Configuring Multicast Forwarding Querying IGMP/MLD IP Multicast Group 15 Querying IGMP/MLD IP Multicast Group The IGMP/MLD IP Multicast Group page displays the IPv4 and IPv6 group address learned from IGMP/MLD messages. There might be a difference between information on this page and, for example, information displayed in the MAC Group Address page. Assuming that the system is in MAC-based groups and a port that requested to join the following Multicast groups 224.1.1.1 and 225.1.1.1, both are mapped to the same MAC Multicast address 01:00:5e:01:01:01. In this case, there is a single entry in the MAC Multicast page, but two entries on this page. To query for a IP Multicast group: STEP 1 Click Multicast > IGMP/MLD IP Multicast Group. The IGMP/MLD IP Multicast Group page opens. STEP 2 Set the type of snooping group for which to search: IGMP or MLD.
