Solved: Global Multicast Mode but exclude Guest WLAN

emily00001 · ‎01-31-2017

I'm on a 2504 and had Global Multicast Mode set to on. This worked on all the controllers WLANs. On the guest WLAN I enabled P2P blocking but noted that the multicast was still active there. I tried to disable the Global Multicast Mode on the controller and use Multicast VLAN Feature on the WLANs where I wanted multicast to work but that apparently doesn't work when global multicast mode isn't checked.

What do I do to have multicast on for only some of my WLANs? Is it at all possible?

This is expected behavior. You cannot control multicast traffic using P2P blocking feature. Pls have a look at "restrictions for peer-to-peer blocking" section of below document

from WLC level, I do not think there is a solution. But at the switch level you can disable PIM on the interface defined for guest wireless users. That should helps
