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:
- Click Multicast > IGMP/MLD IP Multicast Group. The IGMP/MLD IP Multicast Group page opens.
- Set the type of snooping group for which to search: IGMP or MLD.
- Enter some or all of following query filter criteria:
- 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.
