This switch uses IGMP (Internet Group Management Protocol) to check 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.

Table 151: Multicast Filtering Commands

Command Group Function
IGMP Snooping Configures multicast groups via IGMP snooping or static

multicast traffic to the attached VLANs
IGMP Filtering and Configures IGMP filtering and throttling
