Managing Users Accounts; Privilege Level - Avaya G250 Administration Manual

Accessing the Avaya G250/G350 Media Gateway
The G250/G350 also uses the 802.1x protocol in conjunction with EAP within EAPOL and over
RADIUS to provide a means for authenticating and authorizing users attached to a LAN port,
and for preventing access to that port in cases where the authentication process fails.

Managing users accounts

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 access the CLI using a modem with dialup PPP. For more information, see
●
Accessing the CLI via modem
When you open Avaya G350 Manager.
●
You can configure various password parameters to enhance your system security. Some
parameters control password length and content, and some control lockout and expiry policies.
When you use Avaya G350 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 open the Avaya G350 Manager or access 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 G250/G350 provides the following three privilege levels:
Read-only. You can use the Read-only privilege level to view configuration parameters.
●
Read-write. You can use the 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 the 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 G250 and Avaya G350 CLI Reference, 03-300437.
