Manage multicast traffic with IGMP snooping
Internet Group Management Protocol (IGMP) snooping allows a switch to forward
multicast traffic intelligently on the switch. Multicast IP traffic is traffic that is destined to
a host group. Host groups are identified by class D IP addresses, which range from
224.0.0.0 to 239.255.255.255. Based on the IGMP query and report messages, the
switch forwards traffic only to the ports that request the multicast traffic. This feature
prevents the switch from broadcasting the traffic to all ports and possibly affecting
network performance.
The switch maintains a map that shows which links need which IP multicast streams. The
switch forwards multicast traffic only to the links that requested them and cuts multicast
traffic from links that do not contain a multicast listener. Essentially, IGMP snooping
helps optimize multicast performance at Layer 2 and is especially useful for
bandwidth-intensive IP multicast applications such as IPTV.
