Cannot run tcpdump easily in this situation -- I think the DHCP client is in the player binary, so the player has to be running. And tcpdump has difficulty with monitoring an interface that's not "UP" yet.

But I could run tcpdump on another machine, on a shared hub with the empeg, rather than on a switch. Anything the other machine sees, then the Empeg must also see since all traffic would be shared.

Cheers
