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.
The access point can store up to 256 entries in the PMKSA cache.
