To enable or disable the network login session refresh, use the following commands:
enable netlogin session-refresh {refresh_minutes}
disable netlogin session-refresh
Where minutes ranges from 1 - 255. The default setting is 3 minutes. The commands enable netlogin session-refresh and configure netlogin session-refresh make the logout window refresh itself at every configured time interval. Session refresh is enabled by default. When you configure the network login session refresh for the logout window, ensure that the FDB (forwarding database) aging timer is greater than the network login session refresh timer.
Note
If an attempt is made to authenticate the client in a non-existent VLAN (Virtual LAN), and the move fail action setting is authenticate, then the client is successfully authenticated in the port‘s original VLAN, but subsequent session refreshes fail and cause the client to become unauthenticated.
