Multicast
Multicast support is enabled in the Cisco 8500 Controller, and its operation is comparable to that of the Cisco
5500 Series Controllers, but with these restrictions:
If all APs on the 8500 Controller are configured in Local mode, Multicast−Multicast will be the
default mode and all features are supported (for example, VideoStream). This scenario is identical to a
5500 Controller.
