Table 161 Configuration items
Item Description
L2TP Group Name Specify the name of the L2TP group.
Peer Tunnel Name Specify the peer name of the tunnel.
Local Tunnel Name Specify the local name of the tunnel.
Tunnel Authentication Enable or disable L2TP tunnel authentication in the group. If you
enable tunnel authentication, you need to set the authentication
password.
Either the LAC or LNS end can initiate a tunnel authentication
request. If tunnel authentication is enabled on one end, the tunnel
can be established successfully only if the other end is also
enabled with tunnel authentication, and the two ends are
configured with the same authentication passwords. If tunnel
authentication is disabled on both ends, authentication passwords
do not take effect.
IMPORTANT:
• Typically, you must enable tunnel authentication on both ends
of the tunnel for security. You can disable tunnel authentication
if you want to test the network connectivity or let the local end
receive connections initiated by unknown peers.
• To change the tunnel authentication password, do so after
tearing down the tunnel. Otherwise, your change does not take
effect.
