If your using a PC to watch the traffic, the NIC will usually also need to support promiscuous mode to see unicast traffic not directed to it.

Thanks, but I'm using ethereal in promiscuous mode, I think the issue is relationed with MAC learnning from any switch across, cuz eventualy I get a single packet when I reconfigure RSPAN, but after only broadcast and multicast.
