Enabling IGMP snoop on a VLAN

Enable IGMP snooping on a VLAN to optimize the multicast data flow for a group within a VLAN to only those that are members of the group that uses IGMP snoop.

About this task

The switch listens to group reports from each port and builds a database of multicast group members for each port. The switch suppresses the reports heard by not forwarding them to other hosts, forcing the members to continuously send their own reports.

The switch relays group membership from the hosts to the multicast routers and forwards queries from multicast routers to all port members of the VLAN. The switch multicasts data only to the participating group members and to the multicast routers within the VLAN.
