Configuring
Authentication Mode
at Login
With the configuration of user interface authentication mode, you can decide
whether to authenticate users when they log on through the specified user
interface, thus enhancing the security of the device. The supported authentication
modes on the device are none, password, and scheme.
■ If you specify the authentication mode as none, then no username and
password are needed when users log on through the specified user interface,
which may be insecure.
■ If you specify the authentication mode as password, then password
authentication is needed when users log on through the specified user
interface. Input of empty or wrong password may result in login failure. Before
terminating the redirected Telnet connection, set the password of the specified
user interface.
■ If you specify the authentication mode as scheme, then username and
password authentication is needed when users log on through the specified
user interface. Input of empty or wrong password may result in login failure.
Before terminating the redirected Telnet connection, set the username and
password.
