Multicast enabled or not ?

Clem58 — Mon, 05 Jul 2021 16:04:46 GMT

Hello,

We have a WLC 5520 with 3802E/I APs in flexconnect (local switching).

The Global Multicast is not enabled.

In the General tab the multicast is on multicast/multicast mode with 239.x.x.x group

Is this multicast mode is enabled even if the global multicast mode is not enabled ?

Because as we are running with flexconnect mode, we need to do multicast-unicast I assume.

You don't need multi cast because you are running AP in flexconnect. You need multicast if you are running some application that requires multicast.

The wireless controller may use multicast to deliver information to the APs but it is part of the management process and you don't need to worry about.

No. Refer below thread as it got useful information about multicast with FlexConnect.
