IGMP

Internet Group Management Protocol (IGMP) snooping allows the Switch to recognize IGMP queries and reports sent
between network stations or devices and an IGMP host. When enabled for IGMP snooping, the Switch can open or close a
port to a specific device based on IGMP messages passing through the Switch.
In order to use IGMP Snooping it must first be enabled for the entire Switch on the Switch Information (Advanced
Settings) window (Configuration > Advanced Settings). You may then fine-tune the settings for each VLAN by clicking
the IGMP Snooping link in the Configuration folder. When enabled for IGMP snooping, the Switch can open or close a
port to a specific multicast group member based on IGMP messages sent from the device to the IGMP host or vice versa.
The Switch monitors IGMP messages and discontinues forwarding multicast packets when there are no longer hosts
requesting that they continue.
