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

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!? Priscilla At 04:40 PM 7/17/01, John Neiberger wrote: >I'm running a demo of some LAN analysis

I'm running a demo of some LAN analysis software from my PC which is connected to a non-SPAN port. So, I should only see unicast traffic to/from my workstation, broadcasts, and multicasts, right? right! However, from time to time I see unicast packets that are neither destined for or originated
