Can anybody confirm if you can establish an Xconnect between two 20Gb port-channels (2x 10Gig bundle).  The core is 40Gig and running MPLS.  We have many gigabit pseudowires running over it already.

Our intention is to terminate 10Gig server traffic on 4900M's and then have a 20Gb Port channel trunk link into a 6500 (which is part of the MPLS cloud).   We would then issue the xconnect directly on the 20Gig port channel in order to traverse the MPLS Core.

Has anyone configured this before?  Are there any caveats to watch out for?  What sort of performance hit (if any does) xconnect functionality have on 10Gig Traffic.
