Configuring BPDU Protection on a Switching Device

Configuring BPDU Protection on a Switching Device


  1. Run:


    The system view is displayed.

  2. Run:

    stp bpdu-protection

    BPDU protection is enabled on the switching device.

    By default, BPDU protection is disabled on a switching device.

Follow-up Procedure

If you want an edge port to automatically recover from the error-down state, run the error-down auto-recovery cause bpdu-protection interval interval-value command in the system view to configure the auto recovery function and set a recovery delay on the port. Then a port in error-down state can automatically go Up after the recovery delay. Note the following when setting the recovery delay:
  • The auto recovery function is disabled by default and does not have a default value for the recovery delay. When you enable the auto recovery function, you must set a recovery delay.
  • A smaller interval-value indicates a shorter time before an edge port goes Up, and a higher frequency of Up/Down state transitions on the port.
  • A larger interval-value indicates a longer time before an edge port goes Up, and a longer service interruption time.
  • The auto recovery function takes effect only for the interfaces that transition to the error-down state after the error-down auto-recovery command is executed.
