AAA is a framework for authentication, authorization, and accounting in a Cisco environment. To perform these processes, a Cisco device uses a method list, along with other configuration tasks to designate the server and protocol. At this point, you should have a basic understanding of what the AAA framework is, what it provides in your network, and the most basic process of configuration. Chapter 2, "TACACS+ and RADIUS" will discuss the TACACS+ and RADIUS protocols and how they communicate between the AAA server and the AAA client. In Chapter 3, you will configure AAA on a Cisco router and discuss some of the implications that might come along with these configurations. |
