This is the upper 32 bits of the 64-bit count of egress cells on this channel with CLP set to 1 -- lower-priority, discard-eligible cells -- measured before the traffic management entity acts on them. Together with the low-order cwacsEgrRcvCLP1 or the combined cwacsHCEgrRcvCLP1, it tells an admin how much best-effort/discard-eligible egress traffic is being offered to the channel prior to any shaping, useful for distinguishing traffic-mix issues from downstream discard problems. If a customer reports low-priority data arriving fine but high-priority voice degraded, an admin would check whether this CLP=1 volume is disproportionately large relative to the CLP=0 counters.
