Does it hold though that etherchannel traffic gets replicated to all
modules with bundle members?
No.
(ie. does a bundle spanning two 6724's
consume bandwidth on both module's fabric connections, irrespective
of the egress port?)
No, it is filtered on ingress to the fabric by the LTL/FPOE logic.
Would this also be true for ports behind
different fabrics of a dual fabric card (ie. opposite ends of a
6748)?
The filtering is effective on a per fabric channel basis, so only the
half of the card w/the member port selected to actually tx the packet
will get the packet over the fabric.
