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.
ES8508 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
table provides detailed information about command lines for traffic prioritization configuration

Switch(config)# qos queue-sched sp
<cr>
Switch(config)# qos queue-sched wrr
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.
Switch(config)# interface fa1
Switch(config-if)# qos trust cos
The port trust is set CoS only ok.
Switch(config)# interface fa1
Switch(config-if)# qos trust cos-first
The port trust is set CoS first ok.
Switch(config)# interface fa1
Switch(config-if)# qos trust dscp
The port trust is set DSCP only ok.
Switch(config)# interface fa1
Switch(config-if)# qos trust dscp-first
The port trust is set DSCP first ok.
