Hey,

Regarding your query:

IP SNMP process - Too many things has been polled from the switch using SNMP IOD's. Also check the link:https://supportforums.cisco.com/document/61366/troubleshooting-high-cpu-snmp-engine-process-ios

IP Input process - Too many unncessary packets are being punted to CPU. You may configure the NetDr captures to see what traffic is being directed to CPU and then find out which user is sending that. Check the link for configuring same:https://supportforums.cisco.com/document/59956/troubleshooting-netdr-capture-sup7206500

HTH.

Regards,

RS.
