For more information, see Accessing the CLI on page 27.●When you connect to the console port modem with dialup PPP. For more information, seeAccessing CLI via modem on page 30.● When you open Avaya G350 Manager.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 ausername and password. A RADIUS server provides centralized authentication service formany devices on a network. For more information, see RADIUS authentication on page 40.Privilege levelWhen you start to use Avaya G350 Manager or the CLI, you must enter a username. Theusername that you enter sets your privilege level. The commands that are available to youduring the session depend on your privilege level. If you use RADIUS authentication, theRADIUS server sets your privilege level.The G350 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 configurationparameters except those related to security. For example, you cannot change a passwordwith Read-write privilege level.● Admin — You can use Admin privilege level to view and change all configurationparameters, including parameters related to security. Use Admin privilege level only whenyou need to change configuration that is related to security, such as adding new useraccounts and setting the device policy manager source.The default username has Admin privilege level. For security reasons, the networkadministrator usually changes the password of the default username. For more informationabout privilege levels, see Avaya G350 Media Gateway CLI Reference, 555-245-202.Configuring usernamesTo create a username, use the username command. To remove a username, use the nousername command. To change the password or the privilege level for a username, removethe username and add it again.
