Administering the Switch
The ACCEPT or REJECT response is bundled with additional data that is used for privileged EXEC or
network authorization. Users must first successfully complete RADIUS authentication before
proceeding to RADIUS authorization, if it is enabled. The additional data included with the ACCEPT or
REJECT packets includes these items:

Configuring RADIUS
This section describes how to configure your switch to support RADIUS. At a minimum, you must
identify the host or hosts that run the RADIUS server software and define the method lists for RADIUS
authentication. You can optionally define method lists for RADIUS authorization and accounting.
A method list defines the sequence and methods to be used to authenticate, to authorize, or to keep
accounts on a user. You can use method lists to designate one or more security protocols to be used (such
as TACACS+ or local username lookup), thus ensuring a backup system if the initial method fails. The
software uses the first method listed to authenticate, to authorize, or to keep accounts on users; if that
method does not respond, the software selects the next method in the list. This process continues until
there is successful communication with a listed method or the method list is exhausted.
You should have access to and should configure a RADIUS server before configuring RADIUS features
on your switch.

Default RADIUS Configuration
RADIUS and AAA are disabled by default.
To prevent a lapse in security, you cannot configure RADIUS through a network management
application. When enabled, RADIUS can authenticate users accessing the switch through the CLI.
