This read-write CmPmBinAction lets a management station issue a clear command against this network port QoS shaper history bin. It gives an administrator a way to purge retained uplink shaper history, for instance once it has been archived or after a major re-provisioning of the network port's shaping profile. For example, after re-tuning the uplink shaper following capacity growth, an operator might clear f3NetPortQosShaperHistoryAction bins to avoid mixing pre- and post-upgrade trend data.
