This Counter64 field tallies the frames on the reverse direction of this bidirectional CES tunnel that were accepted on ingress, specifically traffic that passed the tunnel's ingress bandwidth-profile check as in-profile (green) and was let into the tunnel without remarking. Because this Stats row carries no Duration or State field at all, unlike the Curr/History bins — it is a running tally since the last manual clear rather than a fixed-length interval, a rising count here just reflects legitimate billable load flowing through the tunnel in that direction, and tracking it separately per direction (forward vs. reverse) lets you tell whether a problem is one-sided rather than affecting the whole tunnel. For instance, over the period since the last manual clear this counter might climb by roughly 5,152,412 reverse-direction frames — a step-change in that number right after a config change on this tunnel, with the forward-direction counter unaffected, would tell you the change altered how much accepted traffic only that one direction is carrying.
