Modem Login Authentication Modes
Three authentication modes are available for modem dial-in login: none, password, and scheme.
z
none: Requires no username and password at the next login through modems. This mode is
insecure.
z
password: Requires password authentication at the next login through the console port. Keep
your password. If you lose your password, log in to the device through the console port to view or
modify the password.
z
scheme: Requires username and password authentication at the next login through the console
port. Authentication falls into local authentication and remote authentication. To use local
authentication, configure a local user and related parameters. To use remote authentication,
configure the username and password on the remote authentication server. For more information
about authentication modes and parameters, see AAA Configuration in the Security
Configuration Guide. Keep your username and password. If you lose your password, see H3C
Series Ethernet Switches Login Password Recovery Manual for password recovery.
