Cisco Router 7206vxr showing high CPU

Hi,

It is clear from the show process cpu command the utilization is due to interupts. This might be because of several reasons. Refer the below URL for further troubleshooting

Since the CPU is mostly interrupt, it's possible this is due solely due to your volume of traffic also with your configuration.

What's the aggregate volume of traffic passing through the router when the CPU is like that?

Does your configuration use ACLs, NAT, NBAR, etc.?

What model NPE are you using, a -G1 or -G2, etc.?

What's your traffic average packet sizes?
