RE: speed/duplex on 3560

Did u try a shut / no shut on both sides on the link ?

After that if link still down, check with show int if the speed and duplex are really set to 100 / full on both sides as I've seen a bug on the 3750s where one side goes to 100/half after a bounce on the link.

Cheers, Thiago

  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
