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.
ES7528 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 103. This
table provides detailed information about command lines for traffic prioritization configuration
QoS Setting
Queue Scheduling –
Round Robin
Switch(config)# qos queue-sched
rr Round Robin
sp Strict Priority
wrr Weighted Round Robin
Switch(config)# qos queue-sched rr
The queue scheduling scheme is setting to Round Robin.
Queue Scheduling –
Strict Priority 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 1 1 1 1 1 1 1
The queue scheduling scheme is setting to Weighted Round Robin.
Port Setting –
Priority
Switch(config)# interface fa1
Switch(config-if)# qos priority
DEFAULT-PRIORITY Assign an priority (7 highest)
Switch(config-if)# qos priority 7
The default port priority value is set 7 ok.
Note: When change the port setting, you should Select the specific port first. Ex: fa1
means Fast Ethernet Port 1.
Display – Queue
Scheduling Switch# show qos queue-sched
QoS queue scheduling scheme: Weighted Round Robin (Use an 8,4,2,1 weight)
