Igmp Snooping - D-Link DES-6500 - Switch User Manual

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.
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 link in the Configuration folder. 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. Use the IGMP Snooping Group Entry Table to view IGMP Snooping status. To modify
settings, click the Modify button for the VLAN Name entry you want to change.
Use the IGMP Snooping Settings window to view IGMP Snooping settings. To modify the settings, click the Modify button of
the VLAN ID you want to change.
Clicking the Modify button will open the IGMP Snooping Settings menu, shown below:
