D-Link DIS-200G-12PS [61/88] L2 multicast control

DIS-200G Series Industrial Gigabit Ethernet Smart Managed Switch

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.
