This read-only Counter64 counts bytes received on this Carrier Ethernet PM instance that the switch accepted — bytes that passed ingress classification and policing rather than being dropped or re-marked. Admins read it alongside the Yellow and Dropped byte counters on the same flow point to see what fraction of offered load is within its committed profile and actually getting forwarded; because it is drawn from this instance's running statistics bin, it behaves like a long-running total rather than a rotating window, so admins baseline against it instead of expecting it to reset daily. On a 10 Gbps wholesale handoff port, this might read 12,000,000 bytes over the current statistics window — a number an admin would divide by the bin length to sanity-check it against the port's 10,000,000,000-bps ceiling.
