View
User interface view
Parameter
password: Performs local password authentication.
scheme: Performs local or remote authentication of username and password.
none: Log in without authentication.
Description
Use the authentication-mode command to configure the authentication method for
login user.
Use the authentication-mode none command to configure no authentication.
This command with the password parameter indicates to perform local password
authentication, that is, you need to configure a login password using the set
authentication password { cipher | simple } password command.
This command with the scheme parameter indicates to perform authentication of local
or remote username and password. The type of the authentication depends on your
configuration. For detailed information, see “Security” section.
By default, terminal authentication is not required for local users log in via the Console
port. However, password authentication is required for local users and remote Modem
users to log in via the AUX port, and for Telnet users and VTY users to log in through
Ethernet port.
Note: If the Console port is configured for local password authentication, the user can
directly log in to the system even without a password configured; if other user interfaces,
such as the AUX port and VTY interface, are configured for local password
authentication, users cannot log in to the system without a password.
Example
# Configure local password authentication.
