To display the following form, select Layer 3 > IGMP > IGMP Snooping (click the underlined text, not the folder).
Internet Group Management Protocol (IGMP) is used by IP Multicast routers to learn about the existence of host
group members on their directly attached subnet (see RFC 2236).
IGMP Snooping allows the switch to forward multicast traffic only to those ports that request it. IGMP Snooping
prevents multicast traffic from being flooded to all ports. The switch learns which server hosts are interested in
receiving multicast traffic, and forwards it only to ports connected to those servers.
