User interface view

none: Performs no authentication.

password: Performs local password authentication.

scheme: Performs authorization and authentication of AAA. For details about 
AAA, refer to “AAA Configuration Commands” on page 1913.

command-authorization: Performs command line authorization. HWTACACS 
allows per-command authorization. An input command is executed only after it 
passes authorization. For details about HWTACACS, refer to “HWTACACS 
Configuration Commands” on page 1975.

Use the authentication-mode command to set the authentication mode when 
users log onto the device using the current user interface.

By default, the authentication mode is password for TTY (asynchronous 
interface), VTY, and AUX user interfaces and is none for Console interfaces.

# Set that no authentication is needed when users use VTY 0 interface to log onto 
the device. (This mode may be insecure.)
