5.2.24 IGMP/MLD Snooping
IGMP is the protocol used by IPv4 systems to report their IP multicast group memberships to
neighboring multicast routers. IGMPv3 adds support for "source filtering", that is, the ability for a
system to report interest in receiving packets only from specific source addresses, or from all but
specific source addresses, sent to a particular multicast address.
IGMP is used on
IPv4
networks. To handle multicast management on IPv6 networks,
Multicast
Listener Discovery
(MLD) is used in a similar way by IPv6 systems.
With the switch supporting IP multicast, you can enable IGMP/MLD protocol via this interface.
Destination IP multicast addresses range from 224.0.0.0 to 239.255.255.255.
