2 2. Getting Started This chapter explains how to install Moxa’s TAP-323 for the first time, quickly set up your wireless network, and test whether or not the connection is running properly. With the function guide, you can easily find the functions you need. The following topics are covered in this chapter:  First-Time Installation and Configuration  Communication Testing  How to Test One TAP-323  How to Test Two or More TAP Units  Function Guide Map

TAP-323 Getting Started 2-2 First-Time Installation and Configuration Take the following steps to configure your TAP-323. Refer to the section Panel Layout of the TAP-323 below to see where the various ports are located on the product. Step 1: Select a power source Connect the TAP-323 to either a 110 to 220 VDC or 110 to 220 VAC power source. Step 2: Connect the TAP-323 to a computer Use either a straight-through or crossover Ethernet cable to connect the TAP-323 to a computer. When the connection between the TAP-323 and the computer is established, the LED indicator on the TAP-323’s LAN port will light up. See the section 10/100BaseT(X) Ethernet Ports below for detailed instructions. Step 3: Set up the computer’s IP address. The computer’s IP address must be on the same subnet as the TAP-323. Since the TAP-323’s default IP address is 192.168.127.253, and the subnet mask is 255.255.255.0, set the computer’s IP address to 192.168.127.252 (for example), and subnet mask to 255.255.255.0. NOTE After you select Maintenance  Load Factory Default and click the Submit button, the TAP-323 will reset to factory default settings and the IP address will also reset to 192.168.127.253. Step 4: Use the web-based manager to configure the TAP-323 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 manager. Enter the User name and Password to open the TAP-323 homepage. If you are configuring the TAP-323 for the first time, enter the following: NOTE Default user name and password: User Name: admin Password: moxa For security reasons, we strongly recommend changing the default password. To do so, select Maintenance  Password, and then follow the on-screen instructions. NOTE After you click Submit to apply changes, the web page will refresh, and then the string “(Updated)” and a blinking reminder will be displayed on the upper-right corner of the page, as illustrated below. To make the changes effective, click Restart and then Save and Restart after you change the settings. About 30 seconds are needed for the TAP-323 to complete its restart process. Step 5: Select the operation mode By default, the TAP-323’s operation mode is set to Wireless redundancy. If you would like to use Wireless bridge or AP mode instead, you can change the setting in Wireless Settings  Operation mode. Detailed information about configuring the TAP-323’s operation mode can be found 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.

TAP-323 Getting Started 2-3 Communication Testing After installing the TAP-323 you can run a sample test to make sure the wireless connection on the TAP-323 is functioning normally. Two testing methods are described below. Use the first method if you are using only one TAP-323 device and the second method if you are using two or more TAP units. How to Test One TAP-323 If you are only using one TAP-323, you will need one additional notebook computer equipped with a WLAN card. Configure the WLAN card to connect to the TAP-323 (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-323. After configuring the WLAN card, establish a wireless connection with the TAP-323 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.

TAP-323 Getting Started 2-4 How to Test Two or More TAP Units If you have one TAP-323 and oneTAP-323 unit, you will need a second notebook computer (Notebook B) equipped with an Ethernet port. Use the default settings for the TAP-323 connected to notebook A and change the TAP-323 connected to notebook B to Client mode, and then configure the notebooks and TAP 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.

After entering the DNS Server’s IP address, you can input the TAP-323’s URL (e.g., http://ap11.abc.com) in your browser’s address field instead of entering the IP address. The Secondary DNS server will be used if the Primary DNS server fails to connect. None Queue Scheduling Setting Description Factory Default Queue Scheduling Weight: This method services all traffic queues, with priority given to the higher priority queues. In most circumstances, the weight method gives precedence to high priority over low priority, but if the high priority traffic does not reach the link capacity, lower priority traffic is not blocked. Strict: This method services high traffic queues first; low priority queues are delayed until no more high priority data needs to be sent. The strict method always gives precedence to high priority over low priority. Strict Enable Checked: Allows data transmission through the port. Unchecked: Immediately shuts off port access. checked Rate limit Select the LAN traffic rate limit (% of max. throughput) for all packets, from the following options: Not Limited, 3%, 5%, 10%, 15%, 25%, 35%, 50%, 65%, 85% No limit Set CoS Checked or unchecked the Moxa TAP for inspecting 802.1p CoS tags in the MAC frame to determine the priority of each frame. unchecked CoS Value (0~7) Maps different CoS values to 4 different egress queues. 0: Low 1: Low 2: Normal 3: Normal 4: Medium 5: Medium 6: High 7: High 0 Flow Control This setting enables or disables flow control for the port when the port’s Speed is set to Auto. The final result will be determined by the Auto process between the Moxa TAP and connected devices. Checked: Enables flow control for this port when the port’s Speed is set to Auto. Unchecked: Disables flow control for this port when the port’s Speed is set to Auto. Unchecked Time Settings The TAP-323 has a time calibration function that can update the date and time information based on an NTP server or the date and time information specified by the user.

TAP-323 Web Console Configuration 3-7 The Current local time shows the TAP-323’s system time when you open this web page. After you update the date and time setting, click on the Set Time button to activate the new date and time. An “(Updated)” string is displayed next to the date and time fields to indicate that the change is complete. Any change in the date and time setting is effective immediately and does not need a system restart. NOTE The TAP-323 has a built-in real time clock (RTC). The RTC is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time. We strongly recommend that users update the Time Settings of the TAP-323 after the initial setup is complete or when the TAP is switched on after a long-term shutdown, especially if the network does not have an Internet connection for accessing a NTP server or there is no NTP server on the LAN. Current local time Setting Description Factory Default User adjustable time The date and time parameters allow configuration of the local time with immediate activation. Use 24-hour format: yyyy/mm/dd hh:mm:ss None Time zone Setting Description Factory Default User selectable time zone The time zone setting allows the conversion from GMT (Greenwich Mean Time) to the local time. GMT ATTENTION Changing the time zone will automatically adjust the Current local time. You should configure the Time zone before setting the Current local time. Daylight saving time Setting Description Factory Default Enable/ Disable Daylight saving time (also known as DST or summer time) involves advancing clocks (usually 1 hour) during the summer time to provide an extra hour of daylight in the afternoon. Disable When Daylight saving time is enabled, the following parameters can be shown: • The Starts at parameter allows users to enter the date that daylight saving time begins. • The Stops at parameter allows users to enter the date that daylight saving time ends. • The Time offset parameter indicates how many hours forward the clock should be advanced.

The 2nd time will be used if the 1st NTP server fails to connect. time.nist.gov Query period Setting Description Factory Default Query period time (1 to 9999 seconds) This parameter determines how often the time is updated from the NTP server. 600 (seconds) Wireless Settings The essential settings for wireless networks are presented in this function group. You must configure the settings correctly before establishing your wireless network. Operation Mode The essential settings for wireless networks are presented in the wireless settings function group. 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. Matching Table for AP’s WLANs: WLAN 1 WLAN 2 Allowable Setting AP AP Allow NOTE TAP-323 units are meant to be used as trackside access points and hence the client operation mode is not supported.

TAP-323 Web Console Configuration 3-9 Wireless Bridge A bridge is a network component that connects two networks. The TAP-323’s bridge operation is based on the AP (Master) and Client (Slave) concept. Both sides of the connection must have the same RF type, SSID, and security settings. For single RF mesh networks, we can use WDS to establish a static bridge link. In this case, the APs at both ends of the WDS link must be configured manually with each other’s MAC addresses. The performance of a single RF bridge will be poor if more nodes are added. The TAP-323’s dual RF bridge concept is different from using a single RF, because the TAP-323 has dual RFs that offer users a cascade link to bridge the two ends without narrowing down the throughput. WLAN 1/WLAN 2 Enable Setting Description Factory Default WLAN1 enable Turn on/off the WLAN 1 radio by selecting Enable or Disable Enable WLAN2 enable Turn on/off the WLAN 2 radio by selecting Enable or Disable WLAN 1/WLAN 2 Operation mode Setting Description Factory Default Master Master mode can build a connection with a Slave that has the same RF type, SSID, and security settings. AP for WLAN 1 Master for WLAN 2 Slave Slave mode can build a connection with a master that has the same RF type, SSID, and security settings. AP The most common mode used by a TAP-323 wherein it plays the role of a wireless AP Basic Wireless Settings (Multiple SSIDs) 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.

TAP-323 Web Console Configuration 3-10 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: RF type Setting Description Factory Default 2.4 GHz B Only supports the IEEE 802.11b standard B/G/N Mixed G Only supports the IEEE 802.11g standard B/G Mixed Supports IEEE 802.11b/g standards, but 802.11g might operate at a slower speed when 802.11b clients are on the network G/N Mixed Supports IEEE 802.11g/n standards, but 802.11n might operate at a slower speed if 802.11g clients are on the network B/G/N Mixed Supports IEEE 802.11b/g/n standards, but 802.11g/n might operate at a slower speed if 802.11b clients are on the network N Only (2.4GHz) Only supports the 2.4 GHz IEEE 802.11n standard 5 GHz A Only supports the IEEE 802.11a standard A/N Mixed Supports IEEE 802.11a/n standards, but 802.11n may operate at a slower speed if 802.11a clients are on the network N Only (5GHz) Only supports the 5 GHz IEEE 802.11n standard Channel (for AP mode only) Setting Description Factory Default The available channels vary with the RF type setting The channel on which the TAP should operate. The TAP-323 plays the role of a wireless AP here. 6 (in B/G/N Mixed mode) Channel Width (for any 11N RF type only) Setting Description Factory Default 20 MHz Select the channel width. If you are not sure, use the 20/40 MHz (Auto) option 20 MHz 20/40 MHz Channel bonding If you have selected 20/40 MHz only in the Channel Width setting, this setting will automatically set the channel based on the Channel setting. SSID Setting Description Factory Default Maximum of 31 characters The SSID of a client and the SSID of the AP must be identical for the client and AP to be able to communicate with each other. MOXA

TAP-323 Web Console Configuration 3-11 SSID broadcast (for AP mode only) Setting Description Factory Default Enable/Disable Use this setting to specify if the SSID can be broadcast or not Enable Management frame encryption Setting Description Factory Default Enable/Disable Enables management frame encryption to protect your wireless network from DoS attacks. This function only works with Moxa's TAP series. Disable 50ms Turbo Roaming (controller-based) Setting Description Factory Default Enable/Disable Determines whether or not the TAP-323 supports 50 ms roaming. This function only works with the WAC-1001, WAC-2004, and TAP series. Disable Wireless Bridge Mode’s Master You can change this AP’s functionality to Enable or Disable on the basic wireless settings page. If AP functionality is set to Enable, the Status will appear as Active, which means that the WLAN is ready to operate in the selected operation mode. For AP functionality settings, click on Edit, as described below. Click on Add SSID and enter a unique SSID to add a virtual SSID to the Master interface to service other clients. Click on Edit to configure the virtual AP interface. WLAN Security Settings The TAP-323 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-323 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.

TAP-323 Web Console Configuration 3-12 The TAP-323 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) 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 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-323 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.

TAP-323 Web Console Configuration 3-13 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 no 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: 13 chars HEX type: 64 bits: 10 HEX chars 128 bits: 26 HEX chars A string that can be used as a WEP seed for an RC4 encryption engine. None

TAP-323 Web Console Configuration 3-14 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-323 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. 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. This option is rarely used. Note: This option is available in AP or Master mode only, and cannot support AES-enabled clients. * This option is only available for legacy mode in APs and does not support AES-enabled clients. ** This option is only available with 802.11a/b/g standard Passphrase Setting Description Factory Default 8 to 63 characters Master key to generate keys for encryption and decryption None Key renewal (for AP or Master 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)

TAP-323 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/WPA2-Enterprise (for AP or Master Mode) By selecting WPA type as Enterprise, you can use EAP (Extensible Authentication Protocol), a framework authentication protocol used by 802.1X to provide network authentication. In these Enterprise-level security modes, a back-end RADIUS (Remote Authentication Dial-In User Service) server is needed if IEEE 802.1X functionality is enabled in WPA /WPA2. The IEEE 802.1X protocol also offers the possibility of carrying out efficient connection authentication on a large-scale network. In this case, it is not necessary to exchange keys or pass phrases. 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 TKIP AES Advance Encryption System is enabled Mixed* Provides TKIP broadcast key and TKIP+AES unicast key for some legacy AP clients. This option is rarely used. * This option is available only for legacy mode in APs and does not support AES-enabled client. ** This option is only available with 802.11a/b/g standard Primary/Secondary RADIUS server IP Setting Description Factory Default The IP address of RADIUS server Specifies the delegated RADIUS server for EAP None

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:

TAP-323 Web Console Configuration 3-17 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 WLAN 1/2  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 expires 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 create a parallel authentication system. As a result, TTLS (Tunneled TLS) and PEAP (Protected EAP) are used to support the use of so-called “legacy authentication methods.” TTLS and PEAP work in a similar way. First, they establish a TLS tunnel, like EAP-TLS, and validate whether the network is trustworthy with digital certificates on the authentication server. This step is run to establish a tunnel that protects the next step (or “inner” authentication) so it is sometimes referred to as the “outer” authentication. Then the TLS tunnel is used to encrypt an older authentication protocol that authenticates the user for the network. As you can see, digital certificates are still needed for the outer authentication in a simplified form. Only a small number of certificates are required, which can be generated by a small certificate authority. Certificate reduction makes TTLS and PEAP much more popular than EAP-TLS. The TAP-323 provides some non-cryptographic EAP methods including PAP, CHAP, MS-CHAP, and MS-CHAP-V2. These EAP methods are not recommended for direct use on wireless networks. However, they may be useful as inner authentication methods with TTLS or PEAP. Because the inner and outer authentications can use distinct user names in TTLS and PEAP, you can use an anonymous user name for the outer authentication, while the true user name is shown only through the encrypted channel. Remember, not all client software supports anonymous altercation. Confirm this with the network administrator before you enable identity hiding in TTLS and PEAP.

TAP-323 Web Console Configuration 3-18 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. 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 inner authentication procedures for TTLS and PEAP. TTLS uses the encrypted channel to exchange attribute-value pairs (AVPs), while PEAP uses the encrypted channel to start a second EAP exchange inside of the tunnel. The TAP-323 provides MS-CHAP-V2 merely as an EAP method for inner authentication.

TAP-323 Web Console Configuration 3-19 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. 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-323 will sense and adjust 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 (6-54 M) 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 configuration rate. 6 M

TAP-323 Web Console Configuration 3-20 Guard Interval Setting Description Factory Default Guard Interval (6-54 M) 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. Multicast Rate (for AP mode only) Setting Description Factory Default Multicast rate (6-54 M) 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 configuration rate. 6 M 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, which gives the density of the transmission power in channel width. 12 dBm (-1 dBm/MHz) 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). Beacon Interval (for AP and Master mode only) Setting Description Factory Default Beacon Interval (40 to 1000 ms) This value indicates the frequency interval of the beacon 100 (ms) DTIM Interval (for AP and Master mode only) Setting Description Factory Default Data Beacon Rate (1 to 15) This value indicates how often the TAP-323 sends out a Delivery Traffic Indication Message 1 Fragment threshold Setting Description Factory Default Fragment Length (256 to 2346) This parameter specifies the maximum size a data packet must be before splitting and creating a new packet 2346 RTS threshold Setting Description Factory Default RTS/CTS Threshold (256-2346) Determines how large a packet can be before the Access Point coordinates transmission and reception to ensure efficient communication 2346 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 transmits/receives the same piece of data on both antenna ports.

TAP-323 Web Console Configuration 3-21 WMM 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.

Voice and video data will be given priority bandwidth when enabled with WMM supported wireless clients. 802.1p Priority WMM Access Category 1 Background 2 0 Best effort 3 4 Video 5 6 Video 7 Disable NOTE 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. Roaming Priority (only for AP mode) Setting Description Factory Default Priority 1/2 The roaming priority should be set according to the radio deployment method along the trackside. Priority 1: radios along the trackside are deployed with leaky feeder-like coverage patterns. Priority 2: radios along the trackside are deployed with open air radiating antennas. Due to the difference in coverage pattern between different deployment scenarios, properly selecting the roaming priority will impact the roaming performance. Priority 2 RF Index Setting Description Factory Default RF Index 1 /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

TAP-323 Web Console Configuration 3-22 WLAN Certification Settings (for EAP-TLS in Slave mode only) When EAP-TLS is used, a WLAN Certificate will be required at the client end to support WPA/WPA2-Enterprise. The TAP-323 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-323. 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 becomes invalid You can import a new WLAN certificate in Import WLAN Certificate by following these steps, in order: 1. Input the corresponding password (or key) in the Certificate private password field, 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-323 reboots. Even though it is expired, it can still be seen on Current Certificate. 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.

All related controllers, APs, and clients use this as identification to work and communicate with each other None Advanced Settings Several advanced functions are available to increase the functionality of your TAP-323 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-323 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, or VLAN, is a collection of hosts with a common set of requirements. The hosts 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 you to group end stations together even if they are not connected to the same network switch. Network reconfiguration can be done through software instead of physically relocating devices. VLANs can extend as far as the access point signal can reach. Clients can be segmented into wireless sub-networks based on 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 networks limit members to using resources on their own VLAN • Clients can roam without compromising security

TAP-323 Web Console Configuration 3-24 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, eliminating 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 resources 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 resources, 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 resources department could be restricted to a gateway that allowed access to only the Internet. A member of the human resources department could send and receive email and access the Internet, but would be prevented from accessing servers or hosts on the local corporate network.

TAP-323 Web Console Configuration 3-25 Configuring a Virtual LAN VLAN Settings To configure a VLAN on the AWK, use the VLAN Settings 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 AWK. 1 Port Type Description Trunk Port LAN 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. 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 VLAN ID must be between 1 and 4094. Specify which VLANs can communicate with this specific VLAN. (Empty) 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.

TAP-323 Web Console Configuration 3-26 DHCP Server (for AP operation 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 TAP-323 can act as a simplified DHCP server and easily assign IP addresses to your wireless clients by responding to the DHCP requests from the client ends. The IP-related parameters you set on this page will also be sent to the client. You can also assign a static IP address to a specific client by entering its MAC address. The TAP-323 provides a Static DHCP mapping list with up to 16 entities. Remember 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. DHCP server (AP only) Setting Description Factory Default Enable Enables TAP-323 as a DHCP server Disable Disable Disables the DHCP server function Default gateway Setting Description Factory Default IP address of a default gateway The IP address of the router that connects to an outside network None Subnet mask Setting Description Factory Default subnet mask Identifies the type of sub-network (e.g., 255.255.0.0 for a Class B network, or 255.255.255.0 for a Class C network) None

TAP-323 Web Console Configuration 3-27 Primary/ Secondary DNS server Setting Description Factory Default IP address of Primary/ Secondary DNS server The IP address of the DNS Server used by your network. After entering the DNS Server’s IP address, you can use URLs. The Secondary DNS server will be used if the Primary DNS server fails to connect. None Start IP address Setting Description Factory Default IP address Indicates the starting IP address that the TAP-323 can assign. None Maximum number of users Setting Description Factory Default 1 to 128 users Specifies how many IP addresses can be assigned continuously None Client lease time Setting Description Factory Default 5 – 1440 minutes The lease time for which an IP address is assigned. The IP address may expire after the lease time is reached. 5 minutes Packet Filters The TAP-323 includes various filters for IP-based packets going through LAN and WLAN interfaces. You can set these filters as a firewall to help enhance network security. MAC Filter The TAP-323’s MAC filter is a policy-based filter that can allow or filter out IP-based packets with specified MAC addresses. The TAP-323 provides eight fields for filtered MAC addresses. 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 from the listed addresses will be allowed. Drop Drop Any packet from the listed addresses will be denied.

TAP-323 Web Console Configuration 3-28 ATTENTION Be careful when you enable the filter function: Drop + “no entity on list is activated” = all packets are allowed (i.e., drop nothing) Accept + “no entity on list is activated” = all packets are denied (i.e., accept nothing) IP Protocol Filter The TAP-323’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-323 provides eight fields for setting IP protocol and source/destination IP addresses in your filtering policy. Four IP protocols are available: All, ICMP, TCP, and UDP. You must specify either the Source IP or the Destination IP. By combining IP addresses and netmasks, you can specify a single IP address or a range of IP addresses to accept or drop. For example, “IP address 192.168.1.1 and netmask 255.255.255.255” refers to the sole IP address 192.168.1.1. “IP address 192.168.1.1 and netmask 255.255.255.0” refers to the range of IP addresses from 192.168.1.1 to 192.168.255. Remember to check the Active check box for each entity to activate the setting. 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 from the listed addresses will be allowed Drop Drop Any packet from the listed addresses will be denied ATTENTION Be careful when you enable the filter function: Drop + “no entity on list is activated” = all packets are allowed (i.e., drop nothing) Accept + “no entity on list is activated” = all packets are denied (i.e., accept nothing)

TAP-323 Web Console Configuration 3-29 TCP/UDP Port Filter The TAP-323’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-323 provides eight fields 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 packets from the listed ports are allowed. Drop Drop Any packet from the listed ports will be denied. ATTENTION Be careful when you enable the filter function: Drop + “no entity on list is activated” = all packets are allowed (i.e., drop nothing) Accept + “no entity on list is activated” = all packets are denied (i.e., accept nothing) Introduction to Redundancy Protocol Setting up Redundancy Protocol on your network helps protect critical links against failure, protects against network loops, and keeps network downtime at a minimum. Redundancy Protocol allows you to set up redundant loops in the network to provide a backup data transmission route in the event that a cable is inadvertently disconnected or damaged. This is a particularly important feature for industrial applications, since it could take several minutes to locate the disconnected or severed cable. For example, if the Moxa TAP-323 is used as a key communications component of a production line, several minutes of downtime could cause a big loss in production and revenue. The Moxa TAP-323 supports two protocols to support this Redundancy Protocol function: • Turbo Chain • Rapid Spanning Tree and Spanning Tree Protocols (IEEE 802.1W/802.1D-2004) When configuring a redundant chain, all APs on the same chain must be configured to use the same redundancy protocol. You cannot mix the Turbo Chain and STP/RSTP protocols on the same chain.

TAP-323 Web Console Configuration 3-30 The following table lists the key differences between the features of each protocol. Use this information to evaluate the benefits of each, and then determine which features are most suitable for your network. redundancy protocol. You cannot mix the Turbo Chain and STP/RSTP protocols on the same chain. The following table lists the key differences between the features of each protocol. Use this information to evaluate the benefits of each, and then determine which features are most suitable for your network. Turbo Chain RSTP Topology Chain Ring, Mesh Fast Ethernet Recovery Time <20 ms Up to 5 sec. Gigabit Ethernet Recovery Time <50 ms The STP/RSTP Concept Spanning Tree Protocol (STP) was designed to help reduce link failures on a network, and provide an automatic means of avoiding loops. This is particularly important for networks that have a complicated architecture, since unintended loops in the network can cause broadcast storms. Moxa switches’ STP feature is disabled by default. To be completely effective, you must enable RSTP/STP on every Moxa switch connected to your network. Rapid Spanning Tree Protocol (RSTP) implements the Spanning Tree Algorithm and Protocol defined by IEEE 802.1D-2004. RSTP provides the following benefits: • The topology of a bridged network will be determined much more quickly compared to STP. • RSTP is backwards 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 different ports of the same switch, which is particularly helpful when switch ports connect to older equipment such as legacy switches. You get essentially the same functionality with RSTP and STP. To see how the two systems differ, see the Differences between STP and RSTP section in this chapter. NOTE The STP protocol is part of the IEEE Std. 802.1D, 2004 Edition bridge specification. The following explanation uses “bridge” instead of “switch.” What is STP? STP (802.1D) is a bridge-based system that is used to implement parallel paths for network traffic. STP uses a loop-detection process to: • Locate and then disable less efficient paths (i.e., paths that have a lower bandwidth). • Enable one of the less efficient paths if a more efficient path fails.

TAP-323 Web Console Configuration 3-31 The figure below shows a network made up of three LANs separated by three bridges. Each segment uses at most two paths to communicate with the other segments. Since this configuration can give rise to loops, the network will overload if STP is NOT enabled. If STP is enabled, it will detect duplicate paths and prevent, or block, one of the paths from forwarding traffic. In the following example, STP determined that traffic from LAN segment 2 to LAN segment 1 should flow through bridges C and A since this path has a greater bandwidth and is therefore more efficient.

TAP-323 Web Console Configuration 3-32 What happens if a link failure is detected? As shown in next figure, the STP process reconfigures the network so that traffic from LAN segment 2 flows through bridge B. STP will determine which path between each bridged segment is most efficient, and then assign a specific reference point on the network. When the most efficient path has been identified, the other paths are blocked. In the previous 3 figures, STP first determined that the path through bridge C was the most efficient, and as a result, blocked the path through bridge B. After the failure of bridge C, STP re-evaluated the situation and opened the path through Bridge B. How STP Works When enabled, STP determines the most appropriate path for traffic through a network. The way it does this is outlined in the sections below. STP Requirements Before STP can configure the network, the system must satisfy the following requirements: • All bridges must be able to communicate with each other. The communication is carried out using Bridge Protocol Data Units (BPDUs), which are transmitted in packets with a known multicast address. • Each bridge must have a Bridge Identifier that specifies which bridge acts as the central reference point, or Root Bridge, for the STP system—bridges with a lower Bridge Identifier are more likely to be designated as the Root Bridge. The Bridge Identifier is calculated using the MAC address of the bridge and a priority defined for the bridge. For example, the default priority setting of Moxa switches is 32768. • Each port has a cost that specifies the efficiency of each link. The efficiency cost is usually determined by the bandwidth of the link, with less efficient links assigned a higher cost.

TAP-323 Web Console Configuration 3-33 STP Calculation The first step of the STP process is to perform calculations. During this stage, each bridge on the network transmits BPDUs. The following items will be calculated: • Which bridge should be the Root Bridge? The Root Bridge is the central reference point from which the network is configured. • The Root Path Costs for each bridge. This is the cost of the paths from each bridge to the Root Bridge. • The identity of each bridge’s Root Port. The Root Port is the port on the bridge that connects to the Root Bridge via the most efficient path. In other words, the port connected to the Root Bridge via the path with the lowest Root Path Cost. The Root Bridge, however, does not have a Root Port. • The identity of the Designated Bridge for each LAN segment. The Designated Bridge is the bridge with the lowest Root Path Cost from that segment. If several bridges have the same Root Path Cost, the one with the lowest Bridge Identifier becomes the Designated Bridge. Traffic transmitted in the direction of the Root Bridge will flow through the Designated Bridge. The port on this bridge that connects to the segment is called the Designated Bridge Port. STP Configuration After all of the bridges on the network agree on the identity of the Root Bridge, and all other relevant parameters have been established, each bridge is configured to forward traffic only between its Root Port and the Designated Bridge Ports for the respective network segments. All other ports are blocked, which means that they will not be allowed to receive or forward traffic. STP Reconfiguration Once the network topology has stabilized, each bridge listens for Hello BPDUs transmitted from the Root Bridge at regular intervals. If a bridge does not receive a Hello BPDU after a certain interval (the Max Age time), the bridge assumes that the Root Bridge, or a link between itself and the Root Bridge, has ceased to function. This will trigger the bridge to reconfigure the network to account for the change. If you have configured an SNMP trap destination, the first bridge to detect the change will send out an SNMP trap when the topology of your network changes. Differences between STP and RSTP 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. STP and RSTP spanning tree protocols operate without regard to a network’s VLAN configuration, and maintain one common spanning tree throughout a bridged network. Thus, these protocols map one loop-free, logical topology on a given physical topology.

TAP-323 Web Console Configuration 3-34 STP Example The LAN shown in the following figure has three segments, with adjacent segments connected using two possible links. The various STP factors, such as Cost, Root Port, Designated Bridge Port, and Blocked Port are shown in the figure. • Bridge A has been selected as the Root Bridge, since it was determined to have the lowest Bridge Identifier on the network. • Since Bridge A is the Root Bridge, it is also the Designated Bridge for LAN segment 1. Port 1 on Bridge A is selected as the Designated Bridge Port for LAN Segment 1. • Ports 1 of Bridges B, C, X, and Y are all Root Ports since they are nearest to the Root Bridge, and therefore have the most efficient path. • Bridges B and X offer the same Root Path Cost for LAN segment 2. However, Bridge B was selected as the Designated Bridge for that segment since it has a lower Bridge Identifier. Port 2 on Bridge B is selected as the Designated Bridge Port for LAN Segment 2. • Bridge C is the Designated Bridge for LAN segment 3, because it has the lowest Root Path Cost for LAN Segment 3: • The route through bridges C and B costs 200 (C to B=100, B to A=100) • The route through bridges Y and B costs 300 (Y to B=200, B to A=100) • The Designated Bridge Port for LAN Segment 3 is port 2 on bridge C.

TAP-323 Web Console Configuration 3-35 RSTP/Turbo Chain Settings (For Master or Slave Mode Only) The TAP-323 supports IEEE 802.1D Spanning Tree Protocol and IEEE 802.1w Rapid STP standards. In addition to eliminating unexpected path looping, STP/RSTP can provide a backup recovery path if a wired/wireless path fails accidentally. This fail-over function can increase the reliability and availability of the network. The TAP-323 also supports Turbo Chain on its fiber interfaces. The TAP-323’s STP/RSTP feature is disabled by default. To be completely effective, you must enable RSTP/STP on every TAP-323 connected to your network. The following figures indicate which Spanning Tree Protocol parameters can be configured. A more detailed explanation of each parameter is given below the figure. Bridge priority Setting Description Factory Default Numerical value selected by user Increase this device’s bridge priority by selecting a lower number. A device with a higher bridge priority has a greater chance of being established as the root of the Spanning Tree topology. 32768 Hello time Setting Description Factory Default Numerical value input by user (1 to 10 seconds) The root of the Spanning Tree topology periodically sends out a “hello” message to other devices on the network to check if the topology is healthy. The “hello time” is the amount of time the root waits between sending hello messages. 2 (seconds) Forwarding delay Setting Description Factory Default Numerical value input by user (4 to 30 seconds) The amount of time this device waits before checking to see if it should change to a different state. 15 (seconds) Max. age Setting Description Factory Default Numerical value input by user (6 to 40 seconds) If this device is not the root, and it has not received a hello message from the root in an amount of time equal to “Max. Age,” then this device will reconfigure itself as a root. Once two or more devices on the network are recognized as a root, the devices will renegotiate a new Spanning Tree topology. 20 (seconds)

TAP-323 Web Console Configuration 3-36 Enable RSTP Setting Description Factory Default Enable/Disable Select to enable the port as a node on the Spanning Tree topology. Disable Port priority Setting Description Factory Default Numerical value selected by user Increase this port’s priority as a node on the Spanning Tree topology by inputting a lower number. 128 Port cost Setting Description Factory Default Numerical value input by user Input a higher cost to indicate that this port is less suitable as a node for the Spanning Tree topology 20000 Edge port Setting Description Factory Default Checked/unchecked Sets a port, which no BPDU is expected to go through, as an edge port unchecked, except WLAN1/2 ports NOTE We recommend that you use the edge port setting for ports that are only connected to non-STP/RSTP sub-networks or end devices (PLCs, RTUs, etc.) as opposed to network equipment. This can prevent unnecessary waiting and negotiation for the 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. The Turbo Chain Concept Moxa’s Turbo Chain is an advanced software-technology that gives network administrators the flexibility of constructing any type of redundant network topology. When using the “chain” concept, you first connect the APs in a chain and then simply link the two ends of the chain to an Ethernet network, as illustrated in the following figure. Turbo Chain can be used on industrial networks that have a complex topology. If the industrial network uses a multi-ring architecture, Turbo Chain can be used to create flexible and scalable topologies with a fast media-recovery time.

TAP-323 Web Console Configuration 3-37 Setting Up a Turbo Chain 1. Select the Head AP, Tail AP, and Member AP. 2. Configure one port as the Head port and one port as the Member port in the Head AP, configure one port as the Tail port and one port as the Member port in the Tail AP, and configure two ports as Member ports in each of the Member switches. 3. Connect the Head AP, Tail AP, and Member APs as shown in the above diagram. The path connecting to the Head port is the main path, and the path connecting to the Tail port is the backup path of the Turbo Chain. Under normal conditions, packets are transmitted through the Head Port to the LAN network. If any Turbo Chain path is disconnected, the Tail Port will be activated so that packet transmission can continue. Configuring “Turbo Chain” Use the scrollbar at the top of the Redundancy Protocol page to select Turbo Chain and RSTP. Note that the configuration pages for these two protocols are different. Protocol Setting Description Factory Default Turbo Chain Select this item to change to the Turbo Chain configuration page. None RSTP (IEEE 802.1D-2004) Select this item to change to the RSTP configuration page.

TAP-323 Web Console Configuration 3-39 SNMP Agent The TAP-323 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-323’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-323 are shown in the following table. Select the security mode and level that will be used to communicate between the SNMP agent and manager. Protocol Version Setting on UI web page Authentication Type Data Encryption Method SNMP V1, V2c V1, V2c Read Community Community string No Use a community string match for authentication V1, V2c Write/Read Community Community string No Use a community string match for authentication SNMP V3 No-Auth None No Use admin or user account to access objects MD5 or SHA Authentication based on MD5 or SHA No Provides authentication based on HMAC-MD5, or HMAC-SHA algorithms. 8-character passwords are the minimum requirement for authentication. MD5 or SHA Authentication based on MD5 or SHA Data encryption key Provides authentication based on HMAC-MD5 or HMAC-SHA algorithms, and data encryption key. 8-character passwords and a data encryption key are the minimum requirements for authentication and encryption. The following parameters can be configured on the SNMP Agent page. A more detailed explanation of each parameter is given below the following figure.

Admin private key (for V1, V2c, V3, and V3 only) Setting Description Factory Default Disable No data encryption Disable DES DES-based data encryption AES AES-based data encryption Private Key A data encryption key is the minimum requirement for data encryption (maximum of 63 characters). Private MIB Information Device Object ID Also known as an OID. This is the TAP-323’s enterprise value and is a fixed value. PoE Settings The TAP-323 has 4 PSE ports that can supply PoE power to PD devices, such as video cameras, on the trackside.

TAP-323 Web Console Configuration 3-41 PoE Enable Setting Description Factory Default Enable/Disable Enable or disable the LAN port (LAN1 to LAN4) for PoE Enable Mobile IP Settings The mobile IP technology enables the TAP-323 to roam between Layer 3 networks with a roaming break time less than 50 ms. When the TAP-323 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: 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

TAP-323 Web Console Configuration 3-42 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. 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. This way 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-323 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.

TAP-323 Web Console Configuration 3-43 System Log System Log Event Types Detailed information for grouped events is shown in the following table. You can check the Enable log box to enable event groups. By default all the values are enabled (checked). The log for system events can be seen in Status  System Log.

TAP-323 Web Console Configuration 3-44 Syslog This function provides the event logs for the Syslog server. The function supports up to three configurable Syslog servers and Syslog server UDP port numbers. When an event occurs, the event will be sent as a Syslog UDP packet to the specified Syslog servers. Syslog Event Types Detailed information for the grouped events is shown in the following table. You can check the Enable log box to enable event groups. By default all values are enabled (checked). Details for each event group can be found on the “System log Event Types” table on page 3-31. Syslog Server Settings You can configure the parameters for your Syslog servers on this page. Syslog server 1/2/3 Setting Description Factory Default IP address Enter the IP address of the 1st/ 2nd/ 3rd Syslog Server None Syslog port Setting Description Factory Default Port destination (1 to 65535) Enter the UDP port of the corresponding Syslog server 514

Details for each event item can be found on the “System log Event Types” table on page 3-24. E-mail Server Settings You can set up to four email addresses to receive alarm emails from the TAP-323. The following parameters can be configured on the E-mail Server Settings page. In addition, a Send Test Mail button can be used to test whether the Mail server and email addresses are working. More detailed explanations about these parameters are given after the following figure. Mail server (SMTP) Setting Description Factory Default IP address The IP Address of your email server. None

TAP-323 Web Console Configuration 3-46 User name & Password Setting Description Factory Default User name and password used in the SMTP server None From e-mail address Setting Description Factory Default Max. 63 characters Enter the administrator’s email address, which will be shown in the “From” field of a warning email. None To E-mail address 1/ 2/ 3/ 4 Setting Description Factory Default Max. 63 characters Enter the receivers’ email addresses. None 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 overwhelming for the management station to poll or send requests to query every object on every device. It would be more effective for the managed device agent to notify the management station when necessary by sending a message known as a trap. Trap Event Types

TAP-323 Web Console Configuration 3-47 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 Default V1 SNMP trap defined in SNMPv1 V1 V2 SNMP trap defined in SNMPv2 1st / 2nd Trap server IP/name Setting Description Factory Default IP address or host name Enter the IP address or name of the trap server used by your network.

The status will refresh every 5 seconds if the Auto refresh box is checked. Depending on the operation mode, certain 802.11 info values may not be displayed. For example, the Current BSSID and Signal strength parameters are not available in the AP mode. It is helpful to use the continuously updated information option on this page, such as Signal strength, to monitor the signal strength of the TAP-323 in Slave mode. The transmission power indicated is the current transmission power being updated periodically.

5 5. Using Other Consoles This chapter explains how to access the TAP-323 for the first time. In addition to HTTP access, there are four ways to access the TAP-323: USB console, Telnet console, SSH console, and HTTPS console. The USB console connection method, which requires using a short USB cable to connect the TAP-323 to a PC’s COM port, can be used if you do not know the TAP-323’s IP address. The other consoles can be used to access the TAP-323 over an Ethernet LAN, or over the Internet. The following topics are covered in this chapter:  USB Console Configuration (115200, None, 8, 1, VT100)  Configuration via Telnet and SSH Consoles

5-2 USB Console Configuration (115200, None, 8, 1, VT100) The USB console connection method, which requires using a short USB cable to connect the TAP-323 to a PC’s COM port, can be used if you do not know the TAP-323’s IP address. It is also convenient to use USB console configurations when you cannot access the TAP-323 over Ethernet LAN, such as in the case of LAN cable disconnections or broadcast storming over the LAN. NOTE We recommend using the Moxa PComm (Lite) Terminal Emulator, which is available for download at: http://www.moxa.com/product/download_pcommlite_info.htm. Before running PComm Terminal Emulator, use an M12 5-pin B-coded to USB type A cable to connect the TAP-323’s USB 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 USB console utility. 1. From the Windows desktop, open the Start menu and run the PComm Terminal Emulator from the PComm (Lite) group. 2. In the Port Manager menu, select Open 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. NOTE -The USB driver is available for download at: http://www.moxa.com/product/UPort_2210.htm -You will see two COM ports. Select the first port (COM1) to connect to the TAP-323 USB console. The COM2 port is reserved for future use.

5-3 4. The Console login screen will appear. Log into the USB console with the login name (default: admin) and password (default: moxa, if no new password is set). 5. The TAP-323’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 USB 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.

5-4 Configuration via Telnet and SSH Consoles You may use Telnet or SSH client to access the TAP-323 and manage the console over a network. To access the TAP-323’s functions over the network from a PC host that is connected to the same LAN as the TAP-323, you need to make sure that the PC host and the TAP-323 are on the same logical subnet. To do this, check your PC host’s IP address and subnet mask. NOTE The TAP-323’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. Follow the steps below to access the console utility via Telnet or SSH client. 1. From Windows Desktop, go to Start  Run, and then use Telnet to access the TAP-323’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 TAP-323’s IP address, specifying 22 for the SSH connection port. The console login screen is displayed. Refer to the USB Console Configuration section for login and administration information. 3. Log in into the command page (default username/password is admin/moxa, if no new password is set). TAP-323 supports the CLI mode. You can use the TAB key to check a related CLI command.

5-5 Configuration by Web Browser with HTTPS/SSL To secure your HTTP access, the TAP-323 supports HTTPS/SSL encryption for all HTTP traffic. Perform the following steps to access the TAP-323’s web browser interface via HTTPS/SSL. 1. Open your web browser and type https://<TAP-323’s IP address> in the address field. Press Enter to establish the connection. 2. Click on continue to this website. The protocol in the URL changes to HTTPS. You can now enter your username and password to login into the function page.

5-6 Disabling Telnet and Browser Access If you are connecting the TAP-323 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.

A A. References This chapter provides more detailed information about wireless-related technologies. The information in this chapter can help you manage your TAP-323s 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

TAP-323 UM 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 The 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-323. This feature is particularly helpful when the TAP-323 connects to older equipment, such as legacy switches.
