Function description: When setting the QoS function, first select QoS Mode in the drop-down menu. Then you can use 802.1p Priority and DSCP Priority functions. You can enable/disable QoS Mode and set Priority Control, such as 802.1p and DSCP. The switch only supports Strict Priority. High priority queue is always passed first.

Function name: 802.1p QoS Mode

Function description: This function will affect the priority of VLAN tag. Based on the priority of the VLAN tag, it can arrange 0–7 priorities that can map to 4 queues of the switch (low, normal, medium, high) and possess different bandwidth distribution according to your weight setting.

Parameter description:

Prioritize Traffic: Five Prioritize Traffic values are provided: Custom, All Low Priority, All Normal Priority, All Medium Priority, and All High Priority.

The QoS setting applies to all ports on the switch if one of the following values is selected: All Low Priority, All Normal Priority, All Medium Priority, or All High Priority.

Port Number: When Custom is selected for Prioritize Traffic, you may assign a specific Port Number for 802.1p Configuration.

802.1p Configuration: Each Priority can select any Queue. In Default, Priority 0 is mapping to Queue normal, Priority 1 is mapping to Queue low, Priority 2 is mapping to Queue low, Priority 3 is mapping to Queue normal, Priority 4 is mapping to Queue medium, Priority 5 is mapping to Queue medium, Priority 6 is mapping to Queue high, and Priority 0 is mapping to Queue high.
