Set local IP address.

address assignment.
Delete the address pool for remote
address assignment.
If you do not assign a value to the pool-number parameter behind the keyword pool
when specifying a global address pool, the system will use the default global address
pool (address pool 0) for assignment. If you do not assign a value to the pool-number
parameter behind the keyword pool when specifying a domain address pool, the
system will use the default domain address pool (domain address pool 0) for
assignment. If domain address pool 0 does not exist, the system selects other domain
address pools one by one.

2.3.12 Setting Username, Password and User Authentication

On LNS side, if mandatory CHAP authentication has been configured, it needs to
configure local registered username and password on LNS side.
LAC performs user authentication to determine whether a user is a valid VPN user by
comparing remote dial-in username and password with usernames and passwords
registered at the local end. If the authentication passes, the VPN user is allowed to
communicate with LNS; if it fails, L2TP will be notified to clear the L2TP connection.
These configurations are optional on LNS side. For more information on how to
configure them, refer to the section "2.2.8 Setting Username, Password and Local
User Authentication".
2.3.13 Disconnecting an L2TP Connection
A connection can be disconnected for one of these reasons: no user is present, fault
occurs on the network, or the administrator requests to do so.
Both LAC side and LNS side can start disconnection. After a tunnel is disconnected, the
control connection and sessions on it are cleared. This tunnel can be set up when a
new user dials in.
These configurations are optional on LNS side.
Perform the following configurations in user view.
