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
Q0 to Q6 is 1 to 15 packets. The range for Q7 is 0 to 15
packets. A setting of 0 of Q7 means that its packets
always take priority over the packets in the other
queues, and that packets are transmitted from the other
queues only when Q7 is empty.
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.
The default setting for all queues is 1. At the default
setting, all queues have the same weight.
Description
Sets the QoS scheduling method and the weights for round robin
scheduling.
Examples
The following command sets the scheduling to strict:
