Enterprise and Apple have this love/hate relationship. End users love Apple. IT tends to be hesitant in supporting the awesome features they come with. AirPlay is probably the most requested feature. Cisco didn’t officially support Bonjour and AirPlay until version 7.4 in the Wireless LAN Controller. The latest revisions have improvements in supporting Bonjour and especially in the configuration.
In this post I will discuss configuration on the Cisco WLC version 18.104.22.168. What configuration is needed on your switches and how you can verify Bonjour is working. We’ll get it working for devices on the same subnet and across different subnets, both wired and wireless.
I was able to test this with multiple iPads and a handful of iPhones. With 3rd party software I was able to use my Windows 8 laptop to AirPlay my screen to an Apple TV. No lag or jitter was encountered during my tests. To be fair, I do not have a lot of users hitting the wireless network to really see any performance hits.
Before configuring Bonjour, I performed a wireless site survey and made adjustments to provide proper coverage for connectivity and ensured there was no interference.
Cisco Wireless LAN Controller Requirements
To allow Bonjour to traverse the wireless network there will need to be some features enabled:
- Broadcast forwarding
- IGMP snooping
