Configuring BPDU Protection on a Switching Device
Procedure
- Run:
system-viewThe system view is displayed.
- Run:
stp bpdu-protectionBPDU 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.
