Chapter 31 IGMP Snooping Command List
The Internet Group Management Protocol (IGMP) is a L3 protocol used to manage the membership of Internet
Protocol multicast groups. IGMP is used by IP hosts and adjacent multicast routers to establish multicast group
memberships. IGMP snooping is the process of listening to IGMP network traffic. IGMP snooping, as implied by
the name, is a feature that allows a layer 2 switch to "listen in" on the IGMP conversation between hosts and
routers by processing the layer 3 IGMP packets sent in a multicast network.
When IGMP snooping is enabled in a switch it analyzes all IGMP packets between hosts connected to the Switch
and multicast routers in the network. When a switch hears an IGMP report from a host for a given multicast group,
the Switch adds the host's port number to the multicast list for that group. And, when the Switch hears an IGMP
Leave, it removes the host's port from the table entry.
