This read-create Integer32 object, per its description, specifically sets the SLM (Synthetic Loss Measurement) packet size, as a dedicated counterpart to the combined DMM/SLM sizing done by esaProbeCOSConfigPktSize. An administrator uses this when they want the loss-measurement frames to use a different size than the delay-measurement frames on the same CoS row. For example, an operator might keep DMM frames small for frequent delay sampling while setting a larger esaProbeCOSConfigslmPktSize to better emulate real data-frame loss behavior.
