Hank,
Every time I've ever worked on this it's microburst.
The only real way to fix it is a hardware forwarding box that
can do packets at line rate gige.

That's only applicable if you have a lot of process switched traffic
and you see input drops in 'sh int'.
If you do see input queue drops and the throttle count in 'sh int'
is going up you might be impacted by that bug.

On the other side, of those NPE-G1 ports, do you see any flow control from
them? I've never seen a G1's counters show pause frame that it sends, but

I'm running a Cisco 7206/VXR with an NPE G2, Version 12.4(4)XD4
acting as an LNS.
I'm getting input errors consistently incrementing on the Gig
interface (ignored errors)
Any way to fix this? I saw some discussion a while back about this,
and it seemed to have to do with buffers - but I
Can you bump up your input queue depth:
hold-queue 4096 in
and see if they stop.

No luck... didn't fix it. Is it fixed in a subsequent release? Are
there any other parameters I can tune?

Not really because you can't tune the rx ring depth.
Check 'sh controller'.
What does 'sh proc cpu sort | excl 0.00'
ring sizes: RX = 128, TX = 256
rx_particle_size: 512
rx_pak = 0x0444F908
rx_head = 122
Here are the sh controller and sh proc results.
I'll send the config directly - too much to sanitize ...
Thanks!
