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.
