8Go to Configuration > MAC Table to disable MAC address learning on the intermediate and destination ports so that the Switch will NOT filter or forward a frame based on the frame’s destination MAC address, or even drop the frame whose MAC address is not in the MAC address table on these ports.
5.11How to Use IGMP Snooping to Reduce Multicast Traffic Passing through your Switch
The Switch can passively snoop on IGMP packets transferred between IP multicast routers/switches and IP multicast hosts to learn the IP multicast group membership. It checks IGMP packets passing through it, picks out the group registration information, and configures multicasting accordingly.
IGMP snooping allows the Switch to learn multicast groups without you having to manually configure them.
The Switch forwards multicast traffic destined for multicast groups (that it has learned from IGMP snooping or that you have manually configured) to ports that are members of that group. IGMP snooping generates no additional network traffic, allowing you to significantly reduce multicast traffic passing through your Switch.
The Switch can perform IGMP snooping on up to 32 VLANs. You can configure the Switch to automatically learn multicast group membership of any VLANs.
