Configure the Authentication Method The authentication-mode
command configures the user login authentication method that denies access to
an unauthorized user.
Tabl e 9 describes the authentication-mode command.
Perform the following configuration in user interface view.
By default, terminal authentication is not required for users who log in through
the console port, whereas the password is required for authenticating the modem
and Telnet users when they log in.
To configure authentication for modem and Telnet users:

When you set the password authentication mode, you must also configure a login
password to log in successfully.
Table 10 describes the set authentication
password command.
Perform the following configuration in user interface view.
Configure for password authentication when a user logs in through a VTY 0 user
interface and set the password to 3Com:
[SW7700] user-interface vty 0
[SW7700-ui-vty0] authentication-mode password
[SW7700-ui-vty0] set authentication password simple 3Com

authentication of username and password. The type of the authentication
depends on your configuration. For detailed information, see “AAA and Radius”

VTY 0 user interface and set the username and password to zbr and 3Com
