Description (partial)

Multicast VideoStream will eventually fail because IGMP snooping appears to timeout on WPA2 SSID.  Problem not seen with open SSID.  Seen with -> on 5500 and 8500 controller with AP3700.

Clients will be subscribed to the multicast group and shown correctly on the controller, then eventually the entire group will not show up as being snooped under monitor -> multicast, while multicast clients on the wired network will continue to stream.

It appears all IGMP and MLD snooping entries eventually timeout from the controller.

Using Videostream (aka Mediastream).
