Would one expect gigE to gigE traffic local to the NPE-G1 to scale higher than that?

The PA-GE interfaces top out at around 400Mbps before they start dropping packets, even if the pps is low. Your pps numbers are very close to what I recall, though we were hitting the bps issue more. The gig interfaces on the NPE are substantially beefier and scaled beyond this limit, but I doubt that you'll get as much more out of them for pps issues. -- Ross Vandegrift [EMAIL PROTECTED] "The good Christian should beware of mathematicians, and all those who make empty prophecies.
