This may be due to improper operation or uncontrollable issues, such as an unexpected shutdown while updating the firmware. To recover the firmware, refer to the “Firmware Recovery” section in Chapter 6. Beeper The beeper emits two short beeps when the system is ready. Reset Button The RESET button is located on the top panel of the AWK-3131A. You can reboot the AWK-3131A 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. 1-6

AirWorks AWK-3131A Introduction • 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-3131A. Relay (Digital Output) The AWK-3131A has one relay output consisting of the 2 terminal block contacts on the top panel, as shown below. These relay contacts are used to forward system failures 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 reasons, the relay circuit is kept open when the AWK-3131A is not powered up.

SSID broadcast (for AP mode only) Setting Description Factory DefaultEnable/ Disable SSID can be broadcast or not Enable NOTE The AWK-3131A-JP (for Japanese frequency bands) only connects SSID-hidden APs for IEEE 802.11a channels, and IEEE 802.11g/n channels 1 to 11. The AWK-3131A-EU (for European frequency bands) only connects SSID-hidden APs for IEEE 802.11b/g/n channels. WLAN Security Settings The AWK-3131A provides four standardized wireless security modes: Open, WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected Access), and WPA2. Several security modes are available in the AWK-3131A by selecting Security mode and WPA type: • Open: No authentication, no data encryption. • WEP: Static WEP (Wired Equivalent Privacy) keys must be configured manually. • WPA/WPA2-Personal: Also known as WPA/WPA2-PSK. You will 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-3131A can support three EAP methods: EAP-TLS, EAP-TTLS, and EAP-PEAP. Security mode Setting Description Factory DefaultOpen No authentication Open WEP Static WEP is used WPA* WPA is used WPA2* Fully supports IEEE802.11i with “TKIP/AES + 802.1X” 3-10

AirWorks AWK-3131A Web Console Configuration Open For security reasons, you should NOT set security mode to Open System, since authentication and data encryption are NOT performed in Open System mode. WEP (only for legacy mode) NOTE Moxa includes WEP security mode only for legacy purposes. WEP is highly insecure and is considered fully deprecated by the Wi-Fi alliance. We do not recommend the use of WEP security under any circumstances. According to the IEEE802.11 standard, WEP can be used for authentication and data encryption to maintain 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 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-3131A 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. The WEP key can be presented in two Key types, 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. Authentication type Setting Description Factory DefaultOpen Data encryption is enabled, but without authentication Open Shared Data encryption and authentication are both enabled. Key type Setting Description Factory DefaultHEX Specifies WEP keys in hex-decimal number form HEX ASCII Specifies WEP keys in ASCII form Key length Setting Description Factory Default64 bits Uses 40-bit secret keys with 24-bit initialization vector 64 bits 128 bits Uses 104-bit secret key with 24-bit initialization vector Key index Setting Description Factory Default1-4 Specifies which WEP key is used Open 3-11

AirWorks AWK-3131A Web Console Configuration WEP key 1-4 Setting Description Factory Default ASCII type: A string that can be used as a WEP seed for the RC4 encryption None 64 bits: 5 chars engine. 128 bits: 13chars HEX type: 64 bits: 10 hex chars 128 bits: 26 hex chars WPA/WPA2-Personal WPA (Wi-Fi Protected Access) and WPA2 represent significant improvements over the WEP encryption method. 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-3131A 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), provide 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 complicated and as long as possible. There must be at least 8 ASCII characters in the Passphrase, and it could go up to 63. For security reasons, this passphrase should only be disclosed to users who need it, and it should be changed regularly.

Passphrase Setting Description Factory Default8 to 63 characters Master key to generate keys for encryption and decryption None Key renewal (for AP/Master mode only) Setting Description Factory Default60 to 86400 seconds Specifies the time period of group key renewal 3600 (seconds)(1 minute to 1 day) 3-12

AirWorks AWK-3131A Web Console Configuration NOTE The key renewal value dictates how often the wireless AP encryption keys should be changed. The security level is generally higher if you set the key renewal value to a shorter number, which forces the encryption keys to be changed more frequently. The default value is 3600 seconds (6 minutes). Longer time periods can be considered if the line is not very busy. WPA/WPA2-Enterprise (for AP/Master mode) By setting WPA type to 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 on a large-scale network. It is not necessary to exchange keys or passphrases.

Encryption method Setting Description Factory DefaultTKIP** Temporal Key Integrity Protocol is enabled TKIP AES Advance Encryption System is enabled **This option is only available with 802.11a/b/g standard. EAP Protocol Setting Description Factory DefaultTLS Specifies Transport Layer Security protocol TLS TTLS Specifies Tunneled Transport Layer Security PEAP Specifies Protected Extensible Authentication Protocol, or Protected EAP 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 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 Status 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 has expired 3-14

AirWorks AWK-3131A Web Console Configuration 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 (EAP-TLS for example), and validate whether the network is trustworthy with digital certificates on the authentication server. This step establishes a tunnel that protects the next step (or “inner” authentication), and consequently is sometimes referred to as “outer” authentication. The TLS tunnel is then used to encrypt an older authentication protocol that authenticates the user for the network. As you can see, digital certificates are still needed for 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-3131A 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 and PEAP. 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, with the true user name only shown through the encrypted channel. Keep in mind that not all client software supports anonymous alteration. Confirm this with the network administrator before you enable identity hiding in TTLS and PEAP. TTL Inner Authentication Setting Description Factory DefaultPAP Password Authentication Protocol is used MS-CHAP-V2CHAP Challenge Handshake Authentication Protocol is used MS-CHAP Microsoft CHAP is used MS-CHAP-V2 Microsoft CHAP version 2 is used Anonymous Setting Description Factory DefaultMax. of 31 characters A distinct name used for outer authentication None User name & Password Setting Description Factory Default User name and password used in inner authentication None 3-15

AirWorks AWK-3131A Web Console Configuration PEAP There are a few differences in the TTLS and PEAP inner authentication procedures. 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-3131A provides MS-CHAP-V2 merely as an EAP method for inner authentication.

Transmission Rate Setting Description Factory DefaultAuto The AWK-3131A senses and adjusts the data rate automatically Auto Available rates Users can manually select a target transmission data rate but does't support when RF type are G/N mixed, B/G/N mixed and A/N mixed. 3-16

AirWorks AWK-3131A Web Console Configuration Multicast Rate Setting Description Factory Default Available rates You can set a fixed multicast rate for the transmission of 6M broadcast and multicast packets on a per-radio basis. This parameter can be useful in an environment where multicast video streaming is occurring in the wireless medium, providing the wireless clients are capable of handling the configured rate Guarding Interval Setting Description Factory Default Guarding Interval Guarding interval is used to ensure that distinct transmissions 800ns. do not interfere with one another. You can select the guarding interval manually for Wireless-N connections. The two options are Short (400ns) and Long (800ns). Transmission Power Setting Description Factory Default Available power Users can manually select a target power to mask max output 10 power. Because different transmission rate would have it own max output power, please reference product datasheet. For 802.11bg, the available setting is from 0 to 20 Beacon Interval (for AP/Master mode only) Setting Description Factory Default Beacon Interval Indicates the frequency interval of the beacon 100 (ms) (40 to 1000 ms) DTIM Interval (for AP/Master mode only) Setting Description Factory Default Data Beacon Rate Indicates how often the AWK-3131A sends out a Delivery 1 (1 to 15) Traffic Indication Message Fragmentation threshold Setting Description Factory Default Fragment Length Specifies the maximum size a data packet before splitting and 2346 (256 to 2346) creating another new packet RTS threshold Setting Description Factory Default RTS/CTS Threshold Determines how large a packet can be before the Access Point 2346 (256 to 2346) coordinates transmission and reception to ensure efficient communication NOTE You can refer to the related glossaries in Chapter 5 for detailed information about the above-mentioned settings. By setting these parameters properly, you can better tune the performance of your wireless network. Transmission distance (for 802.11a/n only) Setting Description Factory DefaultDistance or max. range Specifies the transmission distance or max. range between two 500 for transmission AWK devices. This parameter should be set properly, especially (500 to 2500 m) for long-distance communication. 3-17

AirWorks AWK-3131A Web Console Configuration Noise protection Setting Description Factory Default Enable/Disable Adjusts the interference coping capability of the wireless signal. Disable This option should be enabled for communication distance under 500 meters, and should be disabled for communication distances over 500 meters. NOTE Make sure the same Transmission distance parameters are set in both AP and Client. When this parameter is greater than 500, an optimal algorithm will be enabled to support long-distance transmission. Note that Transmission enhancement only supports 802.11a/n mode; 802.11b/g/n mode is not supported. Transmission enhancement is also recommended to enable communication at both ends when long-distance transmission is required. A high-gain antenna installed at a fixed antenna connector can also improve performance. WMM Setting Description Factory DefaultEnable/Disable WMM is a QoS standard for WLAN traffic. Voice and video data Enable will be given priority bandwidth when enabled with WMM supported wireless clients. Note: WMM will always be enabled under 802.11n mode. Full 11a channel support Setting Description Factory DefaultEnable/Disable “Full 11a channel support” allows users to select one channel Disable from 802.11a, including channels in licensed and unlicensed bands. Turbo Roaming (for Client mode only) Setting Description Factory DefaultEnable/ Disable Moxa’s Turbo Roaming can enable rapid handover when the Disable AWK-3131A, as a client, roams among a group of APs. When Turbo Roaming is enabled, the RF type, AP alive check, and Scan channels will be shown as follows. RF type shows the current RF type that this client is using. AP alive check will check if the AP connection is still available. When this function is enabled, a check will be done every 10 ms. You can set up Scan channels for the APs among which this client is going to roam. There are three Scan channels available. Note that the Scan channels may need to be modified when the RF type is changed. (For example, channel 36 is not available in B, G, N or B/G/N Mix mode.) 3-18

AirWorks AWK-3131A Web Console Configuration Advanced Settings Several advanced functions are available to increase the functionality of your AWK-3131A and wireless network system. A VLAN is a collection of clients and hosts grouped together as if they were connected to the broadcast domains in a layer 2 network. The DHCP server helps you deploy wireless clients efficiently. Packet filters provide security mechanisms, such as firewalls, in different network layers. Moreover, the AWK-3131A can support STP/RSTP protocol to increase reliability across the entire network, and SNMP support can make network management easier. Using Virtual LAN Setting up Virtual LANs (VLANs) on your AWK series increases the efficiency of your network by dividing the LAN into logical segments, as opposed to physical segments. In general, VLANs are easier to manage. The Virtual LAN (VLAN) Concept What is a VLAN? A virtual LAN, commonly known as a VLAN, is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain, regardless of their physical location. A VLAN has the same attributes as a physical LAN, but it allows for end stations to be grouped together even if they are not located on the same network switch. Network reconfiguration can be done through software instead of physically relocating devices. VLANs now extend as far as the reach of the access point signal. Clients can be segmented into wireless sub-networks via SSID and VLAN assignment. A Client can access the network by connecting to an AP configured to support its assigned SSID/VLAN. Benefits of VLANs VLANs are used to conveniently, efficiently, and easily manage your network in the following ways: • Manage adds, moves, and changes from a single point of contact • Define and monitor groups • Reduce broadcast and multicast traffic to unnecessary destinations • Improve network performance and reduce latency • Increase security • Secure network restricts members to resources on their own VLAN • Clients roam without compromising security VLAN Workgroups and Traffic Management The AP assigns clients to a VLAN based on a Network Name (SSID). The AP can support up to 9 SSIDs per radio interface, with a unique VLAN configurable per SSID. The AP matches packets transmitted or received to a network name with the associated VLAN. Traffic received by a VLAN is only sent on the wireless interface associated with that same VLAN. This eliminates unnecessary traffic on the wireless LAN, conserving bandwidth and maximizing throughput. In addition to enhancing wireless traffic management, the VLAN-capable AP supports easy assignment of wireless users to workgroups. In a typical scenario, each user VLAN represents a department workgroup; for example, one VLAN could be used for a marketing department and the other for a human resource department. In this scenario, the AP would assign every packet it accepted to a VLAN. Each packet would then be identified as marketing or human resource, depending on which wireless client received it. The AP would insert VLAN headers or “tags” with identifiers into the packets transmitted on the wired backbone to a network switch. 3-20

AirWorks AWK-3131A Web Console Configuration Finally, the switch would be configured to route packets from the marketing department to the appropriate corporate resources such as printers and servers. Packets from the human resource department could be restricted to a gateway that allowed access to only the Internet. A member of the human resource department could send and receive e-mail and access the Internet, but would be prevented from accessing servers or hosts on the local corporate network. Configuring Virtual LAN VLAN Settings To configure the AWK’s VLAN, use the VLAN Setting page to configure the ports. Management VLAN ID Setting Description Factory DefaultVLAN ID Set the management VLAN of this AWK. 1 ranges from 1 to 4094 Port Type Description Trunk PortLAN This port is the LAN port on the AWK. Yes WLAN This is a wireless port for the specific SSID. This field will refer to the SSID that you have created. If more SSIDs have been created, new rows will be added.

VLAN Tagged Setting Description Factory DefaultA comma-seperated list Specify which VLANs can communicate with this specific VLAN. (Empty) of VLAN IDs. Each of the VLAN IDs range from 1 to 4094. 3-21

AirWorks AWK-3131A Web Console Configuration NOTE The VLAN feature can allow wireless clients to manage the AP. If the VLAN Management ID matches a VLAN ID, then those wireless clients who are members of that VLAN will have AP management access. CAUTION: Once a VLAN Management ID is configured and is equivalent to one of the VLAN IDs on the AP, all members of that User VLAN will have management access to the AP. Be careful to restrict VLAN membership to those with legitimate access to the AP. 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-3131A can act as a simplified DHCP server and easily assign IP addresses to your DHCP 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-3131A 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.

The AWK-3131A 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.

AirWorks AWK-3131A Web Console Configuration RSTP Settings (for Master or Slave mode only) AWK-3131A 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-3131A’s STP/RSTP feature is disabled by default. To be completely effective, you must enable RSTP/STP on every AWK-3131A connected to your network. If AWK-3131A plays a Slave 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-3131As support STP/RSTP in Master or Slave mode 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. RSTP status This field will appear only when selected to operate STP/RSTP. It indicates whether this AWK-3131A is the Root of the Spanning Tree (the root is determined automatically) or not. Bridge priority Setting Description Factory DefaultNumerical value You can increase the bridge priority by selecting a lower 32768 selected number. A higher bridge priority brings a greater chance of by user being established as the root of the Spanning Tree topology. Hello time Setting Description Factory DefaultNumerical value input The root of the Spanning Tree topology periodically sends out a 2 (seconds)by user “hello” message to other devices on the network to check if the (1 – 10 seconds) topology is healthy. Hello time indicates how often the root sends hello messages. Forwarding delay Setting Description Factory DefaultNumerical value input The amount of time this device waits before checking to see if it 15 (seconds)by user should change to a different topology. (4 – 30 seconds) Max. age Setting Description Factory DefaultNumerical value input As a non-root role, if the device has not received a hello 20 (seconds)by user message from the root longer than Max. age, it will reconfigure (6 – 40 seconds) 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 3-26

AirWorks AWK-3131A Web Console Configuration new Spanning Tree topology. Enable RSTP Setting Description Factory Default Enable/ disable Enables or disables the port as a node on the Spanning Tree Disable topology. (unchecked) Port priority Setting Description Factory Default Numerical value Increase this port’s priority as a node on the Spanning Tree 128 selected by user topology by inputting a lower number. Port cost Setting Description Factory Default Enable/ Disable Input a higher cost to indicate that this port is less suitable as a 2000000 node for the Spanning Tree topology Edge port Setting Description Factory Default Checked/ unchecked Sets a port, which no BPDU expectedly goes through, as an unchecked, except edge port 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. 3-27

AirWorks AWK-3131A Web Console Configuration SNMP Agent The AWK-3131A 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-3131A’s MIB can be found in the software CD and supports reading the attributes via SNMP. (Only get method is supported.) SNMP security modes and security levels supported by the AWK-3131A are shown in the following table. Select the security mode and level that will be used to communicate between the SNMP agent and manager.

AirWorks AWK-3131A Web Console Configuration Link Fault Pass-Through (for Client/Slave mode only) This function means if Ethernet port is link down, wireless connection will be forced to disconnect. Once Ethernet link is recovered, AWK will try to connect to AP. If wireless is disconnected, AWK restarts auto-negotiation on Ethernet port but always stays in the link failure state. Once the wireless connection is recovered, AWK will try to recover the Ethernet link. System log will indicate the link fault pass through events in addition to the original link up/down events. Link Fault Pass-Through Setting Description Factory DefaultEnable Enables Link Fault Pass-Through Disable Disable Disables Link Fault Pass-Through 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-3131A 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. System Log System Log Event Types Detail information for grouped events is shown in the following table. You can check the box for Enable log to enable the grouped events. All default values are enabled (checked). The log for system events can be seen in Status  System Log. NOTE RSSI report events (Only for Client mode) is good for site survey stage and need to use special Utility to draw RSSI as a table. But this function would make extra traffic load, we recommend disable this function in normal using. 3-30

Details for each event item can be found in the “System log Event Types” table on page 3-31. 3-33

AirWorks AWK-3131A 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 Factory DefaultV1 SNMP trap defined in SNMPv1 V1 V2 SNMP trap defined in SNMPv2 1st / 2nd Trap server IP/name Setting Description Factory DefaultIP address or host Enter the IP address or name of the trap server used by your None name network. 3-34

AirWorks AWK-3131A Web Console Configuration Save Configuration The following figure shows how the AWK-3131A stores the setting changes into volatile and non-volatile memory. All data stored in volatile memory will disappear when the AWK-3131A is shutdown or rebooted unless they are y. Because the AWK-3131A starts up and initializes with the settings stored in flash memory, all new changes must be saved to flash memory before restarting the AWK-3131A. 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

5 Other Console Considerations This chapter explains how to access the AWK-3131A for the first time. In addition to HTTP access, there are four ways to access AWK-3131A: 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-3131A to a PC’s COM port, can be used if you do not know the AWK-3131A’s IP address. The other consoles can be used to access the AWK-3131A over an Ethernet LAN, or over the Internet. The following topics are covered in this chapter:  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-3131A Other Console Considerations 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-3131A to a PC’s COM port, can be used if you do not know the AWK-3131A’s IP address. It is also convenient to use serial console configurations when you cannot access the AWK-3131A 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-3131A is powered at reversed voltage (ex. -48VDC), even though reverse voltage protection is supported. If you need to connect the RS-232 console at reversed voltage, Moxa’s TCC-82 isolator is your best solution. NOTE We recommend using Moxa PComm (Lite) Terminal Emulator, which can be downloaded free of charge from Moxa’s website. Before running PComm Terminal Emulator, use an RJ45 to DB9-F (or RJ45 to DB25-F) cable to connect the AWK-3131A’s RS-232 console port to your PC’s 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. 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. Click on the Terminal tab, and select VT100 (or ANSI) for Terminal Type. Click on OK to continue. 5-2

AirWorks AWK-3131A Other Console Considerations 4. 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). 5. The AWK-3131A’s 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-3131A and manage the console over a network. To access the AWK-3131A’s functions over the network from a PC host that is connected to the same LAN as the AWK-3131A, you need to make sure that the PC host and the AWK-3131A are on the same logical subnet. To do this, check your PC host’s IP address and subnet mask. NOTE The AWK-3131A’s 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. 5-3

AirWorks AWK-3131A Other Console Considerations 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-3131A’s IP address from the Windows Run window (you may also issue the telnet command from the MS-DOS prompt). 2. When using SSH client (ex. PuTTY), please run the client program (ex. putty.exe) and then input the AWK-3131A’s IP address, specifying 22 for the SSH connection port. 3. 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-3131A supports HTTPS/SSL encryption for all HTTP traffic. Perform the following steps to access the AWK-3131A’s web browser interface via HTTPS/SSL. 1. Open your web browser and type https://<AWK-3131A’s 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. 5-4

AirWorks AWK-3131A Other Console Considerations 3. Select Yes to accept the certificate issued by Moxa IW and then enter the AWK-3131A’s 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-3131A’s functions. Disabling Telnet and Browser Access If you are connecting the AWK-3131A 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. 5-5

A References This chapter provides more detailed information about wireless-related technologies. The information in this chapter can help you administer your AWK-3131As and plan your industrial wireless network better. The following topics are covered in this appendix:  Beacon  DTIM  Fragment  RTS Threshold  STP and RSTP  The STP/RSTP Concept  Differences between RSTP and STP 

AirWorks AWK-3131A References 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. STP and RSTP The STP/RSTP Concept 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. 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-3131A.  This feature is particularly helpful when the AWK-3131A connects to older equipment, such as legacy switches. A-2

AirWorks AWK-3131A References 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. A-3
