• The ias method is a special method that is only used for 802.1X. It uses an internal database (separate from the local user database) that acts like an 802.1X authentication server. This method never returns an error. It will always pass or deny a user. • The line method uses the password for the access line on which the user is accessing the switch. If there is no line password defined for the access line, then the line method will return an error. • The local method uses the local user database. If the user password does not match, then access is denied. This method returns an error if the user name is not present in the local user database. • The none method does not perform any service, but instead always returns a result as if the service had succeeded. This method never returns an error. • The radius and tacacs methods communicate with servers running the RADIUS and TACACS+ protocols, respectively. These methods can return an error if the switch is unable to contact the server. Access Lines There are five access lines: console, telnet, SSH, HTTP, and HTTPS. HTTP and HTTPS are not configured using AAA method lists. Instead, the authentication list for HTTP and HTTPS is configured directly (authorization and accounting are not supported). The default method lists for both the HTTP and HTTPS access lines consist of only the local method. Each of the other access lines may be assigned method lists independently for the AAA services. Authentication Authentication is the process of validating a user's identity. During the authentication process, only identity validation is done. There is no determination made of which switch services the user is allowed to access. This is true even when RADIUS is used for authentication; RADIUS cannot perform separate transactions for authentication and authorization. However, the RADIUS server can provide attributes during the authentication process that are used in the authorization process. There are three types of authentication: Configuring Authentication, Authorization, and Accounting 181
