mscAtmIfCARtVbrUnshapedTransmitQueueing
1.3.6.1.4.1.562.36.2.1.114.3.3.100.1.88
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 1pOC12SmLrAtm and 1pOC48SmSrAtm cards this attribute
must be set to common or autoConfigure. This attribute cannot be
set to perVc since per-Vc queueing is not available on the
1pOC12SmLrAtm and 1pOC48SmSrAtm cards. The value
autoConfigure is interpreted to mean common queueing.
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 4pOC12SmIrAtm and 4pOC12SmLrAtm cards only
perVc queueing is supported. All other attribute values are ignored.
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 basic Vpts, and standard Vpt Vccs.
