Accessing the Avaya G250/G350 Media Gateway

CLI Overview

The CLI is a textual command prompt interface that you can use to configure the Avaya G250/
G350 Media Gateway and media modules. You can access the CLI with any of the following:
Telnet through the network
●
A console device
●
Telnet through dialup:
●
Telnet through a serial modem
●
Telnet through a USB modem (G350 only)
●
Telnet through a USB modem via the S8300
●
Log in to the CLI with a username and password that your system administrator provides. If
your network has a RADIUS server, you can use RADIUS authentication. For more information,
see Managing login permissions
Note:
You can disconnect a telnet session by typing <Ctrl>+]. This is particularly useful
Note:
if the normal telnet logout does not work.

CLI contexts

The CLI is divided into various contexts from which sets of related commands can be entered.
Contexts are nested in a hierarchy, with each context accessible from another context, called
the parent context. The top level of the CLI tree is called the general context. Each command
has a context in which the command must be used. You can only use a command in its proper
context.
For example, in order to configure the Loopback interface, you must first enter the Loopback
interface context from general context. Enter the Loopback interface context using the
interface loopback 1 command. Once you are in the Loopback interface context, you can
enter Loopback interface commands.

CLI help

You can display a list of commands for the context you are in by typing help or ?. The help
command displays a list of all CLI commands that you can use within the current context, with a
short explanation of each command.
If you type help or ? before or after the first word or words of a command, the CLI displays a
list of all commands in the current context that begin with this word or words. For example, to
display a list of IP commands available in general context, type help ip, ip help, ? ip, or
ip ?.
