You may be on to something but I'd have to research it. The switch and
NMS are on the same subnet and, now that I think about it, the NMS is
connected to the same switch that I'm on.
Hmm.....that makes this even stranger! Since this is unicast traffic
destined for the switch itself, I wonder why it would ever flood that
traffic out any port. Hmmm....
Very ponderous.
Another oddity is that I'm seeing directed broadcast traffic from a LAN
subnet that exists two hops away over our WAN and there is no ip helper
address configured on that router. I have *no* idea how that could be
happening!
These LAN analyzers point out the most interesting things! ;-)

You would also see flooded unicast traffic until the switch learns the
correct port to use for a destination MAC address. That might not
explain
the SNMP traffic though. That just sounds like a leak!?
