IGMP snooping

This function monitors whether to join a multicast group.
Internet Group Management Protocol (IGMP) snooping is a filtering function to relay
multicast data only to the required switch port. As shown in
does not support IGMP snooping broadcasts multicast stream to all ports. For a
switch that supports IGMP snooping, destinations to which specific multicast data is
relayed can be restricted to a specific switch port. The GSWB can enable or disable
this function.
IGMP snooping prevents multicast data from being broadcast, thereby optimizing the
network.
