How does Dante use DSCP / Diffserv priority values when configuring QoS?

Switches prioritize packets using what are called DSCP/Diffserv values. Although Dante packet priority values have been chosen to make it simple to configure QoS with many switches (as shown in the video above), some switches require special configuration to recognize and prioritize specific DSCP values.

The table below shows how Dante uses various Diffserv Code Points (DSCP) packet priority values:

Priority Usage DSCP Label Hex Decimal Binary
High Time critical PTP events CS7 0x38 56 111000
Medium Audio, PTP EF 0x2E 46 101110
Low (reserved) CS1 0x08 8 001000
None Other traffic BestEffort 0x00 0 000000
