Debugging

To determine if the universal client has associated to the access point, the user can issue the 'show dot11 association all' command for a detailed output of which access point it was associating to and how it has associated to the access point.

The "show dot11 association" command will have the following output:

Caveats

When the Cisco dot11radio is in the universal client mode and associates to a 3rd party access point, there are some additional caveats. The first is on the "show dot11 association" output. The "Device" area shows a result of "unknown" when associated to a 3rd party access point (non-Cisco). In the example below, a Cisco 876W universal client is associated to a Symbol 4131 Access Point. The "Software Version" and "Name" fields also result in "NONE". This is because the Cisco Aironet messages between Cisco devices carry this information and not between 3rd party and Cisco devices.

Example:

c876#sh dot11 assoc
