Igmp Snooping Unifi is a feature of UniFi Switches which prevents unnecessary multicast traffic from flooding your network. It blocks multicast traffic by listening to IGMP (Internet Group Multicast Protocol) messages sent between end-hosts and multicast routers. When a host requests to join a multicast group, the switch will then forward multicast traffic for that group only to the ports with hosts that have requested to join. This helps to conserve bandwidth and reduce unnecessary broadcast traffic on the network.
