mDNS issues with EWC on 9120AXI

[D-KA]

Hi!

I've built a new wireless setup at home with 9120 access points (coming from 2 Aironet 2800's), using the EWC. Now I'm struggling with mDNS. With the old setup, I didn't had this problem.

The network itself and all network flows work as they should. But for mDNS traffic I have some strange behavior. I've attached the network diagram and also a matrix of the issue, because it would be hard to describe. In short words: Airplay works (almost), Airprint does not. Inside the service list for global mDNS I included all services in and out. I checked several Cisco documentations for mDNS and now I'm lost. I don't know what's going on. Perhaps somebody has an idea where I have to look at. Would be very helpful!
