Configuring and Enabling RADIUS
Configuring RADIUS
This section describes how to configure your access point 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, 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 access point.

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 access point through the CLI.
