XV. Disconnecting a Tunnel Forcibly (Optional)
Tunnel clearing process occurs:
When there is no user.
When network fails.
When the administrator requires disconnecting tunnel.
Either LAC side or LNS side can send request for clearing tunnel initiatively. The side
that receives clearing request must:
Send acknowledgement (ACK) information;
Wait for a period of time before clearing tunnel.
In this case, the receiver can correctly receive the resent clearing request from the
peer end if the ACK information is lost.
After the tunnel is disconnected forcibly, all control connection and session
connection in the tunnel will also be cleared. New tunnels can be re-created when
new users dial up.
Do as follows in user view.
