Help with multicast through 2 managed switches

[Flicker20]

Hi all

I'm a newb and I'm having issues getting the configuration correct for a multicast device - it either doesn't work or floods my network when it does work.

I have a HDMI over IP/TCP transmitter connected from my PC upstairs, into a managed switch JGS524PE in port 24. Then in port 22 I have a cable running to downstairs and which meets another smaller switch GS105Ev2 in to port 1. Port 3 then goes to the receiver of the HDMI over IP/TCP device. (Port 5 of said switch goes to my router/modem)

How can I configure this so that both HDMI devices talk to each other and nothing else, and without flooding my network? Or is there a change in configuration/switch that I can do that will make this work?

Thanks

@Flicker20,

Welcome to the community!

Are the switches running the latest FW in which the JG524PE's latest is v2.6.0.48 (release notes here) and the GS105Ev2's latest is v1.6.0.11 (release notes here)?

Another thing you can try is to enable IGMP Snooping Status, Block Unknown MultiCast Address, and Validate IGMPv3 IP header which is located on System > Multicast (see page 51 of the user manual here) to see if that will resolve the issue.

Hi Jerald

Thanks for the reply.

They are both running the latest firmwares.
I have tried multiple settings all involving the IGMP Snooping Status, Blocking Unknown MultiCast Address and Validating IGMPv3 IP headers but I can't work out the full settings of them to make it work

Any help would be greatly appreciated!

Hi @Flicker20,

What you can try here is to create a VLAN only network for the HDMI over IP transmitters then assign the ports to that VLAN accordingly.

If the issue still occurs, I suggest contacting NETGEAR Support by opening a support case (please see KB article here).
