We are running a cisco 2811 router in office with route and NAT.
Router#show processes cpu
CPU utilization for five seconds: 51%/46%; one minute: 50%; five minutes: 43%
I know the most of CPU time is used to process interrupt. I don't know what is these interrupts working for , route or nat?
We have about 40 desktops in our office, and there is only one defaut route for internet on the router. Also, We enable the NAT on the router.
What I want to know is what is usring the most of CPU. Can anyone give some advise?
