If I recall correctly, the sup720-10G is actually slight faster than a 
sup720 - it's really a "sup760". So the fabric has enough capacity.

As long as you have enough PFC capacity (either because you're using 
DFCs, or because you only have a few ports) then it should work just fine.

That is: the 10G ports are normal ports, and can be used normally.
