Direct traffic switch within linecard rev II

[pknurek]

Can someone confirm that ver2 linecards do or can switch traffice without actually going over crosbar ? There is hardware path within asci/linecard however nothing more.

All linecards (ver1 and ver2) use X-bar on MDS 9500 chassis to route frames. The only switch doesn't use X-bar is MDS 9216 where 2 cards are connected though high-speed back-plane.

Also worth to mention that MDS 9513 chassis doesn't use fabric X-bar module located in sup-2, frames been routed using separate X-bar fabric modules located on backend.
