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:
STEP 1

—Defines the sender address to query.
•

—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

Defining Multicast Router Ports
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.
