If the device and DDM can't communicate over the network for any reason, you won't be able to control Dante settings,
perform a factory reset, or update device firmware. When the connection is reestablished, the device follows the policy set
for it in the Dante domain.
If Dante device lock is on, DDM is offline, or the configuration of the device is set to Prevent, some device settings are dis-
abled. These include: Dante encryption, MXW association, AD4 Dante browse and Dante cue, and SCM820 linking.
See Dante Domain Manager's documentation for more information.
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.

Low (2) (reserved) CS1 0x08 8 001000
None (1) Other traffic BestEffort 0x00 0 000000
Note: Switch management may vary by manufacturer and switch type. Consult the manufacturer's product guide for specific configuration details.

Networking Terminology
PTP (Precision Time Protocol): Used to synchronize clocks on the network
DSCP (Differentiated Services Code Point): Standardized identification method for data used in layer 3 QoS prioritization
Dante Transmit Flows
For each device, there is a limit of 2 transmit flows and 2 receive flows. A single flow consists or either a single unicast or
multicast transmission, and supports up to 4 audio channels.
A unicast flow is a point-to-point connection between 2 devices, supporting up to 4 channels per flow. To send 8 channels
of audio between two devices, 2 unicast flows are required.
A multicast flow is a one-to-many transmission, which supports sending up to 4 channels to multiple receiving devices
across the network. To send 8 channels from one device to all others on the network, 2 multicast flows are required.
Networking Best Practices
When connecting Shure devices to a network, use the following best practices:
Always use a "star" network topology by connecting each device directly to the switch or router.
