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. | ||
|
