17 IGMP COMMANDS
This switch uses IGMP (Internet Group Management Protocol) to query for
any attached hosts that want to receive a specific multicast service. It
identifies the ports containing hosts requesting a service and sends data
out to those ports only. It then propagates the service request up to any
neighboring multicast switch/router to ensure that it will continue to
receive the multicast service.
This section describes the commands used to configure IGMP snooping,
query, throttling, and filtering.
