The switch forwards multicast traffic destined for multicast groups (that it has learned from IGMP snooping) to ports that are members of that group. The switch discards multicast traffic destined for multicast groups that it does not know. IGMP snooping generates no additional network traffic, allowing you to significantly reduce multicast traffic passing through your switch.
