Telnet Login Authentication Modes
Three authentication modes are available for telnet login: none, password, and scheme.
z
none: Requires no username and password at the next login through telnet. This mode is
insecure.
z
password: Requires password authentication at the next login through telnet. 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 telnet.
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.
