Network Queue QoS Policy Commands
In the PIR loop, the priority of the queues cannot be configured. The system assigns the priority to
the queues based on the cir-level associated with the queue. to see the default assignment of pir-
levels to the queue corresponding to the cir-level configured by the user.
Values
Default
pir-weight pir-weight — Specifies the relative weight of the queue with respect to the other queues. The
weight parameter is used only in the PIR loop. If a queues level parameter is set to '8', the weight
parameter is ignored by the system.
Values
Default
queue-mgmt
Syntax queue-mgmt < name >
Context config>qos>network-queue>queue
Description
This command specifies the WRED and buffer parameters associated with the queue.
All the queues in the system allocate buffers from the system pool.
Parameters name —
rate
Syntax rate [cir cir-percent] [pir pir-percent]
no rate
Context config>qos>network-queue>queue
Description
This command defines the administrative Peak Information Rate (PIR) and the administrative
Committed Information Rate (CIR) parameters for the queue. The PIR defines the maximum rate
that the queue can transmit packets through the port. Defining a PIR does not necessarily
guarantee that the queue can transmit at the intended rate. The actual rate sustained by the queue
can be limited by oversubscription factors or available egress bandwidth. The CIR defines the rate
at which the system prioritizes the queue over other queues competing for the same bandwidth.
The rate command can be executed at anytime, altering the PIR and CIR rates for all queues
created on the access ports.
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
