AAA Server
42.1 Overview
You can use a AAA (Authentication, Authorization, Accounting) server to provide access control to
your network. The AAA server can be a RADIUS server. Use the
AAA Server screens to create and
manage objects that contain settings for using AAA servers. You use AAA server objects in
configuring ext-group-user user objects and authentication method objects (see
Chapter 43 on
page 464 ).
42.1.1 RADIUS Server
RADIUS (Remote Authentication Dial-In User Service) authentication is a popular protocol used to
authenticate users by means of an external server instead of (or in addition to) an internal device
user database that is limited to the memory capacity of the device. In essence, RADIUS
authentication allows you to validate a large number of users from a central location.

42.1.2 What You Can Do in this Chapter
Use the Configuration > Object > AAA Server > RADIUS screen ( Section 42.2 on page 460 ) to
configure the default external RADIUS server to use for user authentication.
