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.
ES7506 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
