Environment : This article applies to Aruba Instant Access Points.
The Aruba mobility controller supports multicast and video optimization features such as IGMP Snooping and Proxy and dynamic multicast optimization.
Aruba Instant does not offer multicast intelligence like the mobility controller or the multicast router does. Instant AP forwards multicast traffic for a given VLAN from the wired network into the wireless network and vice-versa.
Incase, if an administrator wanted to enable multicast to support Bonjour for Apple clients, then he can enable it under Services -> AirGroup tab on WebUI.
Below are the listed steps and the image:
Login to IAP web interface
From the top-right menu, point to "More" and select "Services"
On the "AirGroup" tab.
From the command line:
(Instant Access Point)#configure terminal
(Instant Access Point)(config)# airgroup
(Instant Access Point)(airgroup)# enable-guest-multicast
