This counter tallies frames the flow policer marked yellow, indicating they exceeded the committed rate but were still within an allowed excess/burst rate. A rising yellow count signals to an admin that a flow is regularly bursting above its guaranteed rate, which may be acceptable or may indicate the customer needs a rate-plan upgrade. For example, an admin noticing consistently high cmQosFlowPolicerStatsFMY on a business flow might recommend the customer upgrade to a higher committed rate to avoid yellow marking during normal usage.
