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.
To query for a IP Multicast group:
STEP 1 Click Multicast > IGMP/MLD Snooping IP Multicast Group.
STEP 2 Set the type of snooping group for which to search: IGMP or MLD.
STEP 3 Enter some or all of following query filter criteria:
• Group Address equals to—Defines the Multicast group MAC address or IP address to

• VLAN ID equals to—Defines the VLAN ID to query.
STEP 4 Click Go. The following fields are displayed for each Multicast group:
• VLAN—The VLAN ID.
• Group Address—The Multicast group MAC address or IP address.
• Source Address—The sender address for all of the specified group ports.
• Included Ports—The list of destination ports for the Multicast stream.
• Excluded Ports—The list of ports not included in the group.

the device receives on the IP group address.
