How can I reduce Multicast on my network?
I am not sure how to reduce multicast on my network. it looks pretty high.
UCG-Fiber -> UXG PRO -> 2 iPhones, 1 MacBook Pro, 1 HomePod
Mac Studio connected by ethernet. (the rest are not Apple Devices)
In the settings activated I have : Multicast to unicast, IGMP Snooping
