Auto-Command
You can configure the system through the RADIUS server to automatically execute a command when you connect to a specific
line.
The auto-command command is executed when the user is authenticated and before the prompt appears to the user.
● Automatically execute a command.

Privilege Levels
Through the RADIUS server, you can configure a privilege level for the user to enter into when they connect to a session.
This value is configured on the client system.
● Set a privilege level.

Configuration Task List for RADIUS
To authenticate users using RADIUS, you must specify at least one RADIUS server so that the system can communicate with
and configure RADIUS as one of your authentication methods.
The following list includes the configuration tasks for RADIUS.
● Defining a AAA Method List to be Used for RADIUS (mandatory)
● Applying the Method List to Terminal Lines (mandatory except when using default lists)
● Specifying a RADIUS Server Host (mandatory)
● Setting Global Communication Parameters for all RADIUS Server Hosts (optional)
● Monitoring RADIUS (optional)
For a complete listing of supported RADIUS commands, refer to the Security chapter in the Dell Networking OS Command
Reference Guide.
NOTE:
RADIUS authentication and authorization are done in a single step. Hence, authorization cannot be used
independent of authentication. However, if you have configured RADIUS authorization and have not configured
authentication, a message is logged stating this. During authorization, the next method in the list (if present) is used, or if
another method is not present, an error is reported.
To view the configuration, use the show config in LINE mode or the show running-config command in EXEC Privilege
mode.
Defining a AAA Method List to be Used for RADIUS
To configure RADIUS to authenticate or authorize users on the system, create a AAA method list.
Default method lists do not need to be explicitly applied to the line, so they are not mandatory.
To create a method list, use the following commands.
● Enter a text string (up to 16 characters long) as the name of the method list you wish to use with the RADIUS authentication
method.
CONFIGURATION mode
aaa authentication login method-list-name radius
● Create a method list with RADIUS and TACACS+ as authorization methods.
CONFIGURATION mode
aaa authorization exec {method-list-name | default} radius tacacs+
Typical order of methods: RADIUS, TACACS+, Local, None.
If RADIUS denies authorization, the session ends (RADIUS must not be the last method specified).
