I don't think that we are. We are running Enterprise Services, but we did as close to an in-place upgrade as we could. Of course we had to reconfigure several of the interfaces because they no longer are in the same location.
I did notice a line within the config that I've not seen in previous revisions:
ip device tracking
That seems to indicate that there is some port tracking turned up. I'm going to try and play with this on a testing switch and see if there are negative ramifications to removing this line. I'll post my results.
