Charpter 43. AAA Commands AAA stands for authentication, authorization and accounting. This feature is used to authenticate users trying to log in to the switch or trying to access the administrative level privilege. ■ Applicable Access Application The authentication can be applied on the following access applications: Telnet, SSH and HTTP. ■ Authentication Method List A method list describes the authentication methods and their sequence to authenticate a user. The switch supports Login List for users to gain access to the switch, and Enable List for normal users to gain administrative privileges. ■ RADIUS/TACACS+ Server User can configure the RADIUS/TACACS+ servers for the connection between the switch and the server. ■ Server Group User can define the authentication server group with up to several servers running the same secure protocols, either RADIUS or TACACS+. Users can set these servers in a preferable order, which is called the server group list. When a user tries to access the switch, the switch will ask the first server in the server group list for authentication. If no response is received, the second server will be queried, and so on. 43.1 tacacas-server host Description The tacacs-server host command is used to configure a new TACACS+ server.
