Fair enough. Every vendor has gone through their own pain with the older
midplane systems in having to swap out chassis multiple times to get to higher
speeds. Thankfully with the newer fabric designs we've eliminated most of that.

Sorry was thinking 400GE to 100GE breakout. You can certainly do 4x10GE
breakouts on the various 8000s boxes and line cards.
Thanks,
