Good afternoon,
I have a WLC 2106 that I am using for learning purposes. Yes, I know it's obsolete. It's running version 7.0.252.0.
I am trying to understand why multicast does not work between the wireline and wireless networks, or even between two wireless devices. If I open wireshark while connected to the wireless network, I see multicast BJNP (Bonjour) packets coming from my computer, but no other packets show up. If I plug in with a cable, I see all the multicast packets coming through, and Bonjour devices are discoverable.
The wireless SSID is using the same subnet as the wireline network and is in the same VLAN. I have broadcast forwarding turned on in the WLC's controller settings. Also, since this is a 2106, the multicast -> unicast option is not available.
The APs join a multicast group under Monitor -> Multicast, so that seems to be working.
Where could the multicast dropping be happening?
