Dell Command Line Reference Guide for the S4048–ON System


aaa authentication enable

Configure AAA Authentication method lists for user access to EXEC privilege mode (the “Enable” access).

aaa authentication enable {default | method-list-name} method [... method2]

To return to the default setting, use the no aaa authentication enable {default | method-list-name} method [... method2] command.

Enter the keyword default then the authentication methods to use as the default sequence of methods for the Enable login. The default is default enable.
Enter a text string (up to 16 characters long) to name the list of enabled authentication methods activated at login.
Enter one of the following methods:
  • enable: use the password the enable password command defines in CONFIGURATION mode.
  • line: use the password the password command defines in LINE mode.
  • none: no authentication.
  • radius: use the RADIUS servers configured with the radius-server host command.
  • tacacs+: use the TACACS+ server(s) configured with the tacacs-server host command.
... method2
(OPTIONAL) In the event of a “no response” from the first method, Dell EMC Networking OS applies the next configured method.
Use the enable password.

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.
