Usage Guidelines

Usage Scenario

To manage and monitor login users, configure the VTY user interface for login users and run the protocol inbound command to configure the protocols that the VTY user interface supports.


If SSH is configured for the user interface using the protocol inbound command, you must configure the authentication-mode aaa authentication mode to ensure successful logins. If the password authentication mode is configured, the protocol inbound ssh command cannot be executed.


  • The configuration takes effect at the next login.

  • When SSH is specified for the VTY user interface, the SSH server function is enabled, and the RSA key is not configured, a user cannot log in to the SSH server using SSH.


# Configure SSH for user interfaces VTY0 to VTY4.
