Configuration Using the Command Line Interface (CLI)
Traffic Prioritization (CLI)
Quality of Service (QoS) provides a traffic prioritization mechanism which allows you to deliver better service
to certain flows. QoS can also help to alleviate congestion problems and ensure high-priority traffic is
delivered first. This section allows you to configure Traffic Prioritization settings for each port with regard to
setting priorities.
ES9528 QOS supports four physical queues, weighted fair queuing (WRR) and Strict Priority scheme, that
follows the IEEE 802.1p COS tag and IPv4 TOS/DiffServ information to prioritize the traffic of your
industrial network.
Optionally, you can use the web user interface for configuration, see Traffic Prioritization on Page 93. This
table provides detailed information about command lines for traffic prioritization configuration
QoS Setting
Queue Scheduling –
Strict Priority
Switch(config)# qos queue-sched
sp Strict Priority
wrr Weighted Round Robin
Switch(config)# qos queue-sched sp
The queue scheduling scheme is setting to Strict Priority.
Queue Scheduling -
WRR
Switch(config)# qos queue-sched wrr
<1-10> Weights for COS queue 0 (queue_id 0)
Switch(config)# qos queue-sched wrr 10
<1-10> Weights for COS queue 1 (queue_id 1)
………..
Switch(config)# qos queue-sched wrr 1 2 3 4
The queue scheduling scheme is setting to Weighted Round Robin.
Assign the ratio for the 4 classes of service.
Port Setting – CoS
(Default Port Priority)
Switch(config)# interface fa1
Switch(config-if)# qos priority
<0-3> Assign a priority queue
Switch(config-if)# qos priority 3
The priority queue is set 3 ok.
Note: When change the port setting, you should Select the specific port first. Ex: fa1
means fast Ethernet port 1.
