Configuration of L2TP

VIII. Force to disconnect tunnel

When the user number is 0, or faults occur to the network, or operators take the initiative to require disconnecting the channel, the tunnel will be cleared. LAC or LNS can originate the request to clear the tunnel. The end receiving the request to clear should transmit acknowledgement information (ACK) and wait for some time before clearing the tunnel so that the request transmitted again from opposite end can be properly received when ACK is lost. After forced channel disconnection, all control connections and session connections on the channel will also be cleared.

After channel disconnection, when new users dial in, the channel can be established again. Perform the following task in privileged user mode.
