  2 Getting Started       This chapter explains how to install Moxa’s AirWorks TAP-213 for the first time to quickly set up your wireless network and how to test whether the connection is working well. The function map provided in Chapter 3 is a convenient reference to the various functions available on the TAP-213 and to determine the functions that you need to use. The following topics are covered in this chapter:   First-Time Installation and Configuration  Communication Testing  Function Map
Tough AP TAP-213 Getting Started 2-2    First-Time Installation and Configuration Before installing the TAP-213, make sure that all items mentioned in the package checklist are in the box. You will also need access to a notebook computer or PC equipped with an Ethernet port. The TAP-213 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 TAP-213 can be powered by a DC power input or PoE (Power over Ethernet). • Step 2: Connect the TAP-213 to a notebook or PC. Since the TAP-213 is provided with the MDI/MDI-X auto-sensing capability, you can use either a straight-through cable or crossover cable to connect it to a computer. When the connection between the TAP-213 and the computer is established, the LED indicator on the TAP-213’s LAN port lights up. • Step 3: Set up the computer’s IP address. Set an IP address for the computer so that it is on the same subnet as that of the TAP-213. Since the TAP-213’s default IP address is 192.168.127.253, and the subnet mask is 255.255.255.0, set the IP address of the computer in the 192.168.127.xxx IP range and subnet mask to 255.255.255.0. • Step 4: Use the web-based manager to configure the TAP-213 Open your computer’s web browser and type http://192.168.127.253 in the address field to access the homepage of the web-based Network Manager. Before the homepage opens, you will need to enter the user name and password as shown in the following figure. For first-time configuration, enter the following default user name and password and click on the Login button: User Name:  admin Password: moxa       NOTE After you click Submit to apply changes, the web page is refreshed and an (Updated) indicator is displayed next to the page heading along with a blinking reminder to restart the device.        To activate the changes, click Restart and then click Save and Restart after you change the settings. The TAP-213 will take about 30 seconds to complete the reboot process. NOTE For security reasons, we strongly recommend changing the default password. To change the password, select Maintenance Password and follow the instructions on the screen.
Tough AP TAP-213 Getting Started 3-2    • Step 5: Select the operation mode for the TAP-213. By default, the operation mode of the TAP-213 is set to AP. You can change this setting to Client mode at Wireless Settings WLAN Basic Wireless Settings. Detailed information about configuring the TAP-213 is available in Chapter 3. • Step 6: Test the network connection. In the following sections we describe two methods that you can use to test that a network connection has been established.   Communication Testing After installing the TAP-213 you can run a sample test to make sure the wireless connection on the TAP-213 is functioning normally. Two testing methods are described below. Use the first method if you are using only one TAP-213 device and the second method if you are using two or more TAP-213 units.  How to Test One TAP-213  If you are only using one TAP-213, you will need one additional notebook computer equipped with a WLAN card. Configure the WLAN card to connect to the TAP-213 (NOTE: the default SSID is MOXA), and change the IP address of the second notebook (Notebook B) so that it is on the same subnet as the first notebook (Notebook A), which is connected to the TAP-213. After configuring the WLAN card, establish a wireless connection with the TAP-213 and open a DOS window on Notebook B. At the prompt, type the following: 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.
Tough AP TAP-213 Getting Started 4-2     How to Test Two or More TAP-213 Units  If you have two or more TAP-213 units, you will need a second notebook computer (Notebook B) equipped with an Ethernet port. Use the default settings for the first TAP-213 connected to notebook A and change the second or third TAP-213 connected to notebook B to Client mode, and then configure the notebooks and TAP-213 units 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 the latter case, recheck the configuration to make sure the settings are correct.

Tough AP TAP-213 Web Console Configuration 3-2    Web Browser Configuration The web interface provides a convenient way to modify the configuration of the TAP-213 and access its built-in monitoring and network administration functions. The recommended web browser is Microsoft®  Internet Explorer 7.0 or 8.0 with JVM (Java Virtual Machine) installed.    To access the web interface of the TAP-213, do the following:  1. Open a web browser (e.g., Internet Explorer), type in the default IP address of the TAP-213 in the address field, and press Enter.    2. In the login page that is displayed, enter the Username and Password (default Username = admin; default Password = moxa) and click Login to continue.    You may need to wait a few moments for the main page to download to your computer. Note that the model name and IP address of the TAP-213 are both shown in the title bar of the web page. You can identify the web interfaces of multiple TAP-213 units using this information. NOTE To use the management and monitoring functions of the TAP-213 from a PC host connected to the same LAN as the TAP-213, you must make sure that the PC host and the TAP-213 are on the same logical subnet. Similarly, if the TAP-213 is configured on a different VLAN than the PC, you must make sure your PC host is on the management VLAN so that it can access the TAP-213. The default IP address of the TAP is 192.168.127.253.

You must configure these settings correctly before you establish your wireless network. Familiarize yourself with the following terms before starting the configuration process: AP: In a wireless local area network (WLAN), an access point is a station that transmits and receives data.  Client: When the TAP-213 is configured for 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 adaptor but no wireless card can be connected to this device with an Ethernet cable to provide wireless connectivity to another AP.   Operation Mode The TAP-213 supports five main operation modes—AP, Client, and Client-Router, each of which plays a distinct role on the wireless network.    Wireless Enable  Setting Description Factory Default Enable/Disable  Use this function to turn the RF (Radio Frequency) module on or off manually. NOTE: This function is available in AP operation mode only.

Basic Wireless Settings (Multiple SSID) You can add new SSIDs or edit existing ones in the WLAN Basic Setting Selection panel. You can configure up to 9 SSIDs for a TAP and configure each SSID differently. An SSID is a unique identifier that wireless networking devices use to establish and maintain wireless connectivity. Multiple access points on a network or sub-network can use the same SSIDs. All of the SSIDs that you configure for an AP are active at the same time. That is, client devices can use any of the SSIDs to associate with the AP.
Tough AP TAP-213 Web Console Configuration 3-11    To create an SSID for your TAP, click on Add SSID. To edit an existing SSID and assign different configuration settings to it, click on the Edit button corresponding to the SSID. A configuration panel is displayed as follows:     NOTEWhen you switch to Client mode, a Site Survey button will be available on the Basic Wireless Settings panel. Use the Site Survey function to view information about available APs, as shown in the following figures. You can also click on an SSID listed on the Site Survey page to bring the details of the SSID onto the Basic Wireless Settings page. To update the site survey table, click the Refresh button.

Tough AP TAP-213 Web Console Configuration 3-13    WLAN Security Settings The TAP-213 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 TAP-213 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 IEEE 802.1X. The TAP-213 can support three EAP methods: EAP-TLS, EAP-TTLS, and EAP-PEAP.   Security mode  Setting Description Factory Default Open  No authentication  Open WEP  Static WEP is used  WPA  WPA is used  WPA2  Fully supports IEEE 802.11i with “TKIP/AES + 802.1X”   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)    According to the IEEE 802.11 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 TAP-213 provides 4 entities of WEP key settings that can be selected to use with Key index. 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.
Tough AP TAP-213 Web Console Configuration 3-14    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 Default Open  Data encryption is enabled, but without authentication  Open Shared  Data encryption and authentication are both enabled.   Key type  Setting Description Factory Default HEX  Specifies WEP keys in hex-decimal number form  HEX ASCII  Specifies WEP keys in ASCII form   Key length  Setting Description Factory Default 64 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 Default 1-4  Specifies which WEP key is used  Open  WEP key 1-4  Setting Description Factory Default ASCII type: 64 bits: 5 chars 128 bits: 13chars HEX type: 64 bits: 10 hex chars 128 bits: 26 hex chars A string that can be used as a WEP seed for the RC4 encryption engine. None 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 TAP-213 also supports AES algorithms in WPA and WPA2 for better compatibility. Personal versions of WPA/WPA2, also known 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.
Tough AP TAP-213 Web Console Configuration 3-15    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 type  Setting Description Factory Default Personal  Provides Pre-Shared Key-enabled WPA and WPA2  Personal Enterprise  Provides enterprise-level security for WPA and WPA2   Encryption method  Setting Description Factory Default TKIP**  Temporal Key Integrity Protocol is enabled  AES AES  Advance Encryption System is enabled  Mixed*  Provides TKIP broadcast key and TKIP+AES unicast key for some legacy AP clients.

Passphrase  Setting Description Factory Default 8 to 63 characters  Master key to generate keys for encryption and decryption  None  Key renewal (for AP mode only)  Setting Description Factory Default 60 to 86400 seconds (1 minute to 1 day) Specifies the time period of group key renewal  3600 (seconds)
Tough AP TAP-213 Web Console Configuration 3-16    WPA/WPA2-Enterprise (for AP 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.    WPA type  Setting Description Factory Default Personal  Provides Pre-Shared Key-enabled WPA and WPA2  Personal Enterprise  Provides enterprise-level security for WPA and WPA2   Encryption method  Setting Description Factory Default TKIP**  Temporal Key Integrity Protocol is enabled  AES AES  Advance Encryption System is enabled  Mixed*  Provides TKIP broadcast key and TKIP+AES unicast key for some legacy AP clients.

Encryption method  Setting Description Factory Default TKIP**  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 Default TLS  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.
Tough AP TAP-213 Web Console Configuration 3-18    You can use Basic WLAN Setup 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  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 TAP-213 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.
Tough AP TAP-213 Web Console Configuration 3-19    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 Default PAP  Password Authentication Protocol is used  MS-CHAP-V2 CHAP  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 Default Max. 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 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 TAP-213 provides MS-CHAP-V2 merely as an EAP method for inner authentication.
Tough AP TAP-213 Web Console Configuration 3-20    Inner EAP protocol  Setting Description Factory Default MS-CHAP-V2  Microsoft CHAP version 2 is used  MS-CHAP-V2  Anonymous  Setting Description Factory Default Max. 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  Advanced Wireless Settings Additional wireless-related parameters are presented in this section to help you set up your wireless network in detail.    Transmission Rate (for A, B, G, B/G mixed, and N modes only)  Setting Description Factory Default Auto  The TAP-213 senses and adjusts the data rate automatically  Auto Available rates  Users can manually select a target transmission data rate   Multicast Rate (for AP mode only)  Setting Description Factory Default Multicast rate (6M ~ 54M) You can set a fixed multicast rate for the transmission of 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, provided that the wireless clients are capable of handling the configured rate. 6M
Tough AP TAP-213 Web Console Configuration 3-21    NOTE Most countries define a limit for the Equivalent Isotropically Radiated Power (EIRP) for an RF transmitting system. The EIRP should not exceed the allowed value. EIRP = transmission power + antenna gain (dBi).  Guard Interval  Setting Description Factory Default Guard Interval  Guard interval is used to ensure that distinct transmissions do not interfere with one another. You can select the guard interval manually for Wireless-N connections. The two options are Short (400 ns) and Long (800 ns). NOTE: This function can be modified in N mode only. 800 ns.  Maximum transmission power  Setting Description Factory Default Available Power  Users can manually select a target power to mask max output power. Because different transmission rates might have their own max output power, please reference product datasheet. The available setting is from 3 to 26.  dBm/MHz: The density of transmission power in channel width. 12 dBm (-1 dBm/MHz)          Beacon Interval (for AP mode only)  Setting Description Factory Default Beacon Interval (40 to 1000 ms) Indicates the frequency interval of the beacon  100 (ms)  DTIM Interval (for AP mode only)  Setting Description Factory Default Data Beacon Rate (1 to 15) Indicates how often the TAP-213 sends out a Delivery Traffic Indication Message 1  Fragmentation threshold  Setting Description Factory Default Fragment Length (256 to 2346) Specifies the maximum size a data packet before splitting and creating another new packet 2346  RTS threshold  Setting Description Factory Default RTS/CTS Threshold (256 to 2346) Determines how large a packet can be before the Access Point coordinates transmission and reception to ensure efficient communication 2346 NOTE        Transmission power indicates the maximum value of transmission power which the user plans. However, the real transmitted power depends on the radio module and some facts, such as country, regulatory limitations and data rate. Please check the Transmission power in Status > Wireless Status for a real and updated value of transmission power, which the TAP is currently using. You can refer to the related glossaries in the reference section for detailed information about the above-mentioned settings. By setting these parameters properly, you can better tune the performance of your wireless network.
Tough AP TAP-213 Web Console Configuration 3-22    READ THIS BEFORE CHANGING THE DFS SETTING DFS (Dynamic Frequency Selection) is a mechanism to allow unlicensed wireless devices to share spectrum with existing radar systems by detecting radar systems and avoid causing interference with them.  Antenna  Setting Description Factory Default A/B/Both  Specifies the output antenna port. Setting “Antenna” to Auto allows 2x2 MIMO communication under 802.11n and 2T2R* communication in legacy 802.11a/b/g modes. Both *Note: Different from 802.11n’s multiple spatial data stream (2x2 MIMO), which doubles the throughput, 2T2R is transmits/receives the same piece of data on both antenna ports.  WMM  Setting Description Factory Default Enable/Disable  WMM is a QoS standard for WLAN traffic. Voice and video data will be given priority bandwidth when enabled with WMM supported wireless clients.  NOTE: This setting can be enabled/disabled only in A, B, and B/G Mixed modes. For N, G/N Mixed, B/G/N Mixed, and A/N Mixed modes, this setting is enabled by default. Disable        Roaming Priority (Only for AP mode)  Setting Description Factory Default Priority 1/2  The roaming priority should be set based on how the radios are deployed along the trackside. Priority 1: radios along the trackside are deployed with open air radiating antennas. Priority 2: radios along the trackside are deployed with leaky feeder like coverage patterns. Due to the differences in coverage patterns between different deployment scenarios, the roaming priority you select will impact roaming performance. Priority 2  RF Index  Setting Description Factory Default RF Index1/ RF Index 2 In an L3 roaming scenario, trackside APs can be arranged in different VLAN gateways within different subnets. The RF index setting identifies the AP within a particular VLAN gateway. RF Index 1  AeroLink Protection (Only for Client mode)  Setting Description Factory Default Disable/L2/L3 • Enable AeroLink Protection to allow wireless clients on the same LAN network to automatically negotiate with each other and form a redundant wireless communication. For more details, see Status AeroLink Protection Status. • Select L2 for roaming on an L2 trackside network. • Select L3 for roaming on an L3 trackside network. Disabled
Tough AP TAP-213 Web Console Configuration 3-23       When L3 is selected, Virtual LAN IP and Virtual WLAN IP are shown as additional setting parameters.  Virtual LAN IP: This IP should be defined as the gateway IP for onboard devices so that all incoming and outgoing traffic can be routed properly via this common IP in case of any role changes of the onboard clients. All AeroLink protected clients within the same subnet need to be configured with the same virtual LAN IP. Virtual WLAN IP: This IP should be defined as the virtual gateway IP for the wayside router, which can route traffic to any onboard client regardless of the client’s home WAC. This IP only needs to be configured when different clients have to backup each other while the clients are registered to different WAC units. For the router to work properly, all clients and the wayside router will need to be configured to have this routing rule (i.e., to use this virtual WLAN IP). How AeroLink Protection Works In vehicle-to-ground applications, it is essential to minimize system downtime and maximize system availability of the train to ground link to ensure proper communication. Moxa’s AeroLink Protection provides a reliable wireless network-level redundancy protocol to ensure that there will always be a live onboard-to-ground link, even when failures occur:  1. Communication Failover: AeroLink Protection members can negotiate with each other to automatically elect an Active node for data communication. If the Active node is no long capable of sending data across to its access point, it will inform other Backup nodes to resume the communication via another path. 2. Frequency-Interference Failover: This concept is similar to “Communication Failover.” If the communication frequency is interfered with and data can no longer transmit over the Active frequency, it will also resume the connection via another Backup frequency. 3. Device Failover: After handling communication and frequency failures, in order to provide a wireless network free of single points of failure, AeroLink Protection also checks the device status. If the Active node has a power failure, the Backup nodes will automatically resume the wireless communication. 4. Scalable: AeroLink Protection is designed to allow multiple backup paths, making it possible for users to realize a complete redundant wireless network free from all the above failure types. 5. Fast Recovery: In addition to maintaining a redundant wireless network, equally important is providing uninterrupted communication even when a failure occurs. AeroLink Protection is designed to recover any failure in under 300 ms.
Tough AP TAP-213 Web Console Configuration 3-24       Turbo Roaming  Setting Description Factory Default Enable/ Disable  Moxa’s Turbo Roaming can enable rapid handover when the TAP-213, as a client or client-router, roams among a group of APs. Disable  When Turbo Roaming is enabled, Turbo Roaming type, RF type, Dual link option, and Scan channels will be shown as follows. There are two options available for Turbo Roaming type; 50ms (controller-based) that only works with the RTG version of the access point and the WAC-1001 and WAC-2004, and 150ms (client-based) that supports all brands of AP. Dual link reduces the packet-loss rate when roaming between difference APs; this function only works with a single channel roaming structure. The RF type shows the current RF type that this client is using. 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, or B/G Mix mode.)    If you set Turbo Roaming type to 150ms (client-based), three additional roaming parameters, 802.11b/g (or b/a) roaming threshold, 802.11b/g (or b/a) roaming offset, and 802.11b/g (or b/a) roaming alive are shown as follows:
Tough AP TAP-213 Web Console Configuration 3-25    Roaming Parameters  Setting Description Factory Default 802.11b/g (or a) roaming threshold (RSSI) When the current RSSI value is lower than the “roaming threshold,” the client will start the roaming process. -75 802.11b/g (or a) roaming difference (RSSI) When the RSSI of a candidate AP is greater than “the current RSSI value plus the roaming difference,” the client will roam to this new candidate AP. 7 802.11b/g (or a) AP alive check threshold (RSSI) When “AP alive check” is enabled, the client will actively send alive check packets over the wireless network; APs who receive the packets will respond to indicate that they are currently available. By doing this, the client can maintain a ready list of available APs, and then quickly hand over to a new AP once it loses contact with the AP it is currently connected to. -82 Roaming Threshold Concept   T1 = Probing for new AP candidate to connect (background scan) T2 = At this point is when the roaming difference conditions are met and the client will initiate the roaming T3 = At this point the client has successfully roamed over to the new AP2   NOTE When 50 ms Turbo Roaming is enabled without using the WAC-1001 or WAC-2004, the connection between the AP and client will not work.
Tough AP TAP-213 Web Console Configuration 3-26    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 TAP-213 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 Status displays information for the current WLAN certificate, which has been imported into the TAP-213. Nothing will be shown if a certificate is not available. Certificate issued to: Shows the certificate user  Certificate issued by: Shows the certificate issuer  Certificate expiration date: Indicates when the certificate has expired  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 and then click Submit to set the password. 2. The password will be displayed in the Certificate private password field. 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 the import 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 TAP-213 reboots. Even though it has expired, it can still be seen on the Current Certificate.
Tough AP TAP-213 Web Console Configuration 3-27    WAC Settings (AP mode only) Controller-based Turbo Roaming function is automatically enabled when you enable the 50ms Turbo Roaming (controller-based) option on the Wireless Settings > WLAN > Basic Wireless Settings > Edit page. The Primary WAC IP address, Backup WAC IP address, and Roaming domain fields are displayed.   Primary WAC IP address  Setting Description Factory Default IP address  Enter the IP address of the primary WAC-1001 or WAC-2004  None  Backup WAC IP address  Setting Description Factory Default IP address  Enter the IP address of the backup WAC-1001 or WAC-2004  None  Primary WAC IP address  Setting Description Factory Default 6 Hex characters  Specifies the area served by the WAC-1001 or WAC-2004. All related controllers, APs, and clients use this IP address as identification to work and communicate with each other. None  Advanced Settings Several advanced functions are available to increase the functionality of your TAP-213 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 TAP-213 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 TAP 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.
Tough AP TAP-213 Web Console Configuration 3-28    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. 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.
Tough AP TAP-213 Web Console Configuration 3-29    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.  Configuring Virtual LAN VLAN Settings To configure the TAP’s VLAN, use the VLAN Setting page to configure the ports.    Management VLAN ID  Setting Description Factory Default VLAN ID ranges from 1 to 4094 Set the management VLAN of this TAP.  1  Port  Type Description Trunk Port LAN  This port is the LAN port on the TAP.  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.   Port PVID  Setting Description Factory Default VLAN ID ranging from 1 to 4094 Set the port’s VLAN ID for devices that connect to the port. The port can be a LAN port or WLAN ports. 1  VLAN Tagged  Setting Description Factory Default A comma-separated list of VLAN IDs. Each of the VLAN IDs range from 1 to 4094. For example: 1,2,3,4. Specify which VLANs can communicate with this specific VLAN. (Empty)
Tough AP TAP-213 Web Console Configuration 3-30    DHCP Server 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 TAP-213 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 TAP-213 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.

You can set these filters as a firewall to help enhance network security. MAC Filter The TAP-213’s MAC filter is a policy-based filter that can allow or filter out IP-based packets with specified MAC addresses. The TAP-213 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.    Enable  Setting Description Factory Default Enable  Enables MAC filter  Disable Disable  Disables MAC filter   Policy  Setting Description Factory Default Accept  Only the packets fitting the entities on list can be allowed.  Drop Drop  Any packet fitting the entities on list will be denied.
Tough AP TAP-213 Web Console Configuration 3-32    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 TAP-213’s 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 TAP-213 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 192.168.1.255. Remember to check the Active check box for each entity to activate the setting.    Enable  Setting Description Factory Default Enable  Enables IP protocol filter  Disable Disable  Disables IP protocol filter   Policy  Setting Description Factory Default Accept  Only the packets fitting the entities on the list can be allowed  Drop Drop  Any packet fitting the entities on the list will be denied
Tough AP TAP-213 Web Console Configuration 3-33    TCP/UDP Port Filter The TAP-213’s 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 TAP-213 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 than 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.    Enable  Setting Description Factory Default Enable  Enables TCP/UDP port filter  Disable Disable  Disables TCP/UDP port filter   Policy    Setting Description Factory Default   Accept Only the packets fitting the entities on list can be allowed.  Drop   Drop Any packet fitting the entities on list will be denied.   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  Static Route (For Client-Router mode only) The Static Routing page is used to configure TAP-213’s static routing table.    Active Click the checkbox to enable Static Routing.  Destination You can specify the destination IP address.  Netmask This option is used to specify the subnet mask for this IP address.
Tough AP TAP-213 Web Console Configuration 3-34    Gateway The IP address of the router that connects the LAN to an external network.  Metric Use this option to specify a “cost” for accessing the neighboring network.  Interface You can select which interface does your routing rules would be set.   NAT Settings/Port Forwarding (For Client-Router mode only) Network Address Translation (NAT)—or more specifically, one-to-many NAT, NAPT, or PAT—is supported to facilitate the Client-Router operation mode. This feature translates the out-going communication from multiple private IPs to a single external IP (WLAN IP) with randomly assigned port for return traffic.    Port Forwarding is needed to allow external devices to initiate communication. Port Forwarding specifies a static map between external ports (WAN Port) and internal IP/port combos (LAN IP/LAN Port)
Tough AP TAP-213 Web Console Configuration 3-35    Enabling NAT and Port Forwarding provides the following benefits:  • Uses the NAT function to hide the Internal IP address of a critical network or device to increase the level of security of industrial network applications. • Uses the same private IP address for different, but identical, groups of Ethernet devices. For example, 1-to-1 NAT makes it easy to duplicate or extend identical production lines    NAT  Setting Description Factory Default Enable/Disable  Enables or disables the NAT translation  Disable  Port Forwarding Active: Click the checkbox to enable Port Forwarding rule(s). Protocol: Specifies the communication protocol. WAN Port: Specifies the external port to be forwarded to. LAN IP: Specifies the “forward to” LAN IP. LAN Port: Specifies the “forward to” LAN Port.   SNMP Agent The TAP-213 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 TAP-213’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 TAP-213 are shown in the following table. Select the security mode and level that will be used to communicate between the SNMP agent and manager.

Mobile IP Settings The mobile IP technology enables the TAP-213 to roam between Layer 3 networks with a roaming break time less than 50 ms. When the TAP-213 is in client/client router mode, it is a mobile node (MN) that is able to roam across different subnets without changing its IP address. Mobile IP Topology Example:
Tough AP TAP-213 Web Console Configuration 3-38      Terminology Description Mobile Node (MN)  A host or router that changes its location from one network to another. Home network  The network within which the MN receives its identifying IP address (home address) Home address  The IP address assigned to the MN within its home network Foreign network  The network in which an MN is operating when away from its home network Home agent (HA)  A router on the home network that provides services to the MN. The home agent intercepts packets sent to the MN within the home network, encapsulates them, and then tunnels them to the MN. Correspondent Node (CN)  A peer with which a mobile node is communicating Co-located Care-of Address (CCoA) The new IP address of the MN when operating on a foreign network. Binding  The association of the home address with a CCoA    Setting Description Factory Default Mobile IP  Enable/disable mobile IP capability of the client (mobile node) for L3 controller based roaming Disable Subnet Binding  Define a subnet of devices connected behind the client (MN) so that data will be forwarded to the corresponding device subnets. Proper IP planning is required to avoid configuring the subnet binding IP to limit access to the TAP. Disable  Note that when the Mobile IP is enabled, the corresponding AP and WAC (HA) controller will also need to be configured properly (with 50 ms roaming enabled) to ensure correct operation of the L3 roaming network.
Tough AP TAP-213 Web Console Configuration 3-39      Link Fault Pass-Through (for Client mode only) This function means if Ethernet port is link down, wireless connection will be forced to disconnect. Once Ethernet link is recovered, TAP will try to connect to AP. If wireless is disconnected, TAP restarts auto-negotiation on Ethernet port but always stays in the link failure state. Once the wireless connection is recovered, TAP 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 Default Enable  Enables the Link Fault Pass-Through function  Disable Disable  Disables the Link Fault Pass-Through function   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 TAP-213 supports different approaches to warn engineers automatically, such as SNMP trap and e-mail. It also supports two digital inputs to integrate sensors into your system to automate alarms by email.  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.

AeroLink Protection Status (For Client Mode Only) After enabling AeroLink Protection from the Advanced WLAN Setup panel, the following table shows the current state of the AeroLink Protection for easier diagnosis.    An AeroLink Protection member could be in 1 or 7 different states:  Initiation State (Init): Initiates the AeroLink Protection Protocol. Discovering State (Discover): Discovers other AeroLink Protection members for further negotiation. Idle State (Idle): Internal protocol checkpoint. Negotiation State (Nego): Negotiates with other AeroLink Protection members and selects Active node. Backup State (Backup): After negotiation, this node is assigned as the Backup node. All traffic will pass through the Active node. NOTE: When a node is acting as a Backup node, the STATE LED for the node will blink to advertise this fact to nearby support engineers. Active State (Active): After negotiation, this node is assigned Active node status, which means that all traffic will pass through that node. Role Change State (Change): If the Active node is no longer capable of data transmission via the WLAN, the device will enter “change state,” which will result in the device going back to Nego state (likely becoming the Backup device since the active link is down).  Routing Table The Routing Table page shows all routing entries.
Tough AP TAP-213 Web Console Configuration 3-47    LAN Status The LAN Status page shows the LAN information, which includes speed, duplex, link status, and packet status.

Please run Maintenance Console Settings to disable them, as shown in the following figure.
  A References       This chapter provides more detailed information about wireless-related technologies. The information in this chapter can help you manage your TAP-213s 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
Tough AP TAP-213 References A-2    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 of the same TAP-213. This feature is particularly helpful when the TAP-213 connects to older equipment, such as legacy switches.
Tough AP TAP-213 References A-3    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.
