The seen NetBIOS traffic is broadcast. I don't know about you, but to me, it's either a switch, or it's not. Since he plainly labeled one device in the diagram as a switch, and one as a hub, I'm assuming he knows the difference. There is no such thing as a switching hub - it's either a switch, or a hub, not both. In any case, his problem may be that he's not in promiscuous mode, for some reason or another, or he actually *does* have a switch there (not intelligent hub, not switching hub, just *switch*).
