Traffic Prioritization
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.
The 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.
The following web pages are included in this group:

Optionally, you can use the CLI for configuration, see
QoS Setting
Use this subsection to set up QoS settings for the ES7506.

Queue Scheduling
This is also known as WRR (Weight Round Robin). The ES7506 follows the 8:4:2:1 rate to

process the packets in a queue from the highest priority to the lowest. For example, the
weighted fair
system processes 8 packets with the highest priority in the queue, 4 with middle priority,
