This attribute is replaced by new attributes rxCellDiscardClp and rxFrameDiscardClp.

This attribute counts the number of cells or frames received from the interface on this connection with CLP=1 that have been discarded.

If the connection segments frames into cells, the counter indicates the number of frames discarded. Connections which segment frames into cells have a connectionPointType of connectionEndPoint.

If the connection relays cells without adaptation, the counter indicates the number of cells discarded. Connections which relay cells without adaptation have a connectionPointType of segmentEndPoint 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. Thus, in the AAL1 case, this attribute counts discarded cells.

Discards are done due to congestion, non-conformance with UPC or AAL reassembly problems.

The counter wraps to zero if it exceeds its maximum value of (2**64)-1.
