Release Notes for Cisco Aironet Workgroup Bridges Running Firmware Release 8.84
May 9, 2003
These release notes describe features and caveats contained in the firmware maintenance release 8.84 for Cisco Aironet 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/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 workgroup bridge.
You must have a Cisco Aironet 350 Series Workgroup Bridge to install firmware version 8.84.
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

This section describes new features in firmware version 8.84.
EAP Authentication Requires Matching 802.1X Protocol Drafts
Note This section applies to wireless networks set up to use LEAP. If you do not use LEAP on your wireless network, you can skip this section.
Wireless client devices use Extensible Authentication Protocol (EAP) to log onto a network and generate a dynamic, client-specific WEP key for the current logon session. If you use Network-EAP authentication on your wireless network, your client devices and access points must use the same 802.1X protocol draft. Version 8.84 requires the 802.1X-2001 draft.
Use the Authenticator Configuration page in the access point firmware to select the draft of the 802.1X protocol the access point radio should use.
Follow these steps to set the draft for your access point.
Step 1 Browse to the Authenticator Configuration page in the access point management system.
a. On the Summary Status page, click Setup.
b. On the Setup page, click Security.
c. On the Security Setup page, click Authentication Server.
Step 2 Use the 802.1X Protocol Version (for EAP authentication) drop-down menu to select the 802.1X-2001 draft
Step 3 Click Apply or OK to apply the setting. The access point reboots.
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
In order to access Cisco Aironet software from the Software Center on Cisco.com, you must now fill out 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 located at the following URL:
Bridge Loop May 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 loop occurs.

This section describes open and resolved caveats for firmware version 8.84.
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 caveats have not been resolved in version 8.84:
•CSCea59101—After a period of time, signal strength test does not display.
After having been in operation for approximately one day, the signal strength test does not display a signal level bar.
Workaround: If possible, perform a warm boot.
•CSCea64630—Workgroup bridge resets to factory defaults.
Condition may occur if workgroup bridge is removed from the network or after losing association with the access point.
There is no workaround for this caveat.
The following caveats were resolved in firmware version 8.84:
•CSCea24527—INET filter setting remains in workgroup bridge configuration when the unit is power cycled.
•CSCdy34205—Client no longer looses its connection every 5 minutes.
•CSCdz43801—Workgroup bridge association table now refreshes the MAC address correctly.
•CSCdz67727—Workgroup bridge no longer loses association to access point, eliminating the need for a reset.
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.
This section describes errors, omissions, and changes in user documentation for workgroup bridges.
Stale Out Time Setting
The workgroup bridge's 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 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 unplug the Ethernet cable from the workgroup bridge and plug it back in, the workgroup bridge removes all devices from its association table and re-learns them regardless of the stale out time setting.
