Release Notes for Cisco Aironet 350 Series Workgroup Bridges Running Firmware
These release notes describe caveats in firmware maintenance release 8.89 for Cisco Aironet 350 Series Workgroup Bridges. These release notes also contain important information about the device.
These release notes describe the following topics:
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 workgroup bridge connects to a hub through a standard Ethernet port using a 10BASE-T (twisted pair) RJ-45 connector, and up to eight wired Ethernet client devices can be connected to the hub. You can use an Internet browser or Telnet to configure the workgroup bridge.
You must have a Cisco Aironet 350 Series Workgroup Bridge to install firmware version 8.89.
Minimum Firmware Version Required on Access Points
Access points with which the workgroup bridge associates must contain firmware version 11.06 or later.
Upgrading to a New Firmware Release
Finding the Firmware Version
The firmware version number is in the upper-left corner of most management screens in the web-browser interface and at the top of the home (Summary Status) page in the command-line interface.
Obtaining the Workgroup Bridge Image
The workgroup bridge image file can be obtained from the Cisco.com software center using these steps:
Step 1 Follow this link to the Software Center on Cisco.com, and download firmware version 8.89:
Step 2 Click Option 2: Aironet Wireless Software Display Tables.
Step 3 Find the workgroup bridge firmware and utilities section, and click Cisco Aironet 350 Series.
Step 4 Click WGB350v889.exe, the workgroup bridge image file.
Step 5 On the Encryption Authorization Form, enter the requested information, read the encryption information, and check the boxes that apply.
Step 6 Click Submit.
Step 7 Read and accept the terms and conditions of the Software License Agreement.
Step 8 Select the image file again to download it.
Step 9 Download and save the image file to your hard drive, and then exit the Internet browser.
Step 10 Double-click WGB350v889.exe to expand the downloaded file, and record the location where you stored the expanded .img file.
Upgrading the Workgroup Bridge Firmware
Follow these steps to upgrade the workgroup bridge firmware image by using an Internet browser:
Step 1 Open an Internet browser on a computer that is on the same network as the bridge.
Step 2 Enter the bridge IP address in the browserlocation field. Click Enter.
Step 3 When the bridge management home page appears, click Allow Config Changes in the upper-left corner.
Step 4 In the Diagnostics menu, click Load.
Step 5 Enter the path and filename of the new image file in the entry field, such as c:\firmware\WGB350v889.img.
Step 6 Click Send. The workgroup bridge loads the new firmware and reboots.
Step 7 If an error message appears stating that the page cannot be refreshed without resending the information, click Cancel. The workgroup bridge loads the new firmware, and you can ignore the message.
Step 8 To verify that the upgrade is successful, repeat Step 1 and Step 2. When the bridge management home page appears, verify that the new firmware version number (8.89) appears beside the model name in the upper-left corner of the page.
There are no new features in this software maintenance release.
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.
Cisco Aironet Software Requires Completion of Encryption Authorization Form
To access Cisco Aironet software from the Software Center on Cisco.com, you must complete a form to receive authorization to download encrypted software. Registered Cisco.com users are required to fill out the form only once, while public users must do so once each session, each time software is downloaded. A form is automatically created for public users. The form for registered Cisco.com users is at the following URL:
Bridge Loop Can Occur with Incorrect Network Topology
If the workgroup 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 workgroup 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 Workgroup Bridge Connected to the Wired LAN
A bridge loop can also occur if two or more workgroup bridges are connected to the same remote hub. To prevent this bridge loop, always connect only one workgroup bridge to a remote hub.
Figure 2 shows the network configuration in which the bridge loop occurs.

This section describes the resolved caveats for firmware version 8.89.
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:
•CSCea59101—Signal strength test does not display level until a warm reload is performed.
When the workgroup bridge has been running for a day or more, performing the signal strength test does not display the signal level bar unless the unit is restarted (warm reloaded) using the Telnet or browser interface.
The following caveats were resolved in firmware version 8.89:
•CSCee83100—Workgroup bridge does not automatically LEAP reauthenticate after a failure.
•CSCea64630—Workgroup bridge resets to factory defaults by itself.
•CSCed33613—Link tests parameter is reset to factory default by rebooting the workgroup bridge.
For the most up-to-date, detailed troubleshooting information, refer to the Cisco TAC website at this URL (select Product Support > Wireless > Wireless LAN):
This section describes errors, omissions, and changes in user documentation for workgroup bridges.
Staleout Time Setting
The workgroup bridge management system includes a wired LAN staleout time setting on the Configuration > Ethernet page. Use this setting to control the number of seconds that the workgroup 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 workgroup bridge change frequently, enter 300 (equal to five minutes) for the staleout time setting. If you disconnect the Ethernet cable from the workgroup bridge and reconnect it, the workgroup bridge removes all devices from its association table and relearns them, regardless of the staleout time setting.

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
