Even with “ip options drop”, we are still seeing a fraction of packets being
cpu switched (about 0.2% input and 1% output) even though we are using CEF.
Looks like they are mostly door-knob packets destined for the router itself
(which is ACL’d) or some other annoyance. We tuned the buffers to
on a 1. The 7200 uses particles, not buffers...
Also, its not relevant for CEF-switched traffic. So unless your configuration
requires fast-switching or process-switching, you don't need to worry about
buffer/particle tuning at all.

Sure, but thats not

All,
This is what I am seeing on 7206's with NPE-G1's running IOS 12.4(12b).
Also I might add that I have quite a few of these in service (all with same
rev of IOS, and all are variable traffic throughout a 24 hour timespan
(50-300Mbps):

Hello,
I wanted to reach out to the list to see what is the current and
trusted version of IOS for Cisco 7206VXR with NPE-G1? I know this
hardware is EOL but we have a few still in use and wanted to get them up to
a newer version of IOS. We are currently running 12.4(12b) which I think
we are

15.1(4)M10 has been extraordinarily nice for us - and is about the only
version which has bugfixes for

You might also want to bump up your buffers on the 72xx.
Well ...

Basically, as I understand it, you can get input/output drops with a busy CPU
on the 7200 not just with interface buffer overruns but generic queue buffers.
The default values were set when T1s were the standard. The article shows how
to see which buffers are being overrun and how to adjust
