This Counter64 field tallies the frames on the forward direction of this bidirectional CES tunnel that were dropped on ingress, specifically traffic that the policer discarded outright on ingress because it exceeded even the excess-rate allowance. Because this TotalStats row has neither a clear-time nor a Duration/State field — it is the true lifetime, never-reset total for this PM instance since it was provisioned, any nonzero, growing count here is real traffic loss the attached service is experiencing in that direction, not just a policy flag, 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 lifetime of this PM instance this counter might climb by roughly 1,546 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 dropped traffic only that one direction is carrying.
