Table 21 Configuration items
Item Descri
p
tion
L2TP Group Name Specify the name of the L2TP group.
Peer Tunnel Name
Specify the name of the tunnel peer.
When receiving a tunneling request, an LNS determines whether to grant
the tunneling request by checking whether the name of the LAC (tunnel
peer) matches the one configured.
Local Tunnel Name
Specify the local tunnel name.
By default, the system name of the device is used.
Tunnel Authentication
Enable or disable L2TP tunnel authentication in the group. If you enable
tunnel authentication, you need to set the authentication password.
The tunnel authentication request can be initiated by the LAC or LNS. Once
tunnel authentication is enabled on one end, a tunnel can be established if
tunnel authentication is also enabled on the other end and the passwords
configured on the two ends are the same and not null. If these requirements
cannot be met, the tunnel initiator will tear down the tunnel connection
automatically. If tunnel authentication is disabled on both ends, the tunnel
authentication passwords configured will not take effect.
IMPORTANT:
• HP recommends enabling 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.
• If you modify the tunnel authentication password when the tunnel is
working, you need to tear down the tunnel, so that the modified
authentication password can take effect when the tunnel is
reestablished.
