APPLETV and mDNS - Turn OFF mDNS it works, Turn it on it doesn´t?!?!?!?
I´m having a strange morning. We switched from 7.2.x code to 18.104.22.168 on our 5508 WLC. And Today I get a call that the apple tv´s aren´t visible any more.
Quick check into the MDNS profiles, I see each and every one. Quick check on my iphone to my test appletv - that works too. But it is the only ATV I can actually see.
- I can only see the atv when it is connected to the same Accesspoint, if I roam it vanishes.
- If I turn OFF the MDNS Settings - I see every atv in the building!!!
I configured everything according to: http://www.cisco.com/c/en/us/td/docs/wireless/technology/bonjour/Bonjour74.pdf but somehow it is not working.
(yes the mDNS global is enabled in the tests ;) )
I can see the ATV´s on the WLC:
When it is enabled I can only see the Apple tv that is connected wirelessly to the same AP I´m connected to! So none of the wired devices!
I have enabled the DNS Snooping in the advanced settings for the WLAN. I have also found an extra MDNS Snooping for the Interfaces itself, which wasn´t activated. But activating it, didn´t help a thing. I also tried deactivating the VLAN Multicast feature that was needed in 7.2.x but also to no avail.
HELP! Any Idea what might be running amok here? Everything was working without a hitch in 7.2.x and I thought the 22.214.171.124 would be a blast, because easier, better and such :D Thanks alot for your help!
o.k. thats abit stupid. I had a brain freeze. But just to follow up on this:
If your MDNS Profile that is used for the snooping DOESN´T have the airtunes part included. It won´t work. Just because the general option is choosen, doesn´t do diddly swat for the wlan itself. Guess thats an error I just had to make ;)
