WLC 9800 AirPlay does not work over WLAN

[gary_the_network_guy]

I am performing a migration from an old WLC 5500 to a new WLC 9800. After migrating all accesspoints in one building, all iPads started to have problems with finding airplay monitors , even though they are on the same vlan/wlan.

Any Ideas?

Thank you guys , After configuring the mDns in globaly and creating the mDns policy and service list by adding all the apple services in IN and OUT list. it worked for me. i configured the mDNS in gateway mode.
