5580 & multicast (bonjour)

Unanswered Question
Jul 8th, 2011

I have just completed an 18AP install at my place of employment and we have run into a slight problem.

The Apple clients on our wireless LAN cannot discover printers through the bonjour protocol.

Am I correct in saying this would be related to either a unicast or multicast issue?

Can someone point me in the correct direction on how to begin configuring either unicast or multicast between the 5508's and other switching devices.

Currently I have the 2 5508's patched into a 3750 (which provides routing) and from that switch on, the other AP's connect from the network.


I have this problem too.

Airprint may not be compatible with IGMP snooping -- I've seen cases where igmp snooping needs to be disabled for reliable service. I'm not sure if Airprint can be configured to participate in IGMP.

if i disable IGMP snooping then it doesn't even show up on the iphones or ipads.. its says printer cannot be found
