[c-nsp] sup720 etherchannel port preferences?

[Lee]

Is there any performance difference for a two port etherchannel created on a
single WS-X6748 card vs. one port on two different WS-X6748 cards?

We've got a backup server that's maxing out it's 1Gb link and want to give
it some more bandwidth, so I was wondering if it made any difference on
which ports or which cards (all the cards being 6748s) you configured an
etherchannel.

Thanks,
Lee
