Not sure whether this is true for all operating systems, but in many systems I have come across the following ordering convention:From: Paras pradhan <pradhanparas@gmail.com>I have eight nics and its getting difficult to me which MAC id represents which physical port. Any way to find this?Unless you are 100% sure the nics detection follow a sequential order that matches the nics physical ports order, I think you will have to test them one at a time... JD
