Introduction

Defect caveat CSCec11918 identifies and describes an erroneous behavior that occurs when you upgrade the software on a Cisco Aironet 350 Series Workgroup Bridge. It is less likely to occur when you change the workgroup bridge configuration. The failure mode associated with this defect is that after the software upgrade is attempted, the workgroup bridge does not accept the upgrade.

Version 8.85 resolves this problem when it is installed immediately after running the upgrade patch.


Note The upgrade patch and version 8.85 are intended for use only if a firmware upgrade is required. Cisco recommends not running the patch or upgrading the firmware unless it is absolutely necessary to do so.


System Requirements

You must have a Cisco Aironet 350 Series Workgroup Bridge to install the upgrade patch and firmware version 8.85.

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.

Upgrade Procedure

For instructions on installing access point and bridge firmware:


Step 1 Follow this link to the Software Center on Cisco.com and download firmware version 8.84:

Installation Notes

The upgrade patch and firmware must be installed concurrently. Do not begin the process unless you intend to complete it in one operation.

Running the Upgrade Patch

The procedure below lists the steps to install the patch using the Windows command prompt. If you prefer, you can run the patch from the Windows task bar by selecting Start > Run. Make sure you include the workgroup bridge's IP address following the command in the Run field. If you use this method to run the patch, the window may close too fast and prevent you from seeing all the installation status messages the patch displays.

Follow these steps to install the upgrade patch from the Windows command prompt:


Step 1 Identify a Windows-based PC on the same network segment as the workgroup bridge you intend to upgrade.

Step 2 Identify the IP address of the workgroup bridge you intend to upgrade.


Note If you do not know the workgroup bridge's IP address, your system administrator can provide it for you or you can use the IP Setup Utility (IPSU) to retrieve it. IPSU is available on Cisco.com at the following URL:
http://www.cisco.com/pcgi-bin/tablebuild.pl/aironet_350_wgb



Note If you use IPSU, you will also need the workgroup bridge's MAC address. The MAC address is located on the label on the back of the workgroup bridge.


Step 3 On your Windows-based PC, open a command prompt window.

Step 4 Change to the drive and directory where you downloaded the upgrade patch.

Step 5 Run the patch by entering the following command:

upgrade_patch <IP_addr>

(Where <IP_addr> is the IP address of the workgroup bridge you intend to upgrade).

Step 6 Press Enter. The following message appears:

This utility is intended to be used on the Cisco Aironet 350 Workgroup Bridge to prepare 
it for software upgrade. 

PLEASE DO NOT REMOVE POWER IN BETWEEN USING THIS UTILITY AND PERFORMING THE SOFTWARE 
UPGRADE!!!!

Please proceed with caution, this upgrade process should only be performed if absolutely 
needed.

Would you like to proceed? <y/n>y

Step 7 Press Enter to install the upgrade patch utility.

The installation process begins. The following status messages appear as they occur:

Step 1 complete
Step 2 complete
Step 3 complete
Step 4 complete
Step 5 complete
Step 6 complete
Step 7 complete
Step 8 complete

Your Cisco Aironet 350 Workgroup Bridge is ready to be upgraded in the usual manner.

PLEASE DO NOT REMOVE POWER IN BETWEEN USING THIS UTILITY AND PERFORMING THE SOFTWARE 
UPGRADE!!!!

Note Do not restart the workgroup bridge or remove power. Go immediately to Step 8.


Step 8 Open a Telnet session or browse to the workgroup bridge and install version 8.85.


If the patch installation was unsuccessful, the following message appears:

final status unsuccessful

Your Cisco Aironet 350 Workgroup Bridge is NOT ready to be upgraded.

Before contacting Cisco, verify that you are able to communicate with the workgroup bridge by opening a Telnet or browser session. If you are able to establish communications, try running the patch again. If you are unable to establish communications, check the troubleshooting chapter of the Cisco Aironet 350 Series Workgroup Bridge Hardware Installation Guide. The guide is available on Cisco.com at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/wireless/airo_350/350wgb/350hig/wgbch4.htm

Important Notes

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.

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.
