NDI on the AV4250 switch
Hi, I am looking to isolate issues I am having with packet losses on NDI streams. I have a M4250 receiving various NDI and ND-HX streams from computers and cameras and it gets DHCP and WLAN from a Ubiquiti Edgerouter-X. The router has a NDI6 Profile set as Default and all ports are set to the Default VLAN. So in operation I tend to have port 1 connected to the Router and all the other ports connected to NDI sources (Cameras or Computers) or NDI receivers (Decoders or Computers). Excuse my lack of Network understanding but could one of the causes of Packet Losses (Network traffic issues) be NDI hitting the router and the router. The packet losses I'm experiencing are sporadic not constent. I get zero packet loss for upto a minute then lose packets for about 5 secs before normal network traffic is resumed.
If the router can cause issues can someone recommend the best way to set the router up to give DHCP to my devices connected to the switch without comprimising NDI network traffic.
Many thanks
Frank

Would be new to me this router does have NDI6 profiles. Talking about the switch?
About 5 seconds is the time RSTP convergence recovery takes after a detected network change or failure.
Suggest to install the free https://www.netgear.com/business/solutions/engage-controller/ for keeping easier access to your switch, it's logs, and much more....

To be absolutely clear no NDI streams are directly connected to the ubiquiti router. All devices passing NDI are connected to the Netgear AV Switch but the router is also connected to the switch and on the same VLAN. So my question is: does this setup have the potential for NDI bottlenecks (packet losses) caused by the router.
As an example on my last job I had 3 cameras (2x 4K25p NDI-HX2 and 1x 4K25p Full NDI) connected up to the Netgear Switch and 3 computers receiving or sending NDI. I noticed that the camera feed from the Full NDI PTZ was dropping packets every 1 min or so for 5 seconds on my vMix computer but it was fine on my imac?
