IGMP Configuration
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, report packets, and manage IP multicast
traffic through the switch. IGMP have three fundamental types of message
shown 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 being a member of a specific multicast group.
The switch supports IP multicast. You can enable IGMP protocol via setting
the IGMP Configuration page to see the IGMP snooping information. IP
multicast addresses are in the range of 224.0.0.0 through 239.255.255.255.
 IGMP Protocol: Enable or disable the IGMP protocol.
 IGMP Query: Select the IGMP query function as Enable or Auto to set
