Configuring the keep-online feature

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.

In a fast-recovery network, you can use the keep-online feature to prevent MAC authentication users from coming online and going offline frequently.
