Yea the silence not good for the community :-)

So Wash, is this resolved? Also what IOS version, protocols and services are you running on the box?

Regards,

Sometimes the silence really helps!

I decided to patiently dig information about this issue and made very good progress:

1. https://www.cisco.com/c/en/us/support/docs/routers/7500-series-routers/41160-highcpu-ip-input.html

2. https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c02768100

More details.

While digging, I have disabled snmp-server and some debug logging configs.

Now I have:

C1841#sh processes cpu sorted

CPU utilization for five seconds: 64%/17%; one minute: 78%; five minutes: 66%

 PID Runtime(ms)     Invoked      uSecs   5Sec   1Min   5Min TTY Process

 121      467636      134723       3471 45.27% 55.87% 47.09%   0 IP Input

I still think this is high, no? I need to figure out what exactly comprises IP Input
