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 a cumulative counter reset only by an explicit clear rather than on a fixed schedule -- reflecting everything since PM stats were last cleared. For example, since PM counters were last cleared, this pseudowire might show this counter at 9000000 -- a concrete count the admin can trend against neighboring bins to judge whether the condition it reflects is worsening.
