User Guidelines
It is possible to configure the periodic re-authentication timer by sending the
IETF Session-Timeout attribute in the RADIUS Access-Accept. If periodic
re-authentication is not enabled, the session will be terminated and the
802.1X client will need to authenticate again to access the network.
If re-authentication is enabled, the switch will initiate re-authentication and
terminate the session only if the client fails re-authentication.
