AirPrint / Bonjour Traffic Not Flowing on Cisco 3560 Switches

[coolguy982]

We are in the process of rolling out iPads to our offices.  As part of this implementation, we need to print from the iPads to our network printers.  Our network printers are mostly HP and Xerox and do not have native Apple AirPrint capabilities.  As such, we have been using the FingerPrint software to share out the network printers as Apple AirPrint printers.  We have a mixture of switches at our offices.  Most offices utilize a 3550 PoE switch.  In these offices the AirPrint traffic is being transferred successfully and everything works great. In the offices which are using 3560 PoE switches, the traffic is never seen at the iPads.  We are using EnGenius EAP300 access points connected into the Cisco switches to provide wireless access to the iPads. Both 3550 and 3560 switches are running iOS 12.2(25). 

Any idea what might be stopping/blocking the AirPrint traffic on the 3560 switches?  Any suggestions would be appreciated!

Your 3550 are they runnint L3 and do they have multicast enabled vs the 3560's? Getting Bonjour to work really good in an enterprise environment is a total pain I had to deal with that and it consumed lot of time.  You can also look into settingup a bonjour gateway here are couple of links that might be helpful:

Thanks for the reply.  Can you tell me the commands to check to see whether L3 is running or if multicast is enabled?  I can't seem to find a clear answer to this.

Hi Scott,

It would be much easier if you post here 3550 and 3560 switches configuration.

Hope it will help.
