5-4-6-1. IGMP Snooping

The switch supports IP multicasting. You can enable IGMP via the web management’s configuration screen. In addition, you can view difference multicast groups, VIDs and member ports, and IP multicast addresses that range from 224.0.0.0 through 239.255.255.255.

The Internet Group Management Protocol (IGMP) is an internal protocol of the Internet Protocol (IP) suite. IP manages multicast traffic by using switches, routers, and hosts that support IGMP. Enabling IGMP allows the ports to detect IGMP queries and report packets and manage IP multicast traffic through the switch. IGMP has three fundamental types of message as follows:

	Message	Description
	Query	A message sent from the queryer (IGMP router or switch) asking for a
	Query	response from each host belonging to the multicast group.
	Report	A message sent by a host to the queryer to indicate that the host wants to be
	Report	or is a member of a given group indicated in the report message.
	Leave	A message sent by a host to the queryer to indicate that the host has quit a
	Leave	specific multicast group.
