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 eight
egress priority queues. You must specify the weights if
scheduling will be weighted round robin. The range for
each queue is 0 to 15 packets, and the default is 1. The
weights are specified in the following order: Q0, Q1,
Q2, Q3, Q4, Q5, Q6, Q7. For example, to assign Q0
and Q1 a weight of 1, Q2 and Q3 a weight of 5, Q4 and
Q5 a weight of 10, and Q6 and Q7 a weight of 15, you
enter this parameter as
weights=1,1,5,5,10,10,15,15 . The parameter must
include all eight 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 to Q3 a weight of 1, and Q4 to Q7 a
weight of 15:
set qos scheduling=wrr weights=1,1,1,1,15,15,15,15
