AT-TQ2450 Wireless Access Point User’s Guide Management Modes and Methods The access point has two management modes: Stand-alone mode: Access points in the stand-alone mode are managed independently of each other. To configure a unit in this mode, you have to know its IP address or domain name, and the username and password of the manager account. This is the default setting for the access point.
Chapter 1: Overview Starting a Management Session on the Access Point This section explains how to start a management session on the access from your management workstation. The procedure assumes that the access point has already been assigned an IP address. The address can be a static address that was manually assigned to the unit or it can be a dynamic address from a DHCP server. Note If the access point has not been assigned an IP address and is using its default address 192.168.1.
AT-TQ2450 Wireless Access Point User’s Guide Starting the Initial Management Session on the Access Point If you just installed the device and are powering it on for the first time, it queries the subnet on the LAN port for a DHCP server. If a DHCP server responds to its query, the unit uses the IP address the server assigns to it. If there is no DHCP server, the access point uses the default IP address 192.168.1.230. There are a several ways to start the initial management session on the access point.
Chapter 1: Overview Starting the Initial Management Session with a Direct Connection To start the management session with a direct Ethernet connection between your computer and the access port, perform the following procedure: Note If the access point is using PoE, you may not perform this procedure because it involves a direct connection between your computer and the LAN port on the access point.
AT-TQ2450 Wireless Access Point User’s Guide connected to a port that is also a member of that VLAN. If your network is small and does not have VLANs or routers, you may connect your computer to any port on the Ethernet switch. 2. Change the IP address on your computer to 192.168.1.n, where n is a number from 1 to 254, but not 230. Refer to the documentation that accompanies your computer for instructions on how to set the IP address. 3. Set the subnet mask on your computer to 255.255.255.0. 4.

AT-TQ2450 Wireless Access Point User’s Guide Table 3. Modify Radio Settings Window (Continued) Parameter Primary Channel Description Specifies the location of the Primary channel when a radio is operating at 40 MHz. A 40 MHz channel consists of two 20 MHz channels. They are contiguous in the frequency domain and referred to as the Primary and Secondary channels. The Primary channel is used by 802.11n clients that support only a 20 MHz channel bandwidth, and for legacy clients.
Chapter 3: Manage Menu Table 3. Modify Radio Settings Window (Continued) Parameter Short Guard Interval Supported Description Specifies the dead time interval, in nanoseconds, between OFDM symbols. The guard interval prevents Inter-Symbol and Inter-Carrier Interference (ISI, ICI). The 802.11n mode supports a reduction in the interval from 800 nanoseconds, defined in the a and g standards, to 400 nanoseconds. This may provide up to a 10% improvement in data throughput.
AT-TQ2450 Wireless Access Point User’s Guide Table 3. Modify Radio Settings Window (Continued) Parameter Multidomain Regulatory Mode Description Specifies whether a radio should operate in the Multidomain Regulatory Mode (World Mode) and include the country code in its beacons and probe responses. This allows client stations to operate in any country without reconfiguration. This feature only applies to radio 1 because it operates in the g band (2.4 GHz band).
Chapter 3: Manage Menu Table 3. Modify Radio Settings Window (Continued) Parameter Protection Description Enables or disables rules that guarantee that transmissions do not cause interference with legacy stations or applications. The possible settings are describe here: - Auto: This setting enables protection when legacy devices are within range of the radio. - Off: This setting disables the protections. Legacy clients and access points within range may be affected by 802.11n transmissions.
AT-TQ2450 Wireless Access Point User’s Guide Table 3. Modify Radio Settings Window (Continued) Parameter Fragmentation Threshold Description Specifies packet size for fragmentation. The fragmentation threshold lets you control the maximum size of packets the access point transmits. Packets that exceed the threshold are transmitted as multiple 802.11 packets. The range is 256 to 2346 bytes. Setting the threshold to the maximum value effectively disables fragmentation.
Chapter 3: Manage Menu Table 3. Modify Radio Settings Window (Continued) Parameter Transmit Power Description Specifies the transmission power of the access point. The power is selected from a list of percentages, in the range of 1% to 100%. The default is 100%. Here are the guidelines: - High transmission power levels are more cost-effective than low settings because the access point has a greater range. This reduces the number of access points required to cover a particular area.
AT-TQ2450 Wireless Access Point User’s Guide Table 3. Modify Radio Settings Window (Continued) Parameter Broadcast/Multicast Rate Limiting Description Enables or disables rate limiting of broadcast and multicast packets. Here are the guidelines - To activate rate limiting, click the dialog box to add a check mark. To deactivate rate limiting, click the box to remove the check mark. The default setting is disabled.
Chapter 3: Manage Menu Configuring Virtual Access Points Virtual access points (VAPs) function as independent broadcast domains and are the wireless equivalent of Ethernet VLANs. They are seen by clients as independent access points, with their own VIDs, SSIDs, and security methods. Here are the guidelines to VAPs: Each radio can have up to 16 VAPs. Allied Telesis recommends no more than five VAPs per radio. The VAPs are numbered from 0 to 15.
AT-TQ2450 Wireless Access Point User’s Guide Here are the guidelines for VIDs: The range is 1 to 4094. The default is VID 1. You may assign the same VID to more than one VAP. A VAP can have only one VID. The number is ignored for wireless clients who are assigned VIDs from a RADIUS server because VIDs from a RADIUS server take precedence over the number in this field. Consequently, if you configure the security on a VAP to 802.
Chapter 3: Manage Menu 8. If you want to control access to your network through the VAP by filtering clients by their MAC addresses, select the MAC Filtering pulldown menu and select Enabled. To disable MAC address filtering, select Disabled, the default setting. For instructions on how to configure the filter, refer to “Configuring the MAC Address Filter” on page 77. 9. Click the Update button to activate and save your changes on the access point.

Chapter 5: Status Menu Viewing Event Messages A wireless access point is a complex piece of network equipment that includes both hardware and software components. Multiple software features operate simultaneously, interoperating with each other and processing large amounts of network traffic. It is often difficult to determine exactly what is happening when an access point appears not to be operating normally, or what happened when a problem occurred.
AT-TQ2450 Wireless Access Point User’s Guide using non-volatile memory for this purpose can prematurely wear out the memory, which can lead to performance degradation of the unit. For this reason, event messages should only be stored in non-volatile memory when you are troubleshooting a network problem, and only for short periods of time. A better option for permanently storing messages is to use the syslog client on the access point to send the messages to a syslog server on your network.
Chapter 5: Status Menu Figure 35. View Events Generated by this Access Point Window The system messages are displayed in a table in the Events section of the window, from newest to oldest. The columns in the table are described in Table 18. Table 18. Event Messages Table Field Description Time Date and time when a message was generated. Type The severity level of a message. Service The module in the management software that generated the message. Description Description of the message.
AT-TQ2450 Wireless Access Point User’s Guide Configuring the Event Log You can configure the following parameters of the event log: Whether the event messages are stored in volatile or non-volatile memory. The severity of the displayed messages. The number of displayed messages. Whether all the messages are assigned the facility level 0, kernel messages, to make them compatible with the AT-TQ2403 Access Point. To configure the event log, perform the following procedure: 1.
Chapter 5: Status Menu 5. If you want all messages to be assigned the facility 0, kernel messages, to make them compatible with the AT-TQ2403 Access Point, click the Enabled dialog circle for the TQ2403 Compatible parameter.

AT-TQ2450 Wireless Access Point User’s Guide Configuring the HTTP Server The following procedures explain how to enable and disable the HTTP server. You may use the server to manage the access point with your web browser on your computer. The HTTP server is a non-secure management method. The packets exchanged between your web browser and the access point are sent in clear text, leaving them vulnerable to snooping.
Chapter 6: Services Menu Disabling the HTTP Server The following procedure explains how to disable the HTTP server on the access point. Please review the following guidelines before performing the procedure: If you disable the HTTP server while managing the access point with HTTP, your management session is interrupted. To continue managing the unit, you may use either HTTPS or SNMP. If the maximum number of active sessions is set to 1, the default value.
AT-TQ2450 Wireless Access Point User’s Guide Configuring the HTTPS Server The following procedures explain how to enable and disable the HTTPS server. You may use the server to manage the access point with your web browser on your computer. Managing the device with HTTPS is more secure that HTTP because your web browser and the access point use encryption to protect the management packets. The default setting for the server is disabled. The server uses port 443. You may not change that value.
Chapter 6: Services Menu At this point, your web browser may display a security warning message to indicate that it does not consider the access point, which created its own HTTPS certificate, as a trusted certificate authority. If you see a warning message, you should be able to close it and manage the device. To eliminate the message, add the access point as a trusted certificate authority to the web browser. Refer to the web browser documentation for instructions. 9.
AT-TQ2450 Wireless Access Point User’s Guide Configuring the Maximum Number of Active Management Sessions This procedure explains how to configure the maximum number of active management sessions the access point supports at one time. The range is one to ten sessions. The default is one session. You might want to consider increasing the parameter if the access point will be managed by more than one person. The maximum number of active management sessions applies to HTTP and HTTPS sessions.
Chapter 6: Services Menu Configuring the Management Session Timer You should always conclude your management sessions of the access point by logging off so that if you leave your computer unattended, someone cannot use it to make unauthorized changes to the parameter settings of the device. If you forget to log off, the access point has a timer to detect and log off inactive management sessions for you, automatically.
AT-TQ2450 Wireless Access Point User’s Guide Manually Setting the Date and Time If the access point does not have access to an SNTP server, you may set the date and time manually.
