This counter records the number of frames dequeued, i.e., released for transmission, by this access port's QoS shaper during the current interval. An admin compares this to the port's link rate to verify the shaper is actively releasing the expected volume of subscriber traffic rather than starving the queue. For example, if cmAccPortQosShaperStatsFD is unexpectedly low during a period when the subscriber reports heavy usage, the admin would investigate whether the shaper is under-releasing frames.
