Configuring Wred - H3C S3100-52P Operation Manual

Operation Manual – QoS-QoS Profile
H3C S3100-52P Ethernet Switch
Note:
The queue scheduling algorithm specified by using the queue-scheduler
command in system view takes effect on all the ports. The queue scheduling
algorithm configured in port view must be the same as that configured in system
view. Otherwise, the system prompts configuration errors.
If the weight (or bandwidth value) specified in system view for a queue of WRR
queuing or WFQ queuing cannot meet the requirement of a port, you can modify the
weight (or bandwidth value) for this port in the corresponding Ethernet port view.
The new weight (or bandwidth value) takes effect only on the port.
If the weight (or bandwidth value) specified in system view for a queue of SP-WRR
queuing or SP-WFQ queuing in the command cannot meet the requirement of a port,
you can modify the weight (or bandwidth value) for this port in the corresponding
Ethernet port view. The new weight (or bandwidth value) takes effect only on the
port.
The display queue-scheduler command cannot display the queue weight (or
bandwidth value) specified in Ethernet port view.
III. Configuration example
Adopts WRR for queue scheduling, setting the weights of the output queues to 2, 2,
3, 3, 4, 4, 5, and 5 (in the order queue 0 through queue 7).
Verify the configuration.
Configuration procedure:
<Sysname> system-view
[Sysname] queue-scheduler wrr 2 2 3 3 4 4 5 5
[Sysname] display queue-scheduler
Queue scheduling mode: weighted round robin
weight of queue 0: 2
weight of queue 1: 2
weight of queue 2: 3
weight of queue 3: 3
weight of queue 4: 4
weight of queue 5: 4
weight of queue 6: 5
weight of queue 7: 5
