L2 Multicast Control
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.
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.
