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

Minimum Firmware Version Required on Access Points

Access points with which the bridge associates must contain firmware version 11.05 or later.

Determining the Firmware Version on the Access Point

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 interfaces.

Upgrading to a New Access Point Firmware Release

For instructions on installing access point firmware:


Step 1 Click on the following link to go to the Cisco Aironet documentation home page on CCO:

http://www.cisco.com/univercd/cc/td/doc/product/wireless/index.htm

Step 2 Follow this path to go to the product, document and chapter:
Aironet 350 Series Wireless LAN Products > Cisco Aironet 350 Series Access Points > Cisco Aironet Access Point Software Configuration Guide > Maintaining Firmware > Updating Firmware


Note To upgrade firmware from a file server, you must enter settings on the access point's FTP Server Setup page. Consult the Cisco Aironet Access Point Software Configuration Guide for more information.



New and Changed Information

These release notes incorporate information pertaining to both the 340 series and 350 series bridges. Information applying specifically to the 340 series bridge is identified as such.

New Software Features in Release 8.58_2

There are no new features in this release.

Installation Notes

Verify Mounting Hole Measurement

If you make a photocopy of the mounting template (included in the Mounting Instructions for the Cisco Aironet Access Points, Base Stations, and Workgroup Bridges), 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.

Getting Bug Information on Cisco.com

If you are a Cisco.com registered user, you can use the Cisco TAC Software Bug Toolkit, which consists of three tools (Bug Navigator, Bug Watcher, and Search by Bug ID Number) that help you to identify existing bugs (or caveats) in Cisco software products.

Access the TAC Software Bug Toolkit at http://www.cisco.com/support/bugtools/.

Open Caveats

This section describes known issues for firmware version release 8.58 and earlier.

DHCP ON with Static IP Address Causes Bridge to Lose Association with Access Point

CSCdt50434

If an IP address is statically assigned, DHCP is not automatically disabled when using the web interface. With DHCP enabled, the bridge boots using the assigned IP address as expected. However, the bridge intermittently loses communication with the access point.

The association table on the access point shows a question mark (?) beside the IP address of the bridge. Eventually, the association table shows the IP address as 0.0.0.0.

Workaround: Disable DHCP on the bridge.

SMIC Errors Compiling Cisco Aironet MIBs

CSCdr93580

When using SMIC (the compiler Cisco uses to test MIBs), the Cisco Aironet MIB does not compile without errors. SMIC displays a message indicating that "0" cannot be used as an enumerated value and prevents the MIB from being posted on CCO.

Workaround: The TAC will provide the MIB by email on request.
