There might be a difference between information on this page and, for example,
information displayed in the MAC Group Address page
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.
Set the type of snooping group for which to search: IGMP or MLD.
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.
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 device receives on the IP group address.
A Multicast router (Mrouter) port is a port that connects to a Multicast router. The
device includes the Multicast router port(s) numbers when it forwards the
Multicast streams and IGMP/MLD registration messages. This is required so that
the Multicast routers can, in turn, forward the Multicast streams and propagate the
registration messages to other subnets.
