Hrm. A switch that can be taken down by a single NIC sending any amount
of broadcast traffic it's capable of sending sounds like a broken switch
to me.
Put another way, if I found a switch in my network that could be taken
out in any way at all by a single NIC, I would be replacing it
immediately either by another of the same switch (assuming it's just a
broken piece of equipment) or another make/model (assuming it's
defective by design).
