If it is two switches / two chassis / two boxes connected in some fashion
with fiber, copper, magic switch cable and it can provide a lacp link that
can survive a failure of one of the devices ... it is a multi-chassis link
aggregation capable device as far as I can figure.

I have 7010s, 5020/5010s, 5548s, VSS, 3750s and they all look just the same
to the end device - channel-group xyz mode active.
