Description: The number of currently active LAN to LAN sessions.
What is crasL2LNumSessions?
This object reports the number of currently active LAN-to-LAN (site-to-site) VPN tunnels on the device, distinct from the individual remote-user sessions tracked elsewhere in this MIB. An admin monitoring a hub site with multiple branch-office tunnels can use this to confirm all expected site-to-site tunnels are up, since a drop in this count signals a branch tunnel has gone down. A hub with 12 branch offices would normally show this steady at 12, and any dip below that warrants investigating which site lost connectivity.
