One exciting issue you may run into depends on what cabling you are using!!!
See, the 3560's have this cool thing called "auto-mdix" which means you can
plug in a straight-through or crossover cable and it doesn't matter because
the switch will figure it out.
BUT.... That only works as long as you are still auto on your speed and
duplex. Otherwise, it goes back to the "you figure it out" method of cable
detection.
So if you put your ports back into "auto" do they come up just fine? That'd
be why then.
Dontchya just love progress???? This little feature pissed me off for a
little while before I figured it out when I first started playing with
3560's. (smirk)

Subject: speed/duplex on 3560
Hello:
Does anybody know why you can't lock in the speed and duplex settings on the
Cisco 3560?
I just tryed to condigure some trunks and the links would not come up with
the speed and duplex sett to 100 / full. I tried different combinations of
no mdix auto and that didn't help. Thanks.Mike
