CHAPTER 24 AAA 24.1 Overview This chapter describes how to configure authentication and authorization settings on the Switch. The external servers that perform authentication and authorization functions are known as AAA servers. The Switch supports RADIUS (Remote Authentication Dial-In User Service, see Section on page 183) and TACACS+ (Terminal Access Controller Access-Control System Plus, see Section on page 183) as external authentication and authorization servers. Figure 115 AAA Server Client AAA Server 24.1.1 What You Can Do • Use the AAA screen (Section 24.2 on page 183) to enable authentication and authorization or both of them on the Switch. • use the RADIUS Server Setup screen (Section 24.3 on page 183) to configure your RADIUS server settings. • Use the TACACS+ Server Setup screen (Section 24.4 on page 186) to configure your TACACS+ authentication settings. • Use the AAA Setup screen (Section 24.5 on page 188) to specify the methods used to authenticate users accessing the Switch and specify which database the Switch should use first. 24.1.2 What You Need to Know 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.

Overview
This chapter describes how to configure authentication and authorization settings on the Switch.
The external servers that perform authentication and authorization functions are known as AAA
servers. The Switch supports RADIUS (Remote Authentication Dial-In User Service, see
Section
on
page 183
) and TACACS+ (Terminal Access Controller Access-Control System Plus, see
Section
on
page 183
) as external authentication and authorization
servers.
Figure 115
AAA Server
24.1.1
What You Can Do
Use the
AAA
screen (
Section 24.2 on page 183
) to enable authentication and authorization or
both of them on the Switch.
use the
RADIUS Server Setup
screen (
Section 24.3 on page 183
) to configure your RADIUS
server settings.
Use the
TACACS+ Server Setup
screen (
Section 24.4 on page 186
) to configure your TACACS+
authentication settings.
Use the
AAA Setup
screen (
Section 24.5 on page 188
) to specify the methods used to
authenticate users accessing the Switch and specify which database the Switch should use first.
24.1.2
What You Need to Know
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.
