| router is c2651, sw is 12.2.19
|  there is an NM-1A-E3 in the chassis
|
| load is: 20M/10M, 2,7kpps/2,3kpps
|    traffic is between an AAL5SNAP encapsulated PVC and Fasteth.
|       (the cpu load was the same with ATM/LANE uplink)
|
| Normally there is CAR on the FastEth, and inACLs on both ATM & FastEth,
| but the CPU won't calm down neither at removal of the CAR, nor at removal
of all the ACLs.
|
| According to published perf data the c2651 can do up to 37-40kpps @64B/pack
| We only have 5-6kpps, why is the CPU running around 80%?
|
| Ok, i know CPU util is not clearly linear with kpps value, but 80% at 5-6
kkps is still strange!
|
| Any idea?
|

Are there VLANs on the FastEth?  If so, what encap?  Can you provide a
sanitized config?
