Overview
802.1X reauthentication tracks the connection status of online users and updates the authorization attributes assigned by the server. The attributes include the ACL and VLAN.
The following methods are available for 802.1X reauthentication:
Manual reauthentication—Allows you to manually reauthenticate all online 802.1X users on a port.
Periodic reauthentication—Reauthenticates online users at a user-configurable reauthentication interval.
By default, the device logs off online 802.1X users if no server is reachable for 802.1X reauthentication. The keep-online feature keeps authenticated 802.1X users online when no server is reachable for 802.1X reauthentication, either manually or periodically.
