atmIfVpcVpdTmTxWredThreshold 1.3.6.1.4.1.562.2.4.1.114.4.2.2.100.1.73

This attribute determines at what percentage of the queue being at the EPD threshold, WRED starts. When the value is set to 25%, WRED starts as soon as the queue is 25% of the way to the EPD threshold. When the value is set to 50%, WRED starts later, after the queue is 50% of the way to the EPD threshold. When the value is set to 75%, WRED starts only when the queue is 75% of the way to the EPD threshold. The EPD threshold is 85% of the transmit queue length. This attribue is ignored if txWredMode or txPacketWiseDiscard is disabled. It is always ignored on CQC-based ATM FP.
