[c-nsp] High CPU Utilization

[Campbell, Alex]

It's not really clear from your email but it looks like you are saying
that you are maxing out your Fast Ethernet interfaces.  Is this right?
What is your average packet size?  What services are running on the box
(BGP, firewall etc)?

Even the fastest 2800 model (2851) can barely push 100mbps of small
packets under ideal conditions.  You have FE interfaces rather than GE
so I guess you probably have a 2801 or 2811 which are rated at around 45
and 60mbps respectively.

Dear All,

I have got a cisco 2800 router. its CPU is continously monitored to be
99%.
it has got only two fast ethernet ports and traffic on these ports
reaches to maximum. when you analyze the traffic goin thru these ports,
Max is IP traffic.(98%). i tried fast switching on these ports using ip
route cache on interfaces . but it didnt help in lowering the CPU
utilization.

Advice to lower down the CPU utilization.

Thanks in advance

Ronnie
