The Multicast Forwarding Database IGMP Snooping Table page displays the entries in the multicast forwarding database (MFDB) that were added because they were discovered by the IGMP (Internet Group Management Protocol) snooping feature. IGMP snooping allows the device to dynamically add or remove ports from IPv4 multicast groups by listening to IGMP join and leave requests.
To access this page, click Switching > Multicast Forwarding Database > IGMP Snooping in the navigation menu.
