Most if not all of the 10 GbE CASPER packet designs use jumbo packets, instead of the 1500 byte MTU that is usual with fast Ethernet. There's probably a jumbo packet setting somewhere. Hopefully labview or the driver supports such a thing. I'm afraid I don't know anything about Windows stuff at that level. John > > Zhiwei >
