which is 8.4hours, each client will have to pass re-authentication.
The pairwise master key lifetime indicates the time in seconds
that the pairwise key (the key used for encrypting unicast traffic)
is valid in the WBS-2400 cache. PML default value is 43200
seconds or 12 hours.
The intervals in which re-authentication shall occur can be
specified on the RADIUS server. Alternatively, default values for
re-authentication intervals are specified as WBS-2400 parameters
(the first two fields on this page).
For WPA SSID, the administrator determines if and how often re-
keying of broadcast keys occurs.
