undo mandatory-lcp

View L2TP group view

Parameter None

Description Use the mandatory-lcpcommand to force an LNS to perform LCP negotiation with users.

Use the undo mandatory-lcpcommand to disable the LCP negotiation.

By default, an LNS does not perform LCP negotiation with users.

When starting a PPP session, a client of NAS-initialized VPN will first negotiate with the network access server (NAS) for LCP parameters. If the negotiation succeeds, the NAS initializes a tunnel and then transfers the negotiated results to the LNS.

Then the LNS verifies whether the client is valid depending on the proxy authentication information. You can use the mandatory-lcpcommand to force the LNS to perform LCP re-negotiation for the client. But the proxy authentication information of the NAS may be neglected. Some PPP clients may not support LCP re-negotiation. In this case, the LCP re-negotiation will fail.

Related command: mandatory-chap.

Example # Perform LCP negotiation by force.

reset l2tp tunnel

Syntax reset l2tp tunnel { remote-name tunnel-id }

View User view

Parameter remote-name: Name of the tunnel at the remote end.

tunnel-id: Local ID of the tunnel, in the range of 1 to 8191.

Description Use the reset l2tp tunnel command to disconnect one or more specified tunnels and all sessions of the tunnels.

Note that:

■A tunnel disconnected by force can be re-established when a client makes a call.

■If you specify a tunnel name, all tunnels with the name, if any, will be disconnected. If no tunnel with the name exists, nothing happens.

■If you specify a tunnel ID, only the tunnel with the ID is disconnected.
