4-6.13 IGMP Configuration
The Internet Group Management Protocol (IGMP) is an internal protocol of the Internet Protocol (IP). IGMP
Snooping mode allows the switch to forward multicast packets to appropriate ports. The switch will detect
IGMP queries when multicast packets come in and then report back with packets indicating which port is
willing to accept the multicast packets. With this function, network traffic can be limited without unwanted
packets being sent to certain ports. IGMP has three fundamental types of messages 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.
