Hello,
We have been successfully using our Aironet 1140 AP in standalone mode with mainly Windows pcs & laptop users, and now, iPads and iPhones.
All seem to connect happily through the 1140.
Recently we have a requirent to be able to use Apple's Airplay. Basically, it is not working through the 1140, it works ok via wired ethernet. Can the 1140 support Airplay? - If yes, what precisely must be enabled/configured? - please be specific as I am very much a greenhorn on configuring this AP.
We have a single Class C network without any Vlans. I understand multicast must be enabled, I can't see where to enable this. I really would appreciate some guidance on getting this working if it is at all possible. Much appreciate your time.
Rgds.

Hello Yahya,
I read through all those links and no matter what I tried it didn't fix it.
However, I suddenly realised I have never upgraded the s/w on these devices. I downloaded the latest 12.4 version and it now works perfectly.
A lesson to all ( and me especially) - make sure your software is up to date......
Thanks for your help
Rgds.

Hi all,
sorry for reactivating this old thread, but I have the exact same problem with two autonomous AP1142N. The hosts involved are all on the same VLAN and subnet, so there should be no routing involved — in fact, whether IGMP snooping is activated or not doesn't make a difference.
The interesting part is that multicast pings from the wireless segment to the wired segment works, but the other way around is blocked at the AP.
If, on a host on the WiFi, I do a simple
ping 224.0.0.251
I get answers from multiple hosts in the wired segment (but only from there). The same ping from a wired host also only receives acknowledgments from the wired hosts.
So it appears as if the hosts on the WiFi are not able to join the multicast group. I've also noticed that many IGMP-related commands on the APs such as
show ip igmp groups
just return "router IGMP command not supported".
Finally there's a post on this forum that seems to imply that Bonjour support was broken in IOS v15 (which I have on the APs):

The configurations look fine from what I also have read on the forums. I just know the v15 has broke the bonjour stuff.
Thanks,
Scott
So all in all, I'm pretty confused. Is there any way I can get Bonjour to work with our APs?
Thanks for any and all feedback, even if it's just to let me know that it won't work.
Cheers,
Dorian

Sounds counter-intuitive, but try disabling IGMP snooping on the AP.
-Edit: just noticed you already tried that! Does any multicast traffic actually work at all over the AP?

Thanks for your reply! Regarding multicast over the AP, I can ping a multicast address from the WiFi and receive answers from hosts on the wired network, but that's it. It seems like the AP doesn't consider any wireless host to be member of any multicast group.
If you need some more detailed testing, I'll gladly perform any diagnostics you'd need, I've also tried some iperf measurements using multicast traffic and had basically the same results.
If it's of any interest, here's the current IGMP snooping configuration (VLAN 99 is a guest network that's completely isolated from the rest, so I doubt it has any influence, but I've included it here for the sake of completeness):
cisco-pro>show ip igmp snooping
