how the AP removes the unresponsive wireless client from the association table
I'd like to know the details regarding how the Cisco autonomous AP(not lightweight) removes the unresponsive wireless client from the association table. Is there a keepalive message exchanged between the client and the AP? If yes, how often is the message exchange?
I noticed on the autonomous AP, there is a "packet retries xxx drop-packet" command. If the maximum retry is reached, the AP disassociates the client because the client did not respond to max keep-alive messages sent by the AP. In this case, what is the time interval of this retry packet?
If somebody can point a link, that would be great. Thanks.

The User Idle Timeout: When a user is idle without any communication with the LAP for the amount of time set as User Idle Timeout, the client is deauthenticated by the WLC. The client has to reauthenticate and reassociate to the WLC. It is used in situations where a client can drop out from its associated LAP without notifying the LAP. This can occur if the battery goes dead on the client or the client associates move away.
