This read-write CmPmBinAction lets a management station issue a clear command against this traffic port shaper statistics bin. It gives an administrator a way to reset a physical port's shaper counters, for example after changing the port's shaping rate, so new behavior can be measured cleanly. For example, after increasing a port's shaping rate to relieve congestion, an operator would clear cmTrafficPortQosShaperStatsAction to baseline the improvement from a clean slate.
