The LED for FAULT indicates the system failure and user-configured events. If the AWK-3121 cannot retrieve the IP address from a DHCP server, the FAULT LED will blink at an interval of one second. The LEDs for SIGNAL are a signal strength indicator and they merely function in Client mode. The following table is a summary for the wireless settings and LED displays. You can check the status of the AWK-3121 by reading these LEDs. More information about Basic Wireless Settings is presented in Chapter 3. Basic Wireless Settings Operation mode WDS CLIENT BRIDGE SIGNAL LEDs Note AP AP Client Client Client Disable Enable
off off on on on off on off off off
0 1 2-5 AP mode Bridge mode: WDS is enabled Client mode: no association Client mode: associated, but poor signal Client mode: associated; signal is fine 1-5 AirWorks AWK-3121 Users Manual Introduction ATTENTION When the LEDs for FAULT, SIGNAL, CLIENT, BRIDGE and WLAN all light up simultaneously and blink at one-second interval, it means the system failed to boot. This may be due to improper operation or uncontrollable issues, such as an unexpected shutdown during firmware update. To recover the firmware, refer to Firmware Recovery in Chapter 6. Beeper The beeper signals that the system is ready with two short beeps. Reset Button The RESET button is located on the top panel of the AWK-3121. You can reboot the AWK-3121 or reset it to factory default settings by pressing the RESET button with a pointed object such as an unfolded paper clip.
System reboot: Hold the RESET button down for under 5 seconds and then release.
Reset to factory default: Hold the RESET button down for over 5 seconds until the STATE LED starts blinking green. Release the button to reset the AWK-3121. Relay (Digital Output) The AWK-3121 has one relay output, which consists of the 2 terminal block contacts on the top panel, as shown below. These relay contacts are used to forward system failure and user-configured events. The two wires attached to the relay contacts form an open circuit when a user-configured event is triggered. If a user-configured event does not occur, the relay circuit will remain closed. For safety reason, the relay circuit is kept open when the AWK-3121 is not powered. The AWK-3121s relay status is summarized as follows:

First-time Installation and Configuration
Communication Testing
Function Guiding Map AirWorks AWK-3121 Users Manual Getting Started First-time Installation and Configuration Before installing the AWK-3121, make sure that all items in the Package Checklist are in the box. In addition, you will need access to a notebook computer or PC equipped with an Ethernet port. The AWK-3121 has a default IP address that you must use when connecting to the device for the first time. Step 1: Select the power source. The AWK-3121 can be powered by DC power input or PoE (Power over Ethernet). The AWK-3121 will use whichever power source you choose. Step 2: Connect the AWK-3121 to a notebook or PC. Since the AWK-3121 supports MDI/MDI-X auto-sensing, you can use either a straight-through cable or crossover cable to connect the AWK-3121 to a computer. If the LED indicator on AWK-3121s LAN port lights up, it means the connection is established. Step 3: Set up the computers IP address. Set an IP address on the same subnet as the AWK-3121. Since the AWK-3121s default IP address is 192.168.127.253, and the subnet mask is 255.255.255.0, you should set the IP address of the computer to 192.168.127.xxx. NOTE After you select Maintenance > Load Factory Default and click the Submit button, the AWK-3121 will be reset to factory default settings and the IP address will be also reset to 192.168.127.253.

Step 5: Select the operation mode for the AWK-3121. By default, the AWK-3121s operation mode is set to AP. You can change the setting in Wireless Settings > Basic Wireless Settings if you would like to use the Client mode instead. Detailed information about configuring the AWK-3121s operation can be found in Chapter 3. Step 6: Test communications. We will describe 2 test methods to make sure the network connection has been established. Please refer to the following section for more details. Communication Testing After installation, you can run a sample test to make sure the AWK-3121 and wireless connection are functioning normally. Two testing methods are explained in the following sections. Use the first method if you are using only one AWK-3121 device, and use the second method if you are using two or more AWK-3121s. Testing Method for one AWK-3121 If you are only using one AWK-3121, you will need a second notebook computer equipped with a WLAN card. Configure the WLAN card to connect to the AWK-3121 (NOTE: the default SSID is MOXA), and change the IP address of the second notebook (B) so that it is on the same subnet as the first notebook (A), which is connected to the AWK-3121. 2-3 AirWorks AWK-3121 Users Manual Getting Started After configuring the WLAN card, establish a wireless connection with the AWK-3121 and open a DOS window on Notebook B. At the prompt, type ping <IP address of notebook A>
and then press Enter (see the figure below). A Reply from IP address response means the communication was successful. A Request timed out. response means the communication failed. In this case, recheck the configuration to make sure the connections are correct. Testing Method for two or more AWK-3121s If you have two or more AWK-3121s, you will need a second notebook computer (B) equipped with an Ethernet port. Use the default settings for the first AWK-3121 connected to notebook A and change the second or third AWK-3121 connected to notebook B to Client mode. Then, configure the notebooks and AWK-3121s properly. After setting up the testing environment, open a DOS window on notebook B. At the prompt, type ping <IP address of notebook A>
and then press Enter. A Reply from IP address response means the communication was successful. A Request timed out response means the communication failed. In this case, recheck the configuration to make sure the connections are correct.

The AWK-3121 has a time calibration function based on information from an NTP server or user specified Date and Time information. Functions such as Auto warning can add real-time information to the message. 3-6 AirWorks AWK-3121 Users Manual Web Console Configuration You can click on the Modify button to initiate a time setting dialog box, as shown in the following figure. After setting the time and date parameters, you can click the Activate button to apply the setting or discard it by clicking Close. Local time settings will be immediately activated in the system without running Save and Restart. NOTE The AWK-3121 has a real time clock (RTC). Users are strongly recommended to update the Local time for the AWK-3121 after initial setup or long-term shutdown, especially when the network does not have an Internet connection for accessing the NTP server or there is no NTP server on the LAN. Local time Setting User adjustable time Time zone Setting User selectable time zone Description The date and time parameters allow configuration of the local time with an interactive dialog box. Factory Default None

Description This parameter determines how frequently the time is updated from the NTP server. Factory Default None Factory Default 600 (seconds) Wireless Settings The essential settings for wireless networks are presented in this function group. Settings must be properly set before establishing your wireless network. Basic Wireless Settings The AWK-3121 mainly supports two operational modes that have distinct roles in the wireless network:
AP/Bridge:
This mode provides both Access Point and Static LAN-to-LAN Bridging functionality. The static LAN-to-LAN bridging function is supported through the Wireless Distribution System
(WDS).
AP Client:
This mode is for Dynamic LAN-to-LAN Bridging or Device-to-LAN. The AP Client automatically establishes bridge links with other APs. In either mode, the AWK-3121 forwards packets between its Ethernet interface (LAN) and wireless interface (WLAN) for wired hosts on the Ethernet side and wireless host(s) on the wireless side. There are two types of wireless links as specified by the IEEE802.11 standard:
STA-AP This type of wireless link is established between an IEEE802.11 Station (STA) and an IEEE802.11 Access Point (AP). An STA is usually a client computer (PC or PDA) with a WLAN network interface card (NIC). The Client mode is actually an STA.
WDS This type of wireless link is established between two IEEE802.11 APs. Wireless packets transmitted along the WDS link comply with the IEEE802.11 WDS (Wireless Distribution System) format at the link layer. You can refer to Wireless Distribution System (WDS) in Chapter 5 for more details. Be reminded that WPA/WPA2 CANNOT be supported in WDS. 3-8 AirWorks AWK-3121 Users Manual Web Console Configuration To establish a static bridge link based on the WDS, the APs at both end of the WDS link must be configured manually with each other's MAC addresses. To establish a dynamic bridge link between an AP and a Client, both devices must be configured with the same, channel, and security settings (see WLAN Security Settings). Moreover, the same SSID is also needed if a client will roam along the APs in Bridge mode. The AP Client automatically scans for any AP that is using the matched SSID and establishes a bridge link with the scanned AP. When the AWK-3121 is configured to be in Client mode, it can be used as an Ethernet-to-wireless
(or LAN-to-WLAN) network adapter. For example, a notebook computer equipped with an Ethernet adapter, but no wireless card, can be connected to this device with an Ethernet cable for wireless connectivity to another AP. NOTE Although it is more convenient to use dynamic bridging, there is a limitation the AP Client can only transmit IP-based packets between its wireless interface (WLAN) and Ethernet interface
(LAN); other types of traffic (such as IPX and AppleTalk) are not forwarded. The following figure shows the Basic Wireless Settings page. The parameters and options are described as follow:
Operation mode Setting AP Client Description AWK-3121 plays a role of wireless AP/ Bridge. AWK-3121 plays a role of wireless AP Client. Factory Default AP NOTE When you switch to Client mode, you can find an additional Site Survey button on this page. It can support site survey and pop up a dialog box listing the information of available APs, as shown in the following figure. You can click on the SSID of an entity and bring the value of its SSID onto the SSID field of the Basic Wireless Settings page. Clicking on the Refresh button will re-scan and update the table. 3-9 AirWorks AWK-3121 Users Manual Web Console Configuration NOTE If the Gateway field in Basic Settings > Network Settings is empty, a warning message will appear, reminding you to set the default gateway when Client mode is enabled. You can ignore this message if you are only planning a local network and no packet will be sent outside the network. RF type Setting A B G B/G Mixed Factory Default B/G Mixed Description Supports IEEE802.11a standard only Supports IEEE802.11b standard only Supports IEEE802.11g standard only Supports both of IEEE802.11b/g standards, but 802.11g can be slowed down when 802.11b clients are on the network Channel (for AP mode only) Setting Available channels vary with RF type Description AWK-3121 plays a role of wireless AP.

Factory Default MOXA SSID broadcast (for AP mode only) Setting Enable/ Disable Description SSID can be broadcast or not. Factory Default Enable NOTE AWK-3121-JP (JP-band version) can merely support disabling SSID broadcast in all channels of IEEE802.11a and channel 1 to 11 of IEEE802.11g. WDS (for AP mode only) Setting Enable/ Disable Description AWK-3121 supports WDS or not. Factory Default Disable NOTE The AWK-3121 provides 8 entities for WDS settings and can support up to 8 WDS links to other APs or wireless bridges. The list appears when WDS Enable is checked. Enter the MAC address to set up a WDS link. Remember to activate a WDS link by checking the Active check box. 3-11 AirWorks AWK-3121 Users Manual Web Console Configuration WLAN Security Settings The AWK-3121 provides four standardized wireless security modes: Open, WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected Access) and WPA2. Several types of security models are available in AWK-3121 by selecting Security mode and WPA type:
Open: No authentication, no data encryption.
WEP: Static WEP (Wired Equivalent Privacy) keys must be manually configured.
WPA/WPA2-Personal: also known as WPA/WPA2-PSK. You need to specify the Pre-Shared Key in the Passphrase field, which will be used by the TKIP or AES engine as a master key to generate keys that actually encrypt outgoing packets and decrypt incoming packets.
WPA/WPA2-Enterprise: also called WPA/WPA2-EAP (Extensible Authentication Protocol). In addition to device-based authentication, WPA/WPA2-Enterprise enables user-based authentication via IEEE802.1X. The AWK-3121 can support three EAP methods: EAP-TLS, EAP-TTLS, and EAP-PEAP. Factory Default Open Security mode Setting Open WEP WPA*
WPA2*
Open Description No authentication Static WEP is used WPA is used Fully supports IEEE802.11i with TKIP/AES + 802.1X
* WPA and WPA2 cannot be supported in WDS (Bridge) mode. For security reasons, it is highly recommended that the security mode should be set to the options other than Open System. When the security mode is set to Open System, no authentication or data encryption will be performed. WEP According to the IEEE802.11 standard, WEP can be used for authentication and data encryption
(confidentiality). Shared (or Shared Key) authentication type is used if WEP authentication and data encryption are both needed. Normally, Open (or Open System) authentication type is often used when WEP data encryption is run with authentication. When WEP is enabled as a security mode, the length of a key (so-called WEP seed) can be specified as 64/128 bits, which is actually a 40/104-bit secret key with a 24-bit initialization vector. The AWK-3121 provides 4 entities of WEP key settings that can be selected to use with Key index. The selected key setting specifies the key to be used as a send-key for encrypting traffic from the AP side to the wireless client side. All 4 WEP keys are used as receive-keys to decrypt traffic from the wireless client side to the AP side. 3-12 AirWorks AWK-3121 Users Manual Web Console Configuration The WEP key can be presented in two Key type, HEX and ASCII. Each ASCII character has 8 bits, so a 40-bit (or 64-bit) WEP key contains 5 characters, and a 104-bit (or 128-bit) key has 13 characters. In hex, each character uses 4 bits, so a 40-bit key has 10 hex characters, and a 128-bit key has 26 characters. Description Data encryption is enabled, but no authentication Data encryption and authentication are both enabled. Factory Default Open Description Specifies WEP keys in hex-decimal number form Specifies WEP keys in ASCII form Factory Default HEX Description Uses 40-bit secret keys with 24-bit initialization vector Uses 104-bit secret key with 24-bit initialization vector Factory Default 64 bits Description Specifies which WEP key is used Factory Default Open Description A string that can be used as a WEP seed for RC4 encryption engine.

WPA is a security standard based on 802.11i draft 3, while WPA2 is based on the fully ratified version of 802.11i. The initial vector is transmitted, encrypted, and enhanced with its 48 bits, twice as long as WEP. The key is regularly changed so that true session is secured. Even though AES encryption is only included in the WPA2 standard, it is widely available in the WPA security mode of some wireless APs and clients as well. The AWK-3121 also supports AES algorithms in WPA and WPA2 for better compatibility. Personal versions of WPA/WPA2, also know as WPA/WPA-PSK (Pre-Shared Key), provides a simple way of encrypting a wireless connection for high confidentiality. A Passphrase is used as a basis for encryption methods (or cipher types) in a WLAN connection. The passphrases should be complex and as long as possible. The number of ASCII characters of the Passphrase must be at least 8 and can go up to 63. For security reason, this passphrase should be disclosed to the relevant users only and changed regularly.

Usually the security level will be higher if you set this value shorter so that the encryption keys are changed more often. Default value is 3600 seconds (6 minutes). Longer time periods can be considered if traffic is not so busy. WPA/WPA2-Enterprise (for AP mode) By selecting WPA type as Enterprise, you can use EAP (Extensible Authentication Protocol), a framework authentication protocol used by 802.1X to provide network authentication. In these Enterprise-level security modes, a back-end RADIUS (Remote Authentication Dial-In User Service) server is needed if IEEE 802.1X functionality is enabled in WPA /WPA2. The IEEE 802.1X protocol also offers the possibility of carrying out an efficient connection authentication in a large-scaled network. It is not necessary to exchange keys or passphrases.

Encryption method Setting TKIP AES EAP Protocol Setting TLS TTLS PEAP Description Temporal Key Integrity Protocol is enabled Advance Encryption System is enabled Description Specifies Transport Layer Security protocol Specifies Tunneled Transport Layer Security Specifies Protected Extensible Authentication Protocol, or Protected EAP Factory Default TKIP Factory Default TLS 3-16 AirWorks AWK-3121 Users Manual Web Console Configuration Before choosing the EAP protocol for your WPA/WPA2-Enterpise settings on the client end, please contact the network administrator to make sure the system supports the protocol on the AP end. Detailed information on these three popular EAP protocols is presented in the following sections:
EAP-TLS TLS is the standards-based successor to the Secure Socket Layer (SSL). It can establish a trusted communication channel over a distrusted network. TLS provides mutual authentication through certificate exchange. EAP-TLS is also secure to use. You are required to submit a digital certificate to the authentication server for validation, but the authentication server must also supply a certificate. You can use Basic Wireless Settings > WLAN Certificate Settings to import your WLAN certificate and enable EAP-TLS on the client end. You can check the current certificate status in Current Certificate if it is available. Certificate issued to: shows the certificate user Certificate issued by: shows the certificate issuer Certificate expiration date: indicates when the certificate gets invalid EAP-TTLS It is usually much easier to re-use existing authentication systems, such as a Windows domain or Active Directory, LDAP directory, or Kerberos realm, rather than creating a parallel authentication system. As a result, TTLS (Tunneled TLS) and PEAP (Protected EAP) are used to support the use of so-called legacy authentication methods. TTLS and PEAP work in a similar way. First, they establish a TLS tunnel, like EAP-TLS, and validate whether the network is trustworthy with digital certificates on the authentication server. This step is run to establish a tunnel that protects the next step (or inner authentication) so it is sometimes referred to as the outer authentication. Then the TLS tunnel is used to encrypt an older authentication protocol that authenticates the user for the network. As you can see, digital certificates are still needed for the outer authentication in a simplified form. Only a small number of certificates are required, which can be generated by a small certificate authority. Certificate reduction makes TTLS and PEAP much more popular than EAP-TLS. The AWK-3121 provides some non-cryptographic EAP methods including PAP, CHAP, MS-CHAP, and MS-CHAP-V2. These EAP methods are not recommended for direct use on wireless networks. However, they may be useful as inner authentication methods with TTLS or PEAP. 3-17 AirWorks AWK-3121 Users Manual Web Console Configuration Because the inner and outer authentications can use distinct user names in TTLS and PEAP, you can use an anonymous user name for the outer authentication, while the true user name is shown only through the encrypted channel. Remember, not all client software supports anonymous altercation. Confirm this with the network administrator before you enable identity hiding in TTLS and PEAP. Factory Default MS-CHAP-V2 Description Password Authentication Protocol is used Challenge Handshake Authentication Protocol is used Microsoft CHAP is used Microsoft CHAP version 2 is used Description A distinct name used for outer authentication Factory Default None TTL Inner Authentication Setting PAP CHAP MS-CHAP MS-CHAP-V2 Anonymous Setting Max. 31 characters User name & Password Setting Description User name and password used in inner authentication Factory Default None PEAP There are a few differences in the inner authentication procedures for TTLS and PEAP. TTLS uses the encrypted channel to exchange attribute-value pairs (AVPs), while PEAP uses the encrypted channel to start a second EAP exchange inside of the tunnel. The AWK-3121 provides MS-CHAP-V2 merely as an EAP method for inner authentication. 3-18 AirWorks AWK-3121 Users Manual Web Console Configuration Inner EAP protocol Setting MS-CHAP-V2 Anonymous Setting Max. 31 characters User name & Password Description Factory Default Microsoft CHAP version 2 is used MS-CHAP-V2 Description A distinct name used for outer authentication Factory Default None Setting Description User name and password used in inner authentication Factory Default None Advanced Wireless Settings Additional wireless-related parameters are presented in this section to help you set up your wireless network in detail.

By setting these parameters properly, you can better tune the performance of your wireless network. 3-20 AirWorks AWK-3121 Users Manual Web Console Configuration WLAN Certification Settings (for EAP-TLS in Client mode only) When EAP-TLS is used, a WLAN Certificate will be required at the client end to support WPA/WPA2-Enterprise. The AWK-3121 can support the PKCS #12, also known as Personal Information Exchange Syntax Standard, certificate formats that define file formats commonly used to store private keys with accompanying public key certificates, protected with a password-based symmetric key. Current Certificate displays information for the current WLAN certificate, which has been imported into the AWK-3121. Nothing will be shown if no certificate is available. Certificate issued to: shows the certificate user Certificate issued by: shows the certificate issuer Certificate expiration date: indicates when the certificate gets invalid You can import a new WLAN certificate in Import WLAN Certificate by following these steps in order:
1. Input the corresponding password (or key) in the Certificate private password field. Then click Submit to set the password. 2. You can see the password displayed in the Certificate private password field. Then click on the Browse button in Select certificate/key file and select the certificate file. 3. Click Upload Certificate File to import the certificate file. If it succeeds, you can see the information uploaded in Current Certificate. If it fails, you may need to return to step 1 to set the password correctly and then import the certificate file again. NOTE The WLAN certificate will remain after the AWK-3121 reboots. Even though it is expired, it can still be seen on Current Certificate. 3-21 AirWorks AWK-3121 Users Manual Web Console Configuration Advanced Settings Several advanced functions are available to increase the functionality of your AWK-3121 and wireless network system. The DHCP server helps you deploy wireless clients efficiently. Packet filters provide security mechanisms, such as firewalls, in different network layers. Moreover, the AWK-3121 can support STP/RSTP protocol to increase the reliability across the entire network. In additional, SNMP support can ease the network management via SNMP protocols. DHCP Server (for AP mode only) DHCP (Dynamic Host Configuration Protocol) is a networking protocol that allows administrators to assign temporary IP addresses to network computers by leasing an IP address to a user for a limited amount of time, instead of assigning permanent IP addresses. The AWK-3121 can act as a simplified DHCP server and easily assign IP addresses to your wireless clients by responding to the DHCP requests from the client ends. The IP-related parameters you set on this page will also be sent to the client. You can also assign a static IP address to a specific client by entering its MAC address. The AWK-3121 provides a Static DHCP mapping list with up to 16 entities. Be reminded to check the Active check box for each entity to activate the setting. You can check the IP assignment status under Status > DHCP Client List.

Factory Default None Factory Default Factory Default None None Factory Default 10 (days) The AWK-3121 includes various filters for IP-based packets going through LAN and WLAN interfaces. You can set these filters as a firewall to help enhance network security. MAC Filter The AWK-3121s MAC filter is a policy-based filter that can allow or filter out IP-based packets with specified MAC addresses. The AWK-3121 provides 8 entities for setting MAC addresses in your filtering policy. Remember to check the Active check box for each entity to activate the setting. 3-23 AirWorks AWK-3121 Users Manual Web Console Configuration Setting Setting Enable Enable Disable Policy Accept Drop Description Enables MAC filter Disables MAC filter Description Only the packets fitting the entities on list can be allowed. Any packet fitting the entities on list will be denied. Factory Default Disable Factory Default Drop ATTENTION Be careful when you enable the filter function:
Drop + no entity on list is activated = all packets are allowed Accept + no entity on list is activated = all packets are denied IP Protocol Filter The AWK-3121s IP protocol filter is a policy-based filter that can allow or filter out IP-based packets with specified IP protocol and source/destination IP addresses. The AWK-3121 provides 8 entities for setting IP protocol and source/destination IP addresses in your filtering policy. Four IP protocols are available: All, ICMP, TCP, and UDP. You must specify either the Source IP or the Destination IP. By combining IP addresses and netmasks, you can specify a single IP address or a range of IP addresses to accept or drop. For example, IP address 192.168.1.1 and netmask 255.255.255.255 refers to the sole IP address 192.168.1.1. IP address 192.168.1.1 and netmask 255.255.255.0 refers to the range of IP addresses from 192.168.1.1 to 192.168.255. Remember to check the Active check box for each entity to activate the setting. 3-24 AirWorks AWK-3121 Users Manual Web Console Configuration Setting Setting Enable Enable Disable Policy Accept Drop Description Enables IP protocol filter Disables IP protocol filter Description Only the packets fitting the entities on the list can be allowed Any packet fitting the entities on the list will be denied Factory Default Disable Factory Default Drop ATTENTION Be careful when you enable the filter function:
Drop + no entity on list is activated = all packets are allowed. Accept + no entity on list is activated = all packets are denied. TCP/UDP Port Filter The AWK-3121s TCP/UDP port filter is a policy-based filter that can allow or filter out TCP/UDP-based packets with a specified source or destination port. The AWK-3121 provides 8 entities for setting the range of source/destination ports of a specific protocol. In addition to selecting TCP or UDP protocol, you can set either the source port, destination port, or both. The end port can be left empty if only a single port is specified. Of course, the end port cannot be larger then the start port. The Application name is a text string that describes the corresponding entity with up to 31 characters. Remember to check the Active check box for each entity to activate the setting. 3-25 AirWorks AWK-3121 Users Manual Web Console Configuration Setting Setting Enable Enable Disable Policy Accept Drop Description Enables TCP/UDP port filter Disables TCP/UDP port filter Factory Default Disable Description Only the packets fitting the entities on list can be allowed. Any packet fitting the entities on list will be denied. Factory Default Drop ATTENTION Be careful when you enable the filter function:
Drop + no entity on list is activated = all packets are allowed Accept + no entity on list is activated = all packets are denied RSTP Settings (for AP mode only) AWK-3121 supports IEEE802.1D Spanning Tree Protocol and IEEE802.1w Rapid STP standards. In addition to eliminating unexpected path looping, STP/RSTP can provide a backup path recovery if a wired/ wireless path fails accidentally. The reliability and availability can increase because this fail-over function. AWK-3121s STP/RSTP feature is disabled by default. To be completely effective, you must enable RSTP/STP on every AWK-3121 connected to your network. If AWK-3121 plays a Client role, which is connected to a device (PLC, RTU, etc.) as opposed to network switch equipment, it is not necessary to enable STP/RSTP. The reason is that it will cause unnecessary negotiation. AWK-3121s support STP/RSTP in AP mode (including WDS) only. The following figures indicate which Spanning Tree Protocol parameters can be configured. A more detailed explanation of each parameter is given below the figure. 3-26 AirWorks AWK-3121 Users Manual Web Console Configuration RSTP status This field will appear only when selected to operate STP/RSTP. It indicates whether this AWK-3121 is the Root of the Spanning Tree (the root is determined automatically) or not. Bridge priority Setting Numerical value selected by user Hello time Setting Numerical value input by user
(1 10 seconds) Forwarding delay Setting Numerical value input by user
(4 30 seconds) Max. age Setting Numerical value input by user
(6 40 seconds) Factory Default 32768 Factory Default 2 (seconds) Description You can increase the bridge priority by selecting a lower number. A higher bridge priority brings a greater chance of being established as the root of the Spanning Tree topology. Description The root of the Spanning Tree topology periodically sends out a hello message to other devices on the network to check if the topology is healthy. Hello time indicates how often the root sends hello messages. Description The amount of time this device waits before checking to see if it should change to a different topology. Factory Default 15 (seconds) Factory Default 20 (seconds) Description As a non-root role, if the device has not received a hello message from the root longer than Max. age, it will reconfigure itself as a root. Once two or more devices on the network are recognized as a root, the devices will renegotiate to set up a new Spanning Tree topology. 3-27 AirWorks AWK-3121 Users Manual Web Console Configuration The AWK-3121 comes with 10 ports for RSTP settings. Numbers 3-10 (WDS1-WDS8) are available only when WDS is enabled in AP mode. Enable RSTP Setting Enable/ disable Port priority Setting Numerical value selected by user Port cost Setting Enable/ Disable Edge port Setting Checked/ unchecked Description Enables or disables the port as a node on the Spanning Tree topology. Factory Default Disable (unchecked) Description Increase this ports priority as a node on the Spanning Tree topology by inputting a lower number. 128 Factory Default Description Input a higher cost to indicate that this port is less suitable as a node for the Spanning Tree topology Factory Default 2000000 Description Sets a port, which no BPDU expectedly goes through, as an edge port Factory Default unchecked, except AP port NOTE We recommend you set an edge port for the port, which is connected to a non-STP/RSTP sub-network or an end device (PLC, RTU, etc.) as opposed to network equipment. This can prevent unnecessary waiting and negotiation of STP/RSTP protocol, and accelerate system initialization. When an edge port receives BPDUs, it can still function as an STP/RSTP port and start negotiation. Setting an edge port is different from disabling STP/RSTP on a port. If you disable STP/RSTP, a port will not deal with STP/RSTP BPDUs at all. Port Status Port Status indicates the current Spanning Tree status of this port. Use Forwarding for normal transmission, or Blocking to block transmission. SNMP Agent The AWK-3121 supports SNMP V1/V2c/V3. SNMP V1 and SNMP V2c use a community string match for authentication, which means that SNMP servers access all objects with read-only or read/write permissions using the community string public/private (default value). SNMP V3, which requires you to select an authentication level of MD5 or SHA, is the most secure protocol. You can also enable data encryption to enhance data security. The AWK-3121s MIB can be found in the software CD and supports reading the attributes via SNMP. (Only get method is supported.) 3-28 AirWorks AWK-3121 Users Manual Web Console Configuration SNMP security modes and security levels supported by the AWK-3121 are shown in the following table. Select the security mode and level that will be used to communicate between the SNMP agent and manager.

This is the AWK-3121s enterprise value. It is fixed. Auto Warning Settings Since industrial-grade devices are often located at the endpoints of a system, these devices will not always know what is happening elsewhere on the network. This means that these devices, including wireless APs or clients, must provide system maintainers with real-time alarm messages. Even when system administrators are out of the control room for an extended period, they can still be informed of the status of devices almost instantaneously when exceptions occur. In addition to logging these events, the AWK-3121 supports different approaches to warn engineers automatically, such as SNMP trap, e-mail, and relay output. It also supports two digital inputs to integrate sensors into your system to automate alarms by email and relay output. 3-30 AirWorks AWK-3121 Users Manual Web Console Configuration System Log System Log Event Types Detail information for grouped events is shown in the following table.

These relay contacts are used to indicate user-configured events and system failure. The two wires attached to the relay contacts form an open circuit when a user-configured event is triggered. If a user-configured event does not occur, the relay circuit will remain closed. For safety reasons, the relay circuit is kept open when the AWK-3121 is not powered. Relay Event Types You can check the box for Active to enable the event items. All default values are deactivated
(unchecked). Details for each event item can be found in the System log Event Types table on page 3-31. 3-34 AirWorks AWK-3121 Users Manual Web Console Configuration Trap Traps can be used to signal abnormal conditions (notifications) to a management station. This trap-driven notification can make your network more efficient. Because a management station usually takes care of a large number of devices that have a large number of objects, it will be overloading for the management station to poll or send requests to query every object on every device. It would be better if the managed device agent could notify the management station by sending a message known as a trap for the event. Trap Event Types SNMP Trap Receiver Settings SNMP traps are defined in SMIv1 MIBs (SNMPv1) and SMIv2 MIBs (SNMPv2c). The two styles are basically equivalent, and it is possible to convert between the two. You can set the parameters for SNMP trap receivers through the web page. 1st / 2nd Trap version Setting Description SNMP trap defined in SNMPv1 SNMP trap defined in SNMPv2 V1 V2 V1 Factory Default 3-35 AirWorks AWK-3121 Users Manual Web Console Configuration 1st / 2nd Trap server IP/name Setting Description IP address or host name Enter the IP address or name of the trap server used by your network. 1st / 2nd Trap community Setting Max. 31 characters Description Use a community string match with a maximum of 31 characters for authentication.

The status will refresh every 5 seconds if the Auto refresh box is checked. Certain values for 802.11 info may not show up due to different operation modes. As a result, Current BSSID and RSSI are not available in AP mode. It is helpful to use the continuously updated information on this page, such as RSSI, to monitor the signal strength of the AWK-3121 in Client mode. Maintenance Maintenance functions provide the administrator with tools to manage the AWK-3121 and wired/wireless networks. Console Settings You can enable or disable access permission for the following consoles: HTTP, HTTPS, Telnet and SSH connections. For more security, we recommend you only allow access to the two secured consoles, HTTPS and SSH. 3-38 AirWorks AWK-3121 Users Manual Web Console Configuration Ping Ping helps to diagnose the integrity of wired or wireless networks. By inputting a nodes IP address in the Destination field, you can use the ping command to make sure it exists and whether or not the access path is available. If the node and access path are available, you will see that all packets were successfully transmitted with no loss. Otherwise, some, or even all, packets may get lost, as shown in the following figure. Firmware Upgrade The AWK-3121 can be enhanced with more value-added functions by installing firmware upgrades. The latest firmware is available at Moxas download center. Before running a firmware upgrade, make sure the AWK-3121 is off-line. Click the Browse button to specify the firmware image file and click Firmware Upgrade and Restart to start the firmware upgrade. After the progress bar reaches 100%, the AWK-3121 will reboot itself. When upgrading your firmware, the AWK-3121s other functions are forbidden. 3-39 AirWorks AWK-3121 Users Manual Web Console Configuration ATTENTION Please make sure the power source is stable when you upgrade your firmware. An unexpected power breakup may damage your AWK-3121. Config Import Export You can back up or restore the AWK-3121s configuration with Config Import Export. In the Config Import section, click Browse to specify the configuration file and click Config Import button to begin importing the configuration. In the Config Export section, click the Config Export button and save the configuration file onto your local storage media. The configuration file is a text file and you can view and edit it with a general text-editing tool. Load Factory Default Use this function to reset the AWK-3121 and roll all settings back to the factory default values. You can also reset the hardware by pressing the reset button on the top panel of the AWK-3121. 3-40 AirWorks AWK-3121 Users Manual Web Console Configuration Password You can change the administration password for each of the AWK-3121s console managers by using the Password function. Before you set up a new password, you must input the current password and reenter the new password for confirmation. For your security, do not use the default password root, and remember to change the administration password regularly. Save Configuration The following figure shows how the AWK-3121 stores the setting changes into volatile and non-volatile memory. All data stored in volatile memory will disappear when the AWK-3121 is shutdown or rebooted unless they are y. Because the AWK-3121 starts up and initializes with the settings stored in flash memory, all new changes must be saved to flash memory before restarting the AWK-3121. This also means the new changes will not work unless you run either the Save Configuration function or the Restart function. After you click on Save Configuration in the left menu box, the following screen will appear. Click Save if you wish to update the configuration settings in the flash memory at this time. Alternatively, you may choose to run other functions and put off saving the configuration until later. However, the new setting changes will remain in the non-volatile memory until you save the configurations. 3-41 AirWorks AWK-3121 Users Manual Web Console Configuration Restart If you submitted configuration changes, you will find a blinking string in the upper right corner of the screen. After making all your changes, click the Restart function in the left menu box. One of two different screens will appear. If you made changes recently but did not save, you will be given two options. Clicking the Restart button here will reboot the AWK-3121 directly, and all setting changes will be ignored. Clicking the Save and Restart button will apply all setting changes and then reboot the AWK-3121. If you run the Restart function without changing any configurations, you will see just one Restart button on your screen. You will not be able to run any of the AWK-3121s functions while the system is rebooting. 3-42 AirWorks AWK-3121 Users Manual Web Console Configuration Logout Logout helps users disconnect the current HTTP or HTTPS session and go to the Login page. For security reasons, we recommend you logout before quitting the console manager. 3-43 44 Chapter 4 Other Console Configurations This chapter explains how to access the AWK-3121 for the first time. In addition to HTTP access, there are four ways to access AWK-3121: serial console, Telnet console, SSH console, and HTTPS console. The serial console connection method, which requires using a short serial cable to connect the AWK-3121 to a PCs COM port, can be used if you do not know the AWK-3121s IP address. The other consoles can be used to access the AWK-3121 over an Ethernet LAN, or over the Internet. In this chapter, we cover the following topics:
RS-232 Console Configuration (115200, None, 8, 1, VT100)
Configuration by Telnet and SSH Consoles
Configuration by Web Browser with HTTPS/SSL
Disabling Telnet and Browser Access AirWorks AWK-3121 Users Manual Other Console Configurations ATTENTION simultaneously. 1. You CANNOT connect to the AWK-3121 by two ore more of these console configurations 2. You can connect to the AWK-3121 simultaneously by web browser and serial/ Telnet /SSH console. However, we strongly suggest that you do NOT use more than one connection method at the same time. Following this advice will allow you to maintain better control over the configuration of your AWK-3121. RS-232 Console Configuration (115200, None, 8, 1, VT100) The serial console connection method, which requires using a short serial cable to connect the AWK-3121 to a PCs COM port, can be used if you do not know the AWK-3121s IP address. It is also convenient to use serial console configurations when you cannot access the AWK-3121 over Ethernet LAN, such as in the case of LAN cable disconnections or broadcast storming over the LAN. ATTENTION Do not use the RS-232 console manager when the AWK-3121 is powered at reversed voltage
(ex. -48VDC), even though reverse voltage protection is supported. NOTE We recommend using Moxa PComm (Lite) Terminal Emulator, which can be downloaded free of charge from Moxas website. Before running PComm Terminal Emulator, use an RJ45 to DB9-F (or RJ45 to DB25-F) cable to connect the AWK-3121s RS-232 console port to your PCs COM port (generally COM1 or COM2, depending on how your system is set up). After installing PComm Terminal Emulator, take the following steps to access the RS-232 console utility. 1. From the Windows desktop, open the Start menu and start PComm Terminal Emulator in the PComm (Lite) group. 4-2 AirWorks AWK-3121 Users Manual Other Console Configurations 2. Select Open under Port Manager to open a new connection. 3. The Communication Parameter page of the Property window opens. Select the appropriate COM port for Console Connection, 115200 for Baud Rate, 8 for Data Bits, None for Parity, and 1 for Stop Bits. 4. Click on the Terminal tab, and select VT100 (or ANSI) for Terminal Type. Click on OK to continue. 5. The Console login screen will appear. Log into the RS-232 console with the login name
(default: admin) and password (default: root, if no new password is set). 4-3 AirWorks AWK-3121 Users Manual Other Console Configurations 6. The AWK-3121s device information and Main Menu will be displayed. Please follow the description on screen and select the administration option you wish to perform. NOTE To modify the appearance of the PComm Terminal Emulator window, select Edit > Font and then choose the desired formatting options. ATTENTION If you unplug the RS-232 cable or trigger DTR, a disconnection event will be evoked to enforce logout for network security. You will need to log in again to resume operation. Configuration by Telnet and SSH Consoles You may use Telnet or SSH client to access the AWK-3121 and manage the console over a network. To access the AWK-3121s functions over the network from a PC host that is connected to the same LAN as the AWK-3121, you need to make sure that the PC host and the AWK-3121 are on the same logical subnet. To do this, check your PC hosts IP address and subnet mask. NOTE The AWK-3121s default IP address is 192.168.127.253 and the default subnet mask is 255.255.255.0 (for a Class C network). If you do not set these values properly, please check the network settings of your PC host and then change the IP address to 192.168.127.xxx and subnet mask to 255.255.255.0. 4-4 AirWorks AWK-3121 Users Manual Other Console Configurations Follow the steps below to access the console utility via Telnet or SSH client. 1. From Windows Desktop, run Start > Run, and then use Telnet to access the AWK-3121s IP address from the Windows Run window. (You may also issue the telnet command from the MS-DOS prompt.) When using SSH client (ex. PuTTY), please run the client program (ex. putty.exe) and then input the AWK-3121s IP address, specifying 22 for the SSH connection port. 2. The Console login screen will appear. Please refer to the previous paragraph RS-232 Console Configuration and for login and administration. Configuration by Web Browser with HTTPS/SSL To secure your HTTP access, the AWK-3121 supports HTTPS/SSL encryption for all HTTP traffic. Perform the following steps to access the AWK-3121s web browser interface via HTTPS/SSL. 1. Open your web browser and type https://<AWK-3121s IP address> in the address field. Press Enter to establish the connection. 2. Warning messages will pop out to warn users that the security certificate was issued by a company they have not chosen to trust. 4-5 AirWorks AWK-3121 Users Manual Other Console Configurations 3. Select Yes to accept the certificate issued by Moxa IW and then enter the AWK-3121s web browser interface secured via HTTPS/SSL. (You can see the protocol in URL is https.) Then you can use the menu tree on the left side of the window to open the function pages to access each of AWK-3121s functions. Disabling Telnet and Browser Access If you are connecting the AWK-3121 to a public network but do not intend to use its management functions over the network, then we suggest disabling both Telnet Console and Web Configuration. Please run Maintenance > Console Settings to disable them, as shown in the following figure. 4-6 55 Chapter 5 References This chapter provides more detailed information about wireless-related technologies. The information in this chapter can help you administer your AWK-3121s and plan your industrial wireless network better. The following topics are covered:
Wireless Distribution System (WDS)
Beacon
DTIM
Fragment
RTS Threshold
STP and RSTP
The STP/RSTP Concept
Differences between RSTP and STP AirWorks AWK-3121 Users Manual References Wireless Distribution System (WDS) Traditionally, APs are connected via Ethernet LAN ports. By using a Wireless Distribution System
(WDS), APs can communicate with one another wirelessly. For example, AP 2 acts as an access point for the notebook computers or other IEEE802.11-enabled clients, and forwards packets sent from the notebook computers to AP 1 through WDS. Then, AP 1 forwards the packets to the Ethernet LAN. Packets destined for the notebook computers follow a reverse path from the Ethernet LAN through the APs to the notebook computers. In this way, AP 2 acts as an AP repeater. By using WDS, two or more LAN segments can be connected wirelessly. As illustrated in the above figure, a pair of wireless LAN-to-LAN bridges is used to connect two LAN segments. Since the AP is WDS-enabled, it can be used as a wireless bridge. It is a good idea to plan your wireless network by drawing a diagram so that you know how each AWK-3121 is connected to other peer APs or wireless bridges by WDS, and how bridges are connected to other peer bridges by WDS. See the following figure for an example of a network-planning diagram. 5-2 AirWorks AWK-3121 Users Manual References ATTENTION Be sure to eliminate loops from networks that consist of wireless bridges, Ethernet switches, Ethernet links, and WDS links. If any loops exist, packets will circle around the loops and network performance will be seriously degraded. The following figure shows a network topology containing a loop. Beacon A beacon is a packet broadcast by the AP to keep the network synchronized. A beacon includes the wireless LAN service area, the AP address, the Broadcast destination address, a time stamp, Delivery Traffic Indicator Maps (DTIM), and the Traffic Indicator Message (TIM). Beacon Interval indicates the frequency interval of AP. DTIM Delivery Traffic Indication Map (DTIM) is contained in beacon frames. It is used to indicate that broadcast and multicast frames buffered by the AP will be delivered shortly. Lower settings result in more efficient networking, while preventing your PC from dropping into power-saving sleep mode. Higher settings allow your PC to enter sleep mode, thus saving power. Fragment A lower setting means smaller packets, which will create more packets for each transmission. If you have decreased this value and experience high packet error rates, you can increase it again, but it will likely decrease overall network performance. Only minor modifications of this value are recommended. RTS Threshold RTS Threshold (256-2346) This setting determines how large a packet can be before the Access Point coordinates transmission and reception to ensure efficient communication. This value should remain at its default setting of 2,346. When you encounter inconsistent data flow, only minor modifications are recommended. 5-3 AirWorks AWK-3121 Users Manual STP and RSTP The STP/RSTP Concept References Spanning Tree Protocol (STP) was designed to help reduce link failures in a network, and provide protection from loops. Networks that have a complicated architecture are prone to broadcast storms caused by unintended loops in the network. The STP protocol is part of the IEEE802.1D standard, 1998 Edition bridge specification. The explanation given below uses bridge instead of switch. Rapid Spanning Tree Protocol (RSTP) implements the Spanning Tree Algorithm and Protocol defined by IEEE802.1w-2001 standard. RSTP provides the following benefits:
The topology of a bridged network will be determined much more quickly compared to STP.
RSTP is backward compatible with STP, making it relatively easy to deploy. For example:
Defaults to sending 802.1D-style BPDUs if packets with this format are received.
STP (802.1D) and RSTP (802.1w) can operate on the LAN ports and WLAN ports (AP and WDS1-WDS8) of the same AWK-3121. This feature is particularly helpful when the AWK-3121 connects to older equipment, such as legacy switches. Differences between RSTP and STP RSTP is similar to STP, but includes additional information in the BPDUs that allow each bridge to confirm that it has taken action to prevent loops from forming when it decides to enable a link to a neighboring bridge. Adjacent bridges connected via point-to-point links will be able to enable a link without waiting to ensure that all other bridges in the network have had time to react to the change. The main benefit of RSTP is that the configuration decision is made locally rather than network-wide, allowing RSTP to carry out automatic configuration and restore a link faster than STP. 5-4 66 Chapter 6 Supporting Information This chapter presents additional information about this manual and product.
