This read-write TruthValue enables or disables a combined rate limit that caps multicast and broadcast packets together as one aggregate on this FlowPoint, rather than limiting each separately as the individual Mcast/Bcast objects do. An administrator would enable this when the flow needs a single shared cap on non-unicast flood traffic instead of maintaining two independent multicast and broadcast limits. For example, enabling this combined limiter on a flow point simplifies configuration for an operator who wants one aggregate ceiling on all flood-type traffic rather than tuning multicast and broadcast limits independently.
