Dante VC mic not working across Meraki network

[NOS48]

Hi,

I have a Meraki network, end to end, with a new Dante VC setup.  All seems to be working fine other than the Microphones.  The kit has been checked and double checked and it has been suggested to me to setup an IGMP querier, which I have done (via this link-Configuring Meraki Switches for Shure Devices and Dante/AES67).

However, it doesn't seem to have made any difference.  I didn't follow the process for defining the QSO>COS assignments, as Meraki seems to have a level of them already configured.  Also, I was unsure on the exact process and didn't want to just start messing with a live network.

Has anyone else come across this issue before, and resolved?

Thank you.  I did see this post and I had run through the process detailed, already.  However, it's not made any difference.  I'm now wondering if there's a strange anomaly with this VC kit and how it's interacting with the Meraki kit.  It just makes no sense...I suspect I may need to run this past the Meraki support team

I suggest you open a support case.

Have you created the IGMP querier on the VLAN that the microphones are on?

Are the microphones and the VC main unit on the same VLAN?

How many switches do you have and how are they linked?

[NOS48]

Yes, I created the IGMP querier and the microphone is on the same VLAN as the querier.

The microphone and VC main controller are also on the same VLAN.

We have 5 switches, the core switches are linked by an aggregation link and the others just by a single trunk link back to the core.

Is the IGMP querier on the switch that the mic is plugged into?

[NOS48]

Yes, the IGMP querier and the mic are on the same switch.  It's an edge switch, with a trunk link back to the core.

Have you tested this on a switch other than Meraki? Just to isolate the problem.

What model is the edge switch?
