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.
