Parameters percent-of-admin-pir — When the percent qualifier is used, the following percent-of-admin-pir
parameter specifies the percentage of the child’s administrative PIR that used as the fair share
increase limit. The new operational PIR result is capped by the child’s PIR. If a value of 0 or
0.00 is used, the system will disable the fair share increase function and only configure the
actual distribution rate. If a value of 100 or 100.00 is used, the system will interpret this
equivalent to executing the no above-offered-cap command and return the fair-share
operation to the default behavior.
Default None, an increase limit percentage value must be specified when
the percent qualifier is used.
Values 0.00 to 100.00
rate-in-kilobits-per-second — When the rate qualifier is used, the following rate-in-kilobits-per-
second parameter specifies an explicit number of kilobits-per-second (1000 bits-per-second)
that should be used as the limit to the child’s fair share increase to the operational PIR. The
new operational PIR result is capped by the child’s PIR. If a value of 0 is used, the system
will disable the fair share increase function and only configure the actual distribution rate.
Default None, an increase limit rate value must be specified when the rate
qualifier is used.
Values 0 to 100,000,000
enqueue-on-pir-zero
Syntax [no] enqueue-on-pir-zero
Context config>qos>adv-config-policy>child-control>offered-measurement
Description This command is used to enable queuing of new packets when HQoS determines that a queue should
stop forwarding (operational PIR set to zero). The default behavior is to allow the queue to continue
to use the previously determined operational PIR and set the queue’s MBS (Maximum Burst Size) to
zero. This prevents new packets from being admitted to the queue until the PIR zero case terminates.
The new behavior when enqueue-on-pir-zero is enabled is to set the operational PIR to zero and leave
the queue’s MBS set to the normal value.
This command is ignored for FP1 based forwarding planes as this feature is not supported on Q1 traffic
management devices. This command overrides the limit-pir-zero-drain command for FP2 and above
forwarding planes that are based on the Q2 or greater traffic management devices.
The no form of this command reverts to default behavior.
