Maintaining L2TP

Maintaining L2TP

L2TP maintenance can be performed by monitoring L2TP and clearing L2TP tunnels.


By monitoring L2TP, you can know the L2TP operating status. You can run the associated command to delete an L2TP tunnel only when there is no user, a network fault occurs, or a device requests an L2TP tunnel to be torn down. In routine maintenance, you can run the following commands in any view to check the L2TP operation. To clear an L2TP tunnel, run the reset command. An L2TP tunnel cannot be restored after it is cleared. Exercise caution when running the command.


  1. Run the reset l2tp tunnel { lac | lns slot slot-id } { tunnel-item tunnel-id | tunnel-name remote-name } command to forcibly clear an L2TP tunnel.

    After the l2tp tunnel auto-reset enable command is configured, an LAC or LNS automatically removes an L2TP tunnel if no session control message is received from the remote end after 127 ICRQ or ICRP messages are sent within 10 minutes. You do not need to run the reset l2tp tunnel command to forcibly remove an L2TP tunnel.
