policers and queues associated with the policy.
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 should be used as the rounding step value.
If a value of 0 or 0.00 is used, the system will interpret this equivalent to no granularity.
Default
Values
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 as
the child's rounding step value. If a rate step of 0 is specified, the system interprets this equivalent to no
granularity.
Default
Values
limit-pir-zero-drain
Syntax [no] limit-pir-zero-drain
Context config>qos>adv-config-policy>child-control>offered-measurement
Description
This command is used to configure the system to use the minimum configurable PIR instead of an HQoS
derived zero operational PIR. The default behavior is to allow the operational PIR of the queue to remain the
last configured value while setting the queue MBS to zero (preventing queuing of newly arriving packets).
Retaining the previous PIR value may cause a momentary burst above an aggregate rate associated with the
queue as it drains. Using the limit-pir-zero-drain command causes the queue to drain at the lowest rate
possible (typically 1Kbps) which limits overrun situations.
The no form of this command reverts to default behavior.
lub-init-min-pir
Syntax [no] lub-init-min-pir
Context config>qos>adv-config-policy>child-control>offered-measurement
Description This command is used to initialize new queues associated with a LUB context to use a minimum PIR similar
to the effect of the limit-pir-zero-drain command. When a queue is initially created in a LUB context it
defaults to a zero value PIR until HQoS has an opportunity to configure an offered rate based operational
PIR. Enabling this command forces a minimum rate operational PIR to be applied to the queue for use by
enqueued packets prior to an HQoS iteration.
The no form of this command reverts to default behavior.
