Configuring IGMP

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.
