Dell Z9000 Configuration Manual page 703

To view the configuration, use the show config command in LINE mode or the show running-
config in EXEC Privilege mode.
NOTE: Dell Networking recommends using the none method only as a backup. This method does
not authenticate users. The none and enable methods do not work with secure shell (SSH).
You can create multiple method lists and assign them to different terminal lines.
Enabling AAA Authentication
To enable AAA authentication, use the following command.
• Enable AAA authentication.
CONFIGURATION mode
aaa authentication enable {method-list-name | default} method1 [... method4]
– default: uses the listed authentication methods that follow this argument as the default list of
methods when a user logs in.
– method-list-name: character string used to name the list of enable authentication methods
activated when a user logs in.
– method1 [... method4]: any of the following: RADIUS, TACACS, enable, line, none.
If you do not set the default list, only the local enable is checked. This setting has the same effect as
issuing an aaa authentication enable default enable command.
Enabling AAA Authentication — RADIUS
To enable authentication from the RADIUS server, and use TACACS as a backup, use the following
commands.
1. Enable RADIUS and set up TACACS as backup.
CONFIGURATION mode
aaa authentication enable default radius tacacs
2. Establish a host address and password.
CONFIGURATION mode
radius-server host x.x.x.x key some-password
3. Establish a host address and password.
CONFIGURATION mode
tacacs-server host x.x.x.x key some-password
Example of Enabling Authentication from the RADIUS Server
