This attribute specifies the default maximum queue length for the
emission queues used to buffer the traffic of the rt-VBR service
category. It is used as the basis for setting the discard thresholds on
both common and per-VC queues. For the common queue, the
discard thresholds are set at approximately 35, 75, and 90 percent of
the value of this attribute for traffic at discard priority 3 (DP=3),
DP=2, and DP=1 respectively.
For a per-VC queue, the actual limit may be reduced depending on
the shaping rate of the connection (for standard Vpt Vccs, this is the
shaping rate of the Vpt). The discard thresholds are set at
approximately 35, 75, and 90 percent of the scaled queue limit for
traffic at discard priority 3 (DP=3), DP=2, and DP=1, respectively.
However, a reduction will never result in a value that is less than the
value set for the minPerVcQueueLimit attribute.
When the value of this attribute is autoConfigure, an appropriate
value is selected based on the card type. It is set to 288 for low
speed cards such as DS1, E1 and IMA, and set to 480 for high
speed cards such as JT2, DS3, E3 and OC3 (including ATM IP
FPs). For the 1pOC12SmLrAtm card, the value is set to 2048.
For the 1pOC48SmSrAtm card, the value is set to 12288.
For ATM IP FPs, the per-VC queue limit may be overridden for a
permanent connection by specifying a value in the Vcd Tm or Vpd
Tm txQueueLimit attribute.
For CQC-based ATM cards, the valid range for this attribute is from
5 to 30000 inclusive.
For 1pOC48SmSrAtm cards, the value of this attribute is used to set
the maximum size of the link-class queue for buffering this traffic
type on the egress path.
The operational value of the maximum length of a queue (common
or per-VC) is indicated by the Vcc Tm, Vpc Tm, or Vpt Tm
txQueueThresholds attribute.
For standard Vpts, this attribute does not apply when using per-VC
queuing and only applies when using common queueing. When
using per-VC queueing, regardless of the Vpt's service category,
standard Vpts use the AtmIf Ca NrtVbr txQueueLimit value as their
default.
