IGMP Snooping Configuration
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.
Table 189 describes the commands used to configure IGMP Snooping.
