25.1 AAA Overview
This chapter describes how to configure authentication, authorization and accounting settings on the
Switch.
Authentication is the process of determining who a user is and validating access to the Switch. The
Switch can authenticate users who try to log in based on user accounts configured on the Switch itself.
The Switch can also use an external authentication server to authenticate a large number of users.
Authorization is the process of determining what a user is allowed to do. Different user accounts may
have higher or lower privilege levels associated with them. For example, user A may have the right to
create new login accounts on the Switch but user B cannot. The Switch can authorize users based on
user accounts configured on the Switch itself or it can use an external server to authorize a large number
of users.
Accounting is the process of recording what a user is doing. The Switch can use an external server to
track when users log in, log out, and so on. Accounting can also record system related actions such as
boot up and shut down times of the Switch.
The external servers that perform authentication, authorization and accounting functions are known as
AAA servers. The Switch supports RADIUS (Remote Authentication Dial-In User Service, see
) as the external authentication and authorization server.
