This Counter64 field reports the frames received per second on the forward direction of this bidirectional CES tunnel, as computed for this PM instance. 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, and this specific field is an instantaneous computed rate of accepted ingress traffic rather than a running total, so it reacts immediately to a burst instead of waiting for a bin to close, it is the field to check when you need to see the forward-direction ingress throughput of the tunnel right now rather than a cumulative volume. For example, this counter might read 6,824 frames/sec during the period since the last manual clear — if that number spikes on the forward side while the opposite direction stays flat, it flags an asymmetric load or fault specific to that leg of the tunnel.
