No authentication line {console | sty | web} login
Function:

for the login user. The no form command restores the default authentication mode.

Web login method by default.

Global Mode.
Usage Guide:
The authentication method for Console, VTY and Web login can be configured respectively. And authentication
method can be any one or combination of Local, RADIUS or TACCACS. When login method is configuration in
combination, the preference goes from left to right. If the users have passed the authentication method,
authentication method of lower preferences will be ignored. To be mentioned, if the user receives correspond
protocol’s answer whether refuse or incept, it will not attempt the next authentication method (Exception: if the local
authentication method failed, it will attempt the next authentication method); it will attempt the next authentication
method if it receives nothing. And AAA function RADIUS server should be configured before the RADIUS
configuration method can be used. And TACACS server should be configured before the TACACS configuration
method can be used.
The authentication line console login command is exclusive with the login command. The authentication line
console login command configures the switch to use the Console login method. And the login command makes the
Console login to use the passwords configured by the password command for authentication.
If local authentication is configured while no local users are configured, users will be able to login the switch via the
Console method.

To configure the Telnet and ssh login method to use RADIUS authentication method.
