mscAtmIfVpcStatsTxFrameDiscard 1.3.6.1.4.1.562.36.2.1.114.4.140.1.46

This attribute counts the number of frames received from the bus on this connection that have been discarded. Frames are discarded due to congestion, Partial Packet Discard (PPD), Early Packet Discard (EPD), and Weighted Random Early Detection (W-RED) mechanisms, or when the connection interface is disabled. This count is independent of the txCell or txCellDiscard attribute. For CQC-based ATM cards, this attribute is applicable only to connections that segment frames into cells. Such connections have a connectionPointType of connectionEndPoint. 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 txFrameDiscard 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 EPD, PPD, and W-RED for a standard Vpt Vcc are not included in this attribute. These discards are counted in the Vcc's parent Vpt txFrameDiscard attribute. The counter wraps to zero if it exceeds its maximum value of (2**64)-1.
