This read-only Counter64 is the frame-level counterpart of the Forwarded-bytes counter — frames successfully sent out on this PM instance. A frame-count jump with flat byte growth usually means the average frame size collapsed — for example a burst of small control packets — which this pairing exposes even when total throughput looks unremarkable; because it is drawn from this instance's running statistics bin, it behaves like a long-running total rather than a rotating window, so admins baseline against it instead of expecting it to reset daily. On a 10 Gbps wholesale handoff port, this might read 53,600,000 frames over the current statistics window, which an admin would cross-check against the matching byte counter to see if average frame size looks normal for that service.
