This PerfCounter64 counter reports a count of frames marked Green by the policer, in the upstream (subscriber-to-network) direction in the upstream (subscriber-to-network) direction on this specific subscriber flow. An admin uses it to see whether a flow's own policer, configured for that subscriber's committed rate, is actually enforcing the contracted bandwidth rather than passing everything through unmarked. For a flow provisioned with roughly a 847 Mbps committed rate, a rising cmFlowStatsFMGA2N on flow entry 35 shows the operator this particular subscriber is regularly pushing traffic past what they are paying for, rather than the port itself being congested.
