the packet are canceled. This prevents packets that are discarded by the parent policer from consuming the
child policers PIR, CIR and FIR bandwidth.
The policer-control-policy root max-rate setting may be overridden on each SAP or sub-profile where the
policy is applied.
Default max
Parameters kilobits-per-second — Defining a kilobits-per-second value is mutually exclusive with the max parameter.
The kilobits-per-second value must be defined as an integer that represents the number of kilobytes that
the parent policer will be decremented per second. The actual decrement is performed per packet based
on the time that has elapsed since the last packet associated with the parent policer.
Values Integer 0 – 2000000000
max — The max parameter is mutually exclusive with defining a kilobits-per-second value. When max is
specified, the parent policer does not enforce a maximum rate on the aggregate throughput of the child
policers. This is the default setting when the policer-control-policy is first created and is the value that
the parent policer returns to when no max-rate is executed. In order for the parent policer to be effective,
a kilobits-per-second value should be specified.
no max-rate — The no max-rate command returns the policer-control-policy’s parent policer maximum rate
to max.

Description This command contains the root arbiter parent policer’s min-thresh-separation command and each priority
level’s mbs-contribution command that is used to internally derive each priority level’s shared-portion and
fair-portion values. The system uses each priority level’s shared-portion and fair-portion value to calculate
each priority level’s discard-unfair and discard-all MBS thresholds that enforce priority sensitive rate-based
discards within the root arbiter’s parent policer.
The priority-mbs-thresholds CLI node always exists and does not need to be created.
Default None.
