Overview

Periodic MAC reauthentication reauthenticates online MAC authentication users at a user-configurable reauthentication interval. The reauthentication feature tracks the connection status of online users and updates the authorization attributes assigned by the server. The attributes include the ACL and VLAN.

By default, the device logs off online MAC authentication users if no server is reachable for MAC reauthentication. The keep-online feature keeps authenticated MAC authentication users online when no server is reachable for MAC reauthentication.
