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 ES7528 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:
• QoS Setting
• CoS-Queue Mapping on Page 104
• DSCP-Queue Mapping on Page 105
Optionally, you can use the CLI for configuration, see Traffic Prioritization (CLI) on Page 182.
QoS Setting
Use this subsection to set up QoS settings for the ES7528.

Queue Scheduling
Use a Round
Robin scheme The Round Robin scheme means all the priority has the same privilege, the traffic is
forward cyclic from highest to lowest.
Use a strict
priority scheme Packets with higher priority in the queue are always processed first, except that there is
no packet with higher priority.
