Configure AAA Authentication for Login
To enable authentication, authorization, and accounting (AAA) authentication for logins, use the
login authentication command in line configuration mode. AAA services must also be configured.
Configuration Procedure
In this example, the router is configured to retrieve users’ passwords from a TACACS+ server
when users attempt to connect to the router.
From the privileged EXEC (or “enable”) prompt, enter configuration mode and enter the
commands to configure the router to use AAA services for authentication:
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#aaa new-model
router(config)#aaa authentication login my-auth-list tacacs+
router(config)#tacacs-server host 192.168.1.101
router(config)#tacacs-server key letmein
Switch to line configuration mode using the following commands. Notice that the prompt changes
to reflect the
current mode.
router(config)#line 1 8
router(config-line)#
Configure password checking at login.
router(config-line)#login authentication my-auth-list
Exit configuration mode.
router(config-line)#end
