atmIfCARtVbrUnshapedTransmitQueueing 1.3.6.1.4.1.562.2.4.1.114.3.3.100.1.88

This attribute specifies the default queuing option for unshaped connections of the rt-VBR service category. This attribute controls whether common or per-VC queueing is used. Per-VC queueing means that each connection has its own buffering and queue limits. Common queueing means that cells are queued in First In First Out order on a common queue for this service category. The common queue has one set of congestion control levels for all cells enqueued on it. For ATM IP cards, if traffic shaping for this service category is disabled, this attribute may take any of the three values. In this case, the value autoConfigure is interpreted to mean per-VC queueing. For ATM IP cards, if traffic shaping for this service category is not disabled, the only permitted values are perVc and autoConfigure. In this case, the result is that all connections use per-VC queueing. For CQC-based ATM cards, if the perVcQueueInterfaces attribute of the Lp Eng Arc Cqc component permits shaping for this interface, then this attribute may take any of the three values. In this case, the value autoConfigure is interpreted to mean per-VC queueing. For CQC-based ATM cards, if the perVcQueueInterfaces attribute of the Lp Eng Arc Cqc component does not permit shaping for this interface, then this attribute may take values common or autoConfigure. In this case, the value autoConfigure is interpreted to mean common queueing. If this attribute is set to autoConfigure, an override to this default may be specified for a provisioned connection under the Vcd Tm or Vpd Tm component. The opUnshapedTransmitQueueing attribute of this component indicates whether the transmit queueing is perVc or common. This attribute does not apply to standard Vpt Vccs and basic Vpts.
