Discovery of AirMedia2 from wireless clients

Eric_Gohringer — Thu, 16 May 2019 22:19:08 GMT

I am trying to discover AirMedia2 controllers on wired ports from wireless devices. I have extended my wireless VLAN to wired ports to do this. When I send a discovery request from a device on a wired port i see requests from said device targeting 255.255.255.255 as well as the subnet broadcast address. When I send a discovery request from a wireless device i see requests from said device targeting 255.255.255.255, but do not see requests targeting the subnet broadcast address. There is nothing in my Role that prevents this traffic from passing. What am I missing here?

What type of device is doing the request? From what I remember multicast is involved as well. By default the controller has a rule to block multicast per topology.

I am using a Windows laptop for testing. We will also need to discover from Android and iOS devices eventually. I do see a multicast request on the wireless. I didn't notice that before.

I enabled Multicast Bridging for 224.0.0.251/32 (mDNS Bonjour) as that is the destination I am seeing in the discovery trace. I can now discover from a Windows10 PC, but not from my Pixel 2XL. I'll test from some other devices to see where this goes.

What is the drawback to enabling Multicast Bridging?

Multicast traffic can use up a lot of your wireless medium, I would suggest giving us a call in the GTAC so we can help you work through different options.
