This holds the upper 32 bits of the 64-bit count of CLP=0 egress cells on this channel counted after they have passed through the traffic management entity, i.e. cells actually transmitted onto the wire. Comparing this post-shaping figure (paired with cwacsEgrXmtCLP0 or the combined cwacsHCEgrXmtCLP0) against the pre-shaping cwacsHighEgrRcvCLP0 value lets an admin see whether the traffic management stage is dropping or delaying high-priority cells. If the transmitted count falls well behind the received count over time, that signals the shaping engine is holding back or discarding priority traffic on this channel.
