Values max — The max (maximum) keyword is mutually exclusive with the min and
closest options. When max is defined, the operational PIR for the queue will be
equal to or less than the administrative rate specified using the rate command.
min — The min (minimum) keyword is mutually exclusive with the max and
closest options. When min is defined, the operational PIR for the queue will be
equal to or greater than the administrative rate specified using the rate command.
closest — The closest parameter is mutually exclusive with the min and max
parameter. When closest is defined, the operational PIR for the queue will be the
rate closest to the rate specified using the rate command.

Description
The system creates and associates a port-scheduler with every access port on the system.
Every queue within a SAP is associated with the port scheduler available on the port on
which the SAP is created. This command provides the context to configure the queue
parameters ‘cir-level’ and ‘pir-weight’. The port scheduler uses these parameters to
apportion the bandwidth to all the queues competing for the available bandwidth.
NOTE: Queues with cir-level value set to 8 are treated differently by the software than other
queues configured with different cir-level values. The PIR rate values configured for the cir-
level 8 queues are ignored by software. Only CIR rate value is used and PIR is set to CIR
value. In addition, when executing the no form of the rate command for a queue configured
at cir-level 8, the default CIR (and PIR) value is set 1. Please read the cir-level description
under port-parent CLI command description for more information about the scheduler
behavior for queues configured with cir-level value of 8.
The no form of the command sets the cir-level and pir-weight to default values.
Default
port-parent cir-level 1 pir-weight 1
Parameters cir-level cir-level —
Specifies the priority of the queue with respect to other queues. The
priority of the queue is used only in the CIR loop. Level "8" is the highest priority and level
"1" is the lowest priority.
