Multicast transmission problem via Fortiswitch

[Chris77]

For many days I have a big problems with manage unwanted traffic, connected with multicast on Fortiswitch. 

The all of packets come from LG tv screens and caused switch hanging what is not registered on other vendor like DCN or TP Link. According to your firt suggestion, our switch has been upgreaded to the newest SW but it did not have positive impact on transmission (IGMP traffic has been turned on as well). Let me know if you have similar problems and how to solve this problem.

Hi, 

please enabled the IGMP snooping to identified the multicast group and prevent unnecessary multicast traffic floods.
if the switch is layer3 device or manageable switch the configure ACL to drops the packet.
Also, check for switch certain model have to avoid the multicast unwanted
