SET QOS SCHEDULING

Syntax

set qos scheduling=strict|wrr weights=

weights

Parameters

scheduling

Specifies the type of scheduling. The options are:

strict

Strict priority. The port transmits all packets

out of the higher priority queues before it
transmits any from the low priority queues.
This is the default.

wrr

Weighted round robin. The port transmits a

set number of packets from each queue in a
round robin manner.

weights

Specifies the weight given to each of a port’s four

egress priority queues. You must specify the weights if
scheduling will be weighted round robin. The range for
each queue is 1 to 15 packets, and the default is 1. The
weights are specified in the following order: Q0, Q1,
Q2, Q3. For example, to assign Q0 a weight of 1, Q1 a
weight of 5, Q2 a weight of 10, and Q3 a weight of 15,
you enter this parameter as

weights=1,5,10,15

. The

parameter must include all four queues.

Description

Sets the QoS scheduling method and the weights for round robin
scheduling.

Examples

The following command sets the scheduling to strict:

set qos scheduling=strict

The following command sets the scheduling to weighted round robin and
gives egress priority queues Q0 and Q1 a weight of 5, and Q2 and Q3 a
weight of 15:

set qos scheduling=wrr weights=5,5,15,15
