Configuring BPDU Protection on a Switching Device
Configuring BPDU Protection on a Switching Device
Procedure
Run:
system-view
The system view is displayed.
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-recoverycause bpdu-protectionintervalinterval-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.
