This Counter64 field tallies the frames on the forward 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 is today's still-open 24-hour PM window, which keeps growing through the day and resets only when the daily boundary rolls over, 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 today's still-running 24-hour bin this counter might climb by roughly 5,086,953 forward-direction frames — a step-change in that number right after a config change on this tunnel, with the reverse-direction counter unaffected, would tell you the change altered how much accepted traffic only that one direction is carrying.
