Telnet, Console and AUX Port Passwords on Cisco Routers Configuration Example

  • The login command enables password checking at login.
  • If the login command isn’t applied, the console port won’t prompt for authentication.
  • For Cisco IOS v12.2 and newer, you cannot set the login command before a password is set on a line.
    • If you were able to “enable password checking at login,” but did not set a password, that line won’t be usable. You’ll get prompted for a password that doesn’t exist.
    • Cisco IOS prior to v12.2 did not have this “password” then “login” restriction.

Tools / Utilities

  • PuTTY Manager

Set password for console access:

(config)# line console 0
(config-line)# password <password_here>
(config-line)# login
