Airplay suddenly not working on WLC2504

Hi All,

I have the following setup:

Cisco WLC2504 with 6 APs

Cisco Small Business Switch

We have airplay working with any apple device that could connect to the network on a particular SSID, all of a sudden this has stopped working.  The only change as far as I know is that we originally had 2 Apple TVs hardwired to the network and now we have introduced 3 more but wirelessly.

I have checked and ensured that the following is still correct (as I believe it should be for this to work):

WLC2504 Multicast Setup.PNG

Happy to provide any more information needed, many thanks in advance.

HI Ghir,

Please check:

Under | interfaces |

Do you have an mDNS profile selected?

Also, 239.0.0.0 may be the network address for the network.  Try 239.0.0.11 or something other than 0 for the last octet.

Under the WLAN Advanced tab, do you have mDNS snooping enabled along with the desired profile?

also check this document:

Hi Sandeep,

First of all thanks for getting involved, I have checked and found that the mDNS Profile was not selected, changed this now and applied it.  Unfortunately, I am working remotely so will get a user to check it and see if it works. 

On another note, when refering to the 239.0.0.0 or .11 comment, where do you mean?  On the page that I have shown via the screenshot?

Many thanks,

VIP Purple

HI Ghir,

Thats is related to Multicast address:

Global Multicast and set a multicast adddress

It is recommended that the address be on the private range (239.0.0.0-239.255.255.255, which does not include 239.0.0.x and 239.128.0.x.). It is also important that the multicast IP address be set to a different value on each WLC. You do not want a WLC that speaks to its access points to reach the APs of another WLC.

I think this is ok in your WLC.

Regards

Adding to Sandeeps reply.

When I do multicast on the WLC, I use the WLC address as the mutlicast address.

if the mgmt is 10.128.230.5 my multicast for that WLC is 239.128.230.5.  that way when I do a show ip mroute on the L3/mrouter I can easily correlate the address to the WLC.

HTH,
Steve

Hi Sandeep and Steve,

I have checked and no joy!  Scratching my head on what to do next.  Can include a config if that helps

I have added the output from the mDNS page which shows all the Airplay ATVs on my network.  The WLC can see them but not iPad/iPhones on the wireless network can.

Is it possible that something has been added to the network that is blocking Airplay/Bonjour Protocol?

Many thanks,

Re: Airplay suddenly not working on WLC2504

If you upgraded the WLC code, the recent code versions require AirTunes enabled as a service for AirPlay to work.

Hi Scott,

Still at version 7.4, tried to enable Airtunes but no change???

Would you recommend that i upgrade to 7.5?  Don't understand what has changed?

New Member

Yes, all on the same subnet.

Re: Airplay suddenly not working on WLC2504

Upgrading will not help. Everything is in the same subnet so you don't need multicast. All that's needed for AirPlay to work is AirTunes. Maybe create a new mDNS profile and apply it to the WLAN. Also maybe reboot the WLC just for kicks.

Re: Airplay suddenly not working on WLC2504

This was working correctly on v7.4 and suddenly stopped or did you upgrade?

Hi Scott,

I have not upgraded, it was working correctly at 7.4, we are still at 7.4.  We can see the apple devices (ATVs) offering their services on the mDNS page (please see above).  I have connect another wireless vendor (TP-LINK) and can Airplay as I used to be able to on Cisco.

Thanks again,

Re: Airplay suddenly not working on WLC2504

I don't know what else you can do. AirTunes is the only service that's required for AirPlay to work. If everything is on the same subnet, you don't need multicast for this to work. Just to be clear, your iPads don't see the AppleTV's? This is what you want correct so you can mirror?

Hi Scott,

Correct, iPads do not see AppleTVs.  To add to the problem, when i went to turn on Airtunes the Controller crashed and now is having trouble rebooting.

Re: Airplay suddenly not working on WLC2504

Well maybe the WLC was the issue. If it does come back up, only enable services you need.

Airplay suddenly not working on WLC2504

with mdns snooping enabled, it doesn't matter that ap multicast mode is set to multicast/unicast because bonjour multicast is never sent to ap from wlc and we will not see bonjour multicast on wireless also.

when trying to connect on wlc - debug mdns all enable, see what string is missing and add the same to profile.

also, if both device ie., ATV and ipad on same wlan then disable mdns and enable ap mode to unicast.

Hi all,

Sorry I should have commented sooner.  So..........

We got the controller swapped under the RMA and then I went through the configuration bit by bit.  Managed to get it going under the realisation that all the documents that talk about Bonjour Gateway are referring to Layer 3 services.  Turns out that as Scott Fella was saying I don't need much for Airplay to work.  the final config for a flat layer 2 structure is as follows that works for me:
