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

MAC Multicast
page, but two entries on this page.

Group page opens.
STEP 2 Set the type of snooping group for which to search: IGMP or MLD.
