Description (partial)


A  single 3750 running 12.2(52)SE causing a 2-7 second delay for a multicast application.


When the video from one of 9 cameras is maximized on the display and the other 8 cameras leave their respective groups and are pruned on the router. When the one camer that was maximized is minimised again, the 8 cameras send a join to their respective multicast groups and this is when there is a 3-7 second delay for some of the cameras.
