Usage Guidelines
The display l2tp session command displays the number of L2TP sessions that are established on the current device, local session ID and remote session ID of each session, and the corresponding local tunnel ID. After an L2TP tunnel is established, you can run the display l2tp session command to view whether local tunnel IDs of some sessions belong to the L2TP tunnel, and how many these sessions are present.In the scenario where 1:1 inter-board backup is configured on the LNS, run the display l2tp session lns slot backup command to check session entries in backup mode.
