Airserver multicast mDNS problem

[DAVID THORNTON]

I have WLC 2504 running     7.4.100.0 with a single 1242AG AP

single wireless SSID on the WLC

an Apple AIRSERVER and an IPAD which should be able to do mirroring to show ipad screen on the pc

they have IPs in same subnet and have base connectivity

it just wont work! the ipad never sees the airplay server option come up

BUT

if i move these 2 systems to a cisco autonomous AP. or another commodity wireless LAN and have the 2 systems (pc/ipad) in same subnet it works

if i have the pc on wired and the ipad (wireless obviously) this work on the autonomous or commodity AP fine

so there is something "different" about using the WLC/LWAP right?

i have tried with and without the various multicast options enabled etc

please can anyone advise or help?

many thanks

dave

Since you are using 7.4.x following guides will be useful. You have to configure mDNS feature correctly if you want to get this working.

This is how I configured it in my environment (AppleTV on wried & clients are on wireless), It may help you as well

thank you both for helping me and for the pointers.

I have a config (attached)

I have this update to the case:-

laptop and iphone on same wireless LAN  (interface3) wireless LANcalled clients34

With the command

config mdns snooping DISable

i can see the Airserver from the iPAD and it works (WITHIN) the wireless WLAN i.e. both on same WLAN and IP subnet

if i issue

config mdns snooping ENable

the

Airserver disappears and wont work

it comes back as soon as i disable the mdns snooping

this is consistently reproducible

any ideas welcomed

it never works between WLANs (so far!)
