This counts the total number of valid packets received over this specific pseudowire service instance. RxPkt on this PW is the baseline traffic-volume counter the admin compares against Miss, Missorder, and Malformed to compute an actual loss or error rate for the service, since those defect counts are only meaningful as a fraction of packets actually received -- and this specific object covers the current, still-open 15-minute interval -- a value that keeps climbing until the interval closes and rolls into history. For example, so far in the current, still-running 15-minute interval, this pseudowire might show this counter at 50000 -- a concrete count the admin can trend against neighboring bins to judge whether the condition it reflects is worsening.
