This timer is applicable only in the case where the client is authenticated in authentication failure vlan or authentication service unavailable vlan and the RADIUS server provides no session-timeout attribute during authentication. If the switch does receive the session-timeout attribute during authentication, the switch uses that value to set the reauthentication period.
To configure the reauthentication period for network login MAC-based authentication, use the following command:
configure netlogin mac timers reauth-period
