Igmp Snooping; Igmp Snooping Configuration - D-Link DGS-3312SR Release 3.5 Manual

DGS-3312SR Stackable Gigabit Layer 3 Switch

IGMP Snooping

In order to use IGMP Snooping it must first be enabled for the entire Switch (see Advanced Settings). You may then fine-
tune the settings for each VLAN using the IGMP Snooping Settings window. 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.
