Unicast flood on 3750

Hi. There is a unicast flood on 3750 killing slow modem links. How to determine source MAC address of flooder?

Is there a rate limit feature for it?

I know how to block it completely on port-level, but it breaks normal network operation. (when port goes down for some reason, it's learned MACs got flushed and since other hosts know MACs, they keep flooding untill their arp caches expire).

Use storm-control unicast
