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.

ES7510 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 (Use an 8,4,2,1 weight)

Switch(config)# qos queue-sched sp

Queue Scheduling -
WRR

Switch(config)# qos queue-sched wrr

Port Setting – CoS
(Default Port Priority)

Switch(config)# interface fa1

Switch(config-if)# qos cos

DEFAULT-COS Assign an priority (7 highest)

Switch(config-if)# qos cos 7

The default port CoS value is set 7 ok.

Note: When change the port setting, you should select the specific port first. fa1

means Fast Ethernet port 1.

Port Setting – Trust
Mode- CoS Only

Switch(config)# interface fa1

Switch(config-if)# qos trust cos

The port trust is set CoS only ok.

Port Setting – Trust
Mode- CoS First

Switch(config)# interface fa1

Switch(config-if)# qos trust cos-first

The port trust is set CoS first ok.

Port Setting – Trust
Mode- DSCP Only

Switch(config)# interface fa1

Switch(config-if)# qos trust dscp

The port trust is set DSCP only ok.

Port Setting – Trust
Mode- DSCP First

Switch(config)# interface fa1
