Try running tcpdump on the receiving PC. If you are using tgtap logic, you should see occasional arp traffic from the roach to work out where to send its data. Some switches have UDP flood protection - if they see lots of UDP traffic, especially broadcast UDP, they throttle it down. If tgtap is running and I remember things correctly, data destined for machines which do not respond to arp traffic will be broadcast. Alternatively if the destination MAC is all zeros, switches typically discard traffic instead of sending it on. I believe you are one of the first people to use the GbE port, so please let us know of your progress. regards marc
