    The tunnel interface view is displayed.

  3. Select one of the following protection switching trigger methods as required:

    • To forcibly switch traffic from the working tunnel to the protection tunnel, run mpls te protect-switch force

    • To prevent traffic from switching on the working tunnel, run mpls te protect-switch lock

    • To switch traffic to the protection tunnel, run mpls te protect-switch manual

    • To clear the configuration of the protection switching trigger mechanism, run mpls te protect-switch clear
