Configure the paramaters of authentication survivability. The authentication survivability feature requires ClearPass Policy Manager 6.0.2 or later,
and is applicable only when external servers such as RADIUS are configured for the SSID. When enabled, AP authenticates the previously connected clients using
EAP-TLS or MAC authentication even when connectivity to ClearPass Policy Manager is temporarily lost. The authentication survivability feature is not applicable when
a RADIUS server is configured as an internal server. This feature is only applicable for GW.
