configuration mode. The commands provisioned in this mode are applicable for all the interfaces that have

storm-control pfc in queue-drop

When a PFC storm is detected on a port or priority, you can drop the traffic meant for the specified port or priority, so that

dropping of the traffic on all the lossless queues of the port.
