Traffic Prioritization
Quality of Service (QoS) provides traffic prioritization mechanism and 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 switch QOS supports four 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.
