This is the native 64-bit counter of valid CLP=1 cells in the ingress direction of this channel counted after the traffic management entity. It shows how much low-priority ingress traffic actually made it past policing onto the switch, and an admin comparing it to cwacsHCIngRcvCLP1 can quantify how aggressively CLP=1 traffic is being policed on this connection. A rising gap between received and transmitted CLP1 volume would indicate the connection's contracted rate is being enforced against best-effort traffic.
