MVR

MVR ("Multicast VLAN Registration") through which a media server can
transmit a multicast stream in an individual multicast VLAN and in which the
clients receiving the VLAN stream can be located in different VLANs. Clients in
different VLANs can join or leave the multicast group simply by sending an
"IGMP Join Message" or "IGMP Leave Message" to a receiver port. The receiver
port belonging to a multicast groups can receive the multicast stream from the
media server. Without MVR support, the multicast stream from the media server
and subscriber would have to be in the same VLAN.

MVR Mode
• Dynamic Mode
If dynamic mode is enabled in the MVR settings, the "IGMP Report
Message" is transmitted from the receiver port to the source ports of the
multicast router. The multicast router can detect dynamically which
multicast groups are on which interface.
Compatibility Mode
•
If compatibility mode is enabled in the MVR settings, the "IGMP Report
Message" send by the receiver port is not transmitted to the source ports of
the multicast router. The multicast router must be statically configured.
Operating Mode
•
Join Operation
A subscriber sends an "IGMP Report Message" to the switch to join a
respective multicast. The next step depends on whether the "IGMP Report
Message" matches the multicast MAC address configured on the switch. If
it matches, the switch CPU modifies the hardware address table to include
the receiver port and the VLAN as a forwarding destination for the
MVLAN.
Leave Operation
•
A subscriber sends an "IGMP Leave Message" to the switch to leave the
multicast. The switch CPU sends a group-specific "IGMP Query" to the
receiver port of the VLAN. If there is another subscriber in the VLAN, the
subscriber must respond within the maximum response time. If there is no
subscriber, the switch deletes the receiver port.
