x IGMP Snooping relates to the protocol IGMP. IGMP enables routers to create
lists of devices that are members of multicast groups. A multicast group might
consist of all users that want to see the company yearly meeting on video.
Video is a multicast application. IGMP snooping enables the switch to monitor
the flow of queries from the devices and the routers. IGMP snooping improves
the switches' performance by restricting the flow of multicast packets to only
those switch ports, which have devices receiving the multicast (video).

multicast group(s). It controls how frequently the switch expects to see
information from devices that stay members of multicast groups and process
leaving requests.
