Configuration Using the Web Interface
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 ES9528 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
• Port-Based Queue Mapping on Page 94
• CoS-Queue Mapping
on Page 94
• DSCP-Queue Mapping
on Page 95
Optionally, you can use the CLI for configuration, see Traffic Prioritization (CLI)
on Page 164.
QoS Setting
Use this subsection to set up QoS settings for the ES9528.
QoS Setting Page
QoS Priority
Mode
Choose the QoS Priority Mode first, Port-Based, CoS or DSCP modes. Choose the
preferred mode and you can configure the next settings in their own configuration pages.
Queue Scheduling
Use a strict
priority scheme
Packets with a higher priority in the queue are always processed first.
Use Weighted
Round Robin
scheme
This scheme allows you to assign new weight ratio for each class. The 10 is the highest
ratio. The ratio of each class is:
Wx / W0 + W1 + W2 + W3 (Total volume of Queue 0-3)
Apply
Click Apply to apply the settings.
Note: You must Save the settings (Page 124
), if you want to maintain these settings if the
ES9528 is powered off.
