WLC 2106 and iPad Airprint

[Andrew Mouser]

I have been trying to get Airprint to work in our network.  Topology is a 255.255.255.254.x network that has mostly wired with wireless all under the same subnet.  Airprint will not discover printers if on the WLC2106 WiFi network but if the iPad or iPhone is connected to some small Linksys WiFi router, it works.

What should be enabled or disabled on the WLC2106 to get Airprint to work?  I think I've tried everything.

Thanks,

Andrew

Thanks guys for this really useful information, though I have a further question. 

I have a distributed WLC architecture (WLC's in two Datacentres, AP's at remote sites) with all the AP's using H-REAP for our Corporate Network, and a "Guest" network that is tunneled back to a Mobility Anchor that has internet access.  If an "airprint" printer is connected to our guest SSID, do I enable Multicast and Broadcast on the Mobility Anchor or is it required on all the WLC's?

Just wanted to say in 2019, this just helped us solve a major problem we were having with the exact same issue. We had spent HOURS with TAC on this. Never got past the fact-finding phase

Andrew:

I went through almost similar issue with one of customers. (the issue with my customer was about broadcast packets not being sent out from WLC when received although broadcast is enabled. the solution was to enable multicast because if multicast is disabled then broadcast will not work).

You need to enable multicast anyway. But you also may need to enable broadcast.

use those commands:

config network multicast global enable

config network broadcast enable

if first multicast command did not fix it try broadcast as well.

I hope this is giong to fix your issue.

Hey Guys, having similar issues but in my case the wired device  (Sonos PZ90 Multimedia device) is the one sending the broadcast packets  and the Wireless clients are not seeing that traffic. This is only for  initial setup, once the setup is completed (putting the client wired)  the application on the devices work via wireless.

Sonos Client -------------WLC2500----------------SW 3750X Stack---------------------Sonoz PZ90

Ideas anyone?

Thanks...

[Amjad Abdullah]

Do u have the config i stated above done?

config network multicast global enable

config network broadcast enable

If it is done then broadcast should work.

Yes, multicast is working fine, just the initial setup of the device is the one failing...

I access all of my sonos equipment via a 2106 and 2504 without issues having multcast enabled, broadcast enabled, and igmp snooping enabled.

I would also check what's going on with the 3750 stack, there are a lot of people that have issues with higher end switchs/routers over on the sonos forums.

[pcabarga]

Yes, I suspected also the switches, upgraded to the latest IOS version and still same problem. The switches have a very Very basic setup on the switches, and by the way all the devices involved are on the same VLAN. Just to discard I also put the AP's an WLC management on the same VLAN...nada, niente, zip......same problem still....

I think if we collect sniffer traces on the WLC, switch and device ports we can make sure where exactly the broadcast/multicast packets are being stopped. If it is a switch issue it can be further investigated from swtich side.
