Stack of 4300 Switches mDNS fails, Dante fails
We bulit a stack of 3 switches, M4300-48X, M4300-28G-PoE+ and M4300-24X. All normal traffic and protocols are running well. Only Dante Controller shows no units in the complete network.

Hi Laurent
We could get Dante finally to work by:- Setting Bonjour to enable and wait for a long time or reboot the complete stack. Disabling Bonjour
does drop ALL Bonjour traffic on the complete stack, not just disable the visibility of the switch itself on browse - Using IGMP in version 2 instead of version 3 suggested by Dante
- Ignore the QOS DSCP settings from the Howto and leave QOS on default settings "trustdot1p"
Support has pending tasks now:
- Fixing Bonjour
- Figuring out correct DSCP settings
- Analyze why IGMP version 3 is not working correct.
Many thanks for your help and from all support staff

Hi thesnake
Thank you for having provided your Tech-Support file to us, I know the Tech Support team came back to you.
Checking in with you to confirm: was the problem solved after you enabled Bonjour in the M4300 switch stack? The Dante mDNS packets aren't blocked anymore, is that right?
We will make the KB clearer here: https://kb.netgear.com/000060205/M4300-Configuration-Guide-for-Dante-Audio-Devices
We used to disable Bonjour on 12.0.7.9 firmware (or older) to ensure the forwarding of Dante mDNS packets. We were resolving a conflict this way, with M4300's own implementation of Bonjour discovery in the network. But we fixed this issue starting 12.0.7.10 and now, by design, we don't need to disable Bonjour anymore.
Bonjour is now enabled by default in M4300 software, no conflict with other Bonjour packets. I believe you run 12.0.7.12 on your stack, please let us know how it goes in your Dante Controller now?
Many thanks,
