Introduction

This document describes requirements, installation procedures, and caveats for Cisco Aironet Access Point firmware version 11.01.

System Requirements

You must have a Cisco Aironet 340 or 350 series Access Point to install firmware version 11.01.

Version Supported

Your Access Point must be running firmware version 10.x or later to install firmware version 11.01.

Upgrading to a New Firmware Release

Determining the Firmware Version

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.

Upgrade Procedure

For instructions on installing Access Point firmware:

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

2. Use the following link 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 "Updating from a File Server" section on page 5-5 in the Cisco Aironet Access Point Software Configuration Guide for more information.


Limitations and Restrictions

MIB File Compatible with Firmware Version 11.0x

The Aironet Access Point MIB file (AWCVX-MIB) is supported by Access Point firmware versions 11.00 and later. Earlier versions of firmware do not support this MIB.

Caveats

Getting Bug Information on Cisco.com

If you are a Cisco 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 identify existing bugs (or caveats) in Cisco software products.

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

Resolved Caveats

The following caveats have been resolved in firmware version 11.01:

340 Series Access Point reports polls from disassociated client device (CSCdt09173).

Client devices using Fast PSP mode and LEAP shut down but continue to send polls to the Access Point to which they were associated. The Access Point repeatedly reports that it is receiving polls from a client device that is not associated. To avoid this problem, do not set up client devices to use both Fast PSP mode and LEAP.

Open Caveats

The following caveats have not been resolved for firmware version 11.01:

Must use Aironet extensions in repeater mode.

You must enable Aironet extensions on the AP Radio Advanced page when you set up the Access Point as a repeater. If you disable Aironet extensions when in repeater mode, connect a serial cable to the Access Point and enable Aironet extensions with the console interface.

Difficult to end Telnet session (CSCav00156).

When you finish running a Telnet session to the Access Point you must close the Telnet window to end the session.

Network response times might be slow on networks with thousands of client devices (CSCdr95686).

On large, flat networks with thousands of client devices, the Access Point might respond slowly to network traffic. Segmenting the network into subnets can improve Access Point performance.

Must restart unit twice to enable standby mode (CSCds36123).

When you set up an Access Point as a standby unit, follow the instructions on page 7-5 in the Cisco Aironet Access Point Software Configuration Guide. When you complete the instruction steps, return to the Hot Standby page and click Start Hot Standby Mode again. When the unit restarts it is in standby mode.

Corrupt characters sometimes appear in client names in the Association Table (CSCds56664).

Corrupt characters sometimes appear in the names of clients listed in the Access Point's Association Table.

Access Point does not support client devices using LEAP with WEP keys of different lengths (CSCds61358).

The length of the transmit WEP key set on the Access Point determines the length of the session keys used by LEAP clients. For example, if the transmit key on the Access Point is a 128-bit key, all LEAP clients associated to the Access Point must use 128-bit WEP keys.

Inoperable link in console and Telnet interfaces (CSCds71375 and CSCds71448).

In the console and Telnet (CLI) interfaces the link to the FTP Server Setup page is inoperable on the Update All Firmware From File Server and Selectively Update Firmware From File Server pages.

No address filtering pages in console and Telnet interfaces (CSCdt02327).

You cannot set up MAC address filters through the console and Telnet interfaces. Use the browser interface to create and enable MAC address filters.

User management passwords corrupted when updating firmware from version 10.12 to 11.0x (CSCdt07632).

When upgrading Access Point firmware from version 10.12 to 11.0x with user information in the user manager database, the user passwords are corrupted during the upgrade. This problem also occurs if the users are added to the user manager database in version 10.12, the firmware is upgraded to version 10.13, and then upgraded to version 11.0x. If the users and passwords are created in version 10.13, the passwords are not corrupted during the upgrade. To avoid being locked out of the Access Point, disable the user manager before upgrading from version 10.12 to 11.0x. After the upgrade, re-enter the user passwords and enable user manager.

Broken help links on Access Point and Bridge CD (CSCdt12716).

If you change the default help root URL on a 350 series Access Point's Web Server Setup page to use the help files on the Cisco Aironet Access Point and Bridge CD, the help buttons on the AP Radio Port, AP Radio Advanced, AP Radio Hardware, and AP Radio Identification pages will not work. To use the most up-to-date online help, leave the default help root URL at its default setting.

Troubleshooting
