Cisco Storm-Control default action when an optional action is configured I have looked through as much Cisco, and other, documentation as I could find on the subject, but I couldn't find a solid answer on this question. The default action for an interface that exceeds the configured storm-control level is to drop the traffic. However, what happens to an interface when you configure one of the optional behaviors? It would seem that the traffic _would_ continue to be dropped, in addition to the configured behavior. But I can't find evidence of this. Here I've configured a storm-control action of _'trap'_ , along with rise and fall thresholds. storm-control action trap storm-control broadcast level 40.00 30.00 storm-control multicast level 40.00 30.00 storm-control unicast level 40.00 30.00

Always blocking traffic, in your case all kind of multicast,unicast in addition.

Your choice can be shutdown port or send snmp trap, but all of it would be happen after blocking. cisco off doc
