IGMP Snooping Settings
In order to use IGMP Snooping it must first be enabled for the entire Switch under IGMP Global Settings at the top of
the window. You may then fine-tune the settings for each VLAN by clicking the corresponding
Edit
button. 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.
