This attribute is replaced by new attributes txCellDiscardClp and txFrameDiscardClp.

This attribute counts the number of cells or frames received from the bus 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 or when the connection's interface is disabled.

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