Chapter 21 Multicast
Without IGMP snooping, multicast traffic is treated in the same manner as broadcast traffic, you can configure the switch to forward or discard unknown multicast group traffic. With IGMP snooping, group multicast traffic is only forwarded 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.
