Hello @Beschtia
Apple does not need the IGMP v3 protocol at the moment. You never know if that will change. Or if you use another TV provider that needs the protocol.
If you are already upgrading your network with new switches. Then I would make sure that the new switches can use the protocol. And that the whole thing is future-proof.

Beschtia The Swisscom TV boxes use multicast for live TV. The Apple TV boxes do not. This is simple “Internet” traffic. You don’t need anything special for that. I don’t currently know of any 2.5 GBit/s switches that are managed, i.e. settings can be made.
But this switch seems to be new: https://www.dlink.com/de/de/products/dms-105-5-port-2_5g-multi-gigabit-desktop-switch
It says: “And the IGMP snooping feature reduces unwanted multicast traffic so you can enjoy seamless video streaming and IPTV.”
So that would be ideal. Here is another link to Brack.ch
