jfrizzell: Your config from switch-01, is that a copperport (RJ45)?
Because "speed 1000" can be problematic due to the fact that the IEEE standard says you need to use auto/auto regarding speed/duplex when it comes to gbit and higher speeds. I have seen this confusion happen between a cisco switch and a hp switch - which was fixed once you set auto/auto on both ends (even if it felt wrong compared to how bad autoneg worked back in the 10/100 days for some equipment :P).
