• Monitoring RADIUS (optional)
For a complete listing of all Dell Networking OS commands related to RADIUS, 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 congured RADIUS authorization and have not congured 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 conguration, use the show config in LINE mode or the show running-config command in EXEC Privilege mode.
Dening a AAA Method List to be Used for RADIUS
To congure 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 specied).
Applying the Method List to Terminal Lines
To enable RADIUS AAA login authentication for a method list, apply it to a terminal line.
To congure a terminal line for RADIUS authentication and authorization, use the following commands.
• Enter LINE mode.
CONFIGURATION mode
line {aux 0 | console 0 | vty number [end-number]}
• Enable AAA login authentication for the specied RADIUS method list.
LINE mode
login authentication {method-list-name | default}
This procedure is mandatory if you are not using default lists.
• To use the method list.
CONFIGURATION mode
authorization exec methodlist
