Info:
Campus based APs with Controllers running 6.4.3.7
ClearPass based role assignment
Chromecast ver2
We have gazillions of AppleTV's that work fine
The Issue:
We have two SSID's, one using 802.1x and the other is open and controlled by CPPM Guest, each with separate VLANs. I have joined AppleTV's to both the 802.1x and open network and sucessfully shared them using AirGroup configuration in CPPM.
The Chromecast however....not so much! The controller AirGroup config has all services enabled, I can see that the device has the correct roles assigned and is showing up in the AirGroup server list.
Both Android and iOS devices running the Google Cast app can see and configure and it SAYS that's ready to cast to.
However, you cannot actually cast any media to it on ANY platform (iOS, Chromebook, Chrome Browser, Android), it just doesn't show up. I have read a few threads (mostly about earlier AOS versions) and tried everything in them but it simply refuses to show up.
