Telnet login authentication modes
The following authentication modes are available for telnet login: none, password, and scheme.
• none—Requires no username and password at the next login through telnet. This mode is insecure.
• password—Requires password authentication at the next login through telnet. Keep your password.
If you lose your password, log in to the SecBlade card through the console port to view or modify
the password.
• 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. Keep your username and password. If you lose your
password, log in to the SecBlade card through the console port, and check or modify the telnet
password.
The following table lists telnet login configurations for different authentication modes.
