[c-nsp] RX No Buff Errors on 7206 w/NPE-G1

[Vincent Aniello]

Would a NPE-G2 processor be able to handle the microbursts or it a
limitation of the 7200 platform?

Almost every time I've ever been part of a troubleshooting session
for Gige overruns and ignores it's microburst on the segment and the
receiving router can't process the frames quick enough.

It's so hard to debug because without an analyzer on the wire you
can't prove it's a micro burst.

The 65xx/76xx can move those frames are wire rate.

For small packets the G1 can't.
