Dell S3100 EMC Command Line Reference Guide for the Series 9.14.2.6 - Page 1313

Version 7.5.1.0 6.2.1.0 Description Introduced on the C-Series. Introduced on the E-Series. Usage Information By default, the Enable password is used. If you configure aaa authentication enable default, Dell EMC Networking OS uses the methods defined for Enable access instead. Methods configured with the aaa authentication enable command are evaluated in the order they are configured. If authentication fails using the primary method, Dell EMC Networking OS employs the second method (or third method, if necessary) automatically. The fallback to the second method would happen only if the authentication failure is due to a non-reachable server or invalid TACACS server key. The fallback would not occur if the authentication failure is due to invalid credentials. For example, if the TACACS+ server is reachable, but the server key is invalid, Dell EMC Networking OS proceeds to the next authentication method. Related Commands • enable password - changes the password for the enable command. • login authentication - enables AAA login authentication on the terminal lines. • password - creates a password. • radius-server host - specifies a RADIUS server host. • tacacs-server host - specifies a TACACS+ server host. aaa authentication login Configure AAA Authentication method lists for user access to EXEC mode (Enable log-in). Syntax Parameters aaa authentication login {method-list-name | default} method [... method4] To return to the default setting, use the no aaa authentication login {method-list-name | default} command. method-list-name 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. default method 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 the enable password command defines in CONFIGURATION mode. Not available if role-only is in use. • line: use the password the password command defines in LINE mode. Not available if role-only is in use. • local: use the password for the userid contained in the local password database. • none: no authentication. Not available if role-only is in use. • radius: use the RADIUS servers configured with the radius-server host command. • tacacs+: use the TACACS+ servers configured with the tacacs-server host command. ... method4 (OPTIONAL) Enter up to four additional methods. In the event of a "no response" from the first method, the system applies the next configured method (up to four configured methods). Defaults Not configured (that is, no authentication is performed). Command Modes CONFIGURATION Command History This guide is platform-specific.
