Accessing the Avaya G450 Media Gateway

Managing users and passwords

You must provide a username and password when you perform any of the following actions:
When you access the CLI. For more information, see
●
When you connect a modem with dialup PPP. For more information, see
●
CLI via modem
When you open Avaya G450 Managerr.
●
When you use Avaya G450 Manager or the CLI, your username determines your privilege level.
The commands that are available to you during the session depend on your privilege level.
If your network has a RADIUS server, you can use RADIUS authentication instead of a
username and password. A RADIUS server provides centralized authentication service for
many devices on a network.

Privilege level

When you start to use Avaya G450 Manager or the CLI, you must enter a username. The
username that you enter sets your privilege level. The commands that are available to you
during the session depend on your privilege level. If you use RADIUS authentication, the
RADIUS server sets your privilege level.
The G450 provides the following three privilege levels:
Read-only. You can use Read-only privilege level to view configuration parameters.
●
Read-write.You can use Read-write privilege level to view and change all configuration
●
parameters except those related to security. For example, you cannot change a password
with Read-write privilege level.
Admin.You can use Admin privilege level to view and change all configuration parameters,
●
including parameters related to security. Use Admin privilege level only when you need to
change configuration that is related to security, such as adding new user accounts and
setting the device policy manager source.
The default username has Admin privilege level. For security reasons, the network
administrator usually changes the password of the default username. For more information
about privilege levels, see Avaya G450 CLI Reference, 03-602056.

Configuring usernames

To create a username, use the username command. To remove a username, use the no
username command. To change the password or the privilege level for a username, remove
the username and add it again. You need an Admin privilege level to use the username and no
username commands.
