This read-only counter tracks the total number of frames the bridge has forwarded between its ports since it was last reset. An admin monitors this counter's rate of increase to confirm the bridge is actively passing traffic, and a value that stops climbing during known network activity would indicate a forwarding problem. For example, a sudden flattening of bdgdeviceFrFwd during business hours when traffic is normally heavy would prompt the admin to investigate why the bridge stopped forwarding frames.
