mscAtmIfTxFrameDiscard 1.3.6.1.4.1.562.36.2.1.114.150.1.18

This attribute is not applicable and is not displayed on CQC-based ATM cards. This attribute counts frames discarded and not transmitted out the ATM interface. This count is independent of txCellDiscard. Transmit 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. The counter is reset to zero when the component is activated, or when any critical attribute of the component is changed. The counter wraps to zero when it exceeds its maximum value of (2**64)-1.
