Did you set the speed and duplex on each device on both sides of the
trunk
link?

This is what I did
sw tr en do
sw mo tr
speed 100
dup full
Then I added mdix auto and no mdix auto to try to bring the links up
(incase they weren't crossovers) The links showed up as not
connected.

Mike,
I am able to hard code various speed and duplex settings on my 3560s
and
still trunk. Are you setting the same values on both sides of the
link?
Are you trunking to a router or another 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
