Description
Use this command to activate the timer for the RSTP BPDU guard feature.

convergences by disabling edge ports if they receive BPDUs. When the
timer is activated, the switch will automatically reactivate disabled ports.
The time interval that ports remain disabled is set with “SPANNING-TREE
ERRDISABLE-TIMEOUT INTERVAL” on page 841.
Confirmation Command
