So it sounds like the range command is what I want then, if I can systematically adjust the EtherType field (e.g. I can explicitly say start at 0x0 and run to 0xFFFF) just with the caveat that I have to send a burst of packet for each loop iteration? If that is the case I don't mind, it will still get the job done of testing every Ethertype through a DUT. Any chance I can lower the burst size on the CLI to 64 packets for example to speed things up? > Also I am more then willing to take patches :-) Sure, I didn't want to spend hours testing to find out that I can't do what I wanted to do which is why I asked here. Sounds like it can be done so I'll have a poke around with the code and see what I can do. Thanks for your help it is greatly appreciated, James.
