This read-only Counter tallies the number of packets transparently forwarded by the bridge from the row's source port to its destination port. An administrator monitors this per-port-pair counter to understand actual traffic volume flowing transparently between two specific ports, useful for capacity planning or confirming expected traffic patterns. For example, if this counter between two ports stays at zero despite an expected traffic flow, the admin suspects a cabling or VLAN misconfiguration is preventing transparent forwarding between them.
