Traffic Prioritization
Quality of Service (QoS) provides traffic prioritization mechanism which allows users 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 Managed Switch’s QOS supports 8 physical queues, weighted fair queuing (WRR) and
Strict Priority scheme, which follows 802.1p COS tag and IPv4 TOS/DiffServ information to
prioritize the traffic of your industrial network.
Following commands are included in this group:
4.7.1 QoS Setting
4.7.2 QoS Priority Mode
4.7.3 CoS-Queue Mapping
4.7.4 DSCP-Queue Mapping
4.7.5 CLI Commands of the Traffic Prioritization
