Except for the part where they said the 4th Gig-E port is a 
PCI-X connection to the board and can run at line rate 
independently.

Never did quite figure that one out :-).

We used the NPE-G2 as a core router many, many years ago, 
and extratced 950Mbps from it (aggregate) with 0% packet 
loss at 91% CPU utilization. v6, v6, MPLS, IS-IS, LDP, RSVP.
