IGMP over multi XS1930

Mar344

We use two XS1930 switches to exchange multicast data from AV devices. Both switches are connected via an SFP+ / fiber optic cable via a trunk port.
This means that both switches have transmitter and receiver devices. There are receivers on Switch 1 which receive data from a transmitter on Switch 2 and vice versa.
Local IGMP works perfectly on both switches. If switches are connected together, I have to switch IGMP off.
Only one switch is configured as a querier.
What configuration must be made so that IGMP works via both switches in a VLAN?
We have activated the Layer3 option on both devices.

Hi @Mar344 ,

You can refer to the Networked AV Mode Wizard section in the XS1930 User Guide (pages 65-75).

If the issue still recurs, please share the following information when two XS1930 switches are connected together:

1. Complete network topology including Switches and Transmitter and receiver devices positions, connected port.
2. Detailed symptoms you observe
3. Tech-support files generated after the symptoms occur

Hi
In order for IGMP to function correctly across multiple switches, the Querier switch requires a management IP address on the multicast VLAN.
Furthermore, ‘Unknown Multicast Frame to Querier Port’ must be set to ‘Forwarding’ on the remote switches.
Now our test setup works perfectly.
