This counter records the number of frames dropped at this flow point because ingress class-of-service processing was disabled. A rising count alerts the admin that traffic requiring CoS classification is being dropped rather than processed, which points to a configuration gap where CoS was turned off but traffic still expects it. For example, if a customer's prioritized voice traffic starts experiencing loss right after a config change, the admin would check cmFlowPointStatsFdicd to see if ingress CoS was inadvertently disabled on that flow point.
