Qos (Quality Of Service) Settings; Packet Bridge - Shure Microflex Complete Wireless MXCW Complete User Manual

• Quality of Service (QoS) with 4 queues
• Diffserv (DSCP) QoS, with strict priority
• Recommended: A managed switch to provide detailed information about the operation of each network link (port speed,
error counters, bandwidth used)

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
Priority Usage
Time-critical PTP
High (4)
events
Medium (3) Audio, PTP
Low (2) (reserved)
None (1) Other traffic
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

Packet Bridge

Packet bridge enables an external controller to obtain IP information from the control interface of a Shure device. To access the
packet bridge, an external controller must send a query packet over unicast UDP* to port 2203 on the Dante interface of the
Shure device.
1. Send a UDP packet with a minimum 1-byte payload .
Note: The maximum accepted payload 140 bytes. Any content is allowed.
2. The Shure device will send a response packet over unicast UDP to the controller, using a destination UDP port identical
to the source port of the query packet. The payload of the response packet follows this format:
Bytes
0-3
4-7
DSCP Label Hex
CS7 0x38
EF 0x2E
CS1 0x08
BestEffort 0x00
Content
IP address, as 32-bit unsigned integer in network order
