2) Basic configurations of the VTY user interface
The basic configurations of the VTY user interface include:
z
Setting the authentication mode. Three types of authentication modes are
available: AAA, local authentication, and password. You may set it to none. By
default, password authentication applies.
z
Setting the password for password authentication. If you choose a password
authentication mode, you need to set the password.
z
Setting user level. The commands that you can access are decided by the level of
the user interface where you log in or by the user level. If you are not assigned a
user level or you are to be authenticated by password, then the user interface level
applies. If you have a user level and is to be authenticated through AAA or local
authentication, then the assigned user level applies.
Perform the following configuration in VTY user interface view.

3) Advanced configurations of the VTY user interface
You may perform the following tasks as needed:
z
Enabling/disabling the terminal service. By default, the XE IP PBX has enabled all
the terminal services, but you can disable them as needed.
z
Configuring the auto-execute command command. It makes the XE IP PBX
automatically execute some commands when you telnet to it, for example,
telneting to another service server.
z
Setting the idle-timeout timer. This command has two purposes: one is to prevent
others from operating on the terminal when the terminal is unattended for a long
time, and the other is to release VTY resources when the terminal is idle for a long
time.
z
Specifying the protocols supported by the current user interface. By default, the
XE IP PBX supports Telnet. You may disable some protocols as needed.
z
Setting the size of the history command buffer. By default, each Telnet terminal
can store up to 10 history commands. You may change it as needed.
