System Configuration
Default VLAN ID – The VLAN ID assigned to wireless clients associated to the VAP
interface that are not assigned to a specific VLAN by RADIUS server configuration.
(Default: 1)
Closed System – When enabled, the VAP interface does not include its SSID in
beacon messages. Nor does it respond to probe requests from clients that do not
include a fixed SSID. (Default: Disable)
Authentication Timeout Interval – The time within which the client should finish
authentication before authentication times out. (Range: 5-60 minutes; Default: 60
minutes)
Association Timeout Interval – The idle time interval (when no frames are sent) after
which a client is disassociated from the VAP interface. (Range: 5-60 minutes;
Default: 30 minutes)
WPA2 PMKSA Life Time – WPA2 provides fast roaming for authenticated clients by
retaining keys and other security settings in a cache for each VAP. In this way, when
clients roam back into a VAP they had previously been using, re-authentication is
not required. When a WPA2 client is first authenticated, it receives a Pairwise
Master Key (PMK) that is used to generate the other keys used for unicast data
encryption. This key and other client information form a client Security Association
(SA) that the VAP holds in a cache. When the lifetime expires, the security
association and keys are deleted from the cache. If the client returns to an access
point after the association has been deleted, it will require full re-authentication.
(Range: 1-1440 minutes; Default: 720 minutes)
