This read-only counter tracks how many cells with the Cell Loss Priority bit set were discarded specifically in the egress direction, as distinct from cells dropped purely because the queue was completely full. An administrator uses it to confirm that CLP-based selective discard (via egrQCLPThreshHigh/Low) is actively shedding lower-priority traffic during congestion rather than only affecting egrQfullDiscardCells. A rising count here alongside a flat egrQfullDiscardCells count indicates the CLP discard mechanism is working as intended to protect CLP=0 traffic.
