Group Key Update
Timer
The Group Ke y Upd a te Time r is the rate at which the AP (if using WPA- PSK/ WPA2- PSK key
management) or RADIUS server (if using WPA/ WPA2 key management) sends a new group
key out to all clients. The re-keying process is the WPA/WPA2 equivalent of automatically
changing the WEP key for an AP and all stations in a WLAN on a periodic basis. Setting of
the Group Ke y Upd a te Tim e r is also supported in WPA- PSK/ WPA2- PSK mode.
PMK Cache Period This field is available only when you select WPA 2.
Specify how often wireless clients have to resend usernames and passwords in order to
stay connected. Enter a time interval between 10 and 999999 minutes.
Note: If wireless client authentication is done using a RADIUS server, the
reauthentication timer on the RADIUS server has priority.
