M4250-40G8F-PoE+ with crestron NVX having multicast issues
This should be straight forward however i'm facing an issue setting up AV solution for a client with stand alone M4250-40G switch and 30 NVX Tx and 5 NVX Rx. Using the AV UI i selected the Video with AE67 audio profile, created a VLAN with DHCP server.
However the minute one stream is started and displaying i cant connect to the rest of NVX units, the units seems to be disappearing from toolbox! which looks like a multicast flooding issue.
Tried factory resetting, selecting video only mode, using one VLAN, firmware upgrade the units and the switch with no luck. multicast range on the NVX units are 239.0.0.xx.
Any help is appreciated!
- I am sorry about your issue, if my guidance below doesn't solve it, please send a message (email) to ProAVDesign@netgear.com with the tech-support file of your M4250 switch (AV UI, Diagnostics / Support Diagnostics) and one of us will root cause it rapidly today.
If you created a new VLAN with the Video+AES67 Audio and placed all ports in it, it means that the default Management VLAN 1 is now empty and down, impacting vital functions of the switch including IGMP Multicast.
Management VLAN on a switch always needs to be up!
2 solutions to me:
- Either keep it this way and move the Management VLAN to your new VLAN ID. To do that, AV UI, welcome page. Find the Management IP Address section, click the little pen, and configure the Management VLAN IP and VLAN ID to your new VLAN. Click Apply, and save.
- Or, start from scratch by factory reset (AV UI, Maintenance) and this time, don't create a new VLAN. Under Network Profiles/ Configure, edit the default VLAN 1 there using the 3 little dots under Configured Profiles. Change the template to Video+AES67 Audio, and configure the DHCP server you need. I am assuming you are using the OOB port for configuration. Apply, then Save - it should fix it nicely!

Thanks for your advice, i was able to factory reset the switch and enable the video with AE67 audio profile on the default VLAN and it worked flawlessly.
In future if i want two multicast enabled VLAN, what should i do?
Thanks again!
- Thank you for reporting your success!
No problem, you can create as many other new VLANs/Profiles you want, with Multicast.
As I said, as long as the switch Management VLAN is up, there's no limitation in the number of VLANs.
So now that your Management VLAN is doing NVX multicast, you can create plenty of other AV Profiles/VLANs.
