QoS (Quality of Service) Settings
QoS settings assign priorities to specific data packets on the network, ensuring reliable audio delivery on larger networks with
heavy traffic. This feature is available on most managed network switches. Although not required, assigning QoS settings is
recommended.
Note: Coordinate changes with the network administrator to avoid disrupting service.
To assign QoS values, open the switch interface and use the following table to assign Dante -associated queue values.
•
Assign the highest possible value (shown as 4 in this example) for time-critical PTP events
•
Use descending priority values for each remaining packet.
Dante QoS Priority Values

Medium (3)

None (1)
Other traffic
Note: Switch management may vary by manufacturer and switch type. Consult the manufacturer's product guide for specific configuration details.
