Large campus network: best practices for Airplay (+ issues with lots of Apple TV's)

New Contributor III
We have a large campus network: ZoneDirector ZD1200, ± 50 AP's R500 and R510, ± 100 Apple TV's, lots of iPads (1:1 and shared iPads). The Apple TV's and iPads are on the same SSID, but in small VLAN's/subnets. The backbone of our network has high performance. WiFi speed and reliability are perfect.
We use AirPlay mirroring to the Apple TV's to cast the screen of the teachers iPads to the projector or TV screen. We don't use Bonjour Gateway. From time to time, we experience drop outs or lag in the Airplay streaming

We'd like to know, when configuring a WiFi network for AirPlay with lots of Apple TV's:
  • What are the best WLAN settings?
  • What are the best settings for things like self healing, background scanning, load balancing, etc...?
  • What are the best settings for the AP's?
  • Any other best practices to make AirPlay reliable?
Any help or advice is greatly appreciated.


@pieter_schepens Thanks for the follow up after all this time. So often the OP gives no follow up.

We have gone to mDNS gateway services in our HP Aruba Core stacks with good success but even that can have issues from time to time.
