 Strict: This method services high traffic queues first; low priority queues are delayed until no

more high priority data needs to be sent. The Strict method always gives precedence to high

priority over low priority.

3.6.2 Configuring Traffic Prioritization

Quality of Service (QoS) provides a traffic prioritization capability to ensure that important data is

delivered consistently and predictably. The Weidmüller switch can inspect IEEE 802.1p/1Q layer 2

CoS tags, and even layer 3 TOS information, to provide a consistent classification of the entire

network. The implemented QoS capability improves your industrial network’s performance and

determinism for mission critical applications.

3.6.2.1 QoS Classification

NOTE: Generally the priority of an ingress frame is determined in following order:

1. Port Priority

2. Inspect TOS

3. Inspect CoS

There are two QoS classification settings depending on the specific model of the switch.

Type

Models Supported

Type 1

IE-SW-VL05M/VL08M series, IE-SW-PL06M/PL08M/PL09M/PL10M series

Type 2

IE-SW-PL16M/PL18M series

Type 1 (IE-SW-VL05M/VL08M series, IE-SW-PL06M/PL08M/PL09M/PL10M series)

The Weidmüller switch supports inspection of layer 3 TOS and/or layer 2 CoS tag information to

determine how to classify traffic packets.
