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 the industrial network.
Following commands are included in this group:
4.8.1 QoS Setting
4.8.2 QoS Priority Mode
4.8.3 CoS-Queue Mapping
4.8.4 DSCP-Queue Mapping
4.8.5 CLI Commands of the Traffic Prioritization
4.8.1
QoS Setting
In QoS setting, you should choose the QoS
Priority Mode first, Port-Based, Cos or DSCP
modes. Choose the preferred mode and you can
configure the next settings in its own
configuration pages. The other page of the mode
you don’t select can’t be configured.
Queue Scheduling
A administrator can select the Queue
Scheduling rule as follows:
Use a strict priority scheme. Packets with
higher priority in the queue will always be
processed first, except that there is no packet
with higher priority.
Use Weighted Round Robin scheme. This
