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.
ES8509-XT 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 98. 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
<cr>
Queue Scheduling -
WRR Switch(config)# qos queue-sched wrr
Port Setting – CoS
(Default Port Priority)
Switch(config)# interface gi1
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. gi1
means Fast Ethernet port 1.
Port Setting – Trust
Mode- CoS Only
Switch(config)# interface gi1
Switch(config-if)# qos trust cos
The port trust is set CoS only ok.
Port Setting – Trust
Mode- CoS First
Switch(config)# interface gi1
Switch(config-if)# qos trust cos-first
The port trust is set CoS first ok.
Port Setting – Trust
Mode- DSCP Only
Switch(config)# interface gi1
Switch(config-if)# qos trust dscp
The port trust is set DSCP only ok.
Port Setting – Trust
Mode- DSCP First
Switch(config)# interface gi1
Switch(config-if)# qos trust dscp-first
The port trust is set DSCP first ok.
