show l2tun session
135
Cisco IOS Releases 12.0(29)S and 12.2(25)S
Usage Guidelines When you use the show l2tun session command to display information about current L2TPv3 sessions
on the router, you can filter the output as follows:
• To filter the output to include only L2TPv3 sessions set up for a specific IP address, enter ip-addr
ip-address in the command.
• To filter the output to include only the L2TPv3 session that matches the specified remote IP address
and virtual circuit identifier, enter ip-addr ip-address vcid number in the command.
• To filter the output to include only L2TPv3 sessions set up for a specific IP address, enter vcid
number in the command.
Examples The following example shows how to display detailed information about all current L2TPv3 sessions:
