IGMP/MLD IP Group Addresses
The IGMP IP Group Addresses page displays the IPv4 group address learned from IGMP
messages.
There might be a difference between information on this page and, for example, information
displayed in the MAC Group Address FDB 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 Group Address FDB page, but two entries on this page.
To query for an IP Multicast group:
1. Click
Configuration > Multicast > IGMP IP Group Addresses
.
2. Enter some or all of following query filter criteria:
•
VLAN ID — Defines the VLAN ID to query.
•
IP Group Address — Defines the Multicast group MAC address or IP address to
query.
•
Source IP Address — Defines the sender address to query.
3. Click Search.
The following fields are displayed for each Multicast group:
•
Dynamic IP Group Type
•
VLAN ID — The VLAN ID.
•
IP Group Address — The Multicast group MAC address or IP address.
•
Source IP Address — The sender address for all of the specified group ports.
•
Included Ports — The list of destination ports for the Multicast stream.
