I finally found a single reference after a *lot* of searching on CCO that indicates in 12.0(4)T, full duplex capability was added to ethernet interfaces on the 2600 and 3600 platforms. I found this in a list of caveats that mentioned a situation where this would not work even though it was supposed to. I found no other reference anywhere that mentioned this was possible. This actually makes me pretty happy because I upgraded a 2611 a while back and it would help us out greatly if those ports could do full duplex. To the person who pointed this out, I thank you!
