IGMP snooping is the process of listening to Internet Group Management Protocol (IGMP)
network traffic. The feature allows a network switch to listen in on the IGMP conversation
between hosts and routers. By listening to these conversations the switch maintains a map of
which links need which IP multicast streams. Multicasts may be filtered from the links which
do not need them and thus controls which ports receive specific multicast traffic.
