This read-only Counter64 counts bytes received on this PM instance that were remarked (color-marked) yellow — out-of-profile traffic that exceeded its committed rate but was still within the excess-rate allowance. A rising Yellow count is usually the first sign a customer or internal flow is bursting above its committed rate (CIR) into the excess-rate (EIR) band — traffic that forwards fine until congestion hits, at which point yellow-marked frames are the first ones a downstream queue will drop; because it is drawn from this table's currently-accumulating, short-interval bin, it reflects only the last few minutes of activity, so it's the value to watch for a fast-forming problem rather than a long-term trend. On a 10 Gbps aggregation trunk carrying multiple EVCs, this might read 641,000 bytes over the last 15 minutes — a number an admin would divide by the bin length to sanity-check it against the port's 10,000,000,000-bps ceiling.
