♦ IP Multicast Filtering (IGMP Snooping)
This enables or disables the Switch to intelligently forward
IGMP and multicast packets instead of broadcasting (flooding) them on all ports. This setting also enables
IGMP snooping, which enables the Switch to read IGMP packets being forwarded through the Switch in
order to obtain forwarding information from them (learn which ports contain multicast members).
