Hi all , thanks for all replies Seemingly after i connected a laptop with wireshark , there seem a lot of broadcast which reach as well unused ports Bandwidth supposed to be 5M for each stream requested , so is it possibly CPE ? We have configured IGMP quierer on the Core Switch

What about limitation on how much of the link can be used for multicast ? Can you try adding incremental streams in smaller amounts to find at what point you have too much traffic ? Have you graphed the usage on the link to verify that the amount of bandwidth being used is indeed what you think it might be ? There are about 101 different reasons it could be performing badly, we're sort of just throwing suggestions out there. regards,Tony.
