First, just off the top, it doesn't make any sense. What if you have a "dumb" auto-negotiating switch? I have such a switch, a Linksys EtherFast II 16port 10/100. There is no way to tell the switch what setting any of the ports should be in, nor have I ever needed such an option. The switch has never failed to negotiate the correct setting with whatever is plugged into it, nor has it ever had a problem matching whatever I assign to an interface I have plugged into it. This is evidenced by the fact that the switch has two LEDs per port. The first one is either green for 100Mbit or orange for 10Mbit, the second is on if the port is full-duplex, off if it's half-duplex. I think perhaps you should stop repeating yourself and go read up on how autonegotiation actually works.. what you've been saying is only true (in my experience) if you're plugging one NIC directly into another via a crossover cable.
