cpu

Hi Team,
I have cisco CISCO3945-CHASSIS running with "c3900-universalk9-mz.SPA.154-3.M3.bin" ios where I can observe the high cpu utilization.

#sh process cpu sorted | ex 0.00
CPU utilization for five seconds: 97%/95%; one minute: 96%; five minutes: 96%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process

I am not able to observe any high load in the interfaces.

Re: cpu

That output only covers only part of only, that not count full 95%, we can not assume what is other processes consuming rest of the CPU.

Re: cpu

"I am not able to observe any high load in the interfaces."

What do you consider high, as Cisco recommends the 3945 for up to 150 Mbps (duplex)?

As most of your CPU usage is interrupt CPU, and assuming your interfaces are running at gig, likely you're bumping into the performance limits of the router.
