This read-only Counter tallies the number of frames discarded on ingress specifically because Usage Parameter Control (UPC) policing measured the traffic exceeding CIR plus EIR, the combined committed-plus-excess rate allowance. An administrator watches this counter to confirm that policing enforcement against the CIR+EIR contract, rather than a simple queue-depth or DE-threshold discard, is the cause of loss on a channel. For example, a channel whose rcvFramesDiscUPC rises sharply after a traffic burst indicates that burst exceeded even the combined CIR+EIR allowance and was policed away rather than merely being DE-marked.
