Chapter 5 Administering the Bridge Controlling Bridge Access with TACACS+ Default TACACS+ Configuration TACACS+ and AAA are disabled by default. To prevent a lapse in security, you cannot configure TACACS+ through a network management application.When enabled, TACACS+ can authenticate administrators accessing the bridge through the CLI. Configuring TACACS+ Login Authentication To configure AAA authentication, you define a named list of authentication methods and then apply that list to various interfaces. The method list defines the types of authentication to be performed and the sequence in which they are performed; it must be applied to a specific interface before any of the defined authentication methods are performed. The only exception is the default method list (which, by coincidence, is named default). The default method list is automatically applied to all interfaces except those that have a named method list explicitly defined. A defined method list overrides the default method list. A method list describes the sequence and authentication methods to be queried to authenticate a user. You can designate one or more security protocols to be used for authentication, thus ensuring a backup system for authentication in case the initial method fails. The software uses the first method listed to authenticate users; if that method fails, the software selects the next authentication method in the method list. This process continues until there is successful communication with a listed authentication method or until all defined methods are exhausted. If authentication fails at any point in this cycle-meaning that the security server or local username database responds by denying the user access-the authentication process stops, and no other authentication methods are attempted. Beginning in privileged EXEC mode, follow these steps to configure login authentication. This procedure is required.
