IGMP/MLD Snooping IP Multicast Group
The IGMP/MLD Snooping IP Multicast Group page displays the IPv4 and IPv6
group addresses learned from IGMP/MLD messages.
There might be a difference between information on this page and information on
the MAC Group Address page
.
The following is an example: assume that the
system filters according to MAC-based groups and a port requested to join the
following Multicast groups 224.1.1.1 and 225.1.1.1, and 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.

STEP 1 Click Multicast > IGMP/MLD Snooping IP Multicast Group.
