atmIfVpcStatsRxCellDiscard 1.3.6.1.4.1.562.2.4.1.114.4.140.1.82

This attribute counts the number of cells received from the interface on this connection that have been discarded. This count is included in the rxCell attribute. This count includes cells discarded due to non-conformance with UPC, cells which are part of a frame which has been discarded due to an AAL5 frame reassembly error, cells which are discarded due to congestion, or cells which are received while the next hop connection to which the traffic is directed across the backplane is down. The next hop connection is the Vcc or Vpc identified by the nextHop attribute of the Nrp or Rp component. For CQC-based ATM cards, this attribute is applicable only to connections that relay cells without adaptation. Such connections have a connectionPointType of connectionEndPoint or connectingPoint. AAL1 connections are an exception to this rule; although they have a connectionPointType of connectionEndPoint, they do not do adaptation at this point. For Vpts, this attribute provides an aggregated total of all rxCellDiscard values for all such connections associated with the Vpt. For CQC-based ATM cards, for Vpcs, and Vccs that relay cells without adaptation, this attribute is not applicable and is not displayed. Discards due to non-conformance with UPC at the VP layer, for a standard Vpt Vcc, are not included in this attribute. These discards are counted in the Vcc's parent Vpt rxCellDiscard attribute. The counter wraps to zero if it exceeds its maximum value of (2**64)-1.
