Sorry, scrap that last conmment - I wrote it before I saw your show int.
The fact is, there is no such thing as a collision in full-duplex. Could this collision count be from a former connection to this port that was operating in half-duplex? Or perhaps with the PC hard-coded and the switchport in auto?
If you clear down the counters now, do the collisions still count up?
Do you have any evidence that the autonegotiation might fail sometimes due to the long cable length. If so, you might do well to hard-code both the PC and the switchport.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
