMP Access Control screen. This reverts all settings for this screen to the last saved configuration. 4.4.2 Enabling SNMP Traps SNMP provides the ability to send traps to notify the administrator that trap conditions are met. Traps are network packets containing data relating to network devices, or SNMP agents, that send the traps. SNMP management applications can receive and interpret these packets, and optionally can perform responsive actions. SNMP trap generation is programmable on a trap-by-trap basis. Use the SNMP Traps Configuration screen to enable traps and to configure appropriate settings for reporting this information. Trap configuration depends on the network machine that receives the generated traps. SNMP v1/v2c and v3 trap configurations function independently. In a mixed SNMP environment, generated traps can be sent using configurations for both SNMP v1/v2c and v3. To configure SNMP traps on the access point:
System Configuration 4-25 1. Select System Configuration - > SNMP Access - > SNMP Trap Configuration from the access point menu tree. 2. Configure the SNMP v1/v2c Trap Configuration field (if SNMP v1/v2c Traps are used) to modify the following:
Add Delete Destination IP Port Community SNMP Version Click Add to create a new SNMP v1/v2c Trap Configuration entry. Click Delete to remove a selected SNMP v1/v2c Trap Configuration entry. Specify a numerical (non DNS name) destination IP address for receiving the traps sent by the access point SNMP agent. Specify a destination User Datagram Protocol (UDP) port for receiving traps. The default is 162. Enter a community name specific to the SNMP-capable client that receives the traps. Use the SNMP Version drop-down menu to specify v1 or v2. Some SNMP clients support only SNMP v1 traps, while others support SNMP v2 traps and possibly both, verify the correct traps are in use with clients that support them. 3. Configure the SNMP v3 Trap Configuration field (if SNMP v3 Traps are used) to modify the following:
4-26 AP-51xx Access Point Product Reference Guide Add Delete Destination IP Port Username Security Level Passwords Click Add to create a new SNMP v3 Trap Configuration entry. Select Delete to remove an entry for an SNMP v3 user. Specify a numerical (non DNS name) destination IP address for receiving the traps sent by the access point SNMP agent. Specify a destination User Datagram Protocol (UDP) port for receiving traps. Enter a username specific to the SNMP-capable client receiving the traps. Use the Security Level drop-down menu to specify a security level of noAuth (no authorization), AuthNoPriv (authorization without privacy), or AuthPriv (authorization with privacy). The NoAuth setting specifies no login authorization or encryption for the user. The AuthNoPriv setting requires login authorization, but no encryption. The AuthPriv setting requires login authorization and uses the Data Encryption Standard (DES). Select Passwords to display the Password Settings screen for specifying authentication and password settings for an SNMP v3 user. The maximum password length is 11 characters. Use the Authentication Algorithm drop-down menu to specify MD5 or SHA1 as the authentication algorithm. Use the Privacy Algorithm drop-down menu to define an algorithm of DES or AES-128bit. If entering the same username on the SNMP Traps and SNMP Access screens, the password entered on the SNMP Traps page overwrites the password entered on the SNMP Access page. To avoid this problem, enter the same password on both pages. 4. Click Apply to save any changes to the SNMP Trap Configuration screen. Navigating away from the screen without clicking the Apply button results in all changes to the screen being lost. 5. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on SNMP Trap Configuration screen to the last saved configuration. 6. Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. System Configuration 4-27 4.4.3 Configuring Specific SNMP Traps Use the SNMP Traps screen to enable specific traps on the access point. Symbol recommends defining traps to capture unauthorized devices operating within the access point coverage area. Trap configuration depends on the network machine that receives the generated traps. SNMP v1/v2c and v3 trap configurations function independently. In a mixed SNMP environment, traps can be sent using configurations for both SNMP v1/v2c and v3. To configure specific SNMP traps on the access point:
1. Select System Configuration - > SNMP Access - > SNMP Traps from the access point menu tree. 2. Configure the MU Traps field to generate traps for MU associations, MU association denials and MU authentication denials. When a trap is enabled, a trap is sent every 10 seconds until the condition no longer exists. MU associated MU unassociated Generates a trap when an MU becomes associated with one of the access points WLANs. Generates a trap when an MU becomes unassociated with (or gets dropped from) one of the access points WLANs. 4-28 AP-51xx Access Point Product Reference Guide MU denied association MU denied authentication Generates a trap when an MU is denied association to a access point WLAN. Can be caused when the maximum number of MUs for a WLAN is exceeded or when an MU violates the access points Access Control List (ACL). Generates a trap when an MU is denied authentication on one of the APs WLANs. Can be caused by the MU being set for the wrong authentication type for the WLAN or by an incorrect key or password. 3. Configure the SNMP Traps field to generate traps when SNMP capable MUs are denied authentication privileges or are subject of an ACL violation. When a trap is enabled, a trap is sent every 5 seconds until the condition no longer exists. SNMP authentication failures SNMP ACL violation Generates a trap when an SNMP-capable client is denied access to the access points SNMP management functions or data. This can result from an incorrect login, or missing/incorrect user credentials. Generates a trap when an SNMP client cannot access SNMP management functions or data due to an Access Control List (ACL) violation. This can result from a missing/incorrect IP address entered within the SNMP Access Control screen. 4. Configure the Network Traps field to generate traps when the access points link status changes or when the APs firewall detects a DOS attack. Physical port status change Denial of service
(DOS) attempts Send trap every Generates a trap whenever the status changes on the access point. The physical port status changes when a link is lost between the access point and a connected device. Generates a trap whenever a Denial of Service (DOS) attack is detected by the access point firewall. A new trap is sent at the specified interval until the attack has stopped. Defines the interval in seconds the access point uses to generate a trap until the Denial of Service attack is stopped. Default is 10 seconds. 5. Configure the System Traps field to generate traps when the access point re-initializes during transmission, saves its configuration file. When a trap is enabled, a trap is sent every 5 seconds until the condition no longer exists. System Configuration 4-29 System Cold Start Configuration Changes Rogue AP detection AP Radar detection WPA Counter Measure MU Hotspot Status Generates a trap when the access point re-initializes while transmitting, possibly altering the SNMP agent's configuration or protocol entity implementation. Generates a trap whenever changes to the access points configuration file are saved. Generates a trap if a Rogue AP is detected by the access point. Generates a trap if an AP is detected using a form of radar detection. Generates a trap if an attack is detected against the WPA Key Exchange Mechanism. Generates a trap when a change to the status of MU hotspot member is detected. 6. Click Apply to save any changes to the SNMP Traps screen. Navigating away from the screen without clicking the Apply button results in all changes to the screen being lost. 7. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on SNMP Traps screen to the last saved configuration. 8. Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. 4.4.4 Configuring SNMP RF Trap Thresholds Use the SNMP RF Trap Threshold screen as a means to track RF activity and the access points radio and associated MU performance. SNMP RF Traps are sent when RF traffic exceeds defined limits set in the RF Trap Thresholds field of the SNMP RF Traps screen. Thresholds are displayed for the access point, WLAN, selected radio and the associated MU. To configure specific SNMP RF Traps on the access point:
1. Select System Configuration - > SNMP Access - > SNMP RF Trap Thresholds from the access point menu tree. 4-30 AP-51xx Access Point Product Reference Guide 2. Configure the RF Trap Thresholds field to define device threshold values for SNMP traps. NOTE Average Bit Speed,% of Non-Unicast, Average Signal, Average Retries,%
Dropped and % Undecryptable are not access point statistics. Pkts/s Throughput Enter a maximum threshold for the total throughput in Pps (Packets per second). Set a maximum threshold for the total throughput in Mbps
(Megabits per second). Average Bit Speed Enter a minimum threshold for the average bit speed in Mbps
(Megabits per second). Average Signal Average Retries
% Dropped Enter a minimum threshold for the average signal strength in dBm for each device. Set a maximum threshold for the average number of retries for each device. Enter a maximum threshold for the total percentage of packets dropped for each device. Dropped packets can be caused by poor RF signal or interference on the channel. System Configuration 4-31
% Undecryptable Define a maximum threshold for the total percentage of packets undecryptable for each device. Undecryptable packets can be the result of corrupt packets, bad CRC checks or incomplete packets. Associated MUs Set a maximum threshold for the total number of MUs associated with each device. 3. Configure the Minimum Packets field to define a minimum packet throughput value for trap generation. Minimum number of packets required for a trap to fire Enter the minimum number of packets that must pass through the device before an SNMP rate trap is sent. Symbol recommends using the default setting of 1000 as a minimum setting for the field. 4. Click Apply to save any changes to the SNMP RF Traps screen. Navigating away from the screen without clicking the Apply button results in all changes to the screen being lost. 5. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on SNMP RF Traps screen to the last saved configuration. 6. Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. 4.5 Configuring Network Time Protocol (NTP) Network Time Protocol (NTP) manages time and/or network clock synchronization in the access point-
managed network environment. NTP is a client/server implementation. The access point (an NTP client) periodically synchronizes its clock with a master clock (an NTP server). For example, the access point resets its clock to 07:04:59 upon reading a time of 07:04:59 from its designated NTP server. Time synchronization is recommended for the access points network operations. For sites using Kerberos authentication, time synchronization is required. Use the Date and Time Settings screen to enable NTP and specify the IP addresses and ports of available NTP servers. NOTE The current time is not set accurately when initially connecting to the access point. Until a server is defined to provide the access point the correct time, or the correct time is manually set, the access point displays 1970-01-01 00:00:00 as the default time. 4-32 AP-51xx Access Point Product Reference Guide To manage clock synchronization on the access point:
1. Select System Configuration - > Date/Time from the access point menu tree. 2. From within the Current Time field, click the Refresh button to update the time since the screen was displayed by the user. The Current Time field displays the current time based on the access point system clock. If NTP is disabled or if there are no servers available, the system time displays the access point uptime starting at 1970-01-01 00:00:00, with the time and date advancing. 3. Select the Set Date/Time button to display the Manual Date/Time Setting screen. This screen enables the user to manually enter the access points system time using a Year-Month-Day HH:MM:SS format. This option is disabled when the Enable NTP checkbox has been selected, and therefore should be viewed as a second means to define the access point system time. If using the Manual Date/Time Setting screen to define the access points system time, refer to the Time Zone field to select the time used to use as complimentary information to the information entered within the Manual Date/Time Setting screen. If using an NTP server to supply system time to the access point, configure the NTP Server Configuration field to define the server network address information required to acquire the access point network time. 5. 4. System Configuration 4-33 Enable NTP on access point Select the Enable NTP on access point checkbox to allow a connection between the access point and one or more specified NTP servers. A preferred, first alternate and second alternate NTP server cannot be defined unless this checkbox is selected. Disable this option (uncheck the checkbox) if Kerberos is not in use and time synchronization is not necessary. Preferred Time Server Specify the numerical (non DNS name) IP address and port of the First Alternate Time Server Second Alternate Time Server Synchronization Interval primary NTP server. The default port is 123. Optionally, specify the numerical (non DNS name) IP address and port of an alternative NTP server to use for time synchronization if the primary NTP server goes down. Optionally, specify the numerical (non DNS name) and port of yet another NTP server for the greatest assurance of uninterrupted time synchronization. Define an interval in minutes the access point uses to synchronize its system time with the NTP server. A synchronization interval value from 15 minutes to 65535 minutes can be specified. For implementations using Kerberos, a synchronization interval of 15 minutes (default interval) or sooner is recommended. 6. Click Apply to save any changes to the Date and time Settings screen. Navigating away from the screen without clicking the Apply button results in all changes to the screen being lost. 7. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on Date and Time Settings screen to the last saved configuration. 8. Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. 4-34 AP-51xx Access Point Product Reference Guide 4.6 Logging Configuration The access point provides the capability for periodically logging system events that prove useful in assessing the throughput and performance of the access point or troubleshooting problems on the access point managed Local Area Network (LAN). Use the Logging Configuration screen to set the desired logging level (standard syslog levels) and view or save the current access point system log. To configure event logging for the access point:
1. Select System Configuration - > Logging Configuration from the access point menu tree. 2. Configure the Log Options field to save event logs, set the log level and optionally port the access points log to an external server. System Configuration 4-35 View Log Logging Level Enable logging to an external syslog server Syslog server IP address Click View to save a log of events retained on the access point. The system displays a prompt requesting the administrator password before saving the log. After the password has been entered, click Get File to display a dialogue with buttons to Open or Save the log.txt file. Click Save and specify a location to save the log file. Use the WordPad application to view the saved log.txt file on a Microsoft Windows based computer. Do not view the log file using Notepad, as the Notepad application does not properly display the formatting of the access point log file. Log entries are not saved in the access point. While the AP is in operation, log data temporarily resides in memory. AP memory is completely cleared each time the AP reboots. Use the Logging Level drop-down menu to select the desired log level for tracking system events. Eight logging levels, (0 to 7) are available. Log Level 6: Info is the access point default log level. These are the standard UNIX/LINUX syslog levels.The levels are as follows:
0 - Emergency 1 - Alert 2 - Critical 3 - Errors 4 - Warning 5 - Notice 6 - Info 7 - Debug The access point can log events to an external syslog (system log) server. Select the Enable logging to an external syslog server checkbox to enable the server to listen for incoming syslog messages and decode the messages into a log for viewing. If the Enable logging to an external syslog server checkbox is selected, the numerical (non DNS name) IP address of an external syslog server is required in order to route the syslog events to that destination. 3. Click Apply to save any changes to the Logging Configuration screen. Navigating away from the screen without clicking the Apply button results in all changes to the screen being lost. 4-36 AP-51xx Access Point Product Reference Guide 4. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on the Logging Configuration screen to the last saved configuration. 5. Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. 4.7 Importing/Exporting Configurations All of the configuration settings for an access point can be obtained from another access point in the form of a text file. Additionally, all of the access points settings can be downloaded to another access point. Use the file-based configuration feature to speed up the setup process significantly at sites using multiple access points. Another benefit is the opportunity to save the current AP configuration before making significant changes or restoring the default configuration. All options on the access point are deleted and updated by the imported file. Therefore, the imported configuration is not a merge with the configuration of the target access point. The exported file can be edited with any document editor if necessary. The export function will always export the encrypted Admin User password. The import function will import the Admin Password only if the access point is set to factory default. If the access point is not configured to factory default settings, the Admin User password WILL NOT get imported.
!
CAUTION A single-radio model access point cannot import/export its configuration to a dual-radio model access point. In turn, a dual-radio model access point cannot import/export its configuration to a single-
radio access point. Use the Config Import/Export screen to configure an import or export operation for access point configuration settings. NOTE Use the System Settings screen as necessary to restore an access point default configuration. For more information on restoring configurations, see Configuring System Settings on page 4-2. System Configuration 4-37
!
CAUTION Symbol discourages importing a 1.0 baseline configuration file to a 1.1 version access point. Similarly, a 1.1 baseline configuration file should not be imported to a 1.0 version access point. Importing configuration files between different version access points results in broken configurations, since new features added to the 1.1 version access point cannot be supported in a 1.0 version access point. To create an importable/exportable access point configuration file:
1. Select System Configuration - > Config Import/Export from the access point menu tree. 2. Configure the FTP and TFTP Import/Export field to import/export configuration settings. Filename Server IP Specify the name of the configuration file to be written to the FTP or TFTP server. Enter the numerical (non DNS name) IP address of the destination FTP or TFTP server where the configuration file is imported or exported. Filepath (optional) Defines the optional path name used to import/export the target configuration file. FTP Select the FTP radio button if using an FTP server to import or export the configuration. 4-38 AP-51xx Access Point Product Reference Guide TFTP Username Password Import Configuration Export Configuration Select the TFTP radio button if using an FTP server to import or export the configuration.

CAUTION If errors occur when importing the configuration file, a parsing message displays defining the line number where the error occurred. The configuration is still imported, except for the error. Consequently, it is possible to import an invalid configuration. The user is required to fix the problem and repeat the import operation until an error-free import takes place. NOTE Symbol recommends importing configuration files using the CLI. If errors occur using the CLI, they display all at once and are easier to troubleshoot. The access point GUI displays errors one at a time, and troubleshooting can be a more time-consuming process. 5. Click Apply to save the filename and Server IP information. The Apply button does not execute the import or export operation, only saves the settings entered. 6. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on Config Import/Export screen to the last saved configuration. 7. Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. NOTE For a discussion on the implications of replacing an existing Symbol AP-4131 deployment with an AP-5131 or AP-5181, see Replacing an AP-4131 with an AP-5131 or AP-5181 on page B-18. 4.8 Updating Device Firmware Symbol periodically releases updated versions of the access point device firmware to the Symbol Web site. If the access point firmware version displayed on the System Settings page (see Configuring System Settings on page 4-2) is older than the version on the Web site, Symbol recommends updating the access point to the latest firmware version for full feature functionality. The access points update feature updates the access points firmware and configuration file automatically when the access point is reset or when the access point initiates a DHCP discovery. The firmware is automatically updated each time firmware versions are found to be different between the access point and the firmware file located on the DHCP/BootP server. If the System Configuration 4-41 configuration file is selected for automatic update, the configuration is automatically updated since the access point is unable to compare the differences between configuration files.
!
CAUTION If downgrading firmware from a 1.1 to a 1.0 version, the access point automatically reverts to 1.0 default settings, regardless of whether you are downloading the firmware manually or using the automatic download feature. The automatic feature allows the user to download the configuration file at the same time, but since the firmware reverts to 1.0 default settings, the configuration file is ignored. For detailed update scenarios involving both a Windows DHCP and a Linux BootP server configuration, see Configuring Automatic Updates using a DHCP or Linux BootP Server Configuration on page B-1.
!
CAUTION Loaded and signed CA certificates will be lost when changing the access points firmware version using either the GUI or CLI. After a certificate has been successfully loaded, export it to a secure location to ensure its availability after a firmware update. If a firmware update is required, use the Firmware Update screen to specify a filename and define a file location for updating the firmware. NOTE The firmware file must be available from an FTP or TFTP site to perform the update. CAUTION Make sure a copy of the access points configuration is exported before updating the firmware.
!
To conduct a firmware update on the access point:
1. Export the access point current configuration settings before updating the firmware to have the most recent settings available after the firmware is updated. Refer to Importing/Exporting Configurations on page 4-36 for instructions on exporting the access points current configuration to have it available after the firmware is updated. 2. Select System Configuration - > Firmware Update from the access point menu tree. 4-42 AP-51xx Access Point Product Reference Guide 3.

The update is conducted over the LAN or WAN port depending on which is the active port at the time the firmware update request is made. System Configuration 4-43 Enable Automatic Firmware Update Enable Automatic Configuration Update Select this checkbox to allow an automatic firmware update each time firmware versions are found to be different between the access point and the LAN or WAN interface. This option is used in conjunction with other DHCP options configured on a DHCP server. Symbol recommends selecting the Enable Automatic Configuration Update checkbox if auto-updating access point firmware, as backing up the access point configuration is always recommended before updating device firmware. If this function is disabled, the firmware update is required to be done manually. If this option is enabled, the access point initiates an update any time the access point reboots. If the files located on the DHCP server are different from the existing files on the access point, the files are updated. The default setting is enabled on the WAN port. Select this checkbox to allow an automatic configuration file update each time the configuration file versions are found to be different between the access point and the LAN or WAN interface. If this function is disabled, the configuration file update is required to be done manually. If this function is disabled, the firmware update is required to be done manually. If this option is enabled, the access point initiates an update any time the access point reboots. If the files located on the DHCP server are different from the existing files on the access point, the files are updated. The default setting is enabled on the WAN port. Configure the Update Firmware field as required to set a filename and target firmware file upload location for manual firmware updates. 4. Specify the name of the target firmware file within the Filename field. 5. If the target firmware file resides within a directory, specify a complete path for the file within the Filepath(optional) field. Enter an IP address for the FTP or TFTP server used for the update. Only numerical IP address names are supported, no DNS can be used. 6. 7. Select either the FTP or TFTP button to define whether the firmware file resides on a FTP or TFTP server. 8.

!
CAUTION Prior to upgrading/downgrading the access points configuration, ensure the access points current configuration has been exported to a secure location. Having the configuration available is recommended in case errors occur in the upgrade/downgrade process.
When downgrading from 1.1 to 1.0, the access point is configured to default values.
After a downgrade from 1.1.0.0-XX to 1.0.0.0-XX, WLANs mapped to LAN2 would still be usable, but now only available on LAN1. Once upgraded back to 1.1.0.0-XX, those WLANs previously available on LAN2 would still be mapped to LAN2.
If downgraded to the 1.0.0.0-XX baseline, and a restore factory defaults function is performed, only 1.0.0.0-XX default values are restored to their factory default values. The feature set unique to 1.1.0.0-XX can only be restored to factory default when the access point is running 1.1.0.0-XX firmware.
Export either a CA or Self Certificate to a safe and secure location before upgrading or downgrading your access point firmware. If the certificate is not saved, it will be discarded and not available to the user after the upgrade or downgrade. If discarded, a new certificate request would be required.

See the following sections for more information on access point network management:
Configuring the LAN Interface
Configuring WAN Settings
Enabling Wireless LANs (WLANs)
Configuring Router Settings 5.1 Configuring the LAN Interface The access point has one physical LAN port supporting two unique LAN interfaces. The access point LAN port has its own MAC address. The LAN port MAC address is always the value of the access point WAN port MAC address plus 1. The LAN and WAN port MAC addresses can be located within the LAN and WAN Stats screens. For information on locating the access point MAC addresses, see Viewing WAN Statistics on page 7-2 and Viewing LAN Statistics on page 7-6. 5-2 AP-51xx Access Point Product Reference Guide Use the LAN Configuration screen to enable one (or both) of the access points LAN interfaces, assign them names, define which LAN is currently active on the access point Ethernet port and assign a timeout value to disable the LAN connection if no data traffic is detected within a defined interval. To configure the access point LAN interface:
1. Select Network Configuration -> LAN from the access point menu tree. 2. Configure the LAN Settings field to enable the access point LAN1 and/or LAN2 interface, assign a timeout value, enable 802.1q trunking, configure WLAN mapping and enable 802.1x port authentication. Enable LAN Name Select the LAN1 and/or LAN2 checkbox to allow the forwarding of data traffic over the specified LAN connection. The LAN1 connection is enabled by default, but both LAN interfaces can be enabled simultaneously. Use the LAN Name field to modify the existing name of LAN1 and LAN2. LAN1 and LAN2 are the default names assigned to the LANs until modified by the user. Network Management 5-3 Ethernet Port Enable 802.1q Trunking VLAN Name WLAN Mapping The Ethernet Port radio buttons allow you to select one of the two available LANs as the LAN actively transmitting over the access points LAN port. Both LANs can be active at any given time, but only one can transmit over the access point physical LAN connection, thus the selected LAN has priority. Select the Enable 802.1q Trunking checkbox to enable the LAN to conduct VLAN tagging. If selected, click the WLAN Mapping button to configure mappings between individual WLANs and LANs. If enabled, the access point is required to be connected to a trunked port. Click the VLAN Name button to launch the VLAN Name screen to create VLANs and assign them VLAN IDs. For more information, see Configuring VLAN Support on page 5-4. Click the WLAN Mapping button to launch the VLAN Configuration screen to map existing WLANs to one of the two LANs and define the WLANs VLAN membership (up to 16 mappings are possible per access point). For more information, see Configuring VLAN Support on page 5-4. Ethernet Port Timeout Use the Ethernet Port Timeout drop-down menu to define how the access point interprets inactivity for the LAN assigned to the Ethernet port. When Enabled is selected, the access point uses the value defined in the Sec. box (default is 30 seconds). Selecting Disabled allows the LAN selected to use the Ethernet port for an indefinite timeout period. The access point only supports 802.1x authentication over its LAN port. The access point behaves as an 802.1x supplicant to authenticate to a server on the network. If using 802.1x authentication, enter the authentication server user name and password. The default password is symbol. For information on enabling and configuring authentication schemes on the access point, see Enabling Authentication and Encryption Schemes on page 6-5. 802.1x Port Authentication 3.

A prompt displays confirming the logout before the applet is closed. 5.1.1 Configuring VLAN Support A Virtual Local Area Network (VLAN) is a means to electronically separate data on the same access point from a single broadcast domain into separate broadcast domains. The access point can group devices on one or more WLANs so that they can communicate as if they were attached to the same wire, when in fact they are located on a different LAN segment. Because VLANs are based on logical instead of physical connections, they are extremely flexible. By using a VLAN, you can group by logical function instead of physical location. A maximum of 16 VLANs can be supported on the access point (regardless of the access point being single or dual-radio model). An administrator can map 16 WLANs to 16 VLANs and enable or disable dynamic VLAN assignment. VLANs enable organizations to share network resources in various network segments within large areas (airports, shopping malls, etc.). A VLAN is a group of clients with a common set of requirements independent of their physical location. VLANs have the same attributes as physical LANs, but they enable system administrators to group MUs even when they are not members of the same network segment. NOTE A WLAN supporting a mesh network does not need to be assigned to a particular VLAN, as all the traffic proliferating the mesh network is already trunked. However, if MUs are to be connected to the Mesh WLAN, the WLAN will need to be tied to a VLAN. The access point assignment of VLANs can be implemented using Static or Dynamic assignments
(often referred to as memberships) for individual WLANs. Both methods have their advantages and disadvantages. Static VLAN membership is perhaps the most widely used method because of the relatively small administration overhead and security it provides. With Static VLANs, you manually assign individual WLANs to individual VLANs. Although static VLANs are the most common form of VLAN assignments, dynamic VLAN assignment is possible per WLAN. Configuring dynamic VLANs entail the access point sending a DHCP request for device information (such as an IP address). Additional information (such as device MAC address information) is sent to the access point. The access point sends this MAC address to a host housing a copy of the Dynamic VLAN database. This database houses the records of MAC addresses and VLAN assignments. The VLAN database looks up the MAC to determine what VLAN is assigned to it. If it is not in the database, it simply uses a default VLAN assignment. The VLAN assignment is sent Network Management 5-5 to the access point. The access point then maps the target WLAN for the assigned VLAN and traffic passes normally, allowing for the completion of the DHCP request and further traffic. To create new VLANs or edit the properties of an existing VLAN:
1. Select Network Configuration -> LAN from the access point menu tree. 2. Ensure the Enable 802.1q Trunking button is selected from within the LAN Setting field. Trunk links are required to pass VLAN information between destinations. A trunk port is by default a member of all the VLANs existing on the access point and carry traffic for all those VLANs. Trunking is a function that must be enabled on both sides of a link. 3. Select the VLAN Name button. The VLAN name screen displays. The first time the screen is launched a default VLAN name of 1 and a default VLAN ID of 1 display. The VLAN name is auto-generated once the user assigns a VLAN ID. However, the user has the option of re-assigning a name to the VLAN using New VLAN and Edit VLAN screens. 5-6 AP-51xx Access Point Product Reference Guide To create a new VLAN, click the Create button, to edit the properties of an existing VLAN, click the Edit button. 4. Assign a unique VLAN ID (from 1 to 4095) to each VLAN added or modified. The VLAN ID associates a frame with a specific VLAN and provides the information the access point needs to process the frame across the network. Therefore, it may be practical to assign a name to a VLAN representative or the area or type of network traffic it represents. A business may have offices in different locations and want to extend an internal LAN between the locations. An access point managed infrastructure could provide this connectivity, but it requires VLAN numbering be managed carefully to avoid conflicts between two VLANs with the same ID. 5. Define a 32 ASCII character maximum VLAN Name. Enter a unique name that identifies members of the VLAN. Symbol recommends selecting the name carefully, as the VLAN name should signify a group of clients with a common set of requirements independent of their physical location. 6. Click Apply to save the changes to the new or modified VLAN. 7. From the LAN Configuration screen, click the WLAN Mapping button. The Mapping Configuration screen displays. Network Management 5-7 8. Enter a Management VLAN Tag for LAN1 and LAN2. The Management VLAN uses a default tag value of 1. The Management VLAN is used to distinguish VLAN traffic flows for the LAN. The trunk port marks the frames with special tags as they pass between the access point and its destination, these tags help distinguish data traffic. Authentication servers (such as Radius and Kerberos) must be on the same Management VLAN. Additionally, DHCP and BOOTP servers must be on the same Management VLAN as well. 9. Define a Native VLAN Tag for LAN1 and LAN2. A trunk port configured with 802.1Q tagging can receive both tagged and untagged traffic. By default, the access point forwards untagged traffic with the native VLAN configured for the port. The Native VLAN is VLAN 1 by default. Symbol suggests leaving the Native VLAN set to 1 as other layer 2 devices also have their Native VLAN set to 1. 10. Use the LAN drop-down menu to map one of the two LANs to the WLAN listed to the left. With this assignment, the WLAN uses this assigned LAN interface. 11. Select the Dynamic checkboxes (under the Mode column) to configure the VLAN mapping as a dynamic VLAN. Using Dynamic VLAN assignments, a VMPS (VLAN Management Policy Server) dynamically assigns VLAN ports. The access point uses a separate server as a VMPS server. When a 5-8 AP-51xx Access Point Product Reference Guide frame arrives on the access point, it queries the VMPS for the VLAN assignment based on the source MAC address of the arriving frame. If statically mapping VLANs, leave the Dynamic checkbox specific to the target WLAN and its intended VLAN unselected. The administrator is then required to configure VLAN memberships manually. The Dynamic checkbox is enabled only when a WLAN is having EAP security configured. Otherwise, the checkbox is disabled. 12. Use the VLAN drop-down menu to select the name of the target VLAN to map to the WLAN listed on the left-hand side of the screen. Symbol recommends mapping VLANs strategically in order to keep VLANs tied to the discipline they most closely match. For example, If WLAN1 is comprised of MUs supporting the sales area, then WLAN1 should be mapped to sales if a sales VLAN has been already been created. 13. Click Apply to return to the VLAN Name screen. Click OK to return to the LAN screen. Once at the LAN screen, click Apply to re-apply your changes. 5.1.2 Configuring LAN1 and LAN2 Settings Both LAN1 and LAN2 have separate sub-screens to configure the DHCP settings used by the LAN1 and LAN2 interfaces. Within each LAN screen is a button to access a sub-screen to configure advanced DHCP settings for that LAN. For more information, see Configuring Advanced DHCP Server Settings on page 5-11. Additionally, LAN1 and LAN2 each have separate Type Filter submenu items used to prevent specific (an potentially unneccesary) frames from being processed, for more information, see Setting the Type Filter Configuration on page 5-13. To configure unique settings for either LAN1 or LAN2:
1. Select Network Configuration -> LAN -> LAN1 (or LAN2) from the access point menu tree. Network Management 5-9 2. Configure the DHCP Configuration field to define the DHCP settings used for the LAN. NOTE Symbol recommends the WAN and LAN ports should not both be configured as DHCP clients. This interface is a DHCP Client This interface is a BOOTP Client Select this button to enable DHCP to set access point network address information via this LAN1 or LAN2 connection. This is recommended if the access point resides within a large corporate network or the Internet Service Provider (ISP) uses DHCP. DHCP is a protocol that includes mechanisms for IP address allocation and delivery of host-specific configuration parameters from a DHCP server to a host. If DHCP Client is selected, the first DHCP or BOOTP server to respond sets the IP address and network address values since DHCP and BOOTP are interoperable. Select this button to enable BOOTP to set access point network address information via this LAN1 or LAN2 connection. When selected, only BOOTP responses are accepted by the access point. If both DHCP and BOOTP services are required, do not select BOOTP Client. 5-10 AP-51xx Access Point Product Reference Guide This interface uses static IP Address This interface is a DHCP Server Address Assignment Range Advanced DHCP Server IP Address Network Mask Default Gateway Domain Name Primary DNS Server Secondary DNS Server Select the This interface uses static IP Address button, and manually enter static network address information in the areas provided. The access point can be configured to function as a DHCP server over the LAN1 or LAN2 connection. Select the This interface is a DHCP Server button and manually enter static network address information in the areas provided. Use the address assignment parameter to specify a range of numerical (non DNS name) IP addresses reserved for mapping client MAC addresses to IP addresses. If a manually (static) mapped IP address is within the IP address range specified, that IP address could still be assigned to another client. To avoid this, ensure all statically mapped IP addresses are outside of the IP address range assigned to the DHCP server. Click the Advanced DHCP Server button to display a screen used for generating a list of static MAC to IP address mappings for reserved clients. A separate screen exists for each of the LANs. For more information, see Configuring Advanced DHCP Server Settings on page 5-11. The network-assigned numerical (non DNS name) IP address of the access point. The first two sets of numbers specify the network domain, the next set specifies the subset of hosts within a larger network. These values help divide a network into subnetworks and simplify routing and data transmission. The subnet mask defines the size of the subnet. The Default Gateway parameter defines the numerical (non DNS name) IP address of a router the access point uses on the Ethernet as its default gateway. Enter the name assigned to the primary DNS server. Enter the Primary DNS numerical (non DNS name) IP address. Symbol recommends entering the numerical IP address of an additional DNS server (if available), used if the primary DNS server goes down. A maximum of two DNS servers can be used. Network Management 5-11 WINS Server Mesh STP Configuration Enter the numerical (non DNS name) IP address of the WINS server. WINS is a Microsoft NetBIOS name server. Using a WINS server eliminates the broadcasts needed to resolve computer names to IP addresses by providing a cache or database of translations. Click the Mesh STP Configuration button to define bridge settings for this specific LAN. Each of the access points two LANs can have a separate mesh configuration. As the Spanning Tree Protocol (STP) mentions, each mesh network maintains hello, forward delay and max age timers. These settings can be used as is using the current default settings, or be modified. However, if these settings are modified, they need to be configured for the LAN connecting to the mesh network WLAN. For information on mesh networking capabilities, see Configuring Mesh Networking Support on page 9-5. If new to mesh networking and in need of an overview, see Mesh Networking Overview on page 9-1. 3. Click Apply to save any changes to the LAN1 or LAN2 screen.

Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. 5.1.2.1 Configuring Advanced DHCP Server Settings Use the Advanced DHCP Server screen to specify (reserve) static (or fixed) IP addresses for specific devices. Every wireless, 802.11x-standard device has a unique Media Access Control (MAC) address. This address is the device's hard-coded hardware number (shown on the bottom or back). An example of a MAC address is 00:A0:F8:45:9B:07. The DHCP server can grant an IP address for as long as it remains in active use. The lease time is the number of seconds that an IP address is reserved for re-connection after its last use. Using very short leases, DHCP can dynamically reconfigure networks in which there are more computers than available IP addresses. This is useful, for example, in education and customer environments where MU users change frequently. Use longer leases if there are fewer users. To generate a list of client MAC address to IP address mappings for the access point:
5-12 AP-51xx Access Point Product Reference Guide 1. Select Network Configuration -> LAN -> LAN1 (or LAN2) from the access point menu tree. 2. Click the Advanced DHCP Server button from within the LAN1 or LAN2 screen. 3. Specify a lease period in seconds for available IP addresses using the DHCP Lease Time
(Seconds) parameter. An IP address is reserved for re-connection for the length of time you specify. The default interval is 86400 seconds. 4. Click the Add button to create a new table entry within the Reserved Clients field. If a statically mapped IP address is within the IP address range in use by the DHCP server, that IP address may still be assigned to another client. To avoid this, ensure all statically mapped IP addresses are outside of the IP address range assigned to the DHCP server. If multiple entries exist within the Reserved Clients field, use the scroll bar to the right of the window to navigate. 5. Click the Del (delete) button to remove a selected table entry. 6. Click OK to return to the LAN1 or LAN2 page, where the updated settings within the Advanced DHCP Server screen can be saved by clicking the Apply button. 7. Click Cancel to undo any changes made. Undo Changes reverts the settings displayed to the last saved configuration. Network Management 5-13 5.1.2.2 Setting the Type Filter Configuration Each access point LAN (either LAN1 or LAN2) can keep a list of frame types that it forwards or discards. The Type Filtering feature prevents specific (a potentially unneccesary) frames from being processed by the access point in order to improve throughput. These include certain broadcast frames from devices that consume bandwidth, but are unnecessary to access point operations. Use the Ethernet Type Filter Configuration screen to build a list of filter types and configure them as either allowed or denied for use with the this particular LAN. To configure type filtering on the access point:
1. Select Network Configuration-> LAN -> LAN1 (or LAN2)-> Type Filter from the access point menu tree. The Ethernet Type Filter Configuration screen displays for the LAN. No Ethernet types are displayed (by default) when the screen is first launched. 2. Use the all ethernet types, except drop-down menu to designate whether the Ethernet 3. Types defined for the LAN are allowed or denied for use by the access point. To add an Ethernet type, click the Add button. The Add Ethernet Type screen displays. Use this screen to add one type filter option at a time, for a list of up to 16 entries. 5-14 AP-51xx Access Point Product Reference Guide Packet types supported for the type filtering function include 16-bit DIX Ethernet types as well as Symbol proprietary types. Select an Ethernet type from the drop down menu, or enter the Ethernet types hexadecimal value. Consult with your System Administrator if unsure of the implication of adding or omitting a type from the list for either LAN1 or LAN2. To optionally delete a type filtering selection from the list, highlight the packet type and click the Delete button. 4. 5. Click Apply to save any changes to the LAN1 or LAN2 Ethernet Type Filter Configuration screen. Navigating away from the screen without clicking Apply results in all changes to the screens being lost. 6. Click Cancel to securely exit the LAN1 or LAN2 Ethernet Type Filter Configuration screen without saving your changes. 7. Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. 5.2 Configuring WAN Settings A Wide Area Network (WAN) is a widely dispersed telecommunications network. The access point includes one WAN port. The access point WAN port has its own MAC address. In a corporate environment, the WAN port might connect to a larger corporate network. For a small business, the WAN port might connect to a DSL or cable modem to access the Internet. Use the WAN screen to set the WAN IP configuration and Point-to-Point Protocol over Ethernet
(PPPoE) parameters. To configure WAN settings for the access point:
1. Select Network Configuration -> WAN from the access point menu tree. Network Management 5-15 2. Refer to the WAN IP Configuration field to enable the WAN interface, and set network address information for the WAN connection. NOTE Symbol recommends that the WAN and LAN ports should not both be configured as DHCP clients. Enable WAN Interface Select the Enable WAN Interface checkbox to enable a connection between the access point and a larger network or outside world through the WAN port. Disable this option to effectively isolate the access points WAN. No connections to a larger network or the Internet are possible. MUs cannot communicate beyond the LAN. 5-16 AP-51xx Access Point Product Reference Guide This interface is a DHCP Client IP Address Subnet Mask Default Gateway Primary DNS Server This checkbox enables DHCP for the access point WAN connection. This is useful, if the larger corporate network or Internet Service Provider (ISP) uses DHCP. DHCP is a protocol that includes mechanisms for IP address allocation and delivery of host-specific configuration parameters from a DHCP server to a host. Some of these parameters are IP address, network mask, and gateway. If DHCP client mode is enabled, the other WAN IP configuration parameters are grayed out. Specify a numerical (non DNS name) IP address for the access points WAN connection. This address defines the AP's presence on a larger network or on the Internet. Obtain a static (dedicated) IP address from the ISP or network administrator. An IP address uses a series of four numbers expressed in dot notation, for example, 190.188.12.1. Specify a subnet mask for the access points WAN connection. This number is available from the ISP for a DSL or cable-modem connection, or from an administrator if the access point connects to a larger network. A subnet mask uses a series of four numbers expressed in dot notation (similar to an IP address). For example, 255.255.255.0 is a valid subnet mask. Specify the gateway address for the access points WAN connection. The ISP or a network administrator provides this address. Specify the address of a primary Domain Name System (DNS) server. The ISP or a network administrator provides this address. A DNS server translates a domain name (for example, www.symboltech.com) into an IP address that networks can use. Secondary DNS Server Specify the address of a secondary DNS server if one is used. A secondary address is recommended if the primary DNS server goes down. Network Management 5-17 More IP Addresses Refresh Click the More IP Addresses button to specify additional static IP addresses for the access point. Additional IP addresses are required when users within the WAN need dedicated IP addresses, or when servers need to be accessed (addressed) by the outside world. The More IP Addresses screen allows the administrator to enter up to seven additional WAN IP addresses for the access point WAN. Only numeric, non-DNS names can be used. If PPP over Ethernet is enabled from within the WAN screen, the VPN WAN IP Configuration portion of the More IP Addresses screen is enabled. Enter the IP address and subnet mask used to provide the PPPoE connection over the access points WAN port. Ensure the IP address is a numerical (non DNS) name. Click the Refresh button to update the network address information displayed within the WAN IP Configuration field. 3. Configure the PPP over Ethernet field to enable high speed dial-up connections to the access point WAN port. Enable Username Password PPPoE State Use the checkbox to enable Point-to-Point over Ethernet (PPPoE) for a high-speed connection that supports this protocol. Most DSL providers are currently using or deploying this protocol. PPPoE is a data-link protocol for dialup connections. PPPoE allows a host PC to use a broadband modem (DSL) for access to high-
speed data networks. Specify a username entered when connecting to the ISP. When the Internet session begins, the ISP authenticates the username. Specify a password entered when connecting to the ISP. When the Internet session starts, the ISP authenticates the password. Displays the current connection state of the PPPoE client. When a PPPoE connection is established, the status displays Connected. When no PPPoE connection is active, the status displays Disconnected. 5-18 AP-51xx Access Point Product Reference Guide Keep-Alive Idle Time (seconds) Authentication Type Select the Keep-Alive checkbox to maintain the access point WAN connection indefinitely (no timeout interval). Some ISPs terminate inactive connections. Enabling Keep-Alive keeps the access point WAN connection active, even when there is no traffic. If the ISP drops the connection after an idle period, the access point automatically re-establishes the connection to the ISP. Enabling Keep-Alive mode disables (grays out) the Idle Time field. Specify an idle time in seconds to limit how long the access points WAN connection remains active after outbound and inbound traffic is not detected. The Idle Time field is grayed out if Keep-Alive is enabled. Use the Authentication Type menu to specify the authentication protocol(s) for the WAN connection. Choices include None, PAP or CHAP, PAP, or CHAP. Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP) are competing identify-verification methods. PAP sends a username and password over a network to a server that compares the username and password to a table of authorized users. If the username and password are matched in the table, server access is authorized. WatchGuard products do not support the PAP protocol because the username and password are sent as clear text that a hacker can read. CHAP uses secret information and mathematical algorithms to send a derived numeric value for login. The login server knows the secret information and performs the same mathematical operations to derive a numeric value. If the results match, server access is authorized. After login, one of the numbers in the mathematical operation is changed to secure the connection. This prevents any intruder from trying to copy a valid authentication session and replaying it later to log in. 4. Click Apply to save any changes to the WAN screen. Navigating away from the screen without clicking the Apply button results in all changes to the screen being lost. 5. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on the WAN screen to the last saved configuration. Network Management 5-19 6. Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. 5.2.1 Configuring Network Address Translation (NAT) Settings Network Address Translation (NAT) converts an IP address in one network to a different IP address or set of IP addresses in another network. The access point router maps its local (inside) network addresses to WAN (outside) IP addresses, and translates the WAN IP addresses on incoming packets to local IP addresses. NAT is useful because it allows the authentication of incoming and outgoing requests, and minimizes the number of WAN IP addresses needed when a range of local IP addresses is mapped to each WAN IP address. NAT can be applied in one of two ways:
One-to-one mapping with a private side IP address The private side IP address can belong to any of the private side subnets.
One-to-many mapping with a configurable range of private side IP addresses Ranges can be specified from each of the private side subnets. Use the NAT screen to configure IP address mappings. To configure IP address mappings for the access point:
1. Select Network Configuration -> WAN -> NAT from the access point menu tree. 5-20 AP-51xx Access Point Product Reference Guide 2. Configure the Address Mappings field to generate a WAN IP address, define the NAT type and set outbound/inbound NAT mappings. WAN IP Address NAT Type The WAN IP addresses on the NAT screen are dynamically generated from address settings applied on the WAN screen. Specify the NAT Type as 1 to 1 to map a WAN IP address to a single host (local) IP address. 1 to 1 mapping is useful when users need dedicated addresses, and for public-facing servers connected to the access point. Set the NAT Type as 1 to Many to map a WAN IP address to multiple local IP addresses. This displays the 1 to Many Mappings button in the adjacent Outbound Mappings field. This button displays a screen for mapping the LAN IP addresses that are associated with each subnet. Define the NAT Type as none when routable IP addresses are used on the internal network. Outbound Mappings When 1 to 1 NAT is selected, a single IP address can be entered in the Outbound Mappings area. This address provides a 1 to 1 mapping of the WAN IP address to the specified IP address. When 1 to Many is selected as the NAT Type, the Outbound Mappings area displays a 1 to Many Mappings button. Click the button to select the LAN1 or LAN2 IP address used to set the outbound IP address or select none to exclude the IP address. Inbound Mappings Port Forwarding If none is selected as the NAT Type, The Outbound Mappings area is blank. When 1 to 1 or 1 to Many is selected, the Inbound Mappings option displays a Port Forwarding button. Click the Port Forwarding button to display a screen of port forwarding parameters for inbound traffic from the associated WAN IP address. for information on configuring port forwarding, see Configuring Port Forwarding on page 5-21. 3. Click Apply to save any changes to the NAT screen. Navigating away from the screen without clicking the Apply button results in all changes to the screens being lost. 4. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on the NAT screen to the last saved configuration. Network Management 5-21 5.

A WLAN does not require lining up devices for line-of-sight transmission, and are thus, desirable. Within the WLAN, roaming users can be handed off from one access point to another like a cellular phone system. WLANs can therefore be configured around the needs of specific groups of users, even when they are not in physical proximity. Use the access points Wireless Configuration screen to create new WLANs, edit the properties of existing WLANs or delete a WLAN to create space for a new WLAN. Sixteen WLANs are available on the access point (regardless of single or dual-radio model). Network Management 5-23 To configure WLANs on the access point:

The name should be logical representation of WLAN coverage area (engineering, marketing etc.). The maximum number of characters that can be used for the name is 31. Use the Available On checkboxes to define whether the WLAN you are creating or editing is available to clients on either the 802.11a or 802.11b/g radio (or both radios). The Available On checkbox should only be selected for a mesh WLAN if this target access point is to be configured as a base bridge or repeater (base and client bridge) on the radio. If the radio for the WLAN is to be defined as a client bridge only, the Available On checkbox should not be selected. For more information on defining a WLAN for mesh support, see Configuring a WLAN for Mesh Networking Support on page 9-7. Use the Max MUs field to define the number of MUs permitted to interoperate within the new or revised WLAN. The maximum (and default) is 127. However, each access point can only support a maximum 127 MUs spanned across its 16 available WLANs. If you intend to define numerous WLANs, ensure each is using a portion of the 127 available MUs and the sum of the supported MUs across all WLANs does not exceed 127. Select the Enable Client Bridge Backhaul checkbox to make the WLAN available in the WLAN drop-down menu within the Radio Configuration screen. This checkbox can be ignored for WLANs not supporting mesh networking, to purposely exclude them from the list of WLANs available in the Radio Configuration page selected specifically for mesh networking support. Only WLANs defined for mesh networking support should have this checkbox selected. Network Management 5-27 Enable Hotspot Select the Enable Hotspot checkbox to allow this WLAN (whether it be a new or existing WLAN) to be configured for hotspot support. Clicking the Configure Hotspot button launches a screen wherein the parameters of the hotspot can be defined. For information on configuring a target WLAN for hotspot support, see Configuring WLAN Hotspot Support on page 5-39. For an overview of what a hotspot is and what it can provide your wireless network, see Hotspot Support on page 1-4.
!
CAUTION A WLAN cannot be enabled for both mesh and hotspot support at the same time. Only one of these two options can be enabled at one time, as the GUI and CLI will prevent both from being enabled. NOTE If 802.11a is selected as the radio used for the WLAN, the WLAN cannot use a Kerberos supported security policy. 4. Configure the Security field as required to set the data protection requirements for the WLAN. NOTE A WLAN configured to support Mesh should not have a Kerberos or 802.1x EAP security policy defined for it, as these two authentication schemes are not supported within a Mesh network. Security Policy MU Access Control Use the scroll down Security Policies menu to select the security scheme best suited for the new or revised WLAN. Click the Create button to jump to the New Security Policy screen where a new policy can be created to suit the needs of the WLAN. For more information, see Configuring WLAN Security Policies on page 5-29. Select an ACL policy suiting the WLANs MU introperability requirements from the drop-down menu. If the existing ACL policies do not satisfy the requirements of the WLAN, a new ACL policy can be created by pressing the Create button. For more information, see Configuring a WLAN Access Control List (ACL) on page 5-30. Kerberos User Name Displays the read-only Kerboros User Name used to associate the wireless client. This value is the ESSID of the access point. 5-28 AP-51xx Access Point Product Reference Guide Kerberos Password Enter a Kerberos password if Kerberos has been selected as the security scheme from within the Security Policies field. The field is grayed out if Kerberos has not been selected for the WLAN. For information on configuring Kerberos, see Configuring Kerberos Authentication on page 6-9. 5. Configure the Advanced field as required to set MU interoperability permissions, secure beacon transmissions, broadcast ESSID acceptance and Quality of Service (QoS) policies. Disallow MU to MU Communication Use Secure Beacon Accept Broadcast ESSID Quality of Service Policy The MU-MU Disallow feature prohibits MUs from communicating with each other even if they are on different WLANs, assuming one of the WLANs is configured to disallow MU-MU communication. Therefore, if an MUs WLAN is configured for MU-MU disallow, it will not be able to communicate with any other MUs connected to this access point. Select the Use Secure Beacon checkbox to not transmit the access points ESSID. If a hacker tries to find an ESSID via an MU, the ESSID does not display since the ESSID is not in the beacon. Symbol recommends keeping the option enabled to reduce the likelihood of hacking into the WLAN. Select the Accept Broadcast ESSID checkbox to associate an MU that has a blank ESSID (regardless of which ESSID the access point is currently using). Sites with heightened security requirements may want to leave the checkbox unselected and configure each MU with an ESSID. The default is unselected, thus not allowing the acceptance of broadcast ESSIDs. If QoS policies are undefined (none), select the Create button to launch the New QoS Policy screen. Use this screen to create a QoS policy, wherein data traffic for the new or revised WLAN can be prioritized to best suit the MU transmissions within that WLAN. For more information, see Setting the WLAN Quality of Service (QoS) Policy on page 5-33.
!
CAUTION When using the access points hotspot functionality, ensure MUs are re-authenticated when changes are made to the characteristics of a hotspot enabled WLAN, as MUs within the WLAN will be dropped from device association. Network Management 5-29 6. Click Apply to save any changes to the WLAN screen. Navigating away from the screen without clicking Apply results in all changes to the screens being lost. 7. Click Cancel to securely exit the New WLAN or Edit WLAN screen and return to the Wireless Configuration screen. 5.3.1.1 Configuring WLAN Security Policies As WLANs are being defined for an access point, a security policy can be created or an existing policy edited (using the Create or Edit buttons within the Security Configuration screen) to best serve the security requirements of the WLAN. Once new policies are defined, they are available within the New WLAN or Edit WLAN screens and can be mapped to any WLAN. A single security policy can be used by more than one WLAN if its logical to do so. For example, there may be two or more WLANs within close proximity of each other requiring the same data protection scheme. To create a new security policy or modify an existing policy:
1. Select Network Configuration -> Wireless -> Security from the access point menu tree. The Security Configuration screen appears with existing policies and their attributes displayed. NOTE When the access point is first launched, a single security policy (default) is available and mapped to WLAN 1. It is anticipated numerous additional security policies will be created as the list of WLANs grows. Configuring a WLAN security scheme with a discussion of all the authentication and encryption options available is beyond the scope of this chapter. See Chapter 6, Configuring Access Point Security on page 6-1 for more details on configuring access point security. For detailed information on the authentication and encryption options available to the access point and how to configure them, see to Configuring Security Options on page 6-2 and locate the section that describes your intended security scheme. 5-30 AP-51xx Access Point Product Reference Guide 2. Click Logout to exit the Security Configuration screen. 5.3.1.2 Configuring a WLAN Access Control List (ACL) An Access Control Lists (ACL) affords a system administrator the ability to grant or restrict MU access by specifying a MU MAC address or range of MAC addresses to either include or exclude from access point connectivity. Use the Mobile Unit Access Control List Configuration screen to create new ACL policies (using the New MU ACL Policy sub-screen) or edit existing policies (using the Edit MU ACL Policy sub-screen). Once new policies are defined, they are available for use within the New WLAN or Edit WLAN screens to assign to specific WLANs based on MU interoperability requirements. Symbol recommends using the New MU ACL Policy or Edit MU ACL Policy screens strategically to name and configure ACL policies meeting the requirements of the particular WLANs they may map to. However, be careful not to name policies after specific WLANs, as individual ACL policies can be used by more than one WLAN. For detailed information on assigning ACL policies to specific WLANs, see Creating/Editing Individual WLANs on page 5-24. To create or edit ACL policies for WLANs:
1. Select Network Configuration -> Wireless -> MU ACL from the access point menu tree. The Mobile Unit Access Control List Configuration screen displays with existing ACL policies and their current WLAN (if mapped to a WLAN). Network Management 5-31 NOTE When the access point is first launched, a single ACL policy (default) is available and mapped to WLAN 1. It is anticipated numerous additional ACL policies will be created as the list of WLANs grows. 2. Click the Create button to configure a new ACL policy, or select a policy and click the Edit button to modify an existing ACL policy. The access point supports a maximum of 16 MU ACL policies. 5-32 AP-51xx Access Point Product Reference Guide Either the New MU ACL Policy or Edit MU ACL Policy screens display. 3. Assign a name to the new or edited ACL policy that represents an inclusion or exclusion policy specific to a particular type of MU traffic you may want to use with a single or group of WLANs. More than one WLAN can use the same ACL policy. 4. Configure the parameters within the Mobile Unit Access Control List field to allow or deny MU access to the access point. The MU adoption list identifies MUs by their MAC address. The MAC address is the MU's unique Media Access Control number printed on the device (for example, 00:09:5B:45:9B:07) by the manufacturer. A maximum of 200 MU MAC addresses can be added to the New/Edit MU ACL Policy screen. Access for the listed Mobile Units Add Delete Use the drop-down list to select Allow or Deny. This rule applies to the MUs listed in the table. For example, if the adoption rule is to Allow, access is granted for all MUs except those listed in the table. Click the Add button to create a new entry using only the Start MAC column to specify a MAC address, or uses both the Start MAC and End MAC columns to specify a range of MAC addresses.

A prompt displays confirming the logout before the applet is closed. 5.3.1.3 Setting the WLAN Quality of Service (QoS) Policy The access point can keep a list of QoS policies that can be used from the New WLAN or Edit WLAN screens to map to individual WLANs. Use the Quality of Service Configuration screen to configure WMM policies that can improve the user experience for audio, video and voice applications by shortening the time between packet transmissions for higher priority (multimedia) traffic. Use the Quality of Service Configuration screen to define the QoS policies for advanced network traffic management and multimedia applications support. If the existing QoS policies are insufficient, a new policy can be created or an existing policy can be modified using the New QoS Policy or Edit QoS Policy screens. Once new policies are defined, they are available for use within the New WLAN or Edit WLAN screens to assign to specific WLANs based on MU interoperability requirements. Symbol recommends using the New QoS Policy and Edit QoS Policy screens strategically to name and configure QoS policies meeting the requirements of the particular WLANs they may map to. However, be careful not to name policies after specific WLANs, as individual QoS policies can be used by more than one WLAN. For detailed information on assigning QoS policies to specific WLANs, see Creating/Editing Individual WLANs on page 5-24. To configure QoS policies:
1. Select Network Configuration -> Wireless -> QoS from the access point menu tree. The Quality of Service Configuration screen displays with existing QoS policies and their current WLAN (if mapped to a WLAN). NOTE When the access point is first launched, a single QoS policy (default) is available and mapped to WLAN 1. It is anticipated additional QoS policies will be created as the list of WLANs grows. 5-34 AP-51xx Access Point Product Reference Guide 2. Click the Create button to configure a new QoS policy, or select a policy and click the Edit button to modify an existing QoS policy. The access point supports a maximum of 16 QoS policies. Network Management 5-35 3. Assign a name to the new or edited QoS policy that makes sense to the access point traffic receiving priority. More than one WLAN can use the same QoS policy. 4. Select the Support Voice prioritization checkbox to allow legacy voice prioritization. Certain products may not receive priority over other voice or data traffic. Consequently, ensure the Support Voice Prioritization checkbox is selected if using products that do not support Wi-Fi Multimedia (WMM) to provide preferred queuing for these VOIP products. If the Support Voice Prioritization checkbox is selected, the access point will detect non-
WMM capable (legacy) phones that connect to the access point and provide priority queueing for their traffic over normal data. NOTE Wi-fi functionality requires that both the access point and its associated clients are WMM-capable and have WMM enabled. WMM enabled devices can take advantage of their QoS functionality only if using applications that support WMM, and can assign an appropriate priority level to the traffic streams they generate. 5-36 AP-51xx Access Point Product Reference Guide 5. Use the two Multicast Address fields to specify one or two MAC addresses to be used for multicast applications. Some VoIP devices make use of multicast addresses. Using this mechanism ensures that the multicast packets for these devices are not delayed by the packet queue. 6. Use the drop-down menu to select the radio traffic best representing the network requirements of this WLAN. Options include:
manual Select the manual option if intending to manually set the Access Categories for the radio traffic within this WLAN. Only advanced users should manually configure the Access Categories, as setting them inappropriately could negatively impact the access points performance. 11ag - wifi 11b - wifi 11ag - default 11b - default 11ag voice Use this setting for high-end multimedia devices that using the s high rate 802.11a or 802.11g radio. Use this setting for high-end devices multimedia devices that use the 802.11b radio. Use this setting for typical data-centric MU traffic over the high rate 802.11a or 802.11g radio. Use this setting for typical data-centric MU traffic over the 802.11b radio. Use this setting for Voice-Over-IP traffic over the high rate 802.11a or 802.11g radio. 11b voice Use this setting for Voice-Over-IP traffic over the 802.11b radio.
!
CAUTION Symbol recommends using the drop-down menu to define the intended radio traffic within the WLAN. Once an option is selected, you do not need to adjust the values for the Access Categories. Unless qualified to do so, changing the Access Category default values could negatively impact the performance of the access point. 7. Select the Enable Wi-Fi Multimedia (WMM) QoS Extensions checkbox to configure the access points QoS Access Categories. The Access Categories are not configurable unless the checkbox is selected. Access Categories include:
Background Backgrounds traffic is typically of a low priority (file transfers, print jobs ect.). Background traffic typically does not have strict latency
(arrival) and throughput requirements. Network Management 5-37 Best Effort Video Voice Best Effort traffic includes traffic from legacy devices or applications lacking QoS capabilities. Best Effort traffic is negatively impacted by data transfers with long delays as well as multimedia traffic. Video traffic includes music streaming and application traffic requiring priority over all other types of network traffic. Voice traffic includes VoIP traffic and typically receives priority over Background and Best Effort traffic. 8. Configure the CW min and CW max (contention windows), AIFSN (Arbitrary Inter-Frame Space Number) and TXOPs Time (opportunity to transmit) for each Access Category. Their values are explained as follows. CW Min CW Max AIFSN TXOPs Time 32usec TXOPs Time ms The contention window minimum value is the least amount of time the MU waits before transmitting when there is no other data traffic on the network. The longer the interval, the lesser likelihood of collision. This value should be set to a smaller increment for higher priority traffic. Reduce the value when traffic on the WLAN is anticipated as being smaller. The contention window maximum value is the maximum amount of time the MU waits before transmitting when there is no other data traffic on the network. The longer the interval, the lesser likelihood of collision, but the greater propensity for longer transmit periods. The AIFSN is the minimum interframe space between data packets transmitted for the selected Access Category. This value should be set to a smaller increment for higher priority traffic to reduce packet delay time. The TXOPs Time is the interval the transmitting MU is assigned for transmitting. The default for Background traffic is 0. The same TXOPs values should be used for either the 802.11a or 802.11b/g radio, there is no difference. TXOP times range from 0.2 ms (background priority) to 3 ms (video priority) in a 802.11a network, and from 1.2 ms to 6 ms in an 802.11b/g network. The TXOP bursting capability greatly enhances the efficiency for high data rate traffic such as streaming video 5-38 AP-51xx Access Point Product Reference Guide 9. Click Apply to save any changes to the New QoS Policy or Edit QoS Policy screen to return to the Quality of Service Configuration screen. Navigating away from the screen without clicking Apply results in all changes to the screens being lost. 10. Click Cancel to securely exit the New QoS Policy or Edit QoS Policy screen to return to the Quality of Service Configuration screen. 11. Click Logout within the Quality of Service Configuration screen to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. U-APSD (WMM Power Save) Support The access point now supports Unscheduled Automatic Power Save Delivery (U-APSD), often referred to as WMM Power Save. U-APSD provides a periodic frame exchange between a voice capable MU and the access point during a VoIP call, while legacy power management is still utilized for typical data frame exchanges. The access point and its associated MU activate the new U-APSD power save approach when a VoIP traffic stream is detected. The MU then buffers frames from the voice traffic stream and sends a VoIP frame with an implicit "poll" request to its associated access point. The access point responds to the poll request with buffered VoIP stream frame(s). When a voice-enabled MU wakes up at a designated VoIP frame interval, it sends a VoIP frame with an implicit "poll" request to its associated access point. The AP -5131 responds to the poll request with buffered VoIP stream frame(s). NOTE The access point ships with the U-APSD feature disabled by default. It is automatically enabled when WMM is enabled for a WLAN. Thus, U-APSD is only functional when WMM is enabled. If WMM is disabled, then U-APSD is disabled as well. Network Management 5-39 5.3.1.4 Configuring WLAN Hotspot Support The access point enables hotspot operators to provide user authentication and accounting without a special client application. The access point uses a traditional Internet browser as a secure authentication device. Rather than rely on built-in 802.11security features to control access point association privileges, configure a WLAN with no WEP (an open network). The access point issues an IP address to the user using a DHCP server, authenticates the user and grants the user to access the Internet. When a user visits a public hotspot and wants to browse to a Web page, they boot up their laptop and associate with the local Wi-Fi network by entering the correct SSID. They then start a browser. The hotspot access controller forces this un-authenticated user to a Welcome page from the hotspot Operator that allows the user to login with a username and password. The access point hotspot functionality requires the following:
HTTP Redirection - Redirects unauthenticated users to a specific page specified by the Hotspot provider.
User authentication - Authenticates users using a Radius server.
Walled garden support - Enables a list of IP address (not domain names) to be accessed without authentication.
Billing system integration - Sends accounting records to a Radius accounting server.
!
CAUTION When using the access points hotspot functionality, ensure MUs are re-authenticated when changes are made to the characteristics of a hotspot enabled WLAN, as MUs within the WLAN will be dropped from access point device association. To configure hotspot functionality for an access point WLAN:
1. Ensure the Enable Hotspot checkbox is selected from within the target WLAN screen, and ensure the WLAN is properly configured. Any of the sixteen WLANs on the access point can be configured as a hotspot. For hotspot enabled WLANs, DHCP, DNS,HTTP and HTTP-S traffic is allowed (before you login to the hotspot), while TCP/IP packets are redirected to the port on the subnet to which the WLAN is mapped. For WLANs that are not hotspot-enabled, all packets are allowed. 2. Click the Configure Hotspot button within the WLAN screen to display the Hotspot Configuration screen for that target WLAN. 5-40 AP-51xx Access Point Product Reference Guide 3. Refer to the HTTP Redirection field to specify how the Login, Welcome, and Fail pages are maintained for this specific WLAN. The pages can be hosted locally or remotely. Use Default Files Use External URL Select the Use Default Files checkbox if the login, welcome and fail pages reside on the access point. Select the Use External URL checkbox to define a set of external URLs for hotspot users to access the login, welcome and fail pages. To create a redirected page, you need to have a TCP termination locally. On receiving the user credentials from the login page, the access point connects to a radius server, determines the identity of the connected wireless user and allows the user to access the Internet based on successful authentication. 4. Use the External URL field to specify the location of the login page, welcome page and fail page used for hotspot access. Defining these settings is required when the Use External URL checkbox has been selected within the HTTP Redirection field. Login Page URL Define the complete URL for the location of the Login page. The Login screen will prompt the hotspot user for a username and password to access the Welcome page. Network Management 5-41 Welcome Page URL Fail Page URL Define the complete URL for the location of the Welcome page. The Welcome page asserts the hotspot user has logged in successfully and can access the Internet. Define the complete URL for the location of the Fail page. The Fail screen asserts the hotspot authentication attempt failed, you are not allowed to access the Internet and you need to provide correct login information to access the Internet. 5. Click the White List Entries button (within the WhiteList Configuration field) to create a set of allowed destination IP addresses. These allowed destination IP addresses are called a White List. Ten configurable IP addresses are allowed for each WLAN. For more information, see Defining the Hotspot White List on page 5-42. 6. Refer to the Radius Accounting field to enable Radius accounting and specify the a timeout and retry value for the Radius server. Enable Accounting Server Address Radius Port Shared Secret Timeout Retries Select the Enable Accounting checkbox to enable a Radius Accounting Server used for Radius authentication for a target hotspot user. Specify an IP address for the external Radius Accounting server used to provide Radius accounting for the hotspot. If using this option, an internal Radius server cannot be used. The IP address of the internal Radius server is fixed at 127.0.0.1 and cannot be used for the external Radius server. Specify the port on which the Radius accounting server is listening. Specify a shared secret for accounting authentication for the hotspot. The shared secret is required to match the shared secret on the external Radius accounting server. Set the timeout value in seconds (1-255) used to timeout users accessing the Radius Accounting server if they have not successfully accessed the Accounting Server. Define the number of retries (1-10) the user is allowed to access the Radius Accounting Server if the first attempt fails. The default is 1. 7. Refer to the Radius Configuration field to define a primary and secondary Radius server port and shared secret password. 5-42 AP-51xx Access Point Product Reference Guide Select mode Pri Server IP Pri Port Pri Secret Sec Server IP Sec Port Sec Secret Use the Select mode drop-down menu to define whether an Internal or External server is to be used for the primary server. Define the IP address of the primary Radius server. This is the address of your first choice for Radius server. Enter the TCP/IP port number for the server acting as the primary Radius server. The default port is 1812. Enter the shared secret password used with the primary Radius Server. Define the IP address of the secondary Radius server. This is the address of your second choice for Radius server. Enter the TCP/IP port number for the server acting as the secondary Radius server. The default port is 1812. Enter the shared secret password used with the secondary Radius Server. 8. Click OK to save any changes to the Hotspot Configuration screen. Navigating away from the screen without clicking Apply results in all changes to the screens being lost. 9. Click Cancel (if necessary) to undo any changes made. Cancel reverts the settings displayed on the Hotspot Configuration screen to the last saved configuration. Defining the Hotspot White List To host a Login, Welcome or Fail page on the external Web server, the IP address of that Web server should be in access points White List. Network Management 5-43 When a client requests a URL from a Web server, the login handler returns an HTTP redirection status code (for example, 301 Moved Permanently), which indicates to the browser it should look for the page at another URL. This other URL can be a local or remote login page (based on the hotspot configuration). The login page URL is specified in the locations HTTP header. To host a Login page on the external Web server, the IP address of the Web server should be in the White list (list of IP addresses allowed to access the server) configuration. Ensure the Login page is designed so the submit action always posts the login data on the access point. To define the White List for a target WLAN:
1. Click the White List Entries button from within the WLANs Hotspot Config screen. 2. Click the Add button to define an IP address for an allowed destination IP address. 3. Select a White List entry and click the Del button to remove the address from the White List. 4. Click OK to return to the Hotspot Config screen where the configuration can be saved by clicking the Apply button. Now user enters his/her credentials on Login page and submits the page to AP5131. Login Handler will execute a CGI script, which will use this data as input. 5. Click Cancel to return to the Hotspot Config screen without saving any of the White List entries defined within the White List Entries screen. 5-44 AP-51xx Access Point Product Reference Guide 5.3.2 Setting the WLANs Radio Configuration Each access point WLAN can have a separate 802.11a or 802.11b/g radio configured and mapped to that WLAN. The first step is to enable the radio. One of two possible radio configuration pages are available on the access point depending on which model SKU is purchased. If the access point is a single-radio model, the Radio Configuration screen enables you to configure the single radio for either 802.11a or 802.11b/g use. The Radio Configuration screen contains two radio buttons whose selection is mutually exclusive. If the access point is a dual-radio model, the Radio Configuration screen enables you to configure one radio for 802.11a use and the other for 802.11b/g (no other alternatives exist for the dual-radio model). Using a dual-radio access point, individual 802.11a and 802.11b/g radios can be enabled or disabled using the Radio Configuration screen checkboxes. NOTE This section describes mesh networking (setting the radios base and client bridge configuration) at a high level. For a detailed overview on the theory of mesh networking, see Mesh Networking Overview on page 9-1. For detailed information on the implications of setting the mesh network configuration, see Configuring Mesh Networking Support on page 9-5. To review a use case on mesh networking, see Usage Scenario - Trion Enterprises on page 9-15. The Radio Configuration screen displays with two tabs. One tab each for the access points radios. Verify both tabs are selected and configured separately to enable the radio(s), and set their mesh networking definitions. To set the access point radio configuration (this example is for a dual-radio access point):
1. Select Network Configuration -> Wireless -> Radio Configuration from the access point menu tree. Network Management 5-45 2.
!
Enable the radio(s) using the Enable checkbox(es). Refer to RF Band of Operation parameter to ensure you are enabling the correct 802.11a or 802.11b/g radio. After the settings are applied within this Radio Configuration screen, the Radio Status and MUs connected values update. If this is an existing radio within a mesh network, these values update in real-time. CAUTION If a radio is disabled, be careful not to accidentally configure a new WLAN, expecting the radio to be operating when you have forgotten it was disabled. 3. Select the Base Bridge checkbox to allow the access point radio to accept client bridge connections from other access points in client bridge mode. The base bridge is the acceptor of mesh network data from those client bridges within the mesh network and never the initiator. If the Base Bridge checkbox has been selected, use the Max# Client Bridges parameter to define the client bridge load on a particular base bridge. 4. 5-46 AP-51xx Access Point Product Reference Guide The maximum number of client bridge connections per radio is 12, with 24 representing the maximum for dual-radio models. CAUTION An access point is Base Bridge mode logs out whenever a Client Bridge associates to the Base Bridge over the LAN connection. This problem is not experienced over the access points WAN connection. If this situation is experienced, log-in to the access point again. Once the settings within the Radio Configuration screen are applied (for an initial deployment), the current number of client bridge connections for this specific radio displays within the CBs Connected field. If this is an existing radio within a mesh network, this value updates in real-time. CAUTION A problem could arise if a Base Bridges Indoor channel is not available on an Outdoor Client Bridge's list of available channels. As long as an Outdoor Client Bridge has the Indoor Base Bridge channel in its available list of channels, it can associate to the Base Bridge.
!
!
5. Select the Client Bridge checkbox to enable the access point radio to initiate client bridge connections with other mesh network supported access points using the same WLAN. If the Client Bridge checkbox has been selected, use the Mesh Network Name drop-down menu to select the WLAN (ESS) the client bridge uses to establish a wireless link. The default setting, is (WLAN1). Symbol recommends creating (and naming) a WLAN specifically for mesh networking support to differentiate the Mesh supported WLAN from non-Mesh supported WLANs.
!
CAUTION An access point in client bridge mode cannot use a WLAN configured with a Kerberos or EAP 802.1x based security scheme, as these authentication types secure user credentials not the mesh network itself. NOTE Ensure you have verified the radio configuration for both Radio 1 and Radio 2 before saving the existing settings and exiting the Radio Configuration screen. Once the settings within the Radio Configuration screen are applied (for an initial deployment), the current number of base bridges visible to the radio displays within the BBs Visible field, and the number of base bridges currently connected to the radio displays Network Management 5-47 within the BBs Connected field. If this is an existing radio within a mesh network, these values update in real-time. 6. Click the Advanced button to define a prioritized list of access points to define Mesh Connection links. For a detailed overview on mesh networking and how to configure the radio for mesh networking support, see Configuring Mesh Networking on page 9-1. 7. Click Apply to save any changes to the Radio Configuration screen. Navigating away from the screen without clicking Apply results in all changes to the screens being lost.
!
CAUTION When defining a Mesh configuration and changes are saved, the mesh network temporarily goes down. The Mesh network is unavailable because the access point radio is reconfigured when applying changes. This can be problematic for users making changes within a deployed mesh network. If updating the mesh network using a LAN connection, the access point applet loses connection and the connection must be re-instated. If updating the mesh network using a WAN connection, the access point applet does not lose connection, but the mesh network is unavailable until the changes have been applied. 8. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on the Radio Configuration screen to the last saved configuration. 9. Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. Once the target radio has been enabled from the Radio Configuration screen, configure the radios properties by selecting it from the access point menu tree. For more information, see Configuring the 802.11a or 802.11b/g Radio on page 5-47. 5.3.2.1 Configuring the 802.11a or 802.11b/g Radio Configure an 802.11a or 802.11b/g radio by selecting the radios name (as defined using the 802.11a or 802.11b/g radio configuration screen described below) as a sub-menu item under the Radio Configuration menu item. Use the radio configuration screen to set the radios placement properties, define the radios threshold and QoS settings, set the radios channel and antenna settings and define beacon and DTIM intervals. To configure the access points 802.11a or 802.11b/g radio:

Select Network Configuration -> Wireless -> Radio Configuration -> Radio1 (default name) from the access point menu tree. 5-48 AP-51xx Access Point Product Reference Guide On a single-radio model, Radio1 could either be an 802.11a or 802.11b/g radio depending on which radio has been enabled. 2. Configure the Properties field to assign a name and placement designation for the radio. Placement MAC Address Radio Type Use the Placement drop-down menu to specify whether the radio is located outdoors or indoors. Default placement depends on the country of operation selected for the access point. The access point, like other Ethernet devices, has a unique, hardware encoded Media Access Control (MAC) or IEEE address. MAC addresses determine the device sending or receiving data. A MAC address is a 48-bit number written as six hexadecimal bytes separated by colons. For example: 00:A0:F8:24:9A:C8 The Radio Type parameter simply displays the radio type as 802.11a or 802.11b/g. This field is read only and always displays the radio type selected from the access point menu tree under the Radio Configuration item. Network Management 5-49 ERP Protection Extended Rate PHY (ERP) allows 802.11g MUs to interoperate with 802.11b only MUs. ERP Protection is managed automatically by the access point and informs users when 802.11b MUs are present within the access points coverage area. The presence of 802.11b MUs within the 802.11g coverage area negatively impacts network performance, so this feature should looked to as an indicator of why network performance has been degraded. 3. Configure the Radio Settings field to assign a channel, antenna diversity setting, radio transmit power level and data rate. Channel Setting Antenna Diversity Power Level The following channel setting options exist:
User Selection - If selected, use the drop-down menu to specify the legal channel for the intended country of operation. The drop-
down menu is not available if this option is not selected. Automatic Selection - Enables the access point to auto-select the channel of operation. For example, if three access points are operating on 802.11b/g, each access point would be set to a non-
overlapping channel (1, 6 and 11). If using the access points 802.11a radio, a Uniform Spreading option is available (and is the default setting for the 802.11a radio). To comply with Dynamic Frequency Selection (DFS) requirements in the European Union, the 802.11a radio uses a randomly selected channel each time the access point is powered on. Specifies the antenna selection for the 802.11a radio. Options include Primary Only, Secondary Only and Full Diversity. The default setting is Primary. However, Diversity can improve performance and signal reception in areas where interference is significant and is recommended when two antennas are supported. The Power Level parameter defines the transmit power of the 802.11a or 802.11b/g antenna(s). The values are expressed in dBm and mW. 5-50 AP-51xx Access Point Product Reference Guide 802.11 b/g mode Set Rates Specify b only, g only or b and g to define whether the 802.11b/
g radio transmits in the 2.4 Ghz band exclusively for 802.11b
(legacy) clients or transmits in the 2.4 Ghz band for 802.11g clients. Selecting b and g enables the access point to transmit to both b and g clients if legacy clients (802.11b) partially comprise the network. Select accordingly based on the MU requirements of the network. This parameter does not apply to access point 802.11a radios. Click the Set Rates button to display a window for selecting minimum and maximum data transmit rates for the radio. At least one Basic Rate must be selected as a minimum transmit rate value. Supported Rates define the data rate the radio defaults to if a higher selected data rate cannot be maintained. Click OK to implement the selected rates and return to the 802.11a or 802.11b/g radio configuration screen. Clicking Cancel reverts the Set Rates screen to the last saved configuration. Symbol recommends using the default rates unless qualified to understand the performance risks of changing them. The appearance of the Set Rates screen varies depending on the 802.11a or 802.11b/g used, as the dates rates available to the two radios are different. Network Management 5-51 4. Refer to the Beacon Settings field to set the radio beacon and DTIM intervals. Beacon Interval DTIM Interval The beacon interval controls the performance of power save stations. A small interval may make power save stations more responsive, but it will also cause them to consume more battery power. A large interval makes power save stations less responsive, but could increase power savings. The default is 100. Avoid changing this parameter as it can adversely affect performance. The DTIM interval defines how often broadcast frames are delivered for each of the four access point BSSIDs. If a system has an abundance of broadcast traffic and it needs to be delivered quickly, Symbol recommends decreasing the DTIM interval for that specific BSSID. However, decreasing the DTIM interval decreases the battery life on power save stations. The default is 10 for each BSSID. Symbol recommends using the default value unless qualified to understand the performance risks of changing it. 5-52 AP-51xx Access Point Product Reference Guide 5. Configure the Performance field to set the preamble, thresholds values, data rates and QoS values for the radio. Support Short Preamble RTS Threshold Set RF QoS The preamble is approximately 8 bytes of packet header generated by the access point and attached to the packet prior to transmission from the 802.11b radio. The preamble length for 802.11b transmissions is data rate dependant. The short preamble is 50% shorter than the long preamble. Leave the checkbox unselected if in a mixed MU/AP environment, as MUs and the access point are required to have the same RF Preamble settings for interoperability. The default is Disabled. The preamble length for 802.11a and 802.11g transmissions is the same, with no long or short preamble lengths. RTS allows the access point to use RTS (Request To Send) on frames longer than the specified length. The default is 2341bytes. Click the Set RF QoS button to display the Set RF QOS screen to set QoS parameters for the radio. Do not confuse with the QoS configuration screen used for a WLAN. The Set RF QoS screen initially appears with default values displayed. Select manual from the Select Parameter set drop-down menu to edit the CW min and CW max (contention window), AIFSN
(Arbitrary Inter-Frame Space Number) and TXOPs Time for each Access Category. These are the QoS policies for the 802.11a or 802.11b/g radio, not the QoS policies configured for the WLAN (as created or edited from the Quality of Service Configuration screen). Symbol recommends only advanced users manually set these values. If the type of data-traffic is known, use the drop-down menu to select a 11g-wifi, 11b-wifi, 11g-default, 11b-default, 11g-voice or 11b-voice option. Wifi represents multimedia traffic, default is typical data traffic and voice is for Voice-Over-IP supported wireless devices. Click OK to implement the selected QoS values and return to the 802.11a or 802.11b/g radio configuration screen. Clicking Cancel reverts the screen to the last saved configuration. Network Management 5-53 6. Select the Advanced Settings tab to strategically map BSSIDs to WLANs in order to define them as primary WLANs. 5-54 AP-51xx Access Point Product Reference Guide Defining Primary WLANs allows an administrator to dedicate BSSIDs (4 BSSIDs are available for mapping) to WLANs. From that initial BSSID assignment, Primary WLANs can be defined from within the WLANs assigned to BSSID groups 1 through 4. Each BSSID beacons only on the primary WLAN. The user should assign each WLAN to its own BSSID. In cases where more than four WLANs are required, WLANs should be grouped according to their security policies so all of the WLANs on a BSSID have the same security policy. It is generally a bad idea to have WLANs with different security policies on the same BSSID, as this will result in warning or error messages. NOTE If using a single-radio access point, there are 4 BSSIDs available. If using a dual-radio access point, 4 BSSIDs for the 802.11b/g radio and 4 BSSIDs for the 802.11a radio are available. WLAN BSSID BC/MC Cipher Lists the WLAN names available to the 802.11a or 802.11b/g radio that can be assigned to a BSSID. Assign a BSSID value of 1 through 4 to a WLAN in order to map the WLAN to a specific BSSID. A read only field displaying the downgraded BC/MC (Broadcast/
Multicast) cipher for a WLAN based on the BSSID and VLAN ID to which it has been mapped. Status Displays the following color coded status:
Red - Error (Invalid Configuration) Yellow - Warning (Broadcast Downgrade) Green - Good (Configuration is OK) Message Displays the verbal status of the WLAN and BSSID assignments. If the Status column displays green, the Message will typically be Configuration is OK. If yellow, a description of invalid configuration displays. 7. Use the Primary WLAN drop-down menu to select a WLAN from those WLANs sharing the same BSSID. The selected WLAN is the primary WLAN for the specified BSSID. 8. Click Apply to save any changes to the Radio Settings and Advanced Settings screens. Navigating away from the screen without clicking Apply results in changes to the screens being lost. Network Management 5-55 9. Click Undo Changes (if necessary) to undo any changes made to the screen and its sub-
screens. Undo Changes reverts the settings to the last saved configuration. 10. Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. 5.3.3 Configuring Bandwidth Management Settings The access point can be configured to grant individual WLANs network bandwidth priority levels. Use the Bandwidth Management screen to control the network bandwidth allotted to WLANs. Symbol recommends defining a weighed scheme as needed when WLAN traffic supporting a specific network segment becomes critical. 1. Select Network Configuration -> Wireless -> Bandwidth Management from the access point menu tree. 2. Use the Bandwidth Share Mode drop-down menu to define the order enabled WLANs receive access point services. Select one of the following three options:
First In First Out Round-Robin WLANs receive services from the access point on a first-come, first-served basis. This is the default setting. Each WLAN receives access point services in turn as long the access point has data traffic to forward. 5-56 AP-51xx Access Point Product Reference Guide Weighted Round-
Robin If selected, a weighting (prioritization) scheme (configured within the QoS Configuration screen) is used to define which WLANs receive access point resources first. 3. Configure the Bandwidth Share for Each WLAN field to set a raw weight (for WLANs using the Weighted Round-Robin option) for each WLAN. The weight% changes as the weight is entered. If a WLAN has not been enabled from the Wireless screen, it is not configurable using the Bandwidth Management screen. To enable a specific WLAN, see Enabling Wireless LANs (WLANs) on page 5-22. WLAN Name Weight Weight (%) QoS Policy Displays the name of the WLAN. This field is read-only. To change the name of the WLAN, see Creating/Editing Individual WLANs on page 5-24. This column is not available unless Weighted Round-Robin is selected. Assign a weight to each WLAN. This percentage equals the access point bandwidth share for that WLAN when network traffic is detected. This column is automatically updated with the appropriate WLAN bandwidth share when the Weight is modified. Displays the name of the QoS policy defined for each WLAN within the Quality of Service for WLAN screen. If no policy has been set, the WLAN uses the default policy. For information on assigning QoS policies for specific WLANs, see Setting the WLAN Quality of Service (QoS) Policy on page 5-33. 4. Click Apply to save any changes to the Bandwidth Management screen. Navigating away from the screen without clicking Apply results in all changes to the screens being lost. 5. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on the Bandwidth Management screen to the last saved configuration. 6. Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. Network Management 5-57 NOTE Though the Rogue AP and Firewall features appear after the Bandwidth Management features within the access point menu tree, they are described in Chapter 6, Configuring Access Point Security on page 6-1, as both items are data protection functions. More specifically, see, Configuring Firewall Settings on page 6-25 and Configuring Rogue AP Detection on page 6-52. 5.4 Configuring Router Settings The access point router uses routing tables and protocols to forward data packets from one network to another. The access point router manages traffic within the network, and directs traffic from the WAN to destinations on the access point managed LAN. Use the access point Router screen to view the router's connected routes. To access the Router screen. 1. Select Network Configuration -> Router from the access point menu tree. 2. Refer to the access point Router Table field to view existing routes. The access point Router Table field displays a list of connected routes between an enabled subnet and the router. These routes can be changed by modifying the IP address and subnet masks of the enabled subnets. The information in the access point Router Table is dynamically generated from settings applied on the WAN screen. The destination for each subnet is its IP address. The subnet 5-58 AP-51xx Access Point Product Reference Guide 3. 4. mask (or network mask) and gateway settings are those belonging to each subnet. Displayed interfaces are those associated with destination IP addresses. To change any of the network address information within the WAN screen, see Configuring WAN Settings on page 5-14. From the Use Default Gateway drop-down menu, select the WAN or either of the two LANs (if enabled) to server as the default gateway to forward data packets from one network to another. To set or view the RIP configuration, click the RIP Configuration button. Routing Information Protocol (RIP) is an interior gateway protocol that specifies how routers exchange routing-table information. The Router screen also allows the administrator to select the type of RIP and the type of RIP authentication used by the switch. For more information on configuring RIP, see Setting the RIP Configuration on page 5-58. 5. Use the User Defined Routes field to add or delete static routes. The User Defined Routes field allows the administrator to view, add or delete internal static
(dedicated) routes. a. Click the Add button to create a new table entry. b. Highlight an entry and click the Del (delete) button to remove an entry. c. Specify the destination IP address, subnet mask, and gateway information for the internal static route. d. Select an enabled subnet from the Interface(s) columns drop-down menu to complete the table entry. Information in the Metric column is a user-defined value (from 1 to 65535) used by router protocols to determine the best hop routes. 6. Click the Apply button to save the changes. 7. Click Logout to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. 5.4.1 Setting the RIP Configuration To set the RIP configuration:
1. From within the RIP Configuration field, select the RIP Type from the drop-down menu. The following options are available:
No RIP The No RIP option prevents the access points router from exchanging routing information with other routers. Routing information may not be appropriate to share, for example, if the access point manages a private LAN. Network Management 5-59 RIP v1 RIP v2 (v1 compat) RIP v2 RIP version 1 is a mature, stable, and widely supported protocol. It is well suited for use in stub networks and in small autonomous systems that do not have enough redundant paths to warrant the overhead of a more sophisticated protocol. RIP version 2 (compatible with version 1) is an extension of RIP v1s capabilities, but it is still compatible with RIP version 1. RIP version 2 increases the amount of packet information to provide the a simple authentication mechanism to secure table updates. RIP version 2 enables the use of a simple authentication mechanism to secure table updates. More importantly, RIP version 2 supports subnet masks, a critical feature not available in RIP version 1. This selection is not compatible with RIP version 1 support. 2. Select a routing direction from the RIP Direction drop-down menu. Both (for both directions), Rx only (receive only), and TX only (transmit only) are available options. 5-60 AP-51xx Access Point Product Reference Guide 3. If RIP v2 or RIP v2 (v1 compat) is the selected RIP type, the RIP v2 Authentication field becomes active. Select the type of authentication to use from the Authentication Type drop-down menu. Available options include:
None Simple MD5 This option disables the RIP authentication. This option enable RIP version 2s simple authentication mechanism. This setting activates the Password (Simple Authentication) field. This option enables the MD5 algorithm for data verification. MD5 takes as input a message of arbitrary length and produces a 128-
bit fingerprint. The MD5 setting activates the RIP v2 Authentication settings for keys (below). Network Management 5-61 4. 5. If the Simple authentication method is selected, specify a password of up to 15 alphanumeric characters in the Password (Simple Authentication) area. If the MD5 authentication method is selected, fill in the Key #1 field (Key #2 is optional). Enter any numeric value between 0 and 256 into the MD5 ID area. Enter a string consisting of up to 16 alphanumeric characters in the MD5 Auth Key area. 6. Click the OK button to return to the Router screen. From there, click Apply to save the changes. 5-62 AP-51xx Access Point Product Reference Guide Configuring Access Point Security Security measures for the access point and its WLANs are critical. Use the available access point security options to protect the access point LAN from wireless vulnerabilities, and safeguard the transmission of RF packets between the access point and its associated MUs. WLAN security can be configured on an ESS by ESS basis on the access point. Sixteen separate ESSIDs (WLANs) can be supported on an access point, and must be managed (if necessary) between the 802.11a and 802.11b/g radio. The user has the capability of configuring separate security policies for each WLAN. Each security policy can be configured based on the authentication (Kerberos, 802.1x EAP) or encryption (WEP, KeyGuard, WPA/TKIP or WPA2/CCMP) scheme best suited to the coverage area that security policy supports. The access point can also create VPN tunnels to securely route traffic through a IPSEC tunnel and block transmissions with devices interpreted as Rogue APs. 6-2 AP-51xx Access Point Product Reference Guide NOTE Security for the access point can be configured in various locations throughout the access point menu structure. This chapter outlines the security options available to the access point, and the menu locations and steps required to configure specific security measures. 6.1 Configuring Security Options To configure the data protection options available on the access point, refer to the following:
To set an administrative password for secure access point logins, see Setting Passwords on page 6-3.
Refer to Enabling Authentication and Encryption Schemes on page 6-5 to display security policy screens used to configure the authetication and encryption schemes available to the access point. These security policies can be used on more than one WLAN.
To create a security policy supporting 802.1x EAP, see Configuring 802.1x EAP Authentication on page 6-11.

Configuring Access Point Security 6-3 6.2 Setting Passwords Before setting the access point security parameters, verify an administrative password for the access point has been created to restrict access to the device before advanced device security is configured. To password protect and restrict access point device access:
1. Connect a wired computer to the access point LAN port using a standard CAT-5 cable. 2. Set up the computer for TCP/IP DHCP network addressing and make sure the DNS settings are not hardcoded. 3. Start up Internet Explorer (with Sun Micro Systems Java Runtime Environment (JRE) 1.5 or higher installed) and type in the default IP address in the address field: 192.168.0.1. If the default IP address has been changed, ensure the correct IP address is entered. The access point Login screen displays. NOTE For optimum compatibility use Sun Microsystems JRE 1.5 or higher
(available from Suns Web site), and be sure to disable Microsofts Java Virtual Machine if it is installed. NOTE DNS names are not supported as a valid IP address for the access point. The user is required to enter a numerical IP address. 4. Log in using the admin as the default User ID and symbol as the default Password. 6-4 AP-51xx Access Point Product Reference Guide If the default login is successful, the Change Admin Password window displays. Change the default login and password to significantly decrease the likelihood of hacking.
!
5. CAUTION Restoring the access points configuration back to default settings changes the administrative password back to symbol. If restoring the configuration back to default settings, be sure you change the administrative password accordingly. Enter the previous password and the new admin password in the two fields provided. Click the Apply button. Once the admin password has been created/updated, the System Settings screen displays. If the access point has not had its System Settings (device name, location etc.) configured, see Configuring System Settings on page 4-2. Once the password has been set, refer back to Configuring Security Options on page 6-2 to determine which access point security feature to configure next. 6.2.1 Resetting the Access Point Password The access point Command Line Interface (CLI) enables users who forget their password to reset it to the factory default (symbol). From there, a new password can be defined. To reset the password back to its default setting:
1. Connect one end of a null modem serial cable to the access points serial connector. 2. Attach the other end of the null modem serial cable to the serial port of a PC running HyperTerminal or a similar emulation program. 3. Set the HyperTerminal program to use 19200 baud, 8 data bits, 1 stop bit, no parity, no flow control and auto-detect for terminal emulation. Press <ESC> or <Enter> to access the CLI. 4. Configuring Access Point Security 6-5 A serial connection has now been established and the user should be able to view the serial connection window. 5. Reset the access point. An access point can be reset by removing and re-inserting the LAN cable or removing and re-inserting the power cable. As the access point is re-booting, a Press esc key to run boot firmware message displays. 6. Quickly press <ESC>.
!
7. CAUTION If the <ESC> key is not pressed within three seconds after the Press esc key to run boot firmware message displays, the access point will continue to boot. If the <ESC> key is pressed within three seconds a boot> prompt displays. Type the following at the boot prompt:
passwd default 8. Reset the access point by typing the following at the boot prompt:
reset system When the access point re-boots again, the password will return to its default value of symbol. You can now access the access point. 6.3 Enabling Authentication and Encryption Schemes To complement the built-in firewall filters on the WAN side of the access point, the WLAN side of the access point supports authentication and encryption schemes. Authentication is a challenge-
response procedure for validating user credentials such as username, password, and sometimes secret-key information. The access point provides two schemes for authenticating users: 802.1x EAP and Kerberos. Encryption applies a specific algorithm to alter its appearance and prevent unauthorized reading. Decryption applies the algorithm in reverse to restore the data to its original form. Sender and receiver must employ the same encryption/decryption method to interoperate. Wired Equivalent Privacy (WEP) is available in two encryption modes: 40 bit (also called WEP 64) and 104 bit (also called WEP 128). The 104-bit encryption mode provides a longer algorithm (better security) that takes longer to decode (hack) than the 40-bit encryption mode. 6-6 AP-51xx Access Point Product Reference Guide Each WLAN (16 WLANs available in total to an access point regardless of the model) can have a separate security policy. However, more than one WLAN can use the same security policy. Therefore, to avoid confusion, do not name security policies the same name as WLANs. Once security policies have been created, they are selectable within the Security field of each WLAN screen. If the existing default security policy does not satisfy the data protection requirements of a specific WLAN, a new security policy (using the authentication and encryption schemes discussed above) can be created. To enable an existing WLAN security policy or create a new policy:
1. Select Network Configuration -> Wireless -> Security from the access point menu tree. The Security Configuration screen displays. If a new security policy is required, click the Create button. 2. The New Security Policy screen displays with the Manually Pre-shared key/No authentication and No Encryption options selected. Naming and saving such a policy (as is) would provide no security and might only make sense in a guest network wherein no sensitive data is either transmitted or received. However, selecting any other authetnication or encryption checkbox displays a configuration field for the selected security scheme within the New Security Policy screen. Configuring Access Point Security 6-7 NOTE An existing security policy can be edited from the Security Configuration screen by selecting an existing policy and clicking the Edit button. Use the Edit Security Policy screen to edit the policy. For more information on editing an existing security policy, refer to security configuration sections described in steps 4 and 5. 3. Use the Name field to define a logical security policy name. Remember, multiple WLANs can share the same security policy, so be careful not to name security policies after specific WLANs or risk defining a WLAN to single policy. Symbol recommends naming the policy after the attributes of the authentication or encryption type selected (for example, WPA2 Allow TKIP). Enable and configure an Authentication option if necessary for the target security policy. 4. Manually Pre-Shared Key / No Authentication Kerberos 802.1x EAP Select this button to disable authentication. This is the default value for the Authentication field. Select the Kerberos button to display the Kerberos Configuration field within the New Security Policy screen. For specific information on configuring Kerberos, see Configuring Kerberos Authentication on page 6-9. Select the 802.1x EAP button to display the 802.1x EAP Settings field within the New Security Policy screen. For specific information on configuring EAP, see Configuring 802.1x EAP Authentication on page 6-11. 5. Enable and configure an Encryption option if necessary for the target security policy. No Encryption WEP 64 (40-bit key) If No Encryption is selected, encryption is disabled for the security policy. If security is not an issue, this setting avoids the overhead an encryption protocol causes on the access point. No Encryption is the default value for the Encryption field. Select the WEP 64 (40 bit key) button to display the WEP 64 Settings field within the New Security Policy screen. For specific information on configuring WEP 64, see Configuring WEP Encryption on page 6-16. 6-8 AP-51xx Access Point Product Reference Guide KeyGuard WEP 128 (104-bit key) Select the WEP 128 (104 bit key) button to display the WEP 128 Settings field within the New Security Policy screen. For specific information on configuring WEP 128, see Configuring WEP Encryption on page 6-16. Select the KeyGuard button to display the KeyGuard Settings field within the New Security Policy screen.

Click Cancel to return to the target WLAN screen without keeping any of the changes made within the New Security Policy screen. 6.4 Configuring Kerberos Authentication Kerberos (designed and developed by MIT) provides strong authentication for client/server applications using secret-key cryptography. Using Kerberos, a client must prove its identity to a server
(and vice versa) across an insecure network connection. Once a client and server use Kerberos to prove their identity, they can encrypt all communications to assure privacy and data integrity. Kerberos can only be used on the access point with Symbol clients.
!
CAUTION Kerberos makes no provisions for host security. Kerberos assumes that it is running on a trusted host with an untrusted network. If host security is compromised, Kerberos is compromised as well Kerberos uses the Network Time Protocol (NTP) for synchronizing the clocks of its Key Distribution Center (KDC) server(s). Use the NTP Servers screen to specify the IP addresses and ports of available NTP servers. Kerberos requires the Enable NTP on access point checkbox be selected for authentication to function properly. See Configuring Network Time Protocol (NTP) on page 4-31 to configure the NTP server. NOTE If 802.11a is selected as the radio used for a specific WLAN, the WLAN cannot use a Kerberos supported security policy, as no 802.11a clients can support Kerberos on the access point. To configure Kerberos on the access point:
1. Select Network Configuration -> Wireless -> Security from the access point menu tree. If security policies supporting Kerberos exist, they appear within the Security Configuration screen. These existing policies can be used as is, or their properties edited by clicking the Edit button. To configure a new security policy supporting Kerberos, continue to step 2. 2. Click the Create button to configure a new policy supporting Kerberos. The New Security Policy screen displays with no authentication or encryption options selected. 6-10 AP-51xx Access Point Product Reference Guide 3. Select the Kerberos radio button. 4. The Kerberos Configuration field displays within the New Security Policy screen. Ensure the Name of the security policy entered suits the intended configuration or function of the policy. 5. Set the Kerberos Configuration field as required to define the parameters of the Kerberos authentication server and access point. Realm Name Primary KDC Specify a realm name that is case-sensitive, for example, SYMBOL.COM. The realm name is the name domain/realm name of the KDC Server. A realm name functions similarly to a DNS domain name. In theory, the realm name is arbitrary. However, in practice a Kerberos realm is named by uppercasing the DNS domain name that is associated with hosts in the realm. Specify a numerical (non-DNS) IP address and port for the primary Key Distribution Center (KDC). The KDC implements an Authentication Service and a Ticket Granting Service, whereby an authorized user is granted a ticket encrypted with the user's password. The KDC has a copy of every user password.

Configuring Access Point Security 6-11 Backup KDC Remote KDC Port Optionally, specify a numerical (non-DNS) IP address and port for a backup KDC. Backup KDCs are referred to as slave servers. The slave server periodically synchronizes its database with the primary (or master) KDC. Optionally, specify a numerical (non-DNS) IP address and port for a remote KDC. Kerberos implementations can use an administration server allowing remote manipulation of the Kerberos database. This administration server usually runs on the KDC. Specify the ports on which the Primary, Backup and Remote KDCs reside. The default port number for Kerberos Key Distribution Centers is Port 88. 6. Click the Apply button to return to the WLAN screen to save any changes made within the Kerberos Configuration field of the New Security Policy screen. 7. Click the Cancel button to undo any changes made within the Kerberos Configuration field and return to the WLAN screen. This reverts all settings for the Kerberos Configuration field to the last saved configuration. 6.5 Configuring 802.1x EAP Authentication The IEEE 802.1x standard ties the 802.1x EAP authentication protocol to both wired and wireless LAN applications. The EAP process begins when an unauthenticated supplicant (client device) tries to connect with an authenticator (in this case, the authentication server). The access point passes EAP packets from the client to an authentication server on the wired side of the access point. All other packet types are blocked until the authentication server (typically, a RADIUS server) verifies the MUs identity. To configure 802.1x EAP authentication on the access point:
1. Select Network Configuration -> Wireless -> Security from the access point menu tree. If security policies supporting 802.1x EAP exist, they appear within the Security Configuration screen. These existing policies can be used as is, or their properties edited by clicking the Edit button. To configure a new security policy supporting 802.1x EAP, continue to step 2. 2. Click the Create button to configure a new policy supporting 802.1x EAP. The New Security Policy screen displays with no authentication or encryption options selected. 6-12 AP-51xx Access Point Product Reference Guide 3. Select the 802.1x EAP radio button. 4. 5. The 802.1x EAP Settings field displays within the New Security Policy screen. Ensure the Name of the security policy entered suits the intended configuration or function of the policy. If using the access points Internal Radius server, leave the Radius Server drop-down menu in the default setting of Internal. If an external Radius server is used, select External from the drop-down menu. 6. Configure the Server Settings field as required to define address information for the authentication server. The appearance of the Server Settings field varies depending on whether Internal or External has been selected from the Radius Server drop-down menu. Configuring Access Point Security 6-13 Radius Server Address RADIUS Port RADIUS Shared Secret If using an External Radius Server, specify the numerical (non-DNS) IP address of a primary Remote Dial-In User Service (Radius) server. Optionally, specify the IP address of a secondary server. The secondary server acts as a failover server if the primary server cannot be contacted. An ISP or a network administrator provides these addresses. Radius is a client/server protocol and software enabling remote-
access clients to communicate with a server used to authenticate users and authorize access to the requested system or service. This setting is not available if Internal has been selected from the Radius Server drop-down menu. If using an External Radius Server, specify the port on which the primary Radius server is listening. Optionally, specify the port of a secondary (failover) server. Older Radius servers listen on ports 1645 and 1646. Newer servers listen on ports 1812 and 1813. Port 1645 or 1812 is used for authentication. Port 1646 or 1813 is used for accounting. The ISP or a network administrator needs to confirm the appropriate primary and secondary port numbers for authentication. This setting is not available if Internal has been selected from the Radius Server drop-down menu. Specify a shared secret for authentication on the Internal or Primary Radius server (External Radius Server only). The shared secret is required to match the shared secret on the Radius server. Optionally, specify a shared secret for a secondary (failover) server. Use shared secrets to verify Radius messages (with the exception of the Access-Request message) sent by a Radius enabled device configured with the same shared secret. Apply the qualifications of a well-chosen password to the generation of a shared secret. Generate a random, case-sensitive string using letters, numbers and symbols. Verify the shared secret is at least 22 characters to protect the Radius server from brute-
force attacks. An example of a strong and secure shared secret is:

The items within this tab could be enabled or disabled depending on whether internal or External has been selected from the Radius Server drop-down menu. Internal/External Accounting If using an Internal Radius server, select Disabled (no Internal Accounting), Internal Only or Both Internal and External. Selecting Both Internal and External displays additional parameters for configuring the External Radius Server. If using an External Radius server, simply select Enable or Disable to allow or deny external accounting with the external Radius server. External Radius Server Address Specify the IP address of the external Radius server used to provide Radius accounting. External Radius Port Specify the port on which the Radius server is listening. External Radius Shared Secret MU Timeout Retries Enable Syslog Specify a shared secret for authentication. The shared secret is required to match the shared secret on the Radius server. Specify the time (in seconds) for the access points retransmission of EAP-Request packets. The default is 10 seconds. If this time is exceeded, the authetnication session is terminated. Specify the number of retries for the MU to retransmit a missed frame to the Radius server before it times out of the authentication session. The default is 2 retries. Select the Enable Syslog checkbox to enable syslog messages relating to EAP events to be written to the specified syslog server. Syslog Server IP Address Enter the IP address of the destination syslog server to be used to log EAP events. 8. Select the Reauthentication tab as required to define authentication connection policies, intervals and maximum retries. The items within this tab are identical regardless of whether Internal or External is selected from the Radius Server drop-down menu. Enable Reauthentication Select the Enable Reauthentication checkbox to configure a wireless connection policy so MUs are forced to reauthenticate periodically. Periodic repetition of the EAP process provides ongoing security for current authorized connections. Configuring Access Point Security 6-15 Period (30-9999) secs Set the EAP reauthentication period to a shorter time interval (at least 30 seconds) for tighter security on the WLAN's connections. Set the EAP reauthentication period to a longer time interval (at most, 9999 seconds) to relax security on wireless connections. The reauthentication period setting does not affect wireless connection throughput. The default is 3600 seconds. Max. Retries (1-99) retries Define the maximum number of MU retries to reauthenticate after failing to complete the EAP process. Failure to reauthenticate in the specified number of retries results in a terminated connection. The default is 2 retries. 9. Select the Advanced Settings tab as required to specify a MU quiet period, timeout interval, transmit period, and retry period for MUs and the authentication server. The items within this tab are identical regardless of whether Internal or External is selected from the Radius Server drop-down menu. MU Quiet Period

This reverts all settings for the 802.1x EAP Settings field to the last saved configuration. 6.6 Configuring WEP Encryption Wired Equivalent Privacy (WEP) is a security protocol specified in the IEEE Wireless Fidelity (Wi-Fi) standard. WEP is designed to provide a WLAN with a level of security and privacy comparable to that of a wired LAN. WEP may be all that a small-business user needs for the simple encryption of wireless data. However, networks that require more security are at risk from a WEP flaw. The existing 802.11 standard alone offers administrators no effective method to update keys. To configure WEP on the access point:
1. Select Network Configuration -> Wireless -> Security from the access point menu tree. If security policies supporting WEP exist, they appear within the Security Configuration screen. These existing policies can be used as is, or their properties edited by clicking the Edit button. To configure a new security policy supporting WEP, continue to step 2. 2. Click the Create button to configure a new policy supporting WEP. The New Security Policy screen displays with no authentication or encryption options selected. 3. Select either the WEP 64 (40 bit key) or WEP 128 (104 bit key) radio button. The WEP 64 Settings or WEP 128 Settings field displays within the New Security Policy screen. Ensure the Name of the security policy entered suits the intended configuration or function of the policy. 4. Configuring Access Point Security 6-17 5. Configure the WEP 64 Settings or WEP 128 Settings field as required to define the Pass Key used to generate the WEP keys. These keys must be the same between the access point and its MU to encrypt packets between the two devices. Pass Key Keys #1-4 Specify a 4 to 32 character pass key and click the Generate button. The pass key can be any alphanumeric string. The access point, other proprietary routers and Symbol MUs use the algorithm to convert an ASCII string to the same hexadecimal number. MUs without Symbol adapters need to use WEP keys manually configured as hexadecimal numbers. Use the Key #1-4 areas to specify key numbers. The key can be either a hexadecimal or ASCII depending on which option is selected from the drop-down menu. For WEP 64 (40-bit key), the keys are 10 hexadecimal characters in length or 5 ASCII characters. For WEP 128 (104-bit key), the keys are 26 hexadecimal characters in length or 13 ASCII characters. Select one of these keys for activation by clicking its radio button. Default (hexadecimal) keys for WEP 64 include:
6-18 AP-51xx Access Point Product Reference Guide Key 1 Key 2 Key 3 Key 4 1011121314 2021222324 3031323334 4041424344 Default (hexadecimal) keys for WEP 128 include:

Click the Apply button to save any changes made within the WEP 64 Setting or WEP 128 Setting field of the New Security Policy screen. 7. Click the Cancel button to undo any changes made within the WEP 64 Setting or WEP 128 Setting field and return to the WLAN screen. This reverts all settings to the last saved configuration. 6.7 Configuring KeyGuard Encryption KeyGuard is a proprietary encryption method developed by Symbol Technologies. KeyGuard is Symbol's enhancement to WEP encryption, and was developed before the finalization of WPA-TKIP. This encryption implementation is based on the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11i. WPA2-CCMP (not KeyGuard) offers the highest level of security among the encryption methods available with the access point. 1. Select Network Configuration -> Wireless -> Security from the access point menu tree. If security policies supporting KeyGuard exist, they appear within the Security Configuration screen. These existing policies can be used as is, or their properties edited by clicking the Edit button. To configure a new security policy supporting KeyGuard, continue to step 2. 2. Click the Create button to configure a new policy supporting KeyGuard. The New Security Policy screen displays with no authentication or encryption options selected.

These keys must be the same between the access point and its MU to encrypt packets between the two devices Pass Key Keys #1-4 Specify a 4 to 32 character pass key and click the Generate button. The pass key can be any alphanumeric string. The access point, other proprietary routers, and Symbol MUs use the algorithm to convert an ASCII string to the same hexadecimal number. MUs without Symbol adapters need to use WEP keys manually configured as hexadecimal numbers. Use the Key #1-4 areas to specify key numbers. The key can be either a hexadecimal or ASCII depending on which option is selected from the drop-down menu. The keys are 26 hexadecimal characters in length or 13 ASCII characters. Select one of these keys for activation by clicking its radio button. 6-20 AP-51xx Access Point Product Reference Guide Default (hexadecimal) keys for KeyGuard include:
Key 1 Key 2 Key 3 Key 4 101112131415161718191A1B1C 202122232425262728292A2B2C 303132333435363738393A3B3C 404142434445464748494A4B4C 6. Select the Allow WEP128 Clients checkbox (from within the KeyGuard Mixed Mode field) to enable WEP128 clients to associate with an access points KeyGuard supported WLAN. The WEP128 clients must use the same keys as the KeyGuard clients to interoperate within the access points KeyGuard supported WLAN. 7. Click the Apply button to save any changes made within the KeyGuard Setting field of the New Security Policy screen. 8. Click the Cancel button to undo any changes made within the KeyGuard Setting field and return to the WLAN screen. This reverts all settings to the last saved configuration. 6.8 Configuring WPA Using TKIP Wi-Fi Protected Access (WPA) is a robust encryption scheme specified in the IEEE Wireless Fidelity
(Wi-Fi) standard, 802.11i. WPA provides more sophisticated data encryption than WEP. WPA is designed for corporate networks and small-business environments where more wireless traffic allows quicker discovery of encryption keys by an unauthorized person. WPA's encryption method is Temporal Key Integrity Protocol (TKIP). TKIP addresses WEPs weaknesses with a re-keying mechanism, a per-packet mixing function, a message integrity check, and an extended initialization vector. WPA also provides strong user authentication based on 802.1x EAP. To configure WPA-TKIP encryption on the access point:
1. Select Network Configuration -> Wireless -> Security from the access point menu tree. If security policies supporting WPA-TKIP exist, they appear within the Security Configuration screen. These existing policies can be used as is, or their properties edited by clicking the Edit button. To configure a new security policy supporting WPA-TKIP, continue to step 2. 2. Click the Create button to configure a new policy supporting WPA-TKIP. The New Security Policy screen displays with no authentication or encryption options selected. Configuring Access Point Security 6-21 3. Select the WPA/TKIP radio button. 4. The WPA/TKIP Settings field displays within the New Security Policy screen. Ensure the Name of the security policy entered suits the intended configuration or function of the policy. 5. Configure the Key Rotation Settings area as needed to broadcast encryption key changes to MUs and define the broadcast interval. Broadcast Key Rotation Update broadcast keys every (300-
604800 seconds) Select the Broadcast Key Rotation checkbox to enable or disable the broadcasting of encryption-key changes to MUs. Only broadcast key changes when required by associated MUs to reduce the transmissions of sensitive key information. This value is disabled by default. Specify a time period in seconds for broadcasting encryption-key changes to MUs. Set key broadcasts to a shorter time interval (at least 30 seconds) for tighter security on the WLAN's wireless connections. Set key broadcasts to a longer time interval (at most, 80000 seconds) to extend the key times for wireless connections. Default is 86,400 seconds. 6. Configure the Key Settings area as needed to set an ASCII Passphrase and key values. 6-22 AP-51xx Access Point Product Reference Guide ASCII Passphrase 256-bit Key To use an ASCII passphrase (and not a hexadecimal value), select the checkbox and enter an alphanumeric string of 8 to 63 characters. The alphanumeric string allows character spaces. The access point converts the string to a numeric value. This passphrase saves the administrator from entering the 256-bit key each time keys are generated. To use a hexadecimal value (and not an ASCII passphrase), select the checkbox and enter 16 hexadecimal characters into each of the four fields displayed. Default (hexadecimal) 256-bit keys for WPA/TKIP include:
1011121314151617 18191A1B1C1D1E1F 2021222324252627 28292A2B2C2D2E2F 7. Click the Apply button to save any changes made within the WPA/TKIP Settings field of the New Security Policy screen. 8. Click the Cancel button to undo any changes made within the WPA/TKIP Settings field and return to the WLAN screen. This reverts all settings to the last saved configuration. 6.9 Configuring WPA2-CCMP (802.11i) WPA2 is a newer 802.11i standard that provides even stronger wireless security than Wi-Fi Protected Access (WPA) and WEP. CCMP is the security standard used by the Advanced Encryption Standard
(AES). AES serves the same function TKIP does for WPA-TKIP. CCMP computes a Message Integrity Check (MIC) using the proven Cipher Block Chaining (CBC) technique. Changing just one bit in a message produces a totally different result. WPA2/CCMP is based on the concept of a Robust Security Network (RSN), which defines a hierarchy of keys with a limited lifetime (similar to TKIP). Like TKIP, the keys the administrator provides are used to derive other keys. Messages are encrypted using a 128-bit secret key and a 128-bit block of data. The end result is an encryption scheme as secure as any the access point provides. To configure WPA2-CCMP on the access point:
1. Select Network Configuration -> Wireless -> Security from the access point menu tree. Configuring Access Point Security 6-23 If security policies supporting WPA2-CCMP exist, they appear within the Security Configuration screen. These existing policies can be used as is, or their properties edited by clicking the Edit button. To configure a new security policy supporting WPA2-CCMP, continue to step 2. 2. Click the Create button to configure a new policy supporting WPA2-CCMP. The New Security Policy screen displays with no authentication or encryption options selected. 3. Select the WPA2/CCMP (802.11i) checkbox. 4. The WPA2/CCMP Settings field displays within the New Security Policy screen. Ensure the Name of the security policy entered suits the intended configuration or function of the policy. 5. Configure the Key Rotation Settings field as required to set Broadcast Key Rotation and the update interval. 6-24 AP-51xx Access Point Product Reference Guide Broadcast Key Rotation Update broadcast keys every (300-
604800 seconds) Select the Broadcast Key Rotation checkbox to enable or disable the broadcasting of encryption key changes to MUs. Only broadcast key changes when required by associated MUs to reduce the transmissions of sensitive key information. This option is disabled by default. Specify a time period in seconds for broadcasting encryption key changes to MUs. Set key broadcasts to a shorter interval (at least 30 seconds) for tighter security on the WLAN's wireless connections. Set key broadcasts to a longer interval to extend the key times for wireless connections. Default is 86,400 seconds. 6. Configure the Key Settings area as needed to set an ASCII Passphrase and 128-bit key. ASCII Passphrase 256-bit Key To use an ASCII passphrase (and not a hexadecimal value), select the checkbox enter an alphanumeric string of 8 to 63 characters. The string allows character spaces. The access point converts the string to a numeric value. This passphrase saves the administrator from entering the 256-bit key each time keys are generated. To use a hexadecimal value (and not an ASCII passphrase), select the checkbox and enter 16 hexadecimal characters into each of the four fields displayed. Default (hexadecimal) 256-bit keys for WP2A/CCMP include:
1011121314151617 18191A1B1C1D1E1F 2021222324252627 28292A2B2C2D2E2F 7. Configure the WPA2-CCMP Mixed Mode field as needed to allow TKIP and WPA2 client interoperation. Allow WPA-TKIP clients WPA2-CCMP Mixed Mode enables WPA2-CCMP and WPA-TKIP clients to operate together on the network. Enabling this option allows backwards compatibility for clients that support WPA-TKIP but do not support WPA2-CCMP. Symbol recommends enabling this feature if WPA-TKIP supported MUs operate within a WLAN populated by WPA2-CCMP enabled clients. Configuring Access Point Security 6-25 8. Configure the Fast Roaming (802.1x only) field as required to enable additional access point roaming and key caching options. This feature is applicable only when using 802.1x EAP authentication with WPA2/CCMP. Pre-Authentication Selecting this option enables an associated MU to carry out an 802.1x authentication with another access point before it roams to it. The access point caches the keying information of the client until it roams to the other access point. This enables the roaming client to start sending and receiving data sooner by not having to do 802.1x authentication after it roams. This feature is only supported when 802.1x EAP authentication is enabled. 9. Click the Apply button to save any changes made within the WPA2/CCMP Settings field of the New Security Policy screen. 10. Click the Cancel button to undo any changes made within the WPA2/CCMP Settings field and return to the WLAN screen. This reverts all settings to the last saved configuration. 6.10 Configuring Firewall Settings The access point's firewall is a set of related programs located in the gateway on the WAN side of the access point. The firewall uses a collection of filters to screen information packets for known types of system attacks. Some of the access point's filters are continuously enabled, others are configurable. Use the access points Firewall screen to enable or disable the configurable firewall filters. Enable each filter for maximum security. Disable a filter if the corresponding attack does not seem a threat in order to reduce processor overhead. Use the WLAN Security screens (WEP, Kerberos etc.) as required for setting user authentication and data encryption parameters. To configure the access point firewall settings:
1. Select Network Configuration -> Firewall from the access point menu tree. 6-26 AP-51xx Access Point Product Reference Guide 2. Refer to the Global Firewall Disable field to enable or disable the access point firewall. Disable Firewall Select the Disable Firewall checkbox to disable all firewall functions on the access point. This includes firewall filters, NAT, VPN, content filtering, and subnet access. Disabling the access point firewall makes the access point vulnerable to data attacks and is not recommended during normal operation if using the WAN port. 3. Refer to the Timeout Configuration field to define a timeout interval to terminate IP address translations. NAT Timeout Network Address Translation (NAT) converts an IP address in one network to a different IP address or set of IP addresses in a different network. Set a NAT Timeout interval (in minutes) the access point uses to terminate the IP address translation process if no translation activity is detected after the specified interval. 4. Refer to the Configurable Firewall Filters field to set the following firewall filters:
SYN Flood Attack Check A SYN flood attack requests a connection and then fails to promptly acknowledge a destination host's response, leaving the destination host vulnerable to a flood of connection requests. Configuring Access Point Security 6-27 Source Routing Check A source routing attack specifies an exact route for a packet's travel through a network, while exploiting the use of an intermediate host to gain access to a private host. Winnuke Attack Check A "Win-nuking" attack uses the IP address of a destination host to send junk packets to its receiving port. FTP Bounce Attack Check An FTP bounce attack uses the PORT command in FTP mode to gain access to arbitrary ports on machines other than the originating client. IP Unaligned Timestamp Check An IP unaligned timestamp attack uses a frame with the IP timestamp option, where the timestamp is not aligned on a 32-bit boundary. Sequence Number Prediction Check A sequence number prediction attack establishes a three-way TCP connection with a forged source address. The attacker guesses the sequence number of the destination host response. Mime Flood Attack Check Max Header Length Use the Max Header Length field to set the maximum allowable A MIME flood attack uses an improperly formatted MIME header in "sendmail" to cause a buffer overflow on the destination host. Max Headers header length (at least 256 bytes). Use the Max Headers field to set the maximum number of headers allowed (at least 12 headers). 5.

Use the Subnet Access screen to allow/deny access to the access point WAN protocols, specify names and properties for existing protocols and enable pre-configured protocols (FTP, TFTP, Telnet ect.). To configure access point subnet access:
6-28 AP-51xx Access Point Product Reference Guide 1. Select Network Configuration -> Firewall -> Subnet Access from the access point menu tree. 2. Refer to the Overview table to view rectangles representing subnet associations. The three possible colors indicate the current access level, as defined, for each subnet association. Color Access Type Description Green Yellow Full Access Limited Access Red No Access No protocol exceptions (rules) are specified. All traffic may pass between these two areas. One or more protocol rules are specified. Specific protocols are either enabled or disabled between these two areas. Click the table cell of interest and look at the exceptions area in the lower half of the screen to determine the protocols that are either allowed or denied. All protocols are denied, without exception. No traffic will pass between these two areas. 3. Configure the Rules field as required to allow or deny access to selected (enabled) protocols. Configuring Access Point Security 6-29 Allow or Deny all protocols, except Pre configured Rules Use the drop-down menu to select either Allow or Deny. The selected setting applies to all protocols except those with enabled checkboxes and any traffic that is added to the table. For example, if the adoption rule is to Deny access to all protocols except those listed, access is allowed only to those selected protocols. The following protocols are preconfigured with the access point. To enable a protocol, check the box next to the protocol name.
HTTP - Hypertext Transfer Protocol is the protocol for transferring files on the Web. HTTP is an application protocol running on top of the TCP/IP suite of protocols, the foundation protocols for the Internet. The HTTP protocol uses TCP port 80.
TELNET - TELNET is the terminal emulation protocol of TCP/
IP. TELNET uses TCP to achieve a virtual connection between server and client, then negotiates options on both sides of the connection. TELNET uses TCP port 23.
FTP - File Transfer Protocol (FTP) is an application protocol using the Internet's TCP/IP protocols. FTP provides an efficient way to exchange files between computers on the Internet. FTP uses TCP port 21.
SMTP - Simple Mail Transfer Protocol is a TCP/IP protocol for sending and receiving email. Due to its limited ability to queue messages at the receiving end, SMTP is often used with POP3 or IMAP. SMTP sends the email, and POP3 or IMAP receives the email. SMTP uses TCP port 25.
POP - Post Office Protocol is a TCP/IP protocol intended to permit a workstation to dynamically access a maildrop on a server host. A workstation uses POP3 to retrieve email that the server is holding for it.
DNS - Domain Name Service protocol searches for resources using a database distributed among different name servers. Add Del (Delete) Name Click Add to create a new table entry. Click Del (Delete) to remove a selected list entry. Specify a name for a newly configured protocol. 6-30 AP-51xx Access Point Product Reference Guide Transport Start Port End Port Select a protocol from the drop-down menu.

A prompt displays confirming the logout before the applet is closed. 6.10.1.1 Available Protocols Protocols that are not pre-configured can be specified using the drop down list within the Transport column within the Subnet Access and Advanced Subnet Access screens. They include:
ALL - Enables all of the protocol options displayed in the drop-down menu (as described below).
TCP - Transmission Control Protocol is a set of rules for sending data as message units over the Internet. TCP manages individual data packets. Messages are divided into packets for efficient routing through the Internet.
UDP - User Datagram Protocol is used for broadcasting data over the Internet. Like TCP, UDP runs on top of Internet Protocol (IP) networks. Unlike TCP/IP, UDP/IP provides few error recovery services. UDP offers a way to directly connect, and then send and receive datagrams over an IP network.
ICMP - Internet Control Message Protocol is tightly integrated with IP. ICMP messages are used for out-of-band messages related to network operation. ICMP packet delivery is unreliable. Hosts cannot count on receiving ICMP packets for a network problem.
AH - Authentication Header is one of the two key components of IP Security Protocol (IPsec). The other key component is Encapsulating Security Protocol (ESP). AH provides authentication, proving the packet sender really is the sender, and the data really is the data sent. AH can be used in transport mode, providing security between two Configuring Access Point Security 6-31 end points. Also, AH can be used in tunnel mode, providing security like that of a Virtual Private Network (VPN).
ESP - Encapsulating Security Protocol is one of two key components of IP Security Protocol
(IPsec). The other key component is Authentication Header (AH). ESP encrypts the packets and provides authentication services. ESP can be used in transport mode, providing security between two end points. ESP can also be used in tunnel mode, providing security like that of a Virtual Private Network (VPN).
GRE - General Routing Encapsulation supports VPNs across the Internet. GRE is a mechanism for encapsulating network layer protocols over any other network layer protocol. Such encapsulation allows routing of IP packets between private IP networks across an Internet using globally assigned IP addresses. 6.10.2 Configuring Advanced Subnet Access Use the Advanced Subnet Access screen to configure complex access rules and filtering based on source port, destination port, and transport protocol. To enable advanced subnet access, the subnet access rules must be overridden.

VPN tunnels allow all traffic on a local subnet to route securely through a IPSEC tunnel to a private network. A VPN port is a virtual port which handles tunneled traffic. When connecting to another site using a VPN, the traffic is encrypted so if anyone intercepts the traffic, they cannot see what it is unless they can break the encryption. The traffic is encrypted from your computer through the network to the VPN. At that point the traffic is decrypted. 6-34 AP-51xx Access Point Product Reference Guide Use the VPN screen to add and remove VPN tunnels. To configure an existing VPN tunnel, select it from the list in the VPN Tunnels field. The selected tunnels configuration displays in a VPN Tunnel Config field.

A rogue AP is a device located nearby an authorized Symbol access point but recognized as having properties rendering its operation illegal and threatening to the access point and the LAN. Rogue AP detection can be configured independently for both access point 802.11a and 802.11b/g radios (if using a dual radio sku access point). A rogue detection interval is the user-defined interval the access point waits to search for rogue APs. Additionally, the access point does not detect rogue APs on illegal channels (channels not allowed by the regulatory requirements of the country the access point is operating in). Configuring Access Point Security 6-53 The rogue detection interval is used in conjunction with Symbol MUs that identify themselves as rogue detection capable to the access point. The detection interval defines how often the access point requests these MUs to scan for a rogue AP. A shorter interval can effect the performance of the MU, but it will also decrease the time it takes for the access point to scan for a rogue AP. A longer interval will have less of an impact to the MUs, but it will increase the amount of time used to detect rogue APs. Therefore, the interval should be set according to the perceived risk of rogue devices and the criticality of MU performance.
!
CAUTION Using an antenna other than the Dual-Band Antenna (Part No. ML-2452-APA2-01) could render the access points Rogue AP Detector Mode feature inoperable. Contact your Symbol sales associate for specific information. To configure Rogue AP detection for the access point:
1. Select Network Configuration -> Wireless -> Rogue AP Detection from the access point menu tree. 2. Configure the Detection Method field to set the detection method (MU or access point) and define the 802.11a or 802.11b/g radio to conduct the rogue AP search. 6-54 AP-51xx Access Point Product Reference Guide RF Scan by MU RF On-Channel Detection RF Scan by Detector Radio Select the RF Scan by MU checkbox to enable MUs to scan for potential rogue APs within the network. Define an interval in the Scan Interval field for associated MUs to beacon in an attempt to locate a rogue AP. Set the interval to a value sooner than the default if a large volume of device network traffic is anticipated within the coverage area of the target access point access point.

PEAP - Select the PEAP checkbox to enable both PEAP types (GTC and MSCHAP-V2) available to the access point. PEAP uses a TLS layer on top of EAP as a carrier for other EAP modules. PEAP is an ideal choice for networks using legacy EAP authentication methods.
TTLS - Select the TTLS checkbox to enable all three TTLS types (MD5, PAP and MSCHAP-V2) available to the access point.TTLS is similar to EAP-TLS, but the client authentication portion of the protocol is not performed until after a secure transport tunnel is established. This allows EAP-TTLS to protect legacy authentication methods used by some RADIUS servers.
TLS - The TLS checkbox is selected but disabled by default and resides in the background as it does not contain user configurable parameters. Configuring Access Point Security 6-63 Default Authentication Type Server Certificate CA Certificate Specify a PEAP and/or TTLS Authentication Type for EAP to use from the drop-down menu to the right of each checkbox item. PEAP options include:
GTC - EAP Generic Token Card (GTC) is a challenge handshake authentication protocol using a hardware token card to provide the response string.
MSCHAP-V2 - Microsoft CHAP (MSCHAP-V2) is an encrypted authentication method based on Microsoft's challenge/
response authentication protocol. TTLS options include:
PAP - Password Authentication Protocol sends a username and password over a network to a server that compares the username and password to a table of authorized users. If the username and password are matched in the table, server access is authorized. WatchGuard products do not support the PAP protocol because the username and password are sent as clear text that a hacker can read.
MD5 - This option enables the MD5 algorithm for data verification. MD5 takes as input a message of arbitrary length and produces a 128- bit fingerprint. The MD5 algorithm is intended for digital signature applications, in which a large file must be compressed in a secure manner before being encrypted with a private (secret) key under a public-key cryptographic system.
MSCHAP-V2 - Microsoft CHAP (MSCHAP-V2) is an encrypted authentication method based on Microsoft's challenge/
response authentication protocol. If you have a server certificate from a CA and wish to use it on the Radius server, select it from the drop-down menu. Only certificates imported to the access point are available in the menu.For information on creating a certificate, see Creating Self Certificates for Accessing the VPN on page 4-10. You can also choose an imported CA Certificate to use on the Radius server. If using a server certificate signed by a CA, import that CA's root certificate using the CA certificates screen (for information, see Importing a CA Certificate on page 4-8). After a valid CA certificate has been imported, it is available from the CA Certificate drop-down menu. 6-64 AP-51xx Access Point Product Reference Guide 4.

Use this informatiaccess point on to determine whether this AP provides better MU association support than the locating access point or warrants consideration as a member of a different mesh network. 4. Click the Ping button to display a screen for verifying the link with a highlighted Symbol access point. NOTE A ping test initiated from the access point Known AP Statistics screen uses WNMP pings. Therefore, target devices that are not Symbol access points are unable to respond to the ping test. Monitoring Statistics 7-33 5. Click the Send Cfg to APs button to send the your access points configuration to other access points. The recipient access point must be the same single or dual-radio model as the access point sending the configuration. The sending and recipient access points must also be running the same major firmware version (i.e., 1.1 to 1.1).
!
CAUTION When using the Send Cfg to APs function to migrate an access points configuration to other access points, it is important to keep in mind mesh network configuration parameters do not get completely sent to other access points. The Send Cfg to APs function will not send the auto-select and preferred list settings. Additionally, LAN1 and LAN2 IP mode settings will only be sent if the senders AP mode is DHCP or BOOTP. The WANs IP mode will only be sent if the senders IP mode is DHCP. 6. Click the Start Flash button to flash the LEDs of other access points detected and displayed within the Known AP Statistics screen. Use the Start Flash button to determine the location of the devices displayed within the Known AP Statistics screen. When an access point is highlighted and the Start Flash button is selected, the LEDs on the selected access point flash. When the Stop Flash button is selected, the LEDs on the selected access point go back to normal operation. 7. Click the Logout button to securely exit the access point Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. 7-34 AP-51xx Access Point Product Reference Guide Command Line Interface Reference The access point Command Line Interface (CLI) is accessed through the serial port or a Telnet session. The access point CLI follows the same conventions as the Web-based user interface. The CLI does, however, provide an escape sequence to provide diagnostics for problem identification and resolution. The CLI treats the following as invalid characters:
| " & , \ ' < >
In order to avoid problems when using the CLI, these characters should be avoided. 8.1 Connecting to the CLI 8.1.1 Accessing the CLI through the Serial Port To connect to the access point CLI through the serial port:
1. Connect one end of a null modem serial cable to the access points serial connector. 2. Attach the other end of the null modem serial cable to the serial port of a PC running HyperTerminal or a similar emulation program. 3. Set the HyperTerminal program to use 19200 baud, 8 data bits, 1 stop bit, no parity, no flow 4. 5. control, and auto-detect for terminal emulation. Press <ESC> or <Enter> to enter into the CLI. Enter the default username of admin and the default password of symbol. If this is your first time logging into the access point, you are unable to access any of the access points commands until the country code is set. A new password will also need to be created. 8-2 AP-51xx Access Point Product Reference Guide 8.1.2 Accessing the CLI via Telnet To connect to the access point CLI through a Telnet connection:
1. 2. Telnet into the access point using an IP address of 192.168.0.1 Enter the default username of admin and the default password of symbol. If this is your first time logging into the access point, you are unable to access any of the access points commands until the country code is set. A new password will also need to be created.

The access point can be set to a client bridge mode and/or a base bridge mode (which accepts connections from client bridges). Base bridge and client bridge mode can be used at the same time by an individual access point to optimally bridge traffic to other members of the mesh network and service associated MUs. An access point in client bridge mode scans to locate other access points using the WLAP client's ESSID. Then it is required to go through the association and authentication process to establish wireless connections with the located devices. This association process is identical to the access points current MU association process. Once the association and authentication process is complete, the wireless client adds the connection as a port on its bridge module. This causes the client bridge to begin forwarding packets to the base bridge node. The base bridge realizes it is talking to a wireless client bridge. It then adds that connection as a port on its own bridge module. The two bridges at that point are communicating using the Spanning Tree Protocol (STP). 9-2 AP-51xx Access Point Product Reference Guide access points configured as both a base and a client bridge function as repeaters to transmit data with associated MUs in their coverage area (client bridge mode) as well as forward traffic to other access points in the mesh network (base bridge mode). The number of access points and their intended function within the mesh network dictate whether they should be configured as base bridges, client bridges or both (repeaters). For a use case on how access points are configured in respect to a fictional business need, see Usage Scenario - Trion Enterprises on page 9-19. The spanning tree determines the path to the root and detects if the current connection is part of a network loop with another connection in the system. Each bridge can be configurable so the administrator can control the spanning tree to define the root bridge and what the forwarding paths are. Once the spanning tree converges, both access points begin learning which destinations reside on which side of the network. This allows them to forward traffic intelligently. After the client bridge establishes at least one wireless connection (if configured to support mobile users), it begins beaconing and accepting wireless connections. If configured as both a client bridge and a base bridge, it begin accepting client bridge connections. Therefore, the mesh network could connect simultaneously to different networks in a manner whereby a network loop is not created and then the connection is not blocked. Once the client bridge establishes at least one wireless connection, it begins establishing other wireless connections as it finds them available. Thus, the client bridge is able to establish simultaneous redundant links. A mesh network must use one of the two access point LANs. If intending to use the access point for mesh networking support, Symbol recommends configuring at least one WLAN (of the 16 WLANs available) specifically for mesh networking support. The client bridge creates up to three connections if it can find base bridges for connection. If the connections are redundant (on the same network), then one connection will be forwarding and the others blocked. However, if each of the connections links to a different wired network, then none are redundant and all are forwarding. Thus, the bridge automatically detects and disables redundant connections, but leaves non-redundant connections forwarding. This gives the user the freedom to configure their topology in a variety of ways without limitations. This is important when configuring multiple access points for base bridge support in areas like a shipping yard where a large radio coverage area is required. For more information on configuring the access point in respect to specific usage scenarios, see Usage Scenario - Trion Enterprises on page 9-19. NOTE Since each access point can establish up to 3 simultaneous wireless connections, some of these connections could be redundant. If this is the case, the STP algorithm defines which links are the redundant links and disables those links from forwarding. Configuring Mesh Networking 9-3 If an access point is configured as a base bridge (but not as a client bridge) it operates normally at boot time. The base bridge supports connections made by other client bridges. The dual-radio model access point affords users better optimization of the mesh networking feature by enabling the access point to transmit to other mesh network members using one independent radio and transmit with associated MUs using the second independent radio. A single-radio access point has its channel utilization and throughput degraded in a mesh network, as the APs single radio must process both mesh network traffic with other access points and MU traffic with its associated devices.
!
CAUTION Only Symbol AP-5131 or AP-5181 model access points can be used as base bridges, client bridges or repeaters within an access point supported mesh network. If utilizing a mesh network, Symbol recommends considering a dual-radio model to optimize channel utilization and throughput. 9.1.1 The AP-51xx Client Bridge Association Process An access point in client bridge mode performs an active scan to quickly create a table of the access points nearby. The table contains the access points matching the ESS of the client bridge APs WLAN. The table is used to determine the best access point to connect to (based on signal strength, load and the user's configured preferred connection list). The association and authentication process is identical to the MU association process. The client access point sends 802.11 authentication and association frames to the base access point. The base access point responds as if the client is an actual mobile unit. Depending on the security policy, the two access points engage in the normal handshake mechanism to establish keys. After device association, the two access points are connected and the system can establish the bridge and run the spanning tree algorithm. In the meantime, the access point in client bridge mode continues to scan in the background attempts to establish an association with other access points using the same ESS on the same channel.
!
CAUTION An access point is Base Bridge mode logs out whenever a Client Bridge associates to the Base Bridge over the LAN connection. This problem is not experienced over the access points WAN connection. If this situation is experienced, log-in to the access point again. 9-4 AP-51xx Access Point Product Reference Guide The access point in client bridge mode attempts to establish up to 3 simultaneous wireless connections. The second and third connections are established in the background while the system is running. The first connection needs to be established before the system starts bridging traffic. The dual-radio model access point affords users better optimization of the mesh networking feature by allowing the access point to transmit to other access points (in base or client bridge mode) using one independent radio and transmit with its associated MUs using the second independent radio. A single-radio access point has its channel utilization and throughput degraded in a mesh network, as the access points single radio must process both mesh network traffic with other access points and MU traffic with its associated devices. 9.1.2 Spanning Tree Protocol (STP) The access point performs mesh networking using STP as defined in the 802.1d standard. NOTE The Symbol AP-4131 access point uses a non-standard form of 802.1d STP, and is therefore not compatible as a base bridge or client bridge within an access point managed network. Once device association is complete, the client and base bridge exchange Configuration Bridge Protocol Data Units (BPDUs) to determine the path to the root. STP also determines whether a given port is a redundant connection or not. 9.1.3 Defining the Mesh Topology When a user wants to control how the spanning tree determines client bridge connections, they need to control the mesh configuration. The user must be able to define one node as the root. Assigning a base bridge the lowest bridge priority defines it as the root. NOTE Symbol recommends using the Mesh STP Configuration screen to define a base bridge as a root. Only advanced users should use the Advanced Client Bridge Settings screens Preferred List to define the mesh topology, as omitting a bridge from the preferred list could break connections within the mesh network. The access point can manipulate the path cost assigned to a bridge connection based on that connections RSSI. This results in the spanning tree selecting the optimal path for forwarding data when redundant paths exist. However, this can be overridden using the preferred list. When using the Configuring Mesh Networking 9-5 preferred list, the user enters a priority for each bridge, resulting in the selection of the forwarding link. Limit the wireless clients connections to reduce the number of hops required to get to the wired network. Use each radios "preferred" base bridge list to define which access points the client bridge connects to. For more information, see Configuring Mesh Networking Support on page 9-6. 9.1.4 Mesh Networking and the AP-51xxs Two Subnets The access point now has a second subnet on the LAN side of the system. This means wireless clients communicating through the same radio can reside on different subnets. The addition of this feature adds another layer of complexity to the access points mesh networking functionality. With a second LAN introduced, the LANs Ethernet port (and any of the 16 WLANs) could be assigned to one of two different subnets. From a layer 2 perspective, the system has two different bridge functionalities, each with its own STP. The WLAN assignment controls the subnet (LAN1 or 2) upon which a given connection resides. If WLAN2 is assigned to LAN1, and WLAN2 is used to establish a client bridge connection, then the mesh network connection resides on LAN1. Therefore, (depending upon the WLAN-to-LAN mapping), the access point could have multiple mesh connections on either LAN1 or LAN2. 9.1.5 Normal Operation Once the mesh network is defined, all normal access point operations are still allowed. MUs are still allowed to associate with the access point as usual. The user can create WLANs, security polices and VLANs as with any other access point. DHCP services function normally and all layer 3 communications are allowed. WNMP is used to send information about each mesh network so information can be displayed to the user from any access point on the system. WNMP messages are AP-AP info messages used to send system status. 9.1.6 Impact of Importing/Exporting Configurations to a Mesh Network When using the access points Configuration Import/Export screen to migrate an access points configuration to other access points, mesh network configuration parameters will get sent or saved 9-6 AP-51xx Access Point Product Reference Guide to other access points. However, if using the Known AP Statistics screens Send Cfg to APs functionality, auto-select and preferred list settings do not get imported.
!
CAUTION When using the Import/Export screen to import a mesh supported configuration, do not import a base bridge configuration into an existing client bridge, as this could cause the mesh configuration to break. 9.2 Configuring Mesh Networking Support Configuring the access point for Mesh Bridging support entails:
Setting the LAN Configuration for Mesh Networking Support
Configuring a WLAN for Mesh Networking Support
Configuring the Access Point Radio for Mesh Support. 9.2.1 Setting the LAN Configuration for Mesh Networking Support At least one of the two access point LANs needs to be enabled and have a mesh configuration defined to correctly function as a base or client bridge within a mesh network. This section describes the configuration activities required to define a mesh networks LAN configuration. As the Spanning Tree Protocol (STP) mentions, each mesh network maintains hello, forward delay and max age timers. The base bridge defined as the root imposes these settings within the mesh network. The user does not necessarily have to change these settings, as the default settings will work. However, Symbol encourages the user to define an access point as a base bridge and root (using the base bridge priority settings within the Bridge STP Configuration screen). Members of the mesh network can be configured as client bridges or additional base bridges with a higher priority value. NOTE For an overview on mesh networking and some of the implications on using the feature with the access point, see Configuring Mesh Networking on page 9-1. To define a LANs Mesh STP Configuration:
1. 2. Select Network Configuration -> LAN from the AP-5131 menu tree. Enable the LAN used to support the mesh network. Configuring Mesh Networking 9-7 3. Verify the enabled LAN is named appropriately in respect to its intended function in supporting the mesh network. Select Network Configuration -> LAN -> LAN1 or LAN2 from the AP-5131 menu tree. Click the Mesh STP Configuration button on the bottom off the screen. 4. 5. Define the properties for the following parameters within the mesh network:
Priority Maximum Message age Set the Priority as low as possible for a to force other devices within the mesh network to defer to this client bridge as the bridge defining the mesh configuration (commonly referred to as the root). Symbol recommends assigning a Base Bridge AP with the lowest bridge priority so it becomes the root in the STP. If a root already exists, set the Bridge Priorities of new APs accordingly so the root of the STP doesn't get altered. Each access point starts with a default bridge priority of 32768. The Maximum Message age timer is used with the Message Age timer. The Message Age timer is used to measure the age of the received protocol information recorded for a port, and to ensure the information is discarded when it exceeds the value set for the Maximum Message age timer. 9-8 AP-51xx Access Point Product Reference Guide Hello Time Forward Delay Forwarding Table Ageout The Hello Time is the time between each bridge protocol data unit sent. This time is equal to 2 seconds (sec) by default, but you can tune the time to be between 1 and 10 sec. If you drop the hello time from 2 sec to 1 sec, you double the number of bridge protocol data units sent/received by each bridge. The 802.1d specification recommends the Hello Time be set to a value less than half of the Max Message age value. The Forward Delay is the time spent in the listening and learning state. This time is equal to 15 sec by default, but you can tune the time to be between 4 and 30 sec. The 802.1d specification recommends the Forward Delay be set to a value greater than half the Max Message age timeout value. The Forwarding Table Parameter value defines the length of time an entry will remain in the a bridges forwarding table before being deleted due to lack of activity. If the entry replenishments a destination generating continuous traffic, this timeout value will never be invoked. However, if the destination becomes idle, the timeout value represents the length of time that must be exceeded before an entry is deleted from the forwarding table. 6. 7. Click OK to return to either the LAN1 or LAN2 screen where updates to the Mesh STP Configuration can be saved by clicking the Apply button. Click Cancel to discard the changes made to the Mesh STP Configuration and return to the LAN1 or LAN2 screen. Once the Mesh STP Configuration is defined, the access points radio can be configured for base and/or client bridge support. 9.2.2 Configuring a WLAN for Mesh Networking Support Each access point comprising a particular mesh network is required to be a member of the same WLAN. Therefore, each base bridge, client bridge or repeater within the mesh network must use the same WLAN in order to share the same ESSID, radio designation, security policy, MU ACL and Quality of Service policy. If intending to use the access point for mesh networking support, Symbol recommends configuring at least one WLAN (of the 16 WLANs available) specifically for mesh networking support. To define the attributes of the WLAN shared by the members of the mesh network:
1. Select Network Configuration -> Wireless from the AP-5131 menu tree. Configuring Mesh Networking 9-9 The Wireless Configuration screen displays with those existing WLANs displayed within the table. 2. Select the Create button to configure a new WLAN specifically to support mesh networking. An existing WLAN can be modified (or used as is) for mesh networking support by selecting it from the list of available WLANs and clicking the Edit button. 3. Assign an ESSID and Name to the WLAN that each access point will share when using this WLAN within their mesh network. 9-10 AP-51xx Access Point Product Reference Guide Symbol recommends assigning a unique name to a WLAN supporting a mesh network to differentiate it from WLANs defined for non mesh support. The name assigned to the WLAN is what is selected from the Radio Configuration screen for use within the mesh network. NOTE It is possible to have different ESSID and WLAN assignments within a single mesh network (one set between the Base Bridge and repeater and another between the repeater and Client Bridge). However, for ease of management and to not waste network bandwidth, Symbol recommends using the same ESSID across the entire mesh network. 4. Use the Available On checkboxes to specify the access point radio(s) used with the target WLAN within the mesh network. The Available On checkboxes are for making this WLAN available for base bridges or repeaters to connect to. The Available On checkbox should only be selected for a mesh WLAN if this target access point is to be configured as a base bridge or repeater on the radio. If the WLAN is to be defined for client bridge support only, the Available On checkbox should not be selected. Instead, it only needs to have the Enable Client Bridge Backhaul option selected. 6. 5. Use the Maximum MUs field to define the number of MUs allowed to associate with this WLAN. This number should be defined based on the number of client bridge and repeaters within this mesh network. This value can be increased as the mesh network grows and devices are added. Only advanced users should define the number of devices allowed to associate with the WLAN, as setting the value too low could restrict devices from joining an expanding mesh network, and setting it too high could prohibit other WLANs from granting access to the all the devices needed. Select the Enable Client Bridge Backhaul checkbox to make this WLAN available in the Mesh Network Name drop-down menu within the Radio Configuration screen. Only WLANs defined for mesh networking support should have this checkbox selected, in order to keep the list of WLANs available (within the Radio Configuration screen) restricted to just WLANs configured specifically with mesh attributes. Refer to the Security Policy drop-down menu to select the security policy used within this WLAN and mesh network. A security policy for a mesh network should be configured carefully since the data protection requirements within a mesh network differ somewhat compared to a typical wireless LAN. No Encryption is a bad idea in a mesh network, since mesh networks 7. Configuring Mesh Networking 9-11 are typically not guest networks, wherein public assess is more important than data protection. Symbol also discourages user-based authentication schemes such as Kerberos and 802.1x EAP, as these authentication schemes are not supported within a mesh network. If none of the existing policies are suitable, select the Create button to the right of the Security Policy drop-down menu and configure a policy suitable for the mesh network. For information on configuring a security using the authentication and encryption techniques available to the access point, see Enabling Authentication and Encryption Schemes on page 6-5. 8. ACL policies should be configured to allow or deny a range of MAC addresses from interoperating with the WLAN used with the mesh network. ACLs should be defined based on the client bridge and repeater (an access point defined as both a base and client bridge) association requirements within the mesh network. For information on defining an ACL for use with the WLAN assigned to the mesh network, see Configuring a WLAN Access Control List (ACL) on page 5-30. NOTE The Kerberos User Name and Kerberos Password fields can be ignored, as Kerberos is not supported as a viable authentication scheme within a mesh network. 9. Select the Disallow MU to MU Communication checkbox to restrict MUs from interacting with each other both within this WLAN, as well as other WLANs. Selecting this option could be a good idea, if restricting device chatter improves mesh network performance. If base bridges and client bridges are added at any given time to extent the coverage are of a mesh network, the data going back and forth amongst just those radios could be compromised by network interference. Adding mesh device traffic could jeopardize network throughput. If however, MU to MU communication is central to the organization (for example, scanners sharing data entry information) then this checkbox should remain unselected. 9-12 AP-51xx Access Point Product Reference Guide 10. Select the Use Secure Beacon checkbox to not transmit the AP- 5131s ESSID amongst the access points and devices within the mesh network. If a hacker tries to find an ESSID via an MU, the AP- 5131s ESSID does not display since the ESSID is not in the beacon. Symbol recommends keeping the option enabled to reduce the likelihood of hacking into the WLAN. 11. Select the Accept Broadcast ESSID checkbox to associate an MU that has a blank ESSID (regardless of which ESSID the access point is currently using). Traffic within a mesh network probably consists of known devices, so you may want to leave the checkbox unselected and configure each MU with an ESSID. The default is selected. However, for WLANs used within a mesh network, Symbol recommends unselecting this option as it would prevent the AP from answering to blank ESSID probes from other mobile units. If there are certain requirements for the types of data proliferating the mesh network, select an existing policy or configure a new QoS policy best suiting the requirements of the mesh network. To define a new QoS policy, select the Create button to the right of the Quality Of Service Policy drop-down menu. For detailed information on configuring a QoS policy, see Setting the WLAN Quality of Service (QoS) Policy on page 5-33. 12. 13. Click Apply to save the changes made to the mesh network configured WLAN. An access point radio is now ready to be configured for use with this newly created mesh WLAN. 9.2.3 Configuring the Access Point Radio for Mesh Support An access point radio intended for use within a mesh network requires configuration attributes unique from a radio intended for non-mesh support.This section describes how to configure an access point radio for mesh network support. Configuring Mesh Networking 9-13 To configure the access point radio for mesh networking support:
NOTE The dual-radio model access point affords users better optimization of the mesh network feature by allowing the access point to transmit to other access points (in base or client bridge mode) using one independent radio and transmit with its associated devices using the second independent radio. A single-radio access point has its channel utilization and throughput degraded in a mesh network, as the APs single radio must process both mesh network traffic with other access points and MU traffic with its associated devices. 1. Select Network Configuration -> Wireless -> Radio Configuration from the AP-5131 menu tree. 2.
!
Enable the radio(s) using the Enable checkbox(es) for both Radio 1 and Radio 2. Refer to RF Band of Operation parameter to ensure you are enabling the correct 802.11a or 802.11b/g radio. After the settings are applied within this Radio Configuration screen, the Radio Status and MUs connected values update. If this is an existing radio within a mesh network, these values update in real-time. CAUTION If a radio is disabled, be careful not to accidentally configure a new WLAN, expecting the radio to be operating when you have forgotten it was disabled. 9-14 AP-51xx Access Point Product Reference Guide 3. Select the Base Bridge checkbox to allow the access point radio to accept client bridge connections from other access points in client bridge mode. The base bridge is the acceptor of mesh network data from those client bridges within the mesh network and never the initiator.

4.
!
CAUTION A problem could arise if a Base Bridges Indoor channel is not available on an Outdoor Client Bridge's list of available channels. As long as an Outdoor Client Bridge has the Indoor Base Bridge channel in its available list of channels, it can associate to the Base Bridge. If the Base Bridge checkbox has been selected, use the Max# Client Bridges parameter to define the client bridge load on a particular base bridge. The maximum number of client bridge connections per access point radio is 12, with 24 representing the maximum for dual-radio models. CAUTION An access point in Base Bridge mode logs out whenever a Client Bridge associates to the Base Bridge over the LAN connection. This problem is not experienced over the access points WAN connection. If this situation is experienced, log-in to the access point again. Once the settings within the Radio Configuration screen are applied (for an initial deployment), the current number of client bridge connections for this specific radio displays within the CBs Connected field. If this is an existing radio within a mesh network, this value updates in real-time. 5. Select the Client Bridge checkbox to enable the access point radio to initiate client bridge connections with other mesh network supported access points radios on the same WLAN. Configuring Mesh Networking 9-15 If the Client Bridge checkbox has been selected, use the Mesh Network Name drop-down menu to select the WLAN (ESS) the client bridge uses to establish a wireless link. The default setting, is (WLAN1). Symbol recommends creating (and naming) a WLAN specifically for mesh networking support to differentiate the Mesh supported WLAN from non-Mesh supported WLANs. For more information, see Configuring a WLAN for Mesh Networking Support on page 9-8 Once the settings within the Radio Configuration screen are applied (for an initial deployment), the current number of base bridges visible to the radio displays within the BBs Visible field, and the number of base bridges currently connected to the radio displays within the BBs Connected field. If this is an existing radio within a mesh network, these values update in real-time. NOTE Ensure you have verified the radio configuration for both Radio 1 and Radio 2 before saving the existing settings and exiting the Radio Configuration screen.v 6. Click the Advanced button to define a prioritized list of access points to define mesh connection links. 7. Select the Automatic Link Selection checkbox to allow the access point to select the links used by the client bridge to populate the mesh network. Selecting this checkbox prohibits 9-16 AP-51xx Access Point Product Reference Guide the user from selecting the order base bridges are added to the mesh network when one of the three associated base bridges becomes unavailable. NOTE Auto link selection is based on the RSSI and load. The client bridge will select the best available link when the Automatic Link Selection checkbox is selected. Symbol recommends you do not disable this option, as (when enabled) the access point will select the best base bridge for connection. 8. Refer to the Available Base Bridge List to view devices located by the access point using the WLAN selected from the Radio Configuration screen. Refer the following for information on located base bridges:
MAC The MAC field displays the factory set hard-coded MAC address that serves as a device identifier. RSSI CHANN The Relative Signal Strength Indicator (RSSI) displays the located devices signal strength with the associated access point in client bridge mode. Use this information as criteria on whether to move a particular device from the available list to the preferred list. The CHANN displays the name of the channel that both the access point and base bridge use. A client bridge can only connect to access points (Base Bridges) on the same channel. If the user selects multiple base bridges on different channels, the access point will only be able to connect to those bridges on the same channel and the others will not be able to join this particular mesh network. 9. Click Refresh at any time to update the list of available Base Bridge devices available to the access point. 10. Use the >> button to move a selected base bridge MAC address from Available Base Bridge List 11. Refer to the Preferred Base Bridge List for a prioritized list of base bridges the mesh networks client bridge uses to extend the mesh networks coverage area and potentially provide redundant links. If a device does not appear on the Available Base Bridge List, there is no" way it can be moved to Preferred Base Bridge List as the device has not yet been
"seen." However, if you know the MAC Address corresponding to that Base Bridge, you can add that to the Preferred List using the add button. Configuring Mesh Networking 9-17 12. Highlight a MAC address from the Preferred Base Bridge List and click the Up button to assign that devices MAC address a higher priority and a greater likelihood of joining the mesh network if an association with another device is lost. If a MAC address is not desirable as others but still worthy of being on the preferred list, select it, and click the Down button to decrease its likelihood of being selected as a member of the mesh network. If a device MAC address is on the Preferred Base Bridge List and constitutes a threat as a potential member of the mesh network (poor RSSI etc.), select it and click the Remove button to exclude it from the preferred list. If all of the members of the Preferred Base Bridge List constitute a risk as a member of the mesh network, click the Remove All button. This is not recommended unless the preferred list can be re-populated with more desirable device MAC addresses from the Available Base Bridge List. 13. 14. Click Ok to return to the Radio Configuration screen. Within the Radio Configuration screen, click Apply to save any changes made within the Advanced Client Bridge Settings screen. 15. Click Cancel to undo any changes made within the Advanced Client Bridge Settings screen. This reverts all settings for the screen to the last saved configuration. 16. Click Apply to save any changes to the Radio Configuration screen. Navigating away from the screen without clicking Apply results in all changes to the screens being lost. CAUTION When defining a Mesh configuration and changes are saved, the
!
mesh network temporarily goes down. The mesh network is unavailable because the access point radio goes down when applying the changes. This can be problematic for users making changes within a deployed mesh network. If updating the mesh network using a LAN connection, the access point applet loses connection and the connection must be re-instated. If updating the mesh network using a WAN connection, the access point applet does not lose connection, but the mesh network is unavailable until the changes have been applied. 17. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on the Radio Configuration screen to the last saved configuration. 18. Click Logout to securely exit the AP-5131 Symbol Access Point applet. A prompt displays confirming the logout before the applet is closed. Once the target radio has been enabled from the Radio Configuration screen, configure the radios properties by selecting it from the AP-5131 menu tree. 9-18 AP-51xx Access Point Product Reference Guide For additional information on configuring the access points radio, see Configuring the 802.11a or 802.11b/g Radio on page 5-47. For fictional use case involving an access point mesh network deployment within a shipping and receiving yard, see Usage Scenario - Trion Enterprises on page 9-19. Configuring Mesh Networking 9-19 9.3 Usage Scenario - Trion Enterprises Trion Enterprises is a new shipping and receiving company. Trion wants to create an outdoor wireless coverage area (in addition to its indoor wireless infrastructure) that can expand as they grow their business. As Trion expands the wireless coverage area within their shipping yard, they will need additional access points configured as either base or client bridges or repeaters (access points configured as both base and client bridges) to support the growing number of MUs, and forward data traffic to the client bridges on the outer areas of the mesh network. The MUs within the shipping and receiving area consist primarily of Symbol bar code scanners (to monitor Trions inventory coming and going) as well as PDAs doing data entry. NOTE The information presented within this use case is centered around the configuration of the mesh networking feature exclusively. It is assumed the access points used by Trion Enterprises are completely configured
(beyond the mesh networking functionality) before being deployed in their shipping yard. 9.3.1 Trions Initial Deployment Trions initial requirement is to configure a point-to-point mesh network consisting of two access points (AP1 and AP2). AP1 is to be physically connected to a pole inside the entrance to the shipping and receiving area with antennas oriented outward into the shipping yard. AP1 is intended to be a base bridge with no coverage for MUs within the shipping yard. AP2 is intended to be a client bridge associated to AP1 and be placed on a wall of a receiving shack (a remote building in the shipping yard) with antennas oriented into the shipping yard. AP2 also is also connected to a Symbol ES3000 wireless switch providing connectivity (on its own local subnet) to laptops within the receiving shack. AP1 and AP2 will be configured identically unless noted. NOTE To optimize Trions mesh network, the IT team decides to create a mesh WLAN to strictly support the base bridge, client bridge and repeater traffic within the mesh network. This is the configuration described in this use case. However, to optimally support the MU traffic within the shipping yard, the Trion team should create a separate (non-mesh) WLAN to support the MU traffic proliferating the shipping yard. To configure the separate (non mesh) WLAN, the IT team follows the instructions in Creating/Editing Individual WLANs on page 5-24. To configure Trions initial deployment, the IT Team does the following:
9-20 AP-51xx Access Point Product Reference Guide 1. 2. The Trion IT department verifies connectivity with both of the access points following the instructions in Testing Connectivity on page 3-11. The Trion IT Department installs the AP1 on a wall with the antennas orienting outward into the shipping and receiving yard. The team then installs the AP2 on a wall on the receiving shack in the shipping yard. AP1 AP2 The Trion IT department follows the instructions in Wall Mounted Installations on page 2-14 to install AP1 and AP2. The Trion IT department selects Network Configuration -> LAN from the AP-5131 menu tree. 3. Configuring Mesh Networking 9-21 4. The Trion IT department verifies the LAN used to support the mesh network is enabled for both AP1 and AP2, (by selecting the Enable checkbox). NOTE In this fictional mesh network deployment for Trion Enterprises, AP1 and AP2 should both have the access points Ethernet Port mapped to the mesh LAN. However, there are some scenarios when this is not necessary. For example, when the Ethernet is not connected, or is being used for some other purpose such as routing traffic to the WAN connection. 5. 6. The Trion IT department then selects Network Configuration -> LAN -> trion from the AP-5131 menu tree. The IT team selects the Mesh STP Configuration button on the bottom off the screen. 7. The Trion IT department sets the Priority setting to 1 (for AP1) in order for future members of the mesh network to defer to AP1 as the AP defining the mesh network configuration
(setting this value to 1 AP1 to what is commonly referred to as the root). NOTE AP1 and AP2 have been configured identically up to this point. However, only AP1 is assigned a priority of 1 within the Bridge STP Configuration screen. AP2 is set to a lower priority (100) to keep AP1 as the root. The IT team leaves the Maximum Message age timer at the 20 sec default interval. This setting controls the maximum length of time that passes before a bridge port saves its configuration information. The Hello Time (the time between each bridge protocol data unit sent) is also unchanged from 2 second default interval. The IT team also leaves the Forward Delay (the time the access point LAN is spent in a listening and learning state) to the factory 9-22 AP-51xx Access Point Product Reference Guide 8. default of 15 seconds. Since only one additional access point is to be added to this point-to-
point mesh network, the Forwarding Table Ageout value is also unchanged from its 100 second default setting. The team clicks OK from within the Bridge STP Configuration screen and Apply from within the trion (LAN1) screen to save the settings. This step is repeated for AP2. The Trion IT team now intends to create a WLAN (to use with the trion LAN) that can be dedicated to their mesh network within the shipping yard. 9. Select Network Configuration -> Wireless from the AP-5131 menu tree. The Wireless Configuration screen displays with those existing WLANs displayed within the table. This is Trions first deployment for this new dual-radio access point, upon reviewing the Wireless Page they determine the existing default WLAN should be left as is and a new WLAN should be created that can be dedicated to the mesh network supporting the shipping yard. Configuring Mesh Networking 9-23 10. The team selects the Edit button to revise (and rename) the existing WLAN specifically to support mesh networking. 11. The Trion IT team assigns the WLAN a unique ESSID (103) used by each new base bridge, client bridge and repeater joining the mesh network. 12. The team assigns the name of trion mesh to the WLAN so it will not be confused with other WLANs used in other areas of the Trion facility. This name also serves to associate the name of the WLAN with its intended mesh network utilization of data. entry within the shipping yard 9-24 AP-51xx Access Point Product Reference Guide 13. For AP1 the team selects the 802.11a checkbox. Enabling the 802.11a radio for the mesh WLAN and configuring a separate WLAN for MU traffic (using the 802.11b/g radio), allows the team the best channel utilization and throughput available since the 802.11a radio can be dedicated strictly to communications within the mesh network and the 802.11b/g radio can be dedicated to servicing the 802.11b/g MUs supporting the shipping and receiving yard. For AP2, neither the 802.11a or 802.11b/g checkboxes are selected (see the screen displayed above). Only the Enable Client Bridge Backhaul checkbox needs to be selected for AP2 (as AP2 will be used as a client bridge). 14. The team does not want any MUs connecting to the mesh WLAN, only the client bridges comprising the mesh network. Therefore, the team leaves the Maximum MUs field as is, and will use the Radio Configuration page to control the number of client bridge connections. 15. The team verifies the Enable Client Bridge Backhaul checkbox is selected for AP2 to ensure the WLAN is available in the Mesh Network Name drop-down menu. Unlike the user-based Kerberos authentication scheme used within the Trion Administrative office and the 802.1x EAP scheme used in the Finance department, the IT Team wants to configure a security scheme for the WLAN that emphasizes security for the data proliferating the shipping yard, not its user base, as users may come and go whereas the data traffic within the shipping yard remains continuous. 16. The IT Team selects the Create button to the right of the Security Policy drop-down menu. The New Security Policy screen displays with no authentication or encryption options selected. 17. The IT Team selects the WPA2/CCMP radio button. The WPA2/CCMP Settings field displays within the New Security Policy screen. 18. The IT Team assigns a name of WPA2 mesh network to not only define the security scheme used, but associate this policy with its intended use for the shipping and receiving mesh network. Configuring Mesh Networking 9-25 19. The Broadcast Key Rotation checkbox is selected, as the IT team plans to change the keys from time to time (for security purposes) and wants these keys to be broadcasted using the default interval 86400 seconds. 20. The IT team does not want to use a passphrase to represent the 256-bit keys, so the 256-
bit Key checkbox is selected, and the team enters 16 hexadecimal characters into each of the four fields displayed. Once completed the Apply button is selected and the access point applet returns to the WLAN screen. 21. The team leaves the Allow WPA-TKIP clients and Pre-Authentication checkboxes unselected. Since the Trion Shipping and Receiving yard is considered a secure wireless network with MU traffic comprised of known 802.11b/g MUs with fixed MAC addresses, the IT team wants to create an ACL that excludes all MU traffic except the known range of Trion Enterprises deployed MAC addresses. 22. From back at the Edit WLAN screen, the IT team selects the Create button (to the right of the MU Access Control drop-down menu. The New MU ACL Policy screen displays with no existing MAC address ranges. 9-26 AP-51xx Access Point Product Reference Guide 23. The IT team assigns the name of trion mesh network to the ACL to eliminate any confusion with the ACLs intended function 24. Since the range of client bridge MAC addresses for the shipping yard mesh network is known to the IT Team, they select the Deny drop-down menu option, as the team wants to deny access to all MAC addresses except their own known range of device MAC addresses. 25. The IT team then selects the Add button and enters the base bridge MAC address that will be granted access to the access point managed WLAN. Once completed, the Apply button is selected and the access point applet returns to the WLAN screen. NOTE If the Trion IT team puts the client bridge addresses into the ACL, they should also put the access points BSS ID into the ACL since there is no way to know ahead of time which BSS the client bridge will use for association. Now a QoS policy needs to be defined for the shipping and receiving mesh network WLAN. The IT Team envisions little if any video or voice traffic within the shipping yard as the MUs within primarily scan bar codes and upload data. Configuring Mesh Networking 9-27 26. The team decides to leave the Disallow MU to MU Communication checkbox unselected for the WLAN, as the team considers all MU traffic within the secure shipping and receiving yard known and not a threat to the initial 2 AP mesh network deployment. 27. The team selects the Use Secure Beacon checkbox from the Edit WLAN screen to not transmit the AP- 5131s ESSID between AP1 and AP2. If a hacker tries to find an ESSID via an MU, the AP- 5131s ESSID does not display since the ESSID is not in the beacon. 28. The team does not select the Accept Broadcast ESSID checkbox from the Edit WLAN screen to associate MUs with a blank ESSID, as they do not want MUs randomly joining their carefully constructed mesh network. 29. From the Edit WLAN screen, the IT Team selects the Create button to the right of the Quality Of Service Policy drop-down menu. The New QoS Policy screen displays with no values selected. 30. The IT Team assigns the name of mesh network qos to the QoS policy to eliminate any confusion with the policys intended function. 9-28 AP-51xx Access Point Product Reference Guide 31. The IT Team does not plan on supporting any legacy 802.11b voice enabled devices, so they leave the Support Voice prioritization checkbox unselected. 32. The IT Team selects 11ag-default from the drop-down menu to best describe the type of data proliferating the mesh network. With this setting selected, the Access Category settings do not need to be configured for the QoS policy. 33. The IT Team selects the Enable Wi-Fi Multimedia (WMM) QoS Extensions checkbox, and selects the 11ag-default setting for the intended traffic within the WLAN. If multimedia or voice traffic would have proliferated the WLAN, the team would have selected 11ag-wifi or 11ag-voice. However, since simple data transfers are planned, the 11ag-default setting is appropriate. 34. The IT Team clicks Apply within both the New QoS Policy and Edit WLAN screen to save the settings to the mesh network WLAN. The configuration process is repeated and saved for AP2. The WLAN configuration has now been set similarly for both AP1 and AP2 (with the exception of the Priority setting within the Mesh STP Configuration screen). The team now needs to define the radio configuration for both AP1 and AP2. 35. The IT team selects Network Configuration -> Wireless -> Radio Configuration from the AP-5131 menu tree. The Radio Configuration screen displays. 36. For AP1, the IT Team enables both Radio 1 and Radio 2 and defines radio 1 as a base bridge. AP1 is intended to pass along mesh network data to AP2 (as well as other access points as they are added to the mesh network). Configuring Mesh Networking 9-29 37. For AP2, the IT Team enables both Radio 1 and Radio 2 and defines radio 1 as a client bridge. NOTE The Trion IT team is aware it is not a good idea to dedicate both radios (of a dual-radio model access point) to support mesh networking. They know it is possible to dedicate both radios of a single access point for mesh support, but the Trion team wants to dedicate the 802.11b/g radio for MU operation and the 802.11a radio for backhaul support. For AP2, the Trion team will create two connections to AP1 (one over the 802.11b/g radio and one over the 802.11a radio). The connection used for forwarding data for AP2 will be the 802.11b/g radio and the 802.11a radio will be dedicated for client bridge backhaul. 38. The IT Team leaves each radios Max # Client Bridge setting at the default setting of 12. This ensures as client bridges are added to the growing mesh network they can be accounted for. 39. For AP1 and AP2, the IT Team uses the Mesh Network Name drop-down menu to assign the trion mesh WLAN to the radio 1 client bridge. This is the WLAN the AP1 and AP2 radios will use to interoperate with the mesh network devices populating the shipping yard. 40. The IT Team decides to not select the Advanced button within the AP1 and AP2 WLAP Client Bridge Settings field. For the next six months, Trion Enterprises mesh network only consists of AP1 and AP2. AP1 has already been defined as the root bridge in the mesh network when it was assigned a Priority value of 1 within the Bridge STP Configuration screen. 9-30 AP-51xx Access Point Product Reference Guide 41. The Trion IT Team clicks Apply within both the AP1 and AP2 Radio Configuration screens to complete the mesh network configuration of each AP1 and AP2 radio. The team does not worry about network disruption by applying the settings at this point, as AP1 and AP2 have not yet been deployed. However, in the future they are aware saving their mesh configuration will temporarily disrupt service within their mesh network. NOTE With the mesh network configuration completed for AP1 and AP2, the Trion Enterprises IT team completes the configuration of the APs following the instructions in this access point Product Reference Guide. Later in the year Trion expects to grow their business to the point where 2 new client bridges are required to provide mesh networking to new areas of their shipping year. See, Adding 2 Client Bridges to Expand the Coverage Area on page 9-30. 9.3.2 Adding 2 Client Bridges to Expand the Coverage Area After a prosperous six months with their existing 2 access point mesh network, Trion Enterprises needs and approves the addition of two additional access points (AP3 and AP4) to be configured as repeaters (both client and base bridges). Configuring AP3 and AP4 as repeaters entails configuring an AP3 and an AP4 radio as both a client bridge and a base bridge. To configure AP3 and AP4 as repeaters, the IT Team does the following:
1. 2. The Trion IT department verifies connectivity with AP3 and AP4 following the instructions in Testing Connectivity on page 3-11. The Trion IT Department installs AP3 and AP4 on light poles (in the middle of the shipping yard) where power is available and a secure mesh network (AP1 and AP2) is already within Configuring Mesh Networking 9-31 broadcast range (see the illustration below). The Trion IT department follows the instructions in Wall Mounted Installations on page 2-14 to install AP3 and AP4. AP1 AP2 AP4 AP3 3. The Trion IT department selects Network Configuration -> LAN from the AP-5131 menu tree. 4. 5. 6. The Trion IT department verifies the LAN used to support the mesh network is enabled for both AP3 and AP4, (by selecting the Enable checkbox). The Trion IT department then selects Network Configuration -> LAN -> trion from the AP-5131 menu tree. The IT team selects the Mesh STP Configuration button on the bottom of the screen. 9-32 AP-51xx Access Point Product Reference Guide 7. The Trion IT department leaves the Priority setting to at 32768 for AP3 and AP4 for both to defer to AP1 (which was assigned a priority of 1 for root designation) as the access point defining the mesh network configuration. The remainder of the Mesh STP Configuration settings are left unchanged from their default values. The team clicks OK from within the Mesh STP Configuration screen and Apply from within the trion (LAN1) screen to save the settings. The Trion IT team now intends to assign WLANs (to use with the trion LAN) that can be dedicated to their mesh network within the shipping yard. The team selects Network Configuration -> Wireless from the AP-5131 menu tree. The Wireless Configuration screen displays with those existing WLANs displayed within the table. Since this is Trions first deployment for AP3 and AP4, the IT department determines the existing default WLAN should be left as is, and a new WLAN should be configured closely resembling the mesh network WLAN defined for AP1 and AP2. 8. Configuring Mesh Networking 9-33 9. The team selects the Edit button to revise (and rename) the existing default WLAN to support mesh networking. 10. The Trion IT team assigns AP3 and AP4 an ESSID of 103. Therefore, AP1 and AP2 should be able to see AP3 and AP4 as soon as they are deployed. 11. The team assigns the name of trion mesh to the WLAN to be consistent with the WLAN supporting mesh networking on AP1 and AP2. 12. The team selects the 802.11a Radio checkbox for both AP3 and AP4. Like AP1, the 802.11b/
g radios will be used to service MUs on a different WLAN, thus segregating MU traffic from the mesh traffic proliferating the 802.11a radio. 9-34 AP-51xx Access Point Product Reference Guide 13. The team does not want any MUs connecting to the mesh WLAN, only the devices comprising the mesh network. Therefore, the team leaves the Maximum MUs field as is, and will use the Radio Configuration page to control the number of client bridge connections. 14. The team verifies the Enable Client Bridge Backhaul checkbox is selected for both AP3 and AP4 to ensure the WLAN is available in the WLAN drop-down menu within the Radio Configuration screen. 15. The IT team then verifies that steps 10 through 14 have been carried out identically for both AP3 and AP4. The IT team now needs to define a security policy for AP3 and AP4 complimentary with the policy created for AP1 and AP2 to both protect the data within the mesh network and ensure all 4 access points within the network can interact with one another. 16. The IT Team selects the Create button to the right of the Security Policy drop-down menu and defines a WPA2/CCMP supported security policy exactly like the one created for AP1 and AP2. For more information, see how the team defined the security policy starting on step 16 within Trions Initial Deployment on page 9-19. It is assumed all of the existing MU traffic defined for AP1 and AP2 will also be used in the extended coverage area for AP3 and AP4 with no known additions to the MU traffic at this time. Thus the IT team refers to the ACL created for AP1 and AP2 and defines an ACL exactly like it for AP3 and AP4. 17. The team selects the Create button (to the right of the MU Access Control drop-down menu and defines an ACL policy like the one created for AP1 and AP2. The team also remembers to go to the AP1 ACL and add AP3 and AP4 to the list of devices allowed to connect to AP1. For more information, see how the team defined the ACL policy starting on step 22 within Trions Initial Deployment on page 9-19. 18. The team decides to leave the Disallow MU to MU Communication checkbox unselected for the mesh WLAN for AP3 and AP4, as the team still considers all MU traffic within the shipping yard known and not a threat to the growing mesh network. 19. The team selects the Use Secure Beacon checkbox from the Edit WLAN screen to not transmit the AP- 5131s ESSID between APs 1 through 4. If a hacker tries to find an ESSID via an MU, the AP- 5131s ESSID does not display since the ESSID is not in the beacon. 20. The team does not select the Accept Broadcast ESSID checkbox, as they still do not want MUs randomly joining their carefully constructed mesh network. Configuring Mesh Networking 9-35 21. Now a QoS policy needs to be defined for the shipping and receiving mesh WLAN. The IT Team still envisions little (if any) video or voice traffic within the shipping as the MUs within primarily scan bar codes and upload data. This holds true for the QoS requirements for AP3 and AP4 as the required coverage area has grown, not the security, access permission or QoS considerations. For more information, see how the team defined the AP1 and AP2 QoS policy starting on step 25 within Trions Initial Deployment on page 9-19. The WLAN configuration has now been set for both AP3 and AP4. The team now needs to define the radio configurations for AP3 and AP4. 22. The IT team selects Network Configuration -> Wireless -> Radio Configuration from the AP-5131 menu tree. The Radio Configuration screen displays. 23. For both AP3 and AP4, the IT Team enables Radio 1 and defines the radio as a repeater
(enabling each radio as both a base and client bridge). Both AP3 and AP4 are intended to pass along mesh network back data to AP1 and support the 802. 11b/g MUs within the shipping yard. 24. The IT Team leaves each radios Max # Client Bridge setting at the default setting of 12. This ensures as client bridges are added to the growing mesh network that they can be accounted for. 25. For both AP3 and AP4, the IT Team uses the Mesh Network Name drop-down menu to assign the trion mesh WLAN to radio 1. This is the WLAN the AP3 and AP4 radios will use to interoperate with the MUs populating the shipping yard. 9-36 AP-51xx Access Point Product Reference Guide 26. As with AP1 and AP2, the IT Team decides to not select the Advanced button within the AP3 and AP4 WLAP Client Bridge Settings field. 27. The Trion IT Team clicks Apply within both the AP3 and AP4 Radio Configuration screens to complete the mesh network configuration of each AP3 and AP4 radio. For the next 9 months, the Trion Enterprises mesh network consists of AP1 and AP2 and now AP3 and AP4 extending the mesh coverage range further into the shipping yard. AP1 is still the root bridge in the mesh network. The IT Team will appraise their mesh requirements in another 9 months and (if necessary) add additional access points and MUs to the mesh network. Configuring Mesh Networking 9-37 9.3.3 Adding 2 More Client Bridges to the Trion Network After an additional six months with their existing 4 access point mesh network, Trion Enterprises needs and approves the addition of two additional access points (AP5 and AP6) to be configured as client bridges. The team will configure AP5 and AP6 as client bridges and not base bridges or repeaters since Trion Enterprises does not plan to expand its shipping yard and the mesh network would have all the access points needed to support it. Thus, one AP5 and AP6 radio will be providing mesh coverage to the outer portion of the shipping yard without having to provide base bridge or repeater support to new members of the mesh network. The remaining AP5 and AP5 radio can support shipping yard MU traffic using a non-mesh WLAN. To configure AP5 and AP6 as client bridges, the IT Team does the following:
1. 2. The Trion IT department verifies connectivity with AP5 and AP6 following the instructions in Testing Connectivity on page 3-11. The Trion IT Department installs AP5 and AP6 on light poles (in a new expanded are of the shipping yard) where power has been made available and a secure mesh network (APs 1-4) is within broadcast range (see the illustration below). The Trion IT department follows the instructions in Wall Mounted Installations on page 2-14 to install AP5 and AP6. AP4 AP6 AP1 AP2 AP3 AP5 s 9-38 AP-51xx Access Point Product Reference Guide 3. The Trion IT department selects Network Configuration -> LAN from the AP-5131 menu tree. 4. 5. 6. The Trion IT department verifies the LAN used to support the mesh network is enabled for both AP5 and AP6, (by selecting the Enable checkbox). The Trion IT department then selects Network Configuration -> LAN -> trion from the AP-5131 menu tree. The IT team selects the Mesh STP Configuration button on the bottom of the screen. Configuring Mesh Networking 9-39 7. The Trion IT department leaves the Priority setting to at 32768 for AP5 and AP6 for both to defer to AP1 (which was assigned a priority of 1 for root designation) as the access point defining the mesh network configuration. The remainder of the Mesh STP Configuration settings are left unchanged from their default values. The team clicks OK from within the Mesh STP Configuration screen and Apply from within the trion (LAN1) screen to save the settings. The Trion IT team now intends to assign WLANs (to use with the trion LAN) that can be dedicated to their mesh network within the shipping yard. The team selects Network Configuration -> Wireless from the AP-5131 menu tree. The Wireless Configuration screen displays with those existing WLANs displayed within the table. Since this is Trions first deployment for AP5 and AP6, the IT department determines the existing default WLAN should be left as is, and a new WLAN should be configured resembling the mesh network WLAN defined for APs 1-4. 8. 9-40 AP-51xx Access Point Product Reference Guide 9. The team selects the Edit button to revise (and rename) the existing default WLAN to support mesh networking. 10. The Trion IT team assigns the WLAN an ESSID of 103 to be consistent with the trion mesh WLAN ESSID of the other four access points within the mesh network. 11. The team assigns the name of trion mesh to the WLAN to be consistent with the WLAN supporting mesh on APs 1-4. 12. The team selects the 802.11a Radio checkbox for both AP5 and AP6. The 802.11b/g radio on both AP5 and AP6 will be used to service MUs (on a different WLAN). Thus, MU traffic will be segregated from the mesh traffic proliferating each APs 802.11a radio. Configuring Mesh Networking 9-41 13. The team still does not want any MUs connecting to the mesh WLAN, only the devices comprising the mesh network. Therefore, the team leaves the Maximum MUs field as is, and will use the Radio Configuration page to control the number of client bridge connections within the mesh WLAN. 14. The team verifies the Enable Client Bridge Backhaul checkbox is selected for both AP5 and AP6 to ensure the WLAN is available in the WLAN drop-down menu within the Radio Configuration screen. 15. The IT team then verifies that steps 10 through 14 have been carried out identically for both AP5 and AP6. The IT team now needs to define a security policy for AP5 and AP4 complimentary with the policy created for APs 1-4. 16. The IT Team defines a WPA2/CCMP security policy exactly like the one created for APs 1-4. For more information, see how the team initially defined the security policy starting on step 16 within Trions Initial Deployment on page 9-19. 17. Existing MU traffic within the mesh network will be used within the expanded shipping yard. Thus, the IT team refers to the ACLs created for APs 1-4 and defines an ACL exactly like it for AP5 and AP6. The team also remembers to go to the ACL for AP1, AP3 and AP4 and add AP5 and AP6 in order for each device in the mesh network to communicate with one another. For more information, refer to step 22 within Trions Initial Deployment on page 9-19. 18. The team decides to leave the Disallow MU to MU Communication checkbox unselected for AP5 and AP6, as the team still considers all MU traffic within the shipping yard known and not a threat to the growing mesh network. 19. The team selects the Use Secure Beacon checkbox from the Edit WLAN screen to not transmit the AP- 5131s ESSID between APs 1 through 6. If a hacker tries to find an ESSID via an MU, the AP- 5131s ESSID does not display since the ESSID is not in the beacon. 20. The team does not select the Accept Broadcast ESSID checkbox, as they still do not want MUs randomly joining their carefully constructed mesh network. 21. The IT Team still envisions little (if any) video or voice traffic within the shipping as the MUs within primarily scan bar codes and upload data. This still holds true for the QoS requirements for AP5 and AP6, as the required coverage area has continued to grow, but not the security, access permissions or QoS considerations. For more information, see how the team defined the QoS policy for APs 1-4 starting on step 25 within Trions Initial Deployment on page 9-19. The team now needs to define the radio configurations for AP5 and AP6. 9-42 AP-51xx Access Point Product Reference Guide 22. The IT team selects Network Configuration -> Wireless -> Radio Configuration from the AP-5131 menu tree. The Radio Configuration screen displays. 23. For both AP5 and AP6, the IT Team enables Radio 1 and defines the radio as a client bridge. 24. For both AP5 and AP6, the IT Team uses the Mesh Network Name drop-down menu to assign the trion mesh WLAN to radio 1. 25. As with APs 1-4, the IT Team decides to not select the Advanced button within the WLAP Client Bridge Settings field. 26. The Trion IT Team clicks Apply within both the AP5 and AP6 Radio Configuration screens to complete the mesh network configuration of each AP5 and AP6 radio. For the foreseeable future, the Trion Enterprises mesh network will consist of APs 1-6. AP1 remains the root bridge in the mesh network. If the physical radio coverage area requirements of the mesh network were to grow, AP5 and AP6 would have to be changed from client bridges to repeaters to associate with the new APs required to extent the coverage area. But for now, the 802.11a radio of both AP5 and AP6 can remain defined as a client bridge to support the outer fringes of the Trion Enterprises shipping yard.

Obtains and applies the expected IP Address from the DHCP Server
Downloads the firmware and configuration files from the TFTP Server and updates both as required. Usage Scenarios B-5
Verify the file versions within the access points System Settings screen. B.1.1.3 DHCP Priorities The following flowchart indicates the priorities used by the access point when the DHCP server is configured for options.
--------------------------------------------------------------------------------------------
If the DHCP Server is configured for options 186 and 66 (to assign TFTP Server IP addresses) the access point uses the IP address configured for option 186. Similarly, if the DHCP Server is configured for options 187 and 67 (for the firmware file) the access point uses the file name configured for option 187. If the DHCP Server is configured for embedded and global options, the embedded options take precedence. B-6 AP-51xx Access Point Product Reference Guide B.1.2 Linux - BootP Server Configuration See the following sections for information on these BootP server configurations in the Linux environment:
BootP Options
BootP Priorities B.1.2.1 BootP Options This section contains instructions for the automatic update of the access point firmware and configuration file using a BootP Server. The setup example described in this section includes:
1 AP-5131 or AP-5181 model access point
1 Linux/Unix BOOTP Server
1 TFTP Server. Please note the following caveats regarding this procedure before beginning:
The LAN Port needs to be configured as a BootP client.
No BootP support is available on the WAN Port.
If the existing and update firmware files are the same, the firmware will not get updated. To configure BootP options using a Linux/Unix BootP Server:
1. Set the Linux/Unix BootP Server and access point on the same Ethernet segment. 2. Configure the bootptab file (/etc/bootptab) on the Linux/Unix BootP Server in any one of the formats that follows:
Using options 186, 187 and 188:
A P-5131:ha =00a0f88aa6d8\ < LA N M A C A ddress>
:sm =255.255.255.0\ <S ubnet M ask>
:ip=157.235.93.128\ <IP A ddress>
:gw =157.235.9 3.2\ <gatew ay>
:T 186=157.235.93.250\ <TFTP S erver IP>
:T 187="apfw .bin"\ <Firm w are file>
:T 188="cfg.txt": <C onfigu ration file>
Usage Scenarios B-7 Using options 66, 67 and 129:
A P-5131:ha=00a 0f88aa6d8\ < LA N M A C A ddress>
:sm =255.2 55.255.0\ <S ubnet M ask>
:ip=157.23 5.93.128\ <IP A ddress>
:gw =157.2 35.93.2\ <gatew ay>
:T66=157 .235.93.250\ < TFTP S erver IP>
:T67="apfw .bin"\ <Firm w are file>
:T129="cfg.txt": <C onfiguration file>
Using options sa, bf and 136:
AP-5131:ha=00a0f88aa6d8\ < LAN M AC Address>
:sm=255.255.255.0\ <Subnet M ask>
:ip=157.235.93.128\ <IP Address>
:gw=157.235.93.2\ <gateway>
:sa=157.235.93.250\ <TFTP Server IP>
:bf=/tftpboot/cfg.txt\ <Configuration file>
:T136=/tftpboot/: <TFTP root directory>
NOTE bf option prefixes a forward slash (/) to the firmware file name. This may not be supported on Windows based TFTP Servers. 3. Copy the firmware and configuration files to the appropriate directory on the TFTP Server. This has to be changed to the LAN Port. Additionally, the LAN Interface needs to be configured as a BootP Client. 4. Restart the access point. 5. While the access point boots, verify the access point:
Obtains and applies the expected IP Address from the BootP Server.
Downloads both the firmware and configuration files from the TFTP Server and updates them as required. Verify the file versions within the access point System Settings screen. B-8 AP-51xx Access Point Product Reference Guide B.1.2.2 BootP Priorities The following flowchart displays the priorities used by the access point when the BootP server is configured for multiple options:
If the BootP Server is configured for options 186 and 66 (to assign TFTP server IP addresses) the access point uses the IP address configured for option 186. Similarly, if the BootP Server is configured for options 188 and 129 (for the configuration file) the access point uses the file name configured for option 188. B.2 Configuring an IPSEC Tunnel and VPN FAQs The access point has the capability to create a tunnel between an access point and a VPN endpoint. The access point can also create a tunnel from one access point to another access point. The following instruction assumes the reader is familiar with basic IPSEC and VPN terminology and technology.
Configuring a VPN Tunnel Between Two Access Points
Configuring a Cisco VPN Device
Frequently Asked VPN Questions B.2.1 Configuring a VPN Tunnel Between Two Access Points The access point can connect to a non-AP device supporting IPSec, such as a Cisco VPN device -
labeled as "Device #2". Usage Scenarios B-9 For this usage scenario, the following components are required:
2 AP-5131 or AP-5181 model access points
1 PC on each side of the access points LAN. To configure a VPN tunnel between two access points:
Ensure the WAN ports are connected via the internet. 1. 2. On access point #1, select WAN -> VPN from the main menu tree. 3. Click Add to add the tunnel to the list. 4. Enter a tunnel name (tunnel names do not need to match). Enter the WAN port IP address of AP #1 for the Local WAN IP. 5. 6. Within the Remote Subnet and Remote Subnet Mask fields, enter the LAN IP subnet and mask of AP #2 /Device #2. Enter the WAN port IP address of AP #2/ Device #2 for a Remote Gateway. 7. 8. Click Apply to save the changes. B-10 AP-51xx Access Point Product Reference Guide NOTE For this example, Auto IKE Key Exchange is used. Any key exchange can be used, depending on the security needed, as long as both devices on each end of the tunnel are configured exactly the same. 9. Select the Auto (IKE) Key Exchange checkbox. 10. Select the Auto Key Settings button. 11. For the ESP Type, select ESP with Authentication and use AES 128-bit as the ESP Encryption Algorithm. Click OK. 12. Select the IKE Settings button. Usage Scenarios B-11 13. Select Pre Shared Key (PSK) from the IKE Authentication Mode drop-down menu. 14. Enter a Passphrase. Passphrases must match on both VPN devices. NOTE Ensure the IKE authentication Passphrase is the same as the Pre-shared key on the Cisco PIX device. 15. Select AES 128-bit as the IKE Encryption Algorithm. 16. Select Group 2 as the Diffie -Hellman Group. Click OK. This will take you back to the VPN screen. 17. Click Apply to make the changes 18. Check the VPN Status screen. Notice the status displays "NOT_ACTIVE". This screen automatically refreshes to get the current status of the VPN tunnel. Once the tunnel is active, the IKE_STATE changes from NOT_CONNECTED to SA_MATURE. B-12 AP-51xx Access Point Product Reference Guide 19. On access point #2/ Device #2, repeat the same procedure. However, replace access point
#2 information with access point #1 information. 20. Once both tunnels are established, ping each side of the tunnel to ensure connectivity. B.2.2 Configuring a Cisco VPN Device This section includes general instructions for configuring a Cisco PIX Firewall 506 series device. For the usage scenario described in this section, you will require the following:
1 Cisco VPN device
1 PC connected to the LAN side of the access pointand the Cisco PIX. NOTE The Cisco PIX device configuration should match the access point VPN configuration in terms of Local WAN IP (PIX WAN), Remote WAN Gateway (access point WAN IP), Remote Subnet (access point LAN Subnet), and the Remote Subnet Mask. The Auto Key Settings and the IKE Settings on the Cisco PIX should match the access point Key and IKE settings. Below is how the access point VPN Status screen should look if the entire configuration is setup correctly once the VPN tunnel is active. The status field should display "ACTIVE". Usage Scenarios B-13 B.2.3 Frequently Asked VPN Questions The following are common questions that arise when configuring a VPN tunnel using the access point. Question 1: Does the access point IPSec tunnel support multiple subnets on the other end of a VPN concentrator?
Yes. The access point can access multiple subnets on the other end of the VPN Concentrator from the access point's Local LAN Subnet by:
Creating multiple VPN Tunnels. The AP supports a maximum of 25 tunnels.
When using the Remote Subnet IP Address with an appropriate subnet mask, the AP can access multiple subnets on the remote end. For example: If creating a tunnel using 192.168.0.0/16 for the Remote Subnet IP address, the following subnets could be accessed:
192.168.1.x 192.168.2.x 192.168.3.x, etc B-14 AP-51xx Access Point Product Reference Guide
Question 2: Even if a wildcard entry of "0.0.0.0" is entered in the Remote Subnet field in the VPN configuration page, can the AP access multiple subnets on the other end of a VPN concentrator for the APs LAN/WAN side?
No. Using a "0.0.0.0" wildcard is an unsupported configuration. In order to access multiple subnets, the steps in Question #1 must be followed.
Question 3: Can the AP be accessed via its LAN interface of AP#1 from the local subnet of AP#2 and vice versa?
Yes.
Question 4: Will the default "Manual Key Exchange" settings work without making any changes?
No. Changes need to be made. Enter Inbound and Outbound ESP Encryption keys on both APs. Each one should be of 16 Hex characters (depending on the encryption or authentication scheme used). The VPN tunnel can be established only when these corresponding keys match. Ensure the Inbound/Outbound SPI and ESP Authentication Keys have been properly specified.
Question 5: Can a tunnel between an access point and a WS2000 be established?
Yes. Usage Scenarios B-15
Question 6: Can an IPSec tunnel over a PPPoE connection be established - such as a PPPoE enabled DSL link?
Yes. The access point supports tunneling when using a PPPoE username and password.
Question 7: Can I setup an access point so clients can access both the WAN normally and only use the VPN when talking to specific networks?
Yes. Only packets that match the VPN Tunnel Settings will be sent through the VPN tunnel. All other packets will be handled by whatever firewall rules are set.
Question 8: How do I specify which certificates to use for an IKE policy from the access point certificate manager?
When generating a certificate to use with IKE, use one of the following fields: IP address, Domain Name, or Email address. Also, make sure you are using NTP when attempting to use the certificate manager. Certificates are time sensitive. Configure the following on the IKE Settings page:
Local ID type refers to the way that IKE selects a local certificate to use.
IP - tries the match the local WAN IP to the IP addresses specified in a local certificate.
FQDN - tries to match the user entered local ID data string to the domain name field of the certificate.
UFQDN - tries to match the user entered local ID data string to the email address field of the certificate. Remote ID type refers to the way you identify an incoming certificate as being associated with the remote side.
IP - tries the match the remote gateway IP to the IP addresses specified in the received certificate.
FQDN - tries to match the user entered remote ID data string to the domain name field of the received certificate. B-16 AP-51xx Access Point Product Reference Guide
UFQDN - tries to match the user entered remote ID data string to the email address field of the received certificate.
Question 9: I am using a direct cable connection between my two VPN gateways for testing and cannot get a tunnel established, yet it works when I set them up across another network or router. Why?
The packet processing architecture of the access point VPN solution requires the WAN default gateway to work properly. When connecting two gateways directly, you don't need a default gateway when the two addresses are on the same subnet. As a workaround, point the access point's WAN default gateway to be the other VPN gateway and vice-versa.
Question 10: I have setup my tunnel and the status still says 'Not Connected'. What should I do now?
VPN tunnels are negotiated on an "as-needed" basis. If you have not sent any traffic between the two subnets, the tunnel will not get established. Once a packet is sent between the two subnets, the VPN tunnel setup occurs. Usage Scenarios B-17
Question 11: I still can't get my tunnel to work after attempting to initiate traffic between the two subnets. What now?
Try the following troubleshooting tips:
Verify you can ping each of the remote Gateway IP addresses from clients on either side. Failed pings can indicate general network connection problems.
Pinging the internal gateway address of the remote subnet should run the ping through the tunnel as well. Allowing you to test, even if there are no clients on the remote end.
Question 12: My tunnel works fine when I use the LAN-WAN Access page to configure my firewall. Now that I use Advanced LAN Access, my VPN stops working. What am I doing wrong?
VPN requires certain packets to be passed through the firewall. Subnet Access automatically inserts these rules for you when you do VPN. Advanced Subnet Access requires these rules to be in effect for each tunnel.
An 'allow' inbound rule. Scr Dst Transport Scr port Dst port Rev NAT
<Remote Subnet IP range>
<Local Subnet IP range>
ANY 1:65535 1:65535 None
An 'allow' outbound rule. Scr Dst Transport Scr port Dst port NAT
<Local Subnet IP range>
<Remote Subnet IP range>
ANY 1:65535 1:65535 None
For IKE, an 'allow' inbound rule. B-18 AP-51xx Access Point Product Reference Guide Scr Dst Transport Scr port Dst port Rev NAT
<Remote Subnet IP range>
<WAN IP address>
UDP 1:65535 500 None These three rules should be configured above all other rules (default or user defined). When Advanced LAN Access is used, certain inbound/outbound rules need to be configured to control incoming/outgoing packet flow for IPSec to work properly (with Advanced LAN Access). These rules should be configured first before other rules are configured.
Question 13: Do I need to add any special routes on the access point to get my VPN tunnel to work?
No. However, clients could need extra routing information. Clients on the local LAN side should either use the access point as their gateway or have a route entry tell them to use the access point as the gateway to reach the remote subnet. B.3 Replacing an AP-4131 with an AP-5131 or AP-5181 The access points modified default configuration enables an access point to not only operate in a single-cell environrment, but also function as a replacement for legacy Symbol AP-4131 model access points. You cannot port an access points configuration file to an access point, but you can configure an access point similarly and provide an improved data rate and feature set. An AP-4131 has only one LAN port and it is defaulted to DHCP/BOOTP enabled. The access point is optimized for single-cell deployment, so it should allow the customer to use an access point as a drop-in replacement for an existing AP-4131 deployment. However, to optimally serve as a replacement for existing AP-4131 deployments, the access points out-of-box defaults are now set as follows:
The access points LAN1 port must default to DHCP client mode
The access points LAN2 port must default to DHCP server mode
The access points WAN port must default to Static mode.
The default gateway now defaults to LAN1. Usage Scenarios B-19
The interface parameter has been removed from the Auto Update configuration feature.
The WAN interface now has http/telnet/https/ssh connectivity enabled by default.
