IGMP Snooping

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.

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.
