4.18 IGMP
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 in here. You will see the IGMP snooping
information in this section -- difference multicast group VID and member port, and IP multicast addresses
range from 224.0.0.0 through 239.255.255.255.
[NOTE] Remember to execute the "Save Configuration" action, otherwise the new configuration will lose
when the switch power off.
