1.1.4 Set 'login authentication for 'line tty'


Authenticates users who access the router or switch using the TTY port.


Using AAA authentication for interactive management access to the device provides consistent, centralized control of your network. The default under AAA (local or network) is to require users to log in using a valid user name and password. This rule applies for both local and network AAA.


Enabling Cisco AAA 'login authentication for line TTY' is significantly disruptive as former access methods are immediately disabled. Therefore, before enabling Cisco AAA 'login authentication for line TTY', the organization should plan and implement authentication logins and passwords, challenges and responses, and token technologies.


Configure management lines to require login using the default or a named AAA authentication list. This configuration must be set individually for all line types.

hostname(config)#line tty {line-number} [ending-line-number]
hostname(config-line)#login authentication {default | aaa_list_name}

Default Value:

Login authentication is not enabled.

Uses the default set with aaa authentication login.
