Configuring an Authentication Mode for a VTY User Interface

Configuring an Authentication Mode for a VTY User Interface


To configure a VTY user interface to support SSH, you must set the authentication mode of the VTY user interface to AAA; otherwise, the protocol inbound ssh command does not take effect.

The system starts the delayed login mechanism in the case of a device login failure. If the first login fails, the user can log in again 5 seconds later. The delay time is increased by 5 seconds every time a login failure occurs. For example, the second login is delayed to 10 seconds, and the third login is delayed to 15 seconds.


  1. Run system-view

    The system view is displayed.

  2. Run user-interface vty first-ui-number [ last-ui-number ]

    The VTY user interface view is displayed.

  3. Run authentication-mode aaa

    The authentication mode is set to AAA authentication.

  4. Run protocol inbound { all | ssh }

    The VTY user interface is configured to support the SSH protocol.

    By default, a VTY user interface supports the SSH protocol.
