You might also check with your carrier, if one involved, to make sure nothing is in the middle that may be errantly emitting frames (CDP/LLDP, STP, etc).

Thanks, Jeremy. I was hoping you could provide just that sort of detail. I'm just not sure how there would be multiple coming from my side when this is a P2P link and the switch port is in route-only mode; I may have to work with Brocade on that. I will look into it, but can you tell me if the MAC addresses appear to be all from the same vendor?
