Introduction

Workgroup bridges are small, standalone units that provide wireless infrastructure connections for Ethernet-enabled devices. A device connected to a bridge communicates with a network infrastructure through Cisco Aironet Access Points.

The bridge connects to a hub through a standard Ethernet port using a 10BASE-T/RJ-45 (twisted pair) connector, and up to eight client devices can be connected to the hub. You can use an Internet browser or Telnet to configure the bridge.

The bridge communicates with Cisco Aironet Access Points, but it does not communicate with wireless networking devices manufactured by other companies.

System Requirements

You must have a Cisco Aironet 340 or 350 Series Workgroup Bridge to install firmware version 8.65_2.

Minimum Firmware Version Required on Access Points

Access points with which the bridge associates must contain firmware version 11.05 or later. The firmware version number appears in the upper-left corner of most access point management screens in the browser interface and at the top of the home (Summary Status) page in the command-line interface.

Upgrading to a New Firmware Release

Determining the Firmware Version

The firmware version number appears in the top left corner of the screen in the browser-based management system. To view the browser-based management system, type the device's IP address in the Internet browser address line.

Upgrade Procedure

Follow these steps to upgrade the firmware in your workgroup bridge:


Step 1 Use one of the following URLs to find firmware version 8.65_2:

http://www.cisco.com/pcgi-bin/tablebuild.pl/aironet-340

or

http://www.cisco.com/pcgi-bin/tablebuild.pl/aironet-350


Caution Make sure you select firmware version 8.65_2 for 340 and 350 series workgroup bridges. Loading firmware version 8.65_2 for 340 series wireless bridges can disable your workgroup bridge.

Step 2 In the Filename column, select and click [firmware version 8.65_2 for workgroup bridges]. Follow the instructions for saving the file to your local drive.

Step 3 Use an Internet browser to open the management system on the bridge. To browse to the management system, type the bridge's IP address in the browser address line and press Enter.

Step 4 When the management system opens, click Allow Config Changes in the top left corner of the page.

Step 5 Click Load in the Diagnostics column near the top of the page.

Step 6 In the Value column, click Browse. Find the local drive where you saved the new firmware version and select the firmware file.

Step 7 Click Send. The new firmware is loaded and the bridge reboots.


New Features

This section describes new features in firmware version 8.65, which are also included in version 8.65_2.

Support for 802.1x Protocol Draft 10

Firmware version 8.65_2 uses 802.1x protocol draft 10. If your workgroup bridge uses Extensible Authentication Protocol (EAP) to log onto a network, the access point with which the bridge associates must use 802.1x protocol draft 10, also.

Installation Notes

Verify Mounting Hole Measurement

If you make a photocopy of the mounting template (included in Mounting Instructions for the Cisco Aironet Access Points, Base Stations, and Workgroup Bridges with Plastic Cases), make sure that the distance between the holes is 4 3/4 in. (12.06 cm) before you drill the holes. Some photocopy machines do not make exact duplicates of the original.

Bridge Loop May Occur with Incorrect Network Topology

If the bridge is connected to the wired LAN and is communicating with an access point on the same LAN, a network problem known as a bridge loop can occur. Avoid a bridge loop by disconnecting the bridge from the wired LAN immediately after you configure it. Figure 1 shows the network configuration in which the loop occurs.

Figure 1 Bridge Loop Caused by a Bridge Connected to the Wired LAN

A bridge loop can also occur if two or more bridges are connected to the same remote hub. To prevent this bridge loop, always connect only one bridge to a remote hub. Figure 2 shows the network configuration in which the loop occurs.

Caveats

This section describes open and resolved caveats for firmware version 8.65_2.

Getting Bug Information on Cisco.com

If you are a Cisco.com registered user, you can use the Cisco TAC Software Bug Toolkit to identify existing bugs (or caveats) in Cisco software products. Access the TAC Software Bug Toolkit at the following URL

http://www.cisco.com/support/bugtools/.

Open Caveats

Distribute Configuration feature fails to distribute configuration to other units (CSCdv07929). Cisco Aironet 340 Series Bridges, 4800 Series Access Points, and 340 and 350 Series Workgroup Bridges fail to distribute a configuration to other units when you select newer for How to control distributions. Workaround: Select any or password for How to control distributions to make sure all units receive the configuration.

Cannot access workgroup bridges associated with access point (CSCdu10993). When a 340 or 350 series workgroup bridge is associated to an access point, you cannot access the bridge console menus or ping the bridge from a station on the wired LAN connected to the access point's Ethernet port. However, you can access the bridge from any client device connected to the bridge's Ethernet port and from any client device associated to the access point that is associated to the bridge. Radio traffic between the access point and the bridge is not affected.

Web-browser interface prompts for password on logout (CSCdu81478). The bridge's web-browser interface prompts you for a password when you log out of the interface. Regardless of the password you enter, the interface reports that the password is incorrect. Workaround: If the password window appears when you logout, click OK without entering a passoword.

Resolved Caveats

Resolved: CSCdw63264--An error can occur with management protocol processing. Please use this URL for further information:

http://www.cisco.com/cgi-bin/bugtool/onebug.pl?bugid=CSCdw63264

The following caveat was resolved in firmware version 8.65 and is also resolved in version 8.65_2:

Resolved: Code Red virus causes lock-up (CSCdv01662). The Code Red Virus attacks 340 and 350 series workgroup bridges, 340, 500, and 4800 series wireless bridges, and 4800 series access points. The unit stops operating and must be rebooted.

Troubleshooting

For the most up-to-date, detailed troubleshooting information, refer to the Cisco TAC website at http://www.cisco.com/tac. Select Wireless LAN under Top Issues.

Documentation Updates

This section describes errors, omissions, and changes in user documentation for workgroup bridges.

Stale Out Time Setting

The bridge's web-browser management system includes a Wired LAN stale out time setting on the Configuration — Ethernet page. Use this setting to control the number of seconds the bridge continues to track a device in its association table when the device is inactive. Enter a value between 5 and 1000 seconds. (Five minutes equals 300 seconds; ten minutes equals 600 seconds.)

If the same devices are always connected to the workgroup bridge, enter 5 for the staleout time setting. If the devices connected to the bridge change frequently, enter 300 (equal to five minutes) for the staleout time setting. If you unplug the Ethernet cable from the bridge and plug it back in, the bridge removes all devices from its association table and re-learns them regardless of the stale out time setting.
