Parameter to enable or disable IGMP snooping on the device. When enabled, the device will examine IGMP packets and set up filters for IGMP ports. 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 have three fundamental types of message as follows: Message Description Query A message sent from the querier (IGMP router or switch) asking for a response from each host belonging to the multicast group. Report A message sent by a host to the querier to indicate that the host wants to be or is a member of a given group indicated in the report message. Leave Group A message sent by a host to the querier to indicate that the host has quit to be a member of a specific multicast group. You can enable IGMP protocol and IGMP Query function. You will see the IGMP snooping information in this section multicast group VID and member port, and IP multicast addresses range from 224.0.0.0 through 239.255.255.255.
