To enable IGMP snooping:
 |
Click on the Enable text box in the Snoop tab, and select true. |
IGMP snooping works only when a multicast router that has been dynamically learned as a Querier exists in the VLAN. Even when IGMP snooping is enabled, if the VLAN does not hear a query from a multicast router, the group reports from the hosts are not processed.
