This counter reports the total frames of ingress traffic on this PM instance that were remarked -- allowed through but flagged as exceeding the committed rate while still within the excess rate -- during the entire operational life of the element, uncleared. Because this is a life-to-date total that, by design, defines no clear-time field and so survives any clear applied to its Stats-bin counterpart, a share of yellow traffic that keeps climbing relative to the accepted-traffic total over the tracked span points to a service that has structurally outgrown its committed rate, rather than to one isolated past burst. For example, a life-to-date yellow-frame total dominated by small frames suggests the service's chronic over-committed-rate traffic is signaling or transactional in nature, not bulk transfers, which matters for deciding what kind of rate plan actually fits it.
