Problem | Symptoms
Multicast traffic is not being received by the multicast subscribers across the mixed environment of Netgear and Cisco switches, despite confirming that both switches have proper IGMP snooping configurations and correct IGMP snooping querier reports.
Symptoms may include:
- Q-SYS devices not being discovered by each other
- Inability to find AES67/Dante streams in the dropdown list
- Failure to receive video streams, with status reports indicating no video from the encoder
- Display of a "Camera offline" image even when the preview screen of the camera is active
Causes | Verification
If the Cisco switch is the IGMP querier, Cisco switches do not forward IGMP membership reports to the Netgear switch, and the Netgear switch does not send the streams to the Cisco switch after the 600-second (default) membership interval.
Solution | Workaround
- Configure the Netgear switch as the IGMP querier
OR (If you would like to keep the Cisco switch as the IGMP querier)
- Navigate to the Main UI of the Netgear switch > Switching > Multicast > IGMP Snooping > Configuration
- Disable “Exclude Mrouter Interface Mode”
- Save the configuration
