www.dell.com | support.dell.com Parameters method-list-name default method ... method4 Enter a text string (up to 16 characters long) as the name of a user-configured method list that can be applied to different lines. Enter the keyword default to specify that the method list specified is the default method for all terminal lines. Enter one of the following methods: • enable - use the password defined by the enable password command in the CONFIGURATION mode. • line - use the password defined by the password command in the LINE mode. • local - use the user name/password defined by the in the local configuration. • none - no authentication. • radius - use the RADIUS server(s) configured with the radius-server host command. • tacacs+ - use the TACACS+ server(s) configured with the tacacs-server host command. (OPTIONAL) Enter up to four additional methods. In the event of a "no response" from the first method, FTOS applies the next configured method (up to four configured methods). Default Command Modes Command History Not configured (that is, no authentication is performed) CONFIGURATION Version 8.3.5.0 Version 7.6.1.0 Version 7.5.1.0 pre-Version 6.2.1.0 Introduced on S55 Introduced for S-Series Introduced for C-Series Introduced on E-Series Usage By default, the locally configured username password will be used. If aaa authentication login Information default is configured, FTOS will use the methods defined by this command for login instead. Methods configured with the aaa authentication login command are evaluated in the order they are configured. If users encounter an error with the first method listed, FTOS applies the next method configured. If users fail the first method listed, no other methods are applied. The only exception is the local method. If the user's name is not listed in the local database, the next method is applied. If the correct user name/password combination are not entered, the user is not allowed access to the switch. Note: If authentication fails using the primary method, FTOS employs the second method (or third method, if necessary) automatically. For example, if the TACACS+ server is reachable, but the server key is invalid, FTOS proceeds to the next authentication method. The TACACS+ is incorrect, but the user is still authenticated by the secondary method. After configuring the aaa authentication login command, configure the login authentication command to enable the authentication scheme on terminal lines. Connections to the SSH server will work with the following login mechanisms: local, radius and tacacs. 916 | Security
