This counter tracks the total bytes transmitted in Fibre Channel frames on this LUN/flow, the outbound counterpart to ciscoScsiFlowRxFc2Octets. An admin comparing transmit octets across flows sharing a single uplink or ISL can identify which specific host-to-array path is the dominant consumer of outbound fabric bandwidth, useful when planning to isolate a heavy workload onto its own dedicated path. A backup job's flow showing outbound octet counts dwarfing every other flow on that switch during its nightly run would confirm it as the bandwidth hog during that window.
