4. To verify how QoS settings are propagated across the network, you can also proceed as
follows:
a. Analyze the network traffic in the switch by using its Switched Port Analyzer (SPAN)
feature (if supported). This method allows mirroring network traffic from the source
port to another destination port in the switch for monitoring and analysis
Mirroring network traffic at a switch
This includes enabling SPAN in the switch, connecting a computer to the destination
port, and installing a network sniffer on your computer.
b. Collect a Wireshark trace at the endpoint farthest from the MCU.
5. Review the tracing logs for changes in the Differentiated Services Code Point (DSCP)
value of each IP packet that defines the service priority level. If the values have changed to
0x0, the QoS tagging was stripped and the traffic is no longer prioritized.
Revert to factory defaults
If none of these troubleshooting procedures help solve the video quality issues, revert the MCU to
factory defaults.
