Description The rate command defines the maximum bandwidth that the scheduler can offer its child queues or
schedulers. The maximum rate is limited to the amount of bandwidth the scheduler can receive from
its parent scheduler. If the scheduler has no parent, the maximum rate is assumed to be the amount
available to the scheduler. When a parent is associated with the scheduler, the CIR parameter provides
the amount of bandwidth to be considered during the parent scheduler's 'within CIR' distribution
phase.
The actual operating rate of the scheduler is limited by bandwidth constraints other then its maximum
rate. The scheduler's parent scheduler may not have the available bandwidth to meet the scheduler's
needs or the bandwidth available to the parent scheduler could be allocated to other child schedulers
or child queues on the parent based on higher priority. The children of the scheduler may not need the
maximum rate available to the scheduler due to insufficient offered load or limits to their own
maximum rates.
When a scheduler is defined without specifying a rate, the default rate is max. If the scheduler is a root
scheduler (no parent defined), the default maximum rate must be changed to an explicit value. Without
this explicit value, the scheduler will assume that an infinite amount of bandwidth is available and
allow all child queues and schedulers to operate at their maximum rates.
The no form of this command returns all queues created with this queue-id by association with the QoS
policy to the default PIR and CIR parameters.
Parameters pir pir — The pir parameter configures the PIR rate of the scheduler in kbps or it can be set to the
cir cir — The cir parameter configures the CIR rate of the scheduler in kbps or it can be set to the
