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.
