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 the current, still-open 24-hour bin for today, the number keeps climbing until midnight rollover, so it should be read as "so far today" rather than a finished daily total. On EVC 105 (E-Line, 100 Mbps CIR/1 Gbps EIR), this might read 60,300,000 frames over today so far, which an admin would cross-check against the matching byte counter to see if average frame size looks normal for that service.
