When lots of people are on our network, and students/teachers try to stream to the Apple TV it starts to lag. Is there any way to prioritize this traffic above any other? We are only using AP 120's and 121's, and cisco switches (until I can replace them with Aerohive ones.) Thanks

I haven't tested this, but I'll take a stab at getting started with it.

First, I'd define new network services or application services that describe Airplay protocols. As far as I can tell these aren't defined out of the box by Aerohive, except for RTSP as an application service. 

Second, I'd apply those newly defined services to your QoS classifier map (and possibly adjust the marker map if continuing QoS through the LAN, but I'm not sure how much this would affect Airplay).

It gets murky because I don't think Airplay's specifications are freely available officially. But you definitely would need TCP port 7100 which actually contains the video stream that needs to be prioritized.

Unofficial Airplay spec:

Hope this helps!
