Within a typical service provider environment I can see how broadcast and multicast storm control can be useful. I am confused regarding unicast storm control though.
Reading the Cisco docs online they give examples such as protecting against port flooding if the destination MAC of an incoming frame isn't in the CAM tables. This makes good sense to me. So does
storm-control unicast only measure the pps rate (or bps rate) of frames that are for destinations not in the CAM tables, or all destinations that aren't a broadcast or multicast address (so just the total number of unicast frames)?
I'm worried that configuring such a feature could shut a port down that shouldn't be shut down simply because it has a high pps rate. An example of this is ports with voice services attached that have high frame rates but are low bpp rates of unicast frames.
Is this feature only measuring the frame/packet rate of unknown destination addresses or all unicast frames, what are the dangers here?
