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:

Note
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:
•
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:
•
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.
•
When you finish running a Telnet session to the Access Point you must close the Telnet window to end the session.
•
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.
•
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 the names of clients listed in the Access Point's Association Table.
•
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.
•
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.
•
You cannot set up MAC address filters through the console and Telnet interfaces. Use the browser interface to create and enable MAC address filters.
•
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.
•
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.
