hello, we have a working wireless network managed by a 5508 WLC and nearly a hundred AP in different buildings. We want to integrate several apple-tv in different WLAN. We enable global multicast mode and igmp snooping on the WLC. When clients connect to these wlan airplay functionnality operates for 2 or 3 minutes max and after the airplay icon disappears on iDevices. If i want airplay to work again i need to reboot the Apple-TV but again it can't work for more than 2-3 minutes. Any ideas why it doesn't work
