(SMC2552W-G) is an IEEE 802.11b/g access point that provides transparent, wireless high-speed data communications between the wired LAN and fixed, portable or mobile devices equipped with a 802.11b, or 802.11g wireless adapter. This solution offers fast, reliable wireless connectivity with considerable cost savings over wired LANs (which include long-term maintenance overhead for cabling). Using 802.11b and 802.11g technology, this access point can easily replace a 10 Mbps Ethernet connection or seamlessly integrate into a 10/100 Mbps Ethernet LAN. In addition, the access point offers full network management capabilities through an easy to configure web interface, a command line interface for initial configuration and troubleshooting, and support for Simple Network Management tools, such as SMCs EliteView. Radio Characteristics The IEEE 802.11b/g standard uses a radio modulation technique known as Orthogonal Frequency Division Multiplexing (OFDM), and a shared collision domain

(CSMA/CA). It operates at 2.4 GHz for connections to 802.11g clients. IEEE 802.11g includes backward compatibility with the IEEE 802.11b standard. IEEE 802.11b also operates at 2.4 GHz, but uses Direct Sequence Spread Spectrum (DSSS) modulation technology to achieve a communication rate of up to 11 Mbps. 1-1 Introduction The access point also supports a 54 Mbps half-duplex connection to Ethernet networks for each active channel.

Please register this product and upgrade the product warranty at www.smc.com 1-2 Hardware Description Hardware Description Front Panel Antennas Rear Panel Security Slot Console Port RJ-45 Port, PoE Connector Reset Button 3.3V/4A Power Socket LED Indicator 1-3 Introduction Component Description Antennas The access point includes two antennas for wireless communications. The signal transmitted from both antennas is identical, but only the best signal received on one of the antennas is used. The antennas transmit the outgoing signal as a toroidal sphere, so the antennas should be adjusted to different angles to provide better coverage. For further information, see Positioning the Antennas on page 2-3. LED Indicators The access point includes three status LED indicators, as described in the following figure and table. LAN WLAN Power Ethernet Link/Activity 802.11g Wireless Link/Activity LED LED1 Status Description Green/Amber Off: No power. Green On: Power On and Ready for Operation. Amber: H/W error or system error. Slow Green Blink: Power On but Not Ready for Operation-at initial power on or reset, this indicates self-test or software loading. 1-4 Hardware Description LED LED2 Status Description Green/Amber Off: No Ethernet Link Detected or admin disable. Green On: 100Mbps Ethernet Link Detected but No Activity. Amber On: 10Mbps Ethernet Link Detected but No Activity. Green Blink: 10/100Mbps Ethernet Link Activity. Green LED3

(WLAN 11g) Off: Wireless Link admin Disabled. Green On: Associated with Network but No Activity. Green Blink: Activity. Security Slot The access point includes a Kensington security slot on the rear panel. You can prevent unauthorized removal of the access point by wrapping the Kensington security cable (not provided) around an unmovable object, inserting the lock into the slot, and turning the key. Console Port This port is used to connect a console device to the access point through a serial cable. This connection is described under Console Port Pin Assignments on page C-4. The console device can be a PC or workstation running a VT-100 terminal emulator, or a VT-100 terminal. Ethernet Port The access point has one 10BASE-T/100BASE-TX RJ-45 port that can be attached directly to 10BASE-T/100BASE-TX LAN segments. These segments must conform to the IEEE 802.3 or 802.3u specifications. 1-5 Introduction This port uses an MDI (i.e., internal straight-through) pin configuration. You can therefore use straight-through twisted-pair cable to connect this port to most network interconnection devices such as a switch or router that provide MDI-X ports. However, when connecting the access point to a workstation or other device that does not have MDI-X ports, you must use crossover twisted-pair cable. The access point appears as an Ethernet node and performs a bridging function by moving packets from the wired LAN to remote workstations on the wireless infrastructure. Note: The RJ-45 port also supports Power over Ethernet (PoE) based on the IEEE 802.3af standard. Refer to the description for the Power Connector for information on supplying power to the access points network port from a network device, such as a switch, that provides Power over Ethernet (PoE). Reset Button This button is used to reset the access point or restore the factory default configuration. If you hold down the button for less than 5 seconds, the access point will perform a hardware reset. If you hold down the button for 5 seconds or more, any configuration changes you may have made are removed, and the factory default configuration is restored to the access point. Power Connector The access point does not have a power switch. It is powered on when connected to the AC power adapter, and the power adapter is connected to a power source. The access point automatically adjusts to any voltage between 100-240 volts at 50 or 60 Hz. No voltage range settings are required. The access point may also receive Power over Ethernet (PoE) from a switch or other network device that supplies power over the network cable based on the IEEE 802.3af standard. 1-6 Features and Benefits Note that if the access point is connected to a PoE source device and also connected to a local power source through the AC power adapter, PoE will be disabled.

Frequently changing environments Retailers, manufacturers, and banks that frequently rearrange the workplace or change location.

Temporary LANs for special projects or peak times Trade shows, exhibitions and construction sites which need temporary setup for a short time period. Retailers, airline and shipping companies that need additional workstations for a peak period. Auditors who require workgroups at customer sites.

Access to databases for mobile workers Doctors, nurses, retailers, or white-collar workers who need access to databases while being mobile in a hospital, retail store, or an office campus. 1-8 Chapter 2 Network Configuration The wireless solution supports a stand-alone wireless network configuration as well as an integrated configuration with 10/100 Mbps Ethernet LANs. Wireless network cards, adapters, and access points can be configured as:

Ad hoc for departmental, or enterprise LANs

Infrastructure for wireless LANs

Infrastructure wireless LAN for roaming wireless PCs The 802.11b and 802.11g frequency band which operates at 2.4 GHz can easily encounter interference from other 2.4 GHz devices, such as other 802.11b or g wireless devices, cordless phones and microwave ovens. If you experience poor wireless LAN performance, try the following measures:

Limit any possible sources of radio interference within the service area

Increase the distance between neighboring access points

Decrease the signal strength of neighboring access points

Increase the channel separation of neighboring access points

(e.g., up to 3 channels of separation for 802.11b or up to 5 channels for 802.11g) 2-1 Network Configuration Network Topologies Ad Hoc Wireless LAN (no AP or Bridge) An ad hoc wireless LAN consists of a group of computers, each equipped with a wireless adapter, connected via radio signals as an independent wireless LAN. Computers in a specific ad hoc wireless LAN must therefore be configured to the same radio channel. Ad Hoc Wireless LAN Notebook with Wireless USB Adapter Notebook with Wireless PC Card PC with Wireless PCI Adapter 2-2 Network Topologies Infrastructure Wireless LAN The access point also provides access to a wired LAN for wireless workstations. An integrated wired/wireless LAN is called an Infrastructure configuration. A Basic Service Set (BSS) consists of a group of wireless PC users, and an access point that is directly connected to the wired LAN. Each wireless PC in this BSS can talk to any computer in its wireless group via a radio link, or access other computers or network resources in the wired LAN infrastructure via the access point. The infrastructure configuration not only extends the accessibility of wireless PCs to the wired LAN, but also increases the effective wireless transmission range for wireless PCs by passing their signal through one or more access points. A wireless infrastructure can be used for access to a central database, or for connection between mobile workers, as shown in the following figure. Wired LAN Extension to Wireless Adapters File Server Desktop PC Switch Notebook with Wireless PC Card Adapter Access Point PC with Wireless PCI Adapter 2-3 Network Configuration Infrastructure Wireless LAN for Roaming Wireless PCs The Basic Service Set (BSS) defines the communications domain for each access point and its associated wireless clients. The BSS ID is a 48-bit binary number based on the access points wireless MAC address, and is set automatically and transparently as clients associate with the access point. The BSS ID is used in frames sent between the access point and its clients to identify traffic in the service area. The BSS ID is only set by the access point, never by its clients. The clients only need to set the Service Set Identifier (SSID) that identifies the service set provided by one or more access points. The SSID can be manually configured by the clients, can be detected in an access points beacon, or can be obtained by querying for the identity of the nearest access point. For clients that do not need to roam, set the SSID for the wireless card to that used by the access point to which you want to connect. 2-4 Network Topologies A wireless infrastructure can also support roaming for mobile workers. More than one access point can be configured to create an Extended Service Set (ESS). By placing the access points so that a continuous coverage area is created, wireless users within this ESS can roam freely. All SMC wireless network cards and adapters and SMC2552W-G wireless access points within a specific ESS must be configured with the same SSID.

Seamless Roaming 2-5 Network Configuration 2-6 Chapter 3 Hardware Installation 1. Select a Site Choose a proper place for the access point. In general, the best location is at the center of your wireless coverage area, within line of sight of all wireless devices. Try to place the access point in a position that can best cover its Basic Service Set (refer to Infrastructure Wireless LAN on page 2-3). Normally, the higher you place the access point, the better the performance. 2. Mount the Access Point The access point can be mounted on any horizontal surface or wall. You can mount the access point on a wall as shown in the illustrations on the next page. Mounting on a horizontal surface To keep the access point from sliding on the surface, attach the four rubber feet provided in the accessory kit to the embossed circles on the bottom of the access point. Mounting on a wall The access point should be mounted only to a wall or wood surface that is at least 1/2-inch plywood or its equivalent. Position the mounting bracket on the wall, and mark the holes. The orientation shown in the following figure is the most secure position for mounting the access point. Do not mount the access point with the retaining latches pointing down. To mount the access point on a plastered brick or concrete wall, first drill four holes 22 mm deep and 3.5 mm in diameter, and press the four included wall plugs firmly into the drilled holes until they are flush with the surface of the wall. 3-1 Hardware Installation Set the four 5/8-inch number 12 wood screws in the holes, leaving about 3 mm clearence from the wall. Position the mounting bracket over the wall screws, slide the bracket onto the screws, and then tighten down the screws. 3. Attaching the Bracket Line up the three mounting points on the bracket with the three mounting slots on the rear of the access point, as directed in the figure on the next page. Place the mounting points of the bracket into the mounting slots of the access point and while pushing down on the bracket, slide it into position so that the two retaining latches slip into place over the back of the access point. 3-2 Hardware Installation Attaching the Mounting Bracket 4. Lock the Access Point in Place To prevent unauthorized removal of the access point, you can use a Kensington Slim MicroSaver security cable (not included) to attach the access point to a fixed object. 3-3 Hardware Installation 5. Connect the Power Cord Connect the power adapter to the access point, and the power cord to an AC power outlet. Otherwise, the access point can derive its operating power directly from the RJ-45 port when connected to a device that provides IEEE 802.3af compliant Power over Ethernet (PoE). Note: If the access point is connected to both a PoE source device and an AC power source, PoE will be disabled. Warning: Use ONLY the power adapter supplied with this access point. Otherwise, the product may be damaged. 6. Observe the Self Test When you power on the access point, verify that the PWR indicator stops flashing and remains on, and that the other indicators start functioning as described under LED Indicators on page 1-4. If the PWR LED does not stop flashing, the self test has not completed correctly. Refer to Troubleshooting on page A-1. 7. Connect the Ethernet Cable The access point can be wired to a 10/100 Mbps Ethernet through a network device such as a hub or a switch. Connect your network to the RJ-45 port on the back panel with category 3, 4, or 5 UTP Ethernet cable. When the access point and the connected device are powered on, the Ethernet Link LED should light indicating a valid network connection. Note: The RJ-45 port on the access point uses an MDI pin configuration, so you must use straight-through cable for network connections to hubs or switches that only have MDI-X ports, and crossover cable for network connections to PCs, servers or other end nodes that only have MDI ports. However, if the device to which you are connecting supports auto-MDI/MDI-X operation, you can use either straight-through or crossover cable. 8. Position the Antennas The antennas emit signals along a toroidal plane, and thus provide more effective coverage when positioned along different axes. For example, you might 3-4 Hardware Installation position the antennas around 45 to 90 degrees from each other. The access point also compares the strength of an incoming signal on both antennas, and uses the antenna receiving the stronger signal to communicate with a wireless client. 9. Connect the Console Port Connect the console cable

(included) to the RS-232 console port for accessing the command-line interface. You can manage the access point using the console port (Chapter 6), the web interface

(Chapter 5), or SNMP management software such as SMCs EliteView. 3-5 Hardware Installation 3-6 Chapter 4 Initial Configuration The EliteConnect 2.4GHz 802.11g Wireless Access Point SMC2552W-G offers a variety of management options, including a web-based interface, a direct connection to the console port, or using SNMP software such as SMCs EliteView. The initial configuration steps can be made through the web browser interface using the Setup Wizard (page 4-4). The default address is DHCP client. If this address is not compatible with your network, you can first use the command line interface (CLI) as described below to configure a valid address. Note: Units sold in countries outside the United States are not configured with a specific country code. You must use the CLI to set the country code and enable wireless operation

(page 4-4). Initial Setup through the CLI Required Connections The SMC2552W-G provides an RS-232 serial port that enables a connection to a PC or terminal for monitoring and configuration. Attach a VT100-compatible terminal, or a PC running a terminal emulation program to the access point. You can use the console cable provided with this package, or use a null-modem cable that complies with the wiring assignments shown on page C-4. 4-1 Initial Configuration To connect to the console port, complete the following steps:

1. Connect the console cable to the serial port on a terminal, or a PC running terminal emulation software, and tighten the captive retaining screws on the DB-9 connector. 2. Connect the other end of the cable to the RS-232 serial port on the access point. 3. Make sure the terminal emulation software is set as follows:

Select the appropriate serial port (COM port 1 or 2).

Set the data rate to 9600 baud.

Set the data format to 8 data bits, 1 stop bit, and no parity.

Set flow control to none.

Set the emulation mode to VT100.

When using HyperTerminal, select Terminal keys, not Windows keys. Note: When using HyperTerminal with Microsoft Windows 2000, make sure that you have Windows 2000 Service Pack 2 or later installed. Windows 2000 Service Pack 2 fixes the problem of arrow keys not functioning in HyperTerminals VT100 emulation. See www.microsoft.com for information on Windows 2000 service packs. 4. Once you have set up the terminal correctly, press the [Enter]

key to initiate the console connection. The console login screen will be displayed. For a description of how to use the CLI, see Using the Command Line Interface on page 6-1. For a list of all the CLI commands and detailed information on using the CLI, refer to Command Groups on page 6-10. 4-2 Initial Setup through the CLI Initial Configuration Steps Logging In Enter admin for the user name. The default password is null, so just press [Enter] at the password prompt. The CLI prompt appears displaying the access points model number. Username: admin Password: smcadmin SMC Enterprise AP#

Setting the IP Address By default, the access point is configured to obtain IP address settings from a DHCP server. You will therefore have to use the command line interface (CLI) to assign an IP address that is compatible with your network. Type configure to enter configuration mode, then type interface ethernet to access the Ethernet interface-configuration mode. SMC Enterprise AP#configure SMC Enterprise AP(config)#interface ethernet SMC Enterprise AP(config-if)#

First type no dhcp to disable DHCP client mode. Then type ip address ip-address netmask gateway, where ip-address is the access points IP address, netmask is the network mask for the network, and gateway is the default gateway router. Check with your system administrator to obtain an IP address that is compatible with your network. SMC Enterprise AP(if-ethernet)#no dhcp SMC Enterprise AP(if-ethernet)#ip address 192.168.2.2 255.255.255.0 192.168.2.254 SMC Enterprise AP(if-ethernet)#

After configuring the access points IP parameters, you can access the management interface from anywhere within the attached network. The command line interface can also be 4-3 Initial Configuration accessed using Telnet from any computer attached to the network. Setting the Country Code Units sold in the United States are configured by default to use only radio channels 1-11 as defined by FCC regulations. Units sold in other countries are configured by default without a country code (i.e., 99). You must use the CLI to set the country code. Setting the country code restricts operation of the access point to the radio channels permitted for wireless networks in the specified country. Type exit to leave configuration mode. Then type country? to display the list of countries. Select the code for your country, and enter the country command again, following by your country code

(e.g., CA for Canada). SMC Enterprise AP#country ca SMC Enterprise AP#

5-5 System Configuration TCP / IP Settings Configuring the SMC2552W-G with an IP address expands your ability to manage the access point. A number of access point features depend on IP addressing to operate. Note: You can use the web browser interface to access IP addressing only if the access point already has an IP address that is reachable through your network. By default, the SMC2552W-G will be automatically configured with IP settings from a Dynamic Host Configuration Protocol

(DHCP) server. However, if you are not using a DHCP server to configure IP addressing, use the CLI to manually configure the initial IP values (page 4-3). After you have network access to the access point, you can use the web browser interface to modify the initial IP configuration, if needed. Note: If there is no DHCP server on your network, or DHCP fails, the access point will automatically start up with a default IP address of 192.168.2.2. 5-6 Advanced Configuration DHCP Client (Enable) Select this option to obtain the IP settings for the access point from a DHCP (Dynamic Host Configuration Protocol) server. The IP address, subnet mask, default gateway, and Domain Name Server (DNS) address are dynamically assigned to the access point by the network DHCP server. (Default: Enable) DHCP Client (Enable) Select this option to manually configure a static address for the access point.

IP Address: The IP address of the access point. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods.

Subnet Mask: The mask that identifies the host address bits used for routing to specific subnets.

Default Gateway: The default gateway is the IP address of the router for the access point, which is used if the requested destination address is not on the local subnet. If you have management stations, DNS, RADIUS, or other network servers located on another subnet, type the IP address of the default gateway router in the text field provided. Otherwise, leave the address as all zeros (0.0.0.0).

Primary and Secondary DNS Address: The IP address of Domain Name Servers on the network. A DNS maps numerical IP addresses to domain names and can be used to identify network hosts by familiar names instead of the IP addresses. If you have one or more DNS servers located on the local network, type the IP addresses in the text fields provided. Otherwise, leave the addresses as all zeros (0.0.0.0). 5-7 System Configuration CLI Commands for TCP/IP Settings From the global configuration mode, enter the interface configuration mode with the interface ethernet command. Use the ip dhcp command to enable the DHCP client, or no ip dhcp to disable it. To manually configure an address, specify the new IP address, subnet mask, and default gateway using the ip address command. To specify DNS server addresses use the dns server command. Then use the show interface ethernet command from the Exec mode to display the current IP settings. 6-68 6-71 6-69 6-68 6-68 6-12 6-72 SMC-AP(config)#interface ethernet Enter Ethernet configuration commands, one per line.

5-8 Advanced Configuration Radius Remote Authentication Dial-in User Service (RADIUS) is an authentication protocol that uses software running on a central server to control access to RADIUS-aware devices on the network. An authentication server contains a database of user credentials for each user that requires access to the network. A primary RADIUS server must be specified for the SMC2552W-G to implement IEEE 802.1x network access control and Wi-Fi Protected Access (WPA) wireless security. A secondary RADIUS server may also be specified as a backup should the primary server fail or become inaccessible. Note: This guide assumes that you have already configured RADIUS server(s) to support the access point. Configuration of RADIUS server software is beyond the scope of this guide, refer to the documentation provided with the RADIUS server software. Primary Radius Server Setup Configure the following settings to use RADIUS authentication on the access point. 5-9 System Configuration

IP Address: Specifies the IP address or host name of the RADIUS server.

Port: The UDP port number used by the RADIUS server for authentication messages. (Range: 1024-65535;

Default: 1812)

Key: A shared text string used to encrypt messages between the access point and the RADIUS server. Be sure that the same text string is specified on the RADIUS server. Do not use blank spaces in the string. (Maximum length: 255 characters)

Timeout: Number of seconds the access point waits for a reply from the RADIUS server before resending a request.

(Range: 1-60 seconds; Default: 5)

Retransmit attempts: The number of times the access point tries to resend a request to the RADIUS server before authentication fails. (Range: 1-30; Default: 3) Note: For the Timeout and Retransmit attempts fields, accept the default values unless you experience problems connecting to the RADIUS server over the network. Secondary Radius Server Setup Configure a secondary RADIUS server to provide a backup in case the primary server fails. The access point uses the secondary server if the primary server fails or becomes inaccessible. Once the access point switches over to the secondary server, it periodically attempts to establish communication again with primary server. If communication with the primary server is re-established, the secondary server reverts to a backup role. 5-10 Advanced Configuration CLI Commands for RADIUS From the global configuration mode, use the radius-server address command to specify the address of the primary or secondary RADIUS servers. (The following example configures the settings for the primary RADIUS server.) Configure the other parameters for the RADIUS server. Then use the show show radius command from the Exec mode to display the current settings for the primary and secondary RADIUS servers.

5-11 System Configuration Authentication Wireless clients can be authenticated for network access by checking their MAC address against the local database configured on the access point, or by using the IEEE 802.1x network access authentication protocol to look up their MAC addresses on a RADIUS server. The 802.1x protocol can also be configured to check other user credentials such as a user name and password. MAC Authentication You can configure a list of the MAC addresses for wireless clients that are authorized to access the network. This provides a basic level of authentication for wireless clients attempting to gain access to the network. A database of authorized MAC addresses can be stored locally on the SMC2552W-G or remotely on a central RADIUS server.

(Default: Local MAC)

Local MAC: The MAC address of the associating station is compared against the local database stored on the access point. The Local MAC Authentication section enables the local 5-12 Advanced Configuration database to be set up.

Radius MAC: The MAC address of the associating station is sent to a configured RADIUS server for authentication. When using a RADIUS authentication server for MAC address authentication, the server must first be configured in the Radius window (page 5-9).

Disable: No checks are performed on an associating stations MAC address. Local MAC Authentication Configures the local MAC authentication database. The MAC database provides a mechanism to take certain actions based on a wireless clients MAC address. The MAC list can be configured to allow or deny network access to specific clients.

System Default: Specifies a default action for all unknown MAC addresses (that is, those not listed in the local MAC database).

Deny: Blocks access for all MAC addresses except those listed in the local database as allowed. Allow: Permits access for all MAC addresses except those listed in the local database as denied.

MAC Authentication Settings: Enters specified MAC addresses and permissions into the local MAC database.

- MAC Address: Physical address of a client. Enter six pairs of hexadecimal digits separated by hyphens; for example, 00-90-D1-12-AB-89. Permission: Select Allow to permit access or Deny to block access. If Delete is selected, the specified MAC address entry is removed from the database. Update: Enters the specified MAC address and permission setting into the local database.

5-13 System Configuration

MAC Authentication Table: Displays current entries in the local MAC database. 802.1x Setup IEEE 802.1x is a standard framework for network access control that uses a central RADIUS server for user authentication. This control feature prevents unauthorized access to the network by requiring an 802.1x client application to submit user credentials for authentication. The 802.1x standard uses the Extensible Authentication Protocol (EAP) to pass user credentials

(either digital certificates, user names and passwords, or other) from the client to the RADIUS server. Client authentication is then verified on the RADIUS server before the access point grants client access to the network. The 802.1x EAP packets are also used to pass dynamic unicast session keys and static broadcast keys to wireless clients. Session keys are unique to each client and are used to encrypt and correlate traffic passing between a specific client and the access point. You can also enable broadcast key rotation, so the access point provides a dynamic broadcast key and changes it at a specified interval. You can enable 802.1x as optionally supported or as required to enhance the security of the wireless network.

Disable: The access point does not support 802.1x authentication for any wireless client. After successful wireless association with the access point, each client is allowed to access the network.

Supported: The access point supports 802.1x authentication only for clients initiating the 802.1x authentication process (the access point does not initiate 802.1x authentication). For clients initiating 802.1x, only those successfully authenticated are allowed to access the network. For those clients not initiating 802.1x, access to the network is allowed after successful wireless association with the access point.

Required: The access point enforces 802.1x authentication for 5-14 Advanced Configuration all associated wireless clients. If 802.1x authentication is not initiated by a client, the access point will initiate authentication. Only those clients successfully authenticated with 802.1x are allowed to access the network. When 802.1x is enabled, the broadcast and session key rotation intervals can also be configured.

Broadcast Key Refresh Rate: Sets the interval at which the broadcast keys are refreshed for stations using 802.1x dynamic keying. (Range: 0-1440 minutes; Default: 0 means disabled)

Session Key Refresh Rate: The interval at which the access point refreshes unicast session keys for associated clients.

(Range: 0-1440 minutes; Default: 0 means disabled)

802.1x Re-authentication Refresh Rate: The time period after which a connected client must be re-authenticated. During the re-authentication process of verifying the clients credentials on the RADIUS server, the client remains connected the network. Only if re-authentication fails is network access blocked. (Range: 0-65535 seconds; Default: 0 means disabled) CLI Commands for Local MAC Authentication Use the mac-authentication server command from the global configuration mode to enable local MAC authentication. Set the default for MAC addresses not in the local table using the address filter default command, then enter MAC addresses in the local table using the address filter entry command. To 5-15 System Configuration remove an entry from the table, use the address filter delete command. To display the current settings, use the show authentication command from the Exec mode.

5-18 Advanced Configuration Filter Control The access point can employ VLAN ID and network traffic frame filtering to control access to network resources and increase security. Native VLAN ID The VLAN ID assigned to wireless clients that are not assigned to a specific VLAN by RADIUS server configuration. VLAN Enables or disables VLAN tagging support on the SMC2552W-G. If enabled, the access point will tag traffic passing from wireless clients to the wired network with the VLAN ID associated with each client on the RADIUS server. Up to 16 VLAN IDs can be mapped to specific wireless clients, allowing users to remain within the same VLAN as they move around a campus site. This feature can also be used to control access to network resources from wireless clients, thereby improving security. A VLAN ID (1-4095) is assigned to a client after successful authentication using IEEE 802.1x and a central RADIUS server. 5-19 System Configuration The user VLAN IDs must be configured on the RADIUS server for each user authorized to access the network. If a user does not have a configured VLAN ID, the access point assigns the user to its own configured native VLAN ID. When setting up VLAN IDs for each user on the RADIUS server, be sure to use the RADIUS attributes and values as indicated in the following table. Number 64 65 81 RADIUS Attribute Tunnel-Type Tunnel-Medium-Type Tunnel-Private-Group Value VLAN (13) 802 VLANID

(1 to 4095 in hexadecimal) Note: The specific configuration of RADIUS server software is beyond the scope of this guide. Refer to the documentation provided with the RADIUS server software. When VLAN filtering is enabled, the access point must also have 802.1x authentication enabled and a RADIUS server configured. Wireless clients must also support 802.1x client software to be assigned to a specific VLAN. When VLAN filtering is disabled, the access point ignores the VLAN tags on any received frames. Local Bridge Filter Controls wireless-to-wireless communications between clients through the SMC2552W-G. However, it does not affect communications between wireless clients and the wired network.

Disable: Allows wireless-to-wireless communications between clients through the access point.

Enable: Blocks wireless-to-wireless communications between clients through the access point. 5-20 Advanced Configuration AP Management Filter Controls management access to the SMC2552W-G from wireless clients. Management interfaces include the web, Telnet, or SNMP.

5-23 System Configuration SNMP You can use a network management application such as SMCs EliteView to manage the SMC2552W-G via the Simple Network Management Protocol (SNMP) from a network management station. To implement SNMP management, the SMC2552W-G must have an IP address and subnet mask, configured either manually or dynamically. Once an IP address has been configured, appropriate SNMP communities and trap receivers should be configured. Community names are used to control management access to SNMP stations, as well as to authorize SNMP stations to receive trap messages from the access point. To communicate with the access point, a management station must first submit a valid community name for authentication. You therefore need to assign community names to specified users or user groups and set the access level. 5-24 Advanced Configuration SNMP Enables or disables SNMP management access and also enables the access point to send SNMP traps (notifications). SNMP management is enabled by default. Location A text string that describes the system location.

(Maximum length: 20 characters) Contact A text string that describes the system contact.

(Maximum length: 255 characters) Community Name (Read Only) Defines the SNMP community access string that has read-only access. Authorized management stations are only able to retrieve MIB objects. (Maximum length:

23 characters, case sensitive) Community Name (Read/Write) Defines the SNMP community access string that has read/write access. Authorized management stations are able to both retrieve and modify MIB objects. (Maximum length: 23 characters, case sensitive) Trap Destination IP Address Specifies the recipient of SNMP notifications. Enter the IP address or the host name. (Host Name:

1 to 20 characters) Trap Destination Community Name The community string sent with the notification operation. (Maximum length: 23 characters) 5-25 System Configuration CLI Commands for SNMP Use the snmp-server enable server command from the global configuration mode. To set read/write and read-only community names, use the snmp-server community command. Use the snmp-server location and snmp-server contact commands to indicate the physical location of the access point and define a system contact. The snmp-server host command defines a trap receiver host. To view the current SNMP settings, use the show snmp command.

5-26 Advanced Configuration Administration Changing the Password Management access to the web and CLI interface on the SMC2552W-G is controlled through a single user name and password. You can also gain additional access security by using control filters (see Filter Control on page 5-19). To protect access to the management interface, you need to configure an Administrators user name and password as soon as possible. If the user name and password are not configured, then anyone having access to the access point may be able to compromise access point and network security. Note: Pressing the Reset button on the back of the SMC2552W-G for more than five seconds resets the user name and password to the factory defaults. For this reason, we recommend that you protect the access point from physical access by unauthorized persons. Username The name of the user. The default name is admin.

6-21 6-22 Upgrading Firmware You can upgrade new SMC2552W-G software from a local file on the management workstation, or from an FTP or TFTP server. New software may be provided periodically on SMCs web site

(http://www.smc.com). After upgrading new software, you must reboot the SMC2552W-G to implement the new code. Until a reboot occurs, the SMC2552W-G will continue to run the software it was using before the upgrade started. Also note that rebooting the access point with new software will reset the configuration to the factory default settings. 5-28 Advanced Configuration Before upgrading new software, verify that the SMC2552W-G is connected to the network and has been configured with a compatible IP address and subnet mask. If you need to download from an FTP or TFTP server, take the following additional steps:

Obtain the IP address of the FTP or TFTP server where the access point software is stored.

If upgrading from an FTP server, be sure that you have an account configured on the server with a user name and password.

If VLANs are configured on the access point, determine the VLAN ID with which the FTP or TFTP server is associated, and then configure the management station with the same VLAN ID. If you are managing the access point from a wireless client, the VLAN ID for the the wireless client must be configured on a RADIUS server. Current version Version number of runtime code. 5-29 System Configuration Firmware Upgrade Local Downloads an operation code image file from the web management station to the access point using HTTP. Use the Browse button to locate the image file locally on the management station and click Start Upgrade to proceed.

IP Address: IP address or host name of FTP or TFTP server.

Username: The user ID used for login on an FTP server.

Password: The password used for login on an FTP server. Restore Factory Settings Click the Restore button to reset the configuration settings for the SMC2552W-G to the factory defaults and reboot the system. Note that all user configured information will be lost. You will have to re-enter the default user name (admin) to re-gain management access to this device. Reset Access Point Click the Reset button to reboot the system. Note: If you have upgraded system software, then you must reboot the SMC2552W-G to implement the new operation code. 5-30 Advanced Configuration CLI Commands for Downloading Software from a TFTP Server Use the copy tftp file command from the Exec mode and then specify the file type, name, and IP address of the TFTP server. When the download is complete, the dir command can be used to check that the new file is present in the access point file system. To run the new software, use the reset board command to reboot the access point. SMC-AP#copy tftp file 1. Application image 2. Config file 3.

The system clock can also be synchronized with a time server, so that all the messages sent to the Syslog server are stamped with the correct time and date. Enabling System Logging The SMC2552W-G supports a logging process that can control error messages saved to memory or sent to a Syslog server. The logged messages serve as a valuable tool for isolating access point and network problems. System Log Setup Enables the logging of error messages. Logging Host Enables the sending of log messages to a Syslog server host. Server Name/IP The IP address or name of a Syslog server. Logging Console Enables the logging of error messages to the console. 5-32 Advanced Configuration Logging Level Sets the minimum severity level for event logging. The system allows you to limit the messages that are logged by specifying a minimum severity level. The following table lists the error message levels from the most severe (Alert) to least severe

(Debug). The message levels that are logged include the specified minimum level up to the Alert level. Error Level Alerts Critical Error Warning Notice Informational Debug Description Immediate action needed Critical conditions (e.g., memory allocation, or free memory error - resource exhausted) Error conditions (e.g., invalid input, default used) Warning conditions (e.g., return false, unexpected return) Normal but significant condition, such as cold start Informational messages only Debugging messages Note: The access point error log can be viewed using the Event Logs window in the Status section (page 5-62).The Event Logs window displays the last 128 messages logged in chronological order, from the newest to the oldest. Log messages saved in the access points memory are erased when the device is rebooted. CLI Commands for System Logging To enable logging on the access point, use the logging on command from the global configuration mode. The logging level command sets the minimum level of message to log. Use the logging console command to enable logging to the console. Use the logging host command to specify up to four Syslog servers. The CLI also allows the logging facility-type command to set the facility-type 5-33 System Configuration number to use on the Syslog server.

Configuring SNTP Simple Network Time Protocol (SNTP) allows the SMC2552W-G to set its internal clock based on periodic updates from a time server (SNTP or NTP). Maintaining an accurate time on the access point enables the system log to record meaningful dates and times for event entries. If the clock is not set, the access point will only record the time from the factory default set at the last bootup. The SMC2552W-G acts as an SNTP client, periodically sending time synchronization requests to specific time servers. You can configure up to two time server IP addresses. The access point will attempt to poll each server in the configured sequence. 5-34 Advanced Configuration SNTP Server Configures the access point to operate as an SNTP client. When enabled, at least one time server IP address must be specified.

Primary Server: The IP address of an SNTP or NTP time server that the access point attempts to poll for a time update.

Secondary Server: The IP address of a secondary SNTP or NTP time server. The access point first attempts to update the time from the primary server; if this fails it attempts an update from the secondary server. Note: The SMC2552W-G also allows you to disable SNTP and set the system clock manually using the CLI. Set Time Zone SNTP uses Coordinated Universal Time (or UTC, formerly Greenwich Mean Time, or GMT) based on the time at the Earths prime meridian, zero degrees longitude. To display a time corresponding to your local time, you must indicate the number of hours your time zone is located before (east) or after

(west) UTC. Enable Daylight Saving The access point provides a way to automatically adjust the system clock for Daylight Savings Time changes. To use this feature you must define the month and date to begin and to end the change from standard time. During this period the system clock is set back by one hour. CLI Commands for SNTP To enable SNTP support on the access point, from the global configuration mode specify SNTP server IP addresses using the sntp-server ip command, then use the sntp-server enable command to enable the service. Use the sntp-server timezone command to set the time zone for your location, and the sntp-server daylight-saving command to set 5-35 System Configuration daylight savings. To view the current SNTP settings, use the show sntp command.

6-29 6-30 5-36 Radio Interface Radio Interface The IEEE 802.11b and 802.11g interface includes configuration options for radio signal characteristics and wireless security features. The access point can operate in three modes, IEEE 802.11b only, 802.11g only, or a mixed 802.11b/g mode. Also note that 802.11g is backward compatible with 802.11b. These interfaces are configured independently under the following web pages:

Radio Interface : 802.11b/g Note: The radio channel settings for the SMC2552W-G are limited by local regulations, which determine the number of channels that are available. 5-37 System Configuration Radio Settings (802.11g) The IEEE 802.11g standard operates within the 2.4 GHz band at up to 54 Mbps. Also note that because the IEEE 802.11g standard is an extension of the IEEE 802.11b standard, it allows clients with 802.11b wireless network cards to associate to an 802.11g access point. Enable Enables radio communications on the SMC2552W-G.

(Default: Enabled) 5-38 Radio Interface Radio Channel The radio channel that the access point uses to communicate with wireless clients. When multiple access points are deployed in the same area, set the channel on neighboring access points at least four channels apart to avoid interference with each other. For example, in the United States you can deploy up to four access points in the same area (e.g., channels 1, 6, 11). Also note that the channel for wireless clients is automatically set to the same as that used by the access point to which it is linked. (Range: 1-11; Default: 1) Auto Channel Select Enables the access point to automatically select an unoccupied radio channel.

(Default: Enabled) SSID Broadcast The SSID broadcast can be disabled to prevent access to clients without a pre-configured SSID. When disabled, the access point will not include its SSID in beacon messages. Nor will it respond to probe requests from clients that do not include the correct SSID. (Default: Enabled) Select Antenna Mode Specifies whether the antenna used will be automatically selected based on best signal reception (i.e., Diversity mode), or will be fixed to use an optional high-gain antenna attached to the right side of the access point.

(Default: Diversity) Working Mode The access point can be configured to support both 802.11b and 802.11g clients simultaneously, 802.11b clients only, or 802.11g clients only. (Default: 802.11b and 802.11g) Transmit Power Adjusts the power of the radio signals transmitted from the access point. The higher the transmission power, the farther the transmission range. Power selection is not just a trade off between coverage area and maximum supported clients. You also have to ensure that high-power signals do not 5-39 System Configuration interfere with the operation of other radio devices in the service area. (Options: 100%, 50%, 25%, 12%, minimum; Default: 100%) Maximum Station Data Rate The maximum data rate at which a client can connect to the access point. The maximum transmission distance is affected by the data rate. The lower the data rate, the longer the transmission distance. (Options: 54, 48, 36, 24 Mbps; Default: 54 Mbps) Beacon Interval The rate at which beacon signals are transmitted from the access point. The beacon signals allow wireless clients to maintain contact with the access point. They may also carry power-management information. (Range: 20-1000 TUs; Default: 100 TUs) Data Beacon Rate The rate at which stations in sleep mode must wake up to receive broadcast/multicast transmissions. Known also as the Delivery Traffic Indication Map (DTIM) interval, it indicates how often the MAC layer forwards broadcast/multicast traffic, which is necessary to wake up stations that are using Power Save mode. The default value of 2 indicates that the access point will save all broadcast/multicast frames for the Basic Service Set (BSS) and forward them after every second beacon. Using smaller DTIM intervals delivers broadcast/multicast frames in a more timely manner, causing stations in Power Save mode to wake up more often and drain power faster. Using higher DTIM values reduces the power used by stations in Power Save mode, but delays the transmission of broadcast/multicast frames.

(Range: 1-255 beacons; Default: 2 beacons) RTS Threshold Sets the packet size threshold at which a Request to Send (RTS) signal must be sent to a receiving station prior to the sending station starting communications. The access point sends RTS frames to a receiving station to negotiate the 5-40 Radio Interface sending of a data frame. After receiving an RTS frame, the station sends a CTS (clear to send) frame to notify the sending station that it can start sending data. If the RTS threshold is set to 0, the access point never sends RTS signals. If set to 2347, the access point always sends RTS signals. If set to any other value, and the packet size equals or exceeds the RTS threshold, the RTS/CTS (Request to Send /

Clear to Send) mechanism will be enabled. The access points contending for the medium may not be aware of each other. The RTS/CTS mechanism can solve this Hidden Node Problem. (Range: 0-2347 bytes: Default: 2347 bytes) CLI Commands for the 802.11g Wireless Interface From the global configuration mode, enter the interface wireless g command to access the 802.11g radio interface. Set the interface SSID using the ssid command and, if required, configure a name for the interface using the description command. You can also use the no ssid-broadcast command to stop sending the SSID in beacon messages. Select a radio channel or set selection to Auto using the channel command. Set any other parameters as 5-41 System Configuration required. To view the current 802.11g radio settings, use the show interface wireless g command.

5-43 System Configuration Security The SMC2552W-G is configured by default as an open system, which broadcasts a beacon signal including the configured SSID. Wireless clients can read the SSID from the beacon, and automatically reset their SSID to allow immediate connection to the nearest access point. To improve wireless network security, you have to implement two main functions:

Authentication: It must be verified that clients attempting to connect to the network are authorized users.

Traffic Encryption: Data passing between the access point and clients must be protected from interception and evesdropping. For a more secure network, the access point can implement one or a combination of the following security mechanisms:

Wired Equivalent Privacy (WEP)

IEEE 802.1x

Wireless MAC address filtering

Wi-Fi Protected Access (WPA) page 5-46 page 5-14 page 5-12 page 5-51 5-44 Radio Interface The security mechanisms that may be employed depend on the level of security required, the network and management resources available, and the software support provided on wireless clients. A summary of wireless security considerations is listed in the following table. Security Mechanism Client Support Implementation Considerations WEP WEP with 802.1x Built-in support on all 802.11b and 802.11g devices Requires 802.1x client support in system or by add-in software

(native support provided in Windows XP) WPA PSK Mode Requires WPA-enabled system and network card driver

(native support provided in Windows XP) 5-45 System Configuration Wired Equivalent Privacy (WEP) WEP provides a basic level of security, preventing unauthorized access to the network and encrypting data transmitted between wireless clients and the access point. WEP uses static shared keys (fixed-length hexadecimal or alphanumeric strings) that are manually distributed to all clients that want to use the network. WEP is the security protocol initially specified in the IEEE 802.11 standard for wireless communications. Unfortunately, WEP has been found to be flawed. For more robust wireless security, the SMC2552W-G provides Wi-Fi Protected Access (WPA) for improved data encryption and user authentication. Setting up shared keys enables the basic IEEE 802.11 Wired Equivalent Privacy (WEP) on the access point to prevent unauthorized access to the network. If you choose to use WEP shared keys instead of an open system, be sure to define at least one static WEP key for user authentication and data encryption. Also, be sure that the WEP shared keys are the same for each client in the wireless network. 5-46 Radio Interface Authentication Type Setup Sets the access point to communicate as an open system that accepts network access attempts from any client, or with clients using pre-configured static shared keys.

Open System: Select this option if you plan to use WPA or 802.1x as a security mechanism. If you dont set up any other security mechanism on the access point, the network has no protection and is open to all users. This is the default setting.

Shared Key: Sets the access point to use WEP shared keys. If this option is selected, you must configure at least one key on the access point and all clients. Note: To use 802.1x on wireless clients requires a network card driver and 802.1x client software that supports the EAP authentication type that you want to use. Windows XP provides native WPA support, other systems require additional software. Wired Equivalent Privacy (WEP) Setup Enable or disable the access point to use WEP shared keys for data encryption. If this option is selected, you must configure at least one key on the access point and all clients. (Default: Disable) Note: Although WEP keys are not needed for WPA, you must enable WEP encryption through the web or CLI in order to enable all types of encryption in the access point. Shared Key Setup Select 64 Bit, 128 Bit, or 152 Bit key length. Note that the same size of encryption key must be supported on all wireless clients. (Default: 128 Bit) 5-47 System Configuration Key Type Select the preferred method of entering WEP encryption keys on the access point and enter up to four keys:

Hexadecimal: Enter keys as 10 hexadecimal digits (0 to 9 and A to F) for 64 bit keys, 26 hexadecimal digits for 128 bit keys, or 32 hexadecimal digits for 152 bit keys.

Alphanumeric: Enter keys as 5 alphanumeric characters for 64 bit keys, 13 alphanumeric characters for 128 bit keys, or 16 alphanumeric characters for 152 bit keys.

Transmit Key Select: Selects the key number to use for encryption. If the clients have all four keys configured to the same values, you can change the encryption key to any of the four settings without having to update the client keys. Note: Key index and type must match that configured on the clients. The configuration settings for WEP are summarized below:

6-68 6-83 6-84 6-89 6-51 6-57 5-50 Radio Interface Wi-Fi Protected Access (WPA) WPA employs a combination of several technologies to provide an enhanced security solution for 802.11 wireless networks. The SMC2552W-G supports the following WPA components and features:

IEEE 802.1x and the Extensible Authentication Protocol (EAP):

WPA employs 802.1x as its basic framework for user authentication and dynamic key management. The 802.1x client and RADIUS server should use an appropriate EAP typesuch as EAP-TLS (Transport Layer Security), EAP-TTLS (Tunneled TLS), or PEAP (Protected EAP)for strongest authentication. Working together, these protocols provide mutual authentication between a client, the access point, and a RADIUS server that prevents users from accidentally joining a rogue network. Only when a RADIUS server has authenticated a users credentials will encryption keys be sent to the access point and client. 5-51 System Configuration Note: To implement WPA on wireless clients requires a WPA-enabled network card driver and 802.1x client software that supports the EAP authentication type that you want to use. Windows XP provides native WPA support, other systems require additional software. Temporal Key Integrity Protocol (TKIP): WPA specifies TKIP as the data encryption method to replace WEP. TKIP avoids the problems of WEP static keys by dynamically changing data encryption keys. Basically, TKIP starts with a master (temporal) key for each user session and then mathematically generates other keys to encrypt each data packet. TKIP provides further data encryption enhancements by including a message integrity check for each packet and a re-keying mechanism, which periodically changes the master key. WPA Pre-Shared Key (PSK) Mode: For enterprise deployment, WPA requires a RADIUS authentication server to be configured on the wired network. However, for small office networks that may not have the resources to configure and maintain a RADIUS server, WPA provides a simple operating mode that uses just a pre-shared password for network access. The Pre-Shared Key mode uses a common password for user authentication that is manually entered on the access point and all wireless clients. The PSK mode uses the same TKIP packet encryption and key management as WPA in the enterprise, providing a robust and manageable alternative for small networks. Mixed WPA and WEP Client Support: WPA enables the access point to indicate its supported encryption and authentication mechanisms to clients using its beacon signal. WPA-compatible clients can likewise respond to indicate their WPA support. This enables the access point to determine which clients are using WPA security and which are using legacy WEP. The access point uses TKIP unicast data encryption keys for WPA clients and WEP unicast keys for WEP clients. The global encryption key for 5-52 Radio Interface multicast and broadcast traffic must be the same for all clients, therefore it restricts encryption to a WEP key. Advanced Encryption Standard (AES) Support: WPA specifies AES encryption as an optional alternative to TKIP and WEP. AES provides very strong encryption using a completely different ciphering algorithm to TKIP and WEP. The developing IEEE 802.11i wireless security standard has specified AES as an eventual replacement for TKIP and WEP. However, because of the difference in ciphering algorithms, AES requires new hardware support in client network cards that is currently not widely available. The access point includes AES support as a future security enhancement. The WPA configuration parameters are described below:

WPA Configuration Mode The access point can be configured to allow only WPA-enabled clients to access the network, or also allow clients only capable of supporting WEP. WPA Key Management WPA can be configured to work in an enterprise environment using IEEE 802.1x and a RADIUS server for user authentication. For smaller networks, WPA can be enabled using a common pre-shared key for client authentication with the access point.

WPA authentication over 802.1x: The WPA enterprise mode that uses IEEE 802.1x to authenticate users and to dynamically distribute encryption keys to clients.

WPA Pre-shared Key: The WPA mode for small networks that uses a common password string that is manually distributed. If this mode is selected, be sure to also specify the key string. 5-53 System Configuration Multicast Cipher Mode Selects an encryption method for the global key used for multicast and broadcast traffic, which is supported by all wireless clients.

WEP: WEP is the first generation security protocol used to encrypt data crossing the wireless medium using a fairly short key. Communicating devices must use the same WEP key to encrypt and decrypt radio signals. WEP has many security flaws, and is not recommended for transmitting highly-sensitive data.

TKIP: TKIP provides data encryption enhancements including per-packet key hashing (that is, changing the encryption key on each packet), a message integrity check, an extended initialization vector with sequencing rules, and a re-keying mechanism.

AES: AES has been designated by the National Institute of Standards and Technology as the successor to the Data Encryption Standard (DES) encryption algorithm, and will be used by the U.S. government for encrypting all sensitive, nonclassified information. Because of its strength, and resistance to attack, AES is also being incorporated as part of the 802.11 standard. WPA Pre-Shared Key Type If the WPA pre-shared-key mode is used, all wireless clients must be configured with the same key to communicate with the access point.

Hexadecimal: Enter a key as a string of 64 hexadecimal numbers.

Alphanumeric: Enter a key as an easy-to-remember form of letters and numbers. The string must be from 8 to 63 characters, which can include spaces. 5-54 Radio Interface The configuration settings for WPA are summarized below:

WPA pre-shared key only WPA over 802.1x Authentication Type: Open System WEP (encryption): Enable1 WPA clients only: Enable WPA Mode: Pre-shared-key Multicast Cipher: WEP/TKIP/AES2 WPA PSK Type -

For example, use the CLI encryption command to set Encryption = 64, 128 or 152, thus enabling encryption (i.e., all types of encryption) in the access point. 2: Do not use WEP unless the access point must support both WPA and WEP clients. 3: See Authentication (page 5-12) 4: See Radius (page 5-9) CLI Commands for WPA Pre-shared Key Security From the 802.11g interface configuration mode, use the authentication command to set the access point to Open System. Use the WEP encryption command to enable all types of encryption. To enable WPA to be required for all clients, use the wpa-clients command. Use the wpa-mode command to enable the Pre-shared Key mode. To enter a key value, use the wpa-psk-type command to specify a hexadecimal or alphanumeric key, and then use the wpa-preshared-key command to define the key. Then disable 802.1x and MAC authentication. To view the current 802.11g security settings, use 5-55 System Configuration the show interface wireless g command (not shown in example). 6-68 SMC-AP(config)#interface wireless g Enter Wireless configuration commands, one per line. 6-83 SMC-AP(if-wireless g)#authentication open 6-84 SMC-AP(if-wireless g)#encryption 128 6-90 SMC-AP(if-wireless g)#wpa-clients required 6-92 SMC-AP(if-wireless g)#wpa-mode pre-shared-key 6-94 SMC-AP(if-wireless g)#wpa-psk-type alphanumeric SMC-AP(if-wireless g)#wpa-preshared-key ASCII asecret 6-93 SMC-AP(if-wireless g)#end SMC-AP(config)#no 802.1x SMC-AP(config)#no mac-authentication 6-51 6-57 CLI Commands for WPA over 802.1x Security From the 802.11g interface configuration mode, use the authentication command to set the access point to Open System.

5-59 System Configuration Station Status The Station Status window shows the wireless clients currently associated with the SMC2552W-G. The Station Configuration page displays basic connection information for all associated stations as described below. Note that this page is automatically refreshed every five seconds.

Station Address: The MAC address of the wireless client.

Authenticated: Shows if the station has been authenticated. The two basic methods of authentication supported for 802.11 wireless networks are open system and shared key. Open-system authentication accepts any client attempting to connect to the access point without verifying its identity. The shared-key approach uses Wired Equivalent Privacy (WEP) to verify client identity by distributing a shared key to stations before attempting authentication.

Associated: Shows if the station has been successfully associated with the access point. Once authentication is completed, stations can associate with the current access point, or reassociate with a new access point. The association 5-60 Status Information procedure allows the wireless system to track the location of each mobile client, and ensure that frames destined for each client are forwarded to the appropriate access point.

Forwarding Allowed: Shows if the station has passed 802.1x authentication and is now allowed to forward traffic to the access point.

Key Type: Displays Open System or Shared Key. CLI Commands for Displaying Station Status To view status of clients currently associated with the access point, use the show station command from the Exec mode.

5-61 System Configuration Event Logs The Event Logs window shows the log messages generated by the access point and stored in memory. The Event Logs table displays the following information:

Log Time: The time the log message was generated.

Event Level: The logging level associated with this message. For a description of the various levels, see logging level on page 5-32.

Event Message: The content of the log message. Error Messages An example of a logged error message is:

Station Failed to authenticate (unsupported algorithm). This message may be caused by any of the following conditions:

Access point was set to Open Authentication, but a client sent an authentication request frame with a Shared key.

Access point was set to Shared Key Authentication, but a client sent an authentication frame for Open System. 5-62 Status Information

WEP keys do not match: When the access point uses Shared Key Authentication, but the key used by client and access point are not the same, the frame will be decrypted incorrectly, using the wrong algorithm and sequence number. CLI Commands for Displaying the Event Logs From the global configuration mode, use the show logging command. SMC-AP#show logging 6-27 Logging Information

SMC-AP#

Note: Log messages are not displayed in the CLI. 5-63 System Configuration 5-64 Chapter 6 Command Line Interface Using the Command Line Interface Accessing the CLI When accessing the management interface for the SMC2552W-G over a direct connection to the console port, or via a Telnet connection, the access point can be managed by entering command keywords and parameters at the prompt. Using the access points command-line interface (CLI) is very similar to entering commands on a UNIX system. Console Connection To access the access point through the console port, perform these steps:

1. At the console prompt, enter the user name and password.

(The default user name is admin and the default password is smcadmin.) When the user name is entered, the CLI displays the SMC Enterprise AP# prompt. 2. Enter the necessary commands to complete your desired tasks. 3. When finished, exit the session with the exit command. 6-1 Command Line Interface After connecting to the system through the console port, the login screen displays:

Username: admin Password: smcadmin SMC Enterprise AP#

Note: Command examples shown later in this chapter abbreviate the console prompt to SMC-AP for simplicity. Telnet Connection Telnet operates over the IP transport protocol. In this environment, your management station and any network device you want to manage over the network must have a valid IP address. Valid IP addresses consist of four numbers, 0 to 255, separated by periods. Each address consists of a network portion and host portion. For example, if the access point cannot acquire an IP address from a DHCP server, the default IP address used by the access point, 192.168.2.2, consists of a network portion

(192.168.2) and a host portion (2). To access the access point through a Telnet session, you must first set the IP address for the access point, and set the default gateway if you are managing the access point from a different IP subnet. For example:

SMC-AP#configure SMC-AP(config)#interface ethernet SMC-AP(if-ethernet)#ip address 10.1.0.1 255.255.255.0 10.1.0.254 SMC-AP(if-ethernet)#

If your corporate network is connected to another network outside your office or to the Internet, you need to apply for a registered IP address. However, if you are attached to an isolated network, then you can use any IP address that matches the network segment to which you are attached. 6-2 Entering Commands After you configure the access point with an IP address, you can open a Telnet session by performing these steps. 1. From the remote host, enter the Telnet command and the IP address of the device you want to access. 2. At the prompt, enter the user name and system password. The CLI will display the SMC Enterprise AP# prompt to show that you are using executive access mode (i.e., Exec). 3. Enter the necessary commands to complete your desired tasks. 4. When finished, exit the session with the quit or exit command. After entering the Telnet command, the login screen displays:

Username: admin Password: smcadmin SMC-AP#

Note: You can open up to four sessions to the device via Telnet. Entering Commands This section describes how to enter CLI commands. Keywords and Arguments A CLI command is a series of keywords and arguments. Keywords identify a command, and arguments specify configuration parameters. For example, in the command show interfaces ethernet, show and interfaces are keywords, and ethernet is an argument that specifies the interface type. 6-3 Command Line Interface You can enter commands as follows:

To enter a simple command, enter the command keyword.

To enter commands that require parameters, enter the required parameters after the command keyword. For example, to set a password for the administrator, enter:

SMC Enterprise AP(config)#username smith Minimum Abbreviation The CLI will accept a minimum number of characters that uniquely identify a command. For example, the command configure can be entered as con. If an entry is ambiguous, the system will prompt for further input. Command Completion If you terminate input with a Tab key, the CLI will print the remaining characters of a partial keyword up to the point of ambiguity. In the configure example, typing con followed by a tab will result in printing the command up to configure. Getting Help on Commands You can display a brief description of the help system by entering the help command. You can also display command syntax by following a command with the ? character to list keywords or parameters. Showing Commands If you enter a ? at the command prompt, the system will display the first level of keywords for the current configuration mode

(Exec, Global Configuration, or Interface). You can also display a 6-4 Entering Commands list of valid keywords for a specific command. For example, the command show ? displays a list of possible show commands:

SMC-AP#show?

authentication Show Authentication parameters bootfile Show bootfile name filters Show filters hardware Show hardware version history Display the session history interface Show interface information line TTY line information logging Show the logging buffers radius Show radius server snmp Show snmp statistics sntp Show sntp statistics station Show 802.11 station table system Show system information version Show system version SMC-AP#show The command show interface? will display the following information:

SMC-AP#show interface?

ethernet Show Ethernet interface wireless Show wireless interface

<cr>

SMC-AP#show interface Partial Keyword Lookup If you terminate a partial keyword with a question mark, alternatives that match the initial letters are provided. (Remember not to leave a space between the command and question mark.) For example s? shows all the keywords starting with s. SMC-AP#show s?

snmp sntp station system SMC-AP#show s 6-5 Command Line Interface Negating the Effect of Commands For many configuration commands you can enter the prefix keyword no to cancel the effect of a command or reset the configuration to the default value. For example, the logging command will log system messages to a host server. To disable logging, specify the no logging command. This guide describes the negation effect for all applicable commands. Using Command History The CLI maintains a history of commands that have been entered. You can scroll back through the history of commands by pressing the up arrow key. Any command displayed in the history list can be executed again, or first modified and then executed. Using the show history command displays a longer list of recently executed commands. Understanding Command Modes The command set is divided into Exec and Configuration classes. Exec commands generally display information on system status or clear statistical counters. Configuration commands, on the other hand, modify interface parameters or enable certain functions. These classes are further divided into different modes. Available commands depend on the selected mode. You can always enter a question mark ? at the prompt to display a list of the commands available for the current mode. The command classes and associated modes are displayed in the following table:

Class Exec Configuration Mode Privileged Global Interface-ethernet Interface-wireless 6-6 Entering Commands Exec Commands When you open a new console session on access point, the system enters Exec command mode. Only a limited number of the commands are available in this mode. You can access all other commands only from the configuration mode. To access Exec mode, open a new console session with the user name admin. The command prompt displays as SMC Enterprise AP#

for Exec mode. Username: admin Password: [system login password]

SMC-AP#

Configuration Commands Configuration commands are used to modify access point settings. These commands modify the running configuration and are saved in memory. The configuration commands are organized into three different modes:

Global Configuration - These commands modify the system level configuration, and include commands such as username and password.

Interface-Ethernet Configuration - These commands modify the Ethernet port configuration, and include command such as dns and ip.

Interface-Wireless Configuration - These commands modify the wireless port configuration, and include command such as ssid and authentication. 6-7 Command Line Interface To enter the Global Configuration mode, enter the command configure in Exec mode. The system prompt will change to SMC Enterprise AP(config)# which gives you access privilege to all Global Configuration commands. SMC-AP#configure SMC-AP(config)#

To enter Interface mode, you must enter the interface ethernet, or interface wireless g command while in Global Configuration mode. The system prompt will change to SMC Enterprise AP(if-ethernet)#, or SMC Enterprise AP(if-wireless) indicating that you have access privileges to the associated commands. You can use the end command to return to the Exec mode. SMC-AP(config)#interface ethernet SMC-AP(if-ethernet)#

Command Line Processing Commands are not case sensitive. You can abbreviate commands and parameters as long as they contain enough letters to differentiate them from any other currently available commands or parameters. You can use the Tab key to complete partial commands, or enter a partial command followed by the ?

character to display a list of possible matches. You can also use the following editing keystrokes for command-line processing:

Keystroke Ctrl-A Ctrl-B Ctrl-C Ctrl-E Ctrl-F Ctrl-K Ctrl-L Ctrl-N Function Shifts cursor to start of command line. Shifts cursor to the left one character. Terminates a task and displays the command prompt. Shifts cursor to end of command line. Shifts cursor to the right one character. Deletes from cursor to the end of the command line. Repeats current command line on a new line. Enters the next command line in the history buffer. 6-8 Entering Commands Keystroke Ctrl-P Ctrl-R Ctrl-U Ctrl-W Esc-B Esc-D Esc-F Delete key or backspace key Function Shows the last command. Repeats current command line on a new line. Deletes the entire line. Deletes the last word typed. Moves the cursor backward one word. Deletes from the cursor to the end of the word. Moves the cursor forward one word. Erases a mistake when entering a command. 6-9 Command Line Interface Command Groups The system commands can be broken down into the functional groups shown below.

6-49 Command Line Interface 802.1x Port Authentication The access point supports IEEE 802.1x access control for wireless clients. This control feature prevents unauthorized access to the network by requiring a 802.1x client application to submit a user name and password for authentication. Client authentication is then verified via by a RADIUS server using EAPOL (Extensible Authentication Protocol Over LAN) before the access point grants client access to the network. Command Function 802.1x Configures 802.1x as disabled, supported, or required 802.1x broadcast-key-

refresh-rate Sets the interval at which the primary broadcast keys are refreshed for stations using 802.1x dynamic keying 802.1x session-key-

supported - Authenticates clients that initiate the 802.1x authentication process. Uses standard 802.11 authentication for all others.

required - Requires 802.1x authentication for all clients. Default Setting Disabled Command Mode Global Configuration Command Usage

When 802.1x is disabled, the access point does not support 802.1x authentication for any station. After successful 802.11 association, each client is allowed to access the network.

When 802.1x is supported, the access point supports 802.1x authentication only for clients initiating the 802.1x 6-51 Command Line Interface authentication process (i.e., the access point does NOT initiate 802.1x authentication). For stations initiating 802.1x, only those stations successfully authenticated are allowed to access the network. For those stations not initiating 802.1x, access to the network is allowed after successful 802.11 association.

When 802.1x is required, the access point enforces 802.1x authentication for all 802.11 associated stations. If 802.1x authentication is not initiated by the station, the access point will initiate authentication. Only those stations successfully authenticated with 802.1x are allowed to access the network.

802.1x does not apply to the 10/100Base-TX port. Example SMC-AP(config)#802.1x supported SMC-AP(config)#

802.1x broadcast-key-refresh-rate This command sets the interval at which the broadcast keys are refreshed for stations using 802.1x dynamic keying. Syntax 802.1x broadcast-key-refresh-rate <rate>

rate - The interval at which the access point rotates broadcast keys. (Range: 0 - 1440 minutes) Default Setting 0 (Disabled) Command Mode Global Configuration 6-52 802.1x Port Authentication Command Usage

The access point uses EAPOL (Extensible Authentication Protocol Over LANs) packets to pass dynamic unicast session and broadcast keys to wireless clients. The 802.1x broadcast-key-refresh-rate command specifies the interval after which the broadcast keys are changed. The 802.1x session-key-refresh-rate command specifies the interval after which unicast session keys are changed.

Dynamic broadcast key rotation allows the access point to generate a random group key and periodically update all key-management capable wireless clients. Example SMC-AP(config)#802.1x broadcast-key-refresh-rate 5 SMC-AP(config)#

802.1x session-key-refresh-rate This command sets the interval at which unicast session keys are refreshed for associated stations using dynamic keying. Syntax 802.1x session-key-refresh-rate <rate>

rate - The interval at which the access point refreshes a session key. (Range: 0 - 1440 minutes) Default Setting 0 (Disabled) Command Mode Global Configuration Command Usage Session keys are unique to each client, and are used to authenticate a client connection, and correlate traffic passing between a specific client and the access point. 6-53 Command Line Interface Example SMC-AP(config)#802.1x session-key-refresh-rate 5 SMC-AP(config)#

802.1x session-timeout This command sets the time period after which a connected client must be re-authenticated. Use the no form to disable 802.1x re-authentication. Syntax 802.1x session-timeout <seconds>

speed This command configures the maximum data rate at which a station can connect to the access point. Syntax speed <speed>

speed - Maximum access speed allowed for wireless clients.

(Options: 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, 54 Mbps) Default Setting 54 Mbps Command Mode Interface Configuration (Wireless) Command Usage The maximum transmission distance is affected by the data rate. The lower the data rate, the longer the transmission distance. Please refer to the table for maximum distances on page A-4. Example SMC-AP(if-wireless g)#speed 6 SMC-AP(if-wireless g)#

6-78 Interface Commands channel This command configures the radio channel through which the access point communicates with wireless clients. Syntax channel <channel | auto>

channel - Manually sets the radio channel used for communications with wireless clients. (Range: 802.11g - 1 to 11)

auto - Automatically selects an unoccupied channel (if available). Otherwise, the lowest channel is selected. Default Setting Automatic channel selection Command Mode Interface Configuration (Wireless) Command Usage

The available channel settings are limited by local regulations, which determine the number of channels that are available.

When multiple access points are deployed in the same area, be sure to choose a channel separated by at least five channels for 802.11g to avoid having the channels interfere with each other. You can deploy up to three access points in the same area for 802.11g (e.g., channels 1, 6, 11).

For most wireless adapters, the channel for wireless clients is automatically set to the same as that used by the access point to which it is linked. Example SMC-AP(if-wireless g)#channel 1 SMC-AP(if-wireless g)#

6-79 Command Line Interface ssid This command configures the service set identifier (SSID). Syntax ssid string string - The name of a basic service set supported by the access point. (Range: 1 - 32 characters) Default Setting smc Command Mode Interface Configuration (Wireless) Command Usage Clients that want to connect to the wireless network via an access point must set their SSIDs to the same as that of the access point. Example SMC-AP(if-wireless g)#ssid RD-AP#3 SMC-AP(if-wireless g)#

beacon-interval This command configures the rate at which beacon signals are transmitted from the access point. Syntax beacon-interval <interval>

interval - The rate for transmitting beacon signals.

(Range: 20-1000 milliseconds) Default Setting 100 6-80 Interface Commands Command Mode Interface Configuration (Wireless) Command Usage The beacon signals allow wireless clients to maintain contact with the access point. They may also carry power-management information. Example SMC-AP(if-wireless g)#beacon-interval 150 SMC-AP(if-wireless g)#

dtim-period This command configures the rate at which stations in sleep mode must wake up to receive broadcast/multicast transmissions. Syntax dtim-period <interval>

interval - Interval between the beacon frames that transmit broadcast or multicast traffic. (Range: 1-255 beacon frames) Default Setting 2 Command Mode Interface Configuration (Wireless) Command Usage

The Delivery Traffic Indication Map (DTIM) packet interval value indicates how often the MAC layer forwards broadcast/multicast traffic. This parameter is necessary to wake up stations that are using Power Save mode.

The DTIM is the interval between two synchronous frames with broadcast/multicast information. The default value of 2 6-81 Command Line Interface indicates that the access point will save all broadcast/

multicast frames for the Basic Service Set (BSS) and forward them after every second beacon.

Using smaller DTIM intervals delivers broadcast/multicast frames in a more timely manner, causing stations in Power Save mode to wake up more often and drain power faster. Using higher DTIM values reduces the power used by stations in Power Save mode, but delays the transmission of broadcast/multicast frames. Example SMC-AP(if-wireless g)#dtim-period 100 SMC-AP(if-wireless g)#

fragmentation-length This command configures the minimum packet size that can be fragmented when passing through the access point. Syntax fragmentation-length <length>

length - Minimum packet size for which fragmentation is allowed. (Range: 256-2346 bytes) Default Setting 2346 Command Mode Interface Configuration (Wireless) Command Usage

If the packet size is smaller than the preset Fragment size, the packet will not be segmented.

Fragmentation of the PDUs (Package Data Unit) can increase the reliability of transmissions because it increases the probability of a successful transmission due to smaller frame size. If there is significant interference present, or 6-82 Interface Commands collisions due to high network utilization, try setting the fragment size to send smaller fragments. This will speed up the retransmission of smaller frames. However, it is more efficient to set the fragment size larger if very little or no interference is present because it requires overhead to send multiple frames. Example SMC-AP(if-wireless g)#fragmentation-length 512 SMC-AP(if-wireless g)#

rts-threshold This command sets the packet size threshold at which a Request to Send (RTS) signal must be sent to the receiving station prior to the sending station starting communications. Syntax rts-threshold <threshold>

threshold - Threshold packet size for which to send an RTS.

(Range: 0-2347 bytes) Default Setting 2347 Command Mode Interface Configuration (Wireless) Command Usage

If the threshold is set to 0, the access point never sends RTS signals. If set to 2347, the access point always sends RTS signals. If set to any other value, and the packet size equals or exceeds the RTS threshold, the RTS/CTS

(Request to Send / Clear to Send) mechanism will be enabled.

The access point sends RTS frames to a receiving station to negotiate the sending of a data frame. After receiving an 6-83 Command Line Interface RTS frame, the station sends a CTS frame to notify the sending station that it can start sending data.

Access points contending for the wireless medium may not be aware of each other. The RTS/CTS mechanism can solve this Hidden Node problem. Example SMC-AP(if-wireless g)#rts-threshold 256 SMC-AP(if-wireless g)#

authentication This command defines the 802.11 authentication type allowed by the access point. Syntax authentication <open | shared>

open - Accepts the client without verifying its identity using a shared key.

shared - Authentication is based on a shared key that has been distributed to all stations. Default Setting open Command Mode Interface Configuration (Wireless) Command Usage

Shared key authentication can only be used when WEP is enabled with the encryption command, and at least one static WEP key has been defined with the key command.

When using WPA or 802.1x for authentication and dynamic keying, the access point must be set to open. 6-84 Interface Commands Example SMC-AP(if-wireless g)#authentication shared SMC-AP(if-wireless g)#

Related Commands encryption (page 6-85) key (page 6-86) encryption This command defines whether or not WEP encryption is used to provide privacy for wireless communications. Use the no form to disable encryption. Syntax encryption <key-length>

no encryption key-length - Size of encryption key.

(Options: 64, 128, or 152 bits) Default Setting disabled Command Mode Interface Configuration (Wireless) Command Usage

Wired Equivalent Privacy (WEP) is implemented in this device to prevent unauthorized access to your wireless network. For more secure data transmissions, enable WEP with this command, and set at least one static WEP key with the key command.

The WEP settings must be the same on each client in your wireless network.

The encryption length specified in the encryption command and the key command must match. 6-85 Command Line Interface

Note that WEP protects data transmitted between wireless nodes, but does not protect any transmissions over your wired network or over the Internet. Example SMC-AP(if-wireless g)#encryption 128 SMC-AP(if-wireless g)#

Related Commands key (page 6-86) key This command sets the keys used for WEP encryption. Use the no form to delete a configured key. Syntax key <index> <size> <type> <value>

no key index

index - Key index. (Range: 1-4)

size - Key size. (Options: 64, 128, or 152 bits)

type - Input format. (Options: ASCII, HEX)

value - The key string. For ASCII input, use 5/13 alphanumeric characters for 64/128 bit strings. For HEX input, use 10/26 hexadecimal digits for 64/128 bit strings. Default Setting None Command Mode Interface Configuration (Wireless) Command Usage

To enable Wired Equivalent Privacy (WEP), use the authentication command to select the shared key authentication type, use the encryption command to 6-86 Interface Commands specify the key length, and use the key command to configure at least one key.

If WEP is enabled, all wireless clients must be configured with the same shared keys to communicate with the access point.

The encryption length specified in the encryption command and the key command must match.

The encryption index, length and type configured in the access point must match those configured in the clients. Example SMC-AP(if-wireless g)#key 1 64 hex 1234512345 SMC-AP(if-wireless g)#key 2 128 ascii asdeipadjsipd SMC-AP(if-wireless g)#key 3 64 hex 12345123451234512345123456 SMC-AP(if-wireless g)#

Related Commands authentication (page 6-84) encryption (page 6-85) transmit-key This command sets the index of the key to be used for encrypting data frames broadcast or multicast from the access point to wireless clients. Syntax transmit-key <index>

index - Key index. (Range: 1-4) Default Setting 1 Command Mode Interface Configuration (Wireless) 6-87 Command Line Interface Command Usage

If you use WEP key encryption, the access point uses the transmit key to encrypt multicast and broadcast data signals that it sends to client devices. Other keys can be used for decryption of data from clients.

When using IEEE 802.1x, the access point uses a dynamic WEP key to encrypt unicast and broadcast messages to 802.1x-enabled clients. However, because the access point sends the WEP keys during the 802.1x authentication process, these keys do not have to appear in the clients WEP key list. Example SMC-AP(if-wireless g)#transmit-key 2 SMC-AP(if-wireless g)#

transmit-power This command adjusts the power of the radio signals transmitted from the access point. Syntax transmit-power <signal-strength>

signal-strength - Signal strength transmitted from the access point. (Options: full, half, quarter, eighth, min) Default Setting full Command Mode Interface Configuration (Wireless) Command Usage

The min keyword indicates minimum power.

The longer the transmission distance, the higher the transmission power required. But to support the maximum 6-88 Interface Commands number of users in an area, you must keep the power as low as possible. Power selection is not just a trade off between coverage area and maximum supported clients. You also have to ensure that high strength signals do not interfere with the operation of other radio devices in your area. Example SMC-AP(if-wireless g)#transmit-power half SMC-AP(if-wireless g)#

max-association This command configures the maximum number of clients that can be associated with the access point at the same time. Syntax max-association <count>

count - Maximum number of associated stations.

(Range: 0-64) Default Setting 64 Command Mode Interface Configuration (Wireless) Example SMC-AP(if-wireless g)#max-association 32 SMC-AP(if-wireless g)#

6-89 Command Line Interface multicast-cipher This command defines the cipher algorithm used for broadcasting and multicasting when using Wi-Fi Protected Access (WPA) security. Syntax multicast-cipher <AES | TKIP | WEP>

AES - Advanced Encryption Standard

TKIP - Temporal Key Integrity Protocol

WEP - Wired Equivalent Privacy Default Setting WEP Command Mode Interface Configuration (Wireless) Command Usage

WPA enables the access point to support different unicast encryption keys for each client. However, the global encryption key for multicast and broadcast traffic must be the same for all clients. This command sets the encryption type that is supported by all clients.

If any clients supported by the access point are not WPA enabled, the multicast-cipher algorithm must be set to WEP.

WEP is the first generation security protocol used to encrypt data crossing the wireless medium using a fairly short key. Communicating devices must use the same WEP key to encrypt and decrypt radio signals. WEP has many security flaws, and is not recommended for transmitting highly sensitive data.

TKIP provides data encryption enhancements including per-packet key hashing (i.e., changing the encryption key on each packet), a message integrity check, an extended initialization vector with sequencing rules, and a re-keying mechanism. 6-90 Interface Commands

TKIP defends against attacks on WEP in which the unencrypted initialization vector in encrypted packets is used to calculate the WEP key. TKIP changes the encryption key on each packet, and rotates not just the unicast keys, but the broadcast keys as well. TKIP is a replacement for WEP that removes the predictability that intruders relied on to determine the WEP key.

AES has been designated by the National Institute of Standards and Technology as the successor to the Data Encryption Standard (DES) encryption algorithm, and will be used by the U.S. government for encrypting all sensitive, nonclassified information. Because of its strength, and resistance to attack, AES is also being incorporated as part of the 802.11 standard. Example SMC-AP(if-wireless g)#multicast-cipher TKIP SMC-AP(if-wireless g)#

wpa-clients This command defines whether Wi-Fi Protected Access (WPA) is required or optionally supported for client stations. Syntax wpa-clients <required | supported>

required - Supports only clients using WPA.

supported - Support clients with or without WPA. Default Setting Supported Command Mode Interface Configuration (Wireless) 6-91 Command Line Interface Command Usage Wi-Fi Protected Access (WPA) provides improved data encryption, which was weak in WEP, and user authentication, which was largely missing in WEP. WPA uses the following security mechanisms. Enhanced Data Encryption through TKIP WPA uses Temporal Key Integrity Protocol (TKIP). TKIP provides data encryption enhancements including per-packet key hashing (i.e., changing the encryption key on each packet), a message integrity check, an extended initialization vector with sequencing rules, and a re-keying mechanism. Enterprise-level User Authentication via 802.1x and EAP To strengthen user authentication, WPA uses 802.1x and the Extensible Authentication Protocol (EAP). Used together, these protocols provide strong user authentication via a central RADIUS authentication server that authenticates each user on the network before they join it. WPA also employs mutual authentication to prevent a wireless client from accidentally joining a rogue network. Example SMC-AP(if-wireless g)#wpa-client required SMC-AP(if-wireless g)#

Related Commands wpa-mode (page 6-93) 6-92 Interface Commands wpa-mode This command specifies whether Wi-Fi Protected Access (WPA) is to use 802.1x dynamic keys or a pre-shared key. Syntax wpa-mode <dynamic | pre-shared-key>

dynamic - WPA with 802.1x dynamic keys.

pre-shared-key - WPA with a pre-shared key. Default Setting dynamic Command Mode Interface Configuration (Wireless) Command Usage

When the WPA mode is set to dynamic, clients are authenticated using 802.1x via a RADIUS server. Each client has to be WPA-enabled or support 802.1x client software. A RADIUS server must also be configured and be available in the wired network.

In the dynamic mode, keys are generated for each wireless client associating with the access point. These keys are regenerated periodically, and also each time the wireless client is re-authenticated.

When the WPA mode is set to pre-shared-key, the key must first be generated and distributed to all wireless clients before they can successfully associate with the access point. Example SMC-AP(if-wireless g)#wpa-mode pre-shared-key SMC-AP(if-wireless g)#

Related Commands wpa-clients (page 6-91) wpa-preshared-key (page 6-94) 6-93 Command Line Interface wpa-preshared-key This command defines a Wi-Fi Protected Access (WPA) preshared-key. Syntax wpa-preshared-key <type> <value>

type - Input format. (Options: ASCII, HEX)

value - The key string. For ASCII input, use 5/13 alphanumeric characters for 64/128 bit strings. For HEX input, use 10/26 hexadecimal digits for 64/128 bit strings. Command Mode Interface Configuration (Wireless) Command Usage

To support Wi-Fi Protected Access (WPA) for client authentication, use the wpa-clients command to specify the authentication type, use the wpa-mode command to specify pre-shared-key mode, and use this command to configure one static key.

If WPA is used with pre-shared-key mode, all wireless clients must be configured with the same pre-shared key to communicate with the access point. Example SMC-AP(if-wireless g)#wpa-preshared-key ASCII agoodsecret SMC-AP(if-wireless g)#

6-98 IAPP Commands IAPP Commands The command described in this section enables the protocol signaling required to ensure the successful handover of wireless clients roaming between different 802.11f-compliant access points. In other words, the 802.11f protocol can ensure successful roaming between access points in a multi-vendor environment. iapp This command enables the protocol signaling required to hand over wireless clients roaming between different 802.11f-compliant access points. Use the no form to disable 802.11f signaling. Syntax iapp no iapp Default Enabled Command Mode Global Configuration Command Usage The current 802.11 standard does not specify the signaling required between access points in order to support clients roaming from one access point to another. In particular, this can create a problem for clients roaming between access points from different vendors. This command is used to enable or disable 802.11f handover signaling between different access points, especially in a multi-vendor environment. Example SMC-AP(config)#iapp SMC-AP(config)#

6-99 Command Line Interface VLAN Commands The access point can enable the support of VLAN-tagged traffic passing between wireless clients and the wired network. Up to 16 VLAN IDs can be mapped to specific wireless clients, allowing users to remain within the same VLAN as they move around a campus site. When VLAN is enabled on the access point, a VLAN ID (a number between 1 and 4095) can be assigned to each client after successful authentication using IEEE 802.1x and a central RADIUS server. The user VLAN IDs must be configured on the RADIUS server for each user authorized to access the network. If a user does not have a configured VLAN ID, the access point assigns the user to its own configured native VLAN ID. Note: When VLANs are enabled, the access points Ethernet port drops all received traffic that does not include a VLAN tag. To maintain network connectivity to the access point and wireless clients, be sure that the access point is connected to a device port that supports IEEE 802.1Q VLAN tags. The VLAN commands supported by the access point are listed below. Command Function Mode Page vlan Enables a single VLAN for all traffic GC native-vlanid Configures the native VLAN for the access point GC 6-10 1 6-10 2 6-100 VLAN Commands vlan This command enables VLANs for all traffic. Use the no form to disable VLANs. Syntax vlan enable no vlan Default Disabled Command Mode Global Configuration Command Description

When VLANs are enabled, the access point tags frames received from wireless clients with the VLAN ID configured for each client on the RADIUS server. If the VLAN ID has not been configured for a client on the RADIUS server, then the frames are tagged with the access points native VLAN ID.

Traffic entering the Ethernet port must be tagged with a VLAN ID that matches the access points native VLAN ID, or with a VLAN tag that matches one of the wireless clients currently associated with the access point. Example SMC-AP(config)#vlan enable Reboot system now? <y/n>: y Related Commands native-vlanid (page 6-102) 6-101 Command Line Interface native-vlanid This command configures the native VLAN ID for the access point.

(Range: 1-16) Default Setting 1 Command Mode Global Configuration Command Usage When VLANs are enabled on the access point, a VLAN ID (a number between 1 and 4095) can be assigned to each client after successful authentication using IEEE 802.1x and a central RADIUS server. If a wireless client does not have a VLAN ID configured on the RADIUS server, the access point assigns the user to its own configured native VLAN ID (a number between 1 and 16). Example SMC-AP(config)#native-vlanid 3 SMC-AP(config)#

Related Commands vlan (page 6-101) 6-102 Appendix A Troubleshooting Check the following items before you contact local Technical Support. 1. If wireless clients cannot access the network, check the following:

Be sure the access point and the wireless clients are configured with the same Service Set ID (SSID). If authentication or encryption are enabled, ensure that the wireless clients are properly configured with the appropriate authentication or encryption keys. If authentication is being performed through a RADIUS server, ensure that the clients are properly configured on the RADIUS server. If authentication is being performed through IEEE 802.1x, be sure the wireless users have installed and properly configured 802.1x client software. If MAC address filtering is enabled, be sure the clients address is included in the local filtering database or on the RADIUS server database. If the wireless clients are roaming between access points, make sure that all the access points and wireless devices in the Extended Service Set (ESS) are configured to the same SSID, and authentication method. A-1 Troubleshooting 2. 3. If the access point cannot be configured using the Telnet, a web browser, or SNMP software:

Be sure to have configured the access point with a valid IP address, subnet mask and default gateway. If VLANs are enabled on the access point, the management station should be configured to send tagged frames with a VLAN ID that matches the access points native VLAN (default VLAN 1, page 5-19). However, to manage the access point from a wireless client, the AP Management Filter should be disabled (page 5-19). Check that you have a valid network connection to the access point and that the Ethernet port or the wireless interface that you are using has not been disabled. If you are connecting to the access point through the wired Ethernet interface, check the network cabling between the management station and the access point. If you are connecting to access point from a wireless client, ensure that you have a valid connection to the access point. If you cannot connect using Telnet, you may have exceeded the maximum number of concurrent Telnet sessions permitted (i.e, four sessions). Try connecting again at a later time.

If you cannot access the on-board configuration program via a serial port connection:

Be sure you have set the terminal emulator program to VT100 compatible, 8 data bits, 1 stop bit, no parity and 9600 bps. Check that the null-modem serial cable conforms to the pin-out connections provided in Appendix C.

A-2 4. 5. Troubleshooting If you forgot or lost the password:

Set the access point to its default configuration by pressing the reset button on the back panel for 5 seconds or more. Then use the default user name admin with the password smcadmin to access the management interface. If all other recovery measure fail, and the access point is still not functioning properly, take any of these steps:

Reset the access points hardware using the console interface, web interface, or through a power reset. Reset the access point to its default configuration by pressing the reset button on the back panel for 5 seconds or more. Then use the default user name admin with the password smcadmin to access the management interface.

Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards. For 10/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be red and the other, red with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable. Caution: Each wire pair must be attached to the RJ-45 connectors in a specific orientation. (See Straight-Through Wiring on page C-3 and Crossover Wiring on page C-3 for an explanation.) The following figure illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins. 8 8 1 1 C-1 Cables and Pinouts 10/100BASE-TX Pin Assignments Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet). The RJ-45 port on the access point is wired with MDI pinouts. This means that you must use crossover cables for connections to PCs or servers, and straight-through cable for connections to switches or hubs. However, when connecting to devices that support automatic MDI/MDI-X pinout configuration, you can use either straight-through or crossover cable.
