Command Usage
◆ WPA2 provides fast roaming for authenticated clients by retaining keys and
other security information in a cache, so that if a client roams away from an
access point and then returns reauthentication is not required.
◆ When a WPA2 client is first authenticated, it receives a Pairwise Master Key
(PMK) that is used to generate other keys for unicast data encryption. This key
and other client information form a Security Association that the access point
names and holds in a cache. The lifetime of this security association can be
configured with this command. When the lifetime expires, the client security
association and keys are deleted from the cache. If the client returns to the
access point, it requires full reauthentication.
