Interface Configuration

Note:
If the authentication mode is set to none or password, the command level that a user
can access is determined by the level of the user interface where the user logs in. If the
authentication is set to local (username and password are required), the command
level that the user can access is determined by the level of the user.
2.3 Telnet Terminal Service Configuration
2.3.1 Telnet Service Type
Telnet is an application layer protocol in the TCP/IP protocol suite. It provides remote
logon and virtual terminal services. Both Telnet server and client services are available
with the XE IP PBX.

When working as a Telnet server, the XE IP PBX needs to authenticate the Telnet client.
The authentication configuration must be done in the VTY user interface.

In system view, you can enter the view of a user interface by using its name and relative
