Configuring an Authentication Mode for the Console or TTY User Interface

You can configure an authentication mode for the console user interface or a TTY user interface to ensure secure login through the reverse Telnet function.

Context

The console or TTY user interface supports AAA authentication and password authentication.

  • AAA authentication: Users must enter both user names and passwords for login. If either a user name or a password is incorrect, the login fails.
