I think the major mdns enhancement on 7.5 is that AP can forward mdns advertisements from wired side to controller. So wireless client can see Apple TV on wired as long as it is on the same vlan with the AP.
http://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn75.html#wp784178 "In Release 7.4, the controller could learn the mDNS services that are visible only on the network. In this release, the mDNS AP feature allows the controller to have visibility of wired service providers, which are on VLANs that are not visible to the controller. You can configure any AP as an mDNS AP to allow the AP to forward mDNS packets to the controller. VLAN visibility at the controller is achieved by APs that forward the mDNS advertisements to the controller. The mDNS packets between the AP and the controller are forwarded through a CAPWAP data tunnel that is similar to mDNS packets from a wireless client. Only CAPWAP v4 tunnels are supported. APs can be in either access port or the trunk port to learn the mDNS packets from the wired side and forward them to the controller."

Has something changed? I've got mDNS working in 7.4... What am I missing? -RIck On 8/13/2013 10:18 AM, Hurt,Trenton W. wrote: I kind of understand that, but if your PI is a vm just take a snapshot of your 1.3 in case you want to rollback to upgrade to 2.0. Although I’m not sure what 2.0 is going to be bringing in it. The ap support isn’t as big as the mdns enhancements and the device profiles that you get in 7.5 in my opinion, but everyone environments/requirements are different. Unfortunately for me apple tv display mirroring has become a huge issue here so I’m pretty much forced to go 7.5 route.

The biggest feature that I see that they added is APs are now able to see and repeat mDNS advertisements. Now you can plug an AppleTV in on any subnet and the wireless system sees and reflects it to all wireless. Very cool. What’s not very cool is the fact that none of my iDevices see the same list of AppleTVs and for the life of me I can’t figure out why or even how. Some devices see the same AppleTVs, some see others, some don’t. Cycling Airplay on the AppleTV doesn’t make a difference. And ideas on how to make this more consistent?
