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:

  1. Click Multicast > IGMP/MLD IP Multicast Group. The IGMP/MLD IP Multicast Group page opens.
  2. Set the type of snooping group for which to search: IGMP or MLD.
  3. Enter some or all of following query filter criteria:
    • Group Address equals to--Defines the Multicast group MAC address or IP address to query.
    • Source Address equals to--Defines the sender address to query.
    • VLAN ID equals to--Defines the VLAN ID to query.
  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.
    • Compatibility Mode--The oldest IGMP/MLD version of registration from the hosts the switch receives on the IP group address.
