We are experiencing high CPU utilization on one of our ML Card in the ONS 15454. The "IP Input" has relatively higher CPU utilization consumed irrespective of the proper fast/CEF switching enabled on the interfaces. We are trying to figure out,whether there is an attack to the control-plane or even any IP Packets destined local to the ML Card,which is causing those packet to process switched.
In order to figure that,we thought we may try to use Control plance policing on the control-plane but it seems not taking the service-policy associated with that. Is this feature supported in the ML card or any other suggestion would be really appreciated.
