Multicast and wirerless

ggladney — Sun, 04 Jul 2021 06:08:46 GMT

I have a 4404 controller running 6.0.202 code and more more people have Mac running bonjour and wanting to use Airplay. I see how to turn on Multicasting and even provide a Multicast address for IGMP snooping but does anyone have a good feel as to the overall load Multicast adds to the wireless network?

Thanks,

Gary

It depends on the type of deployment you have.

If the network infrastructure supports multicast, you should enable Multicast - Multicast as the controller multicast mode and choose a multicast address in the 239.X.X.X range.

If your network is not capable of supporting multicast, you would want to select Multicast - Unicast mode. This mode puts a load on the controller and on the wireless network as the Multicast is then sent as a unicast to each access point instead.

These support articles should help you.
