MVR
MVR refers to Multicast VLAN Registration that enables a media server to transmit
multicast stream in a single multicast VLAN while clients receiving multicast VLAN stream
can reside in different VLANs. Clients in different VLANs intend to join or leave the
multicast group simply by sending the IGMP Join/leave message to a receiver port. The
receiver port belonging to one of the multicast groups can receive multicast stream from
media server. Without support of MVR, the Multicast stream from media server and
subscriber must reside in the same VLAN.
 Source ports : The Stream source ports.
 Receiver ports : The Client ports.
 Tagged ports : Configure the tagged ports for source ports or receiver ports.
MVR Mode
 Dynamic Mode:
If we select the dynamic mode in MVR setting, IGMP report message transmitted
from the receiver port will be forwarded to a multicast router through its source
port. Multicast router knows which multicast groups exist on which interface
dynamically.
 Compatible mode:
If we select the dynamic mode in MVR setting, IGMP report message transmitted
from the receiver port will not be transmitted to a multicast router.
Operation Mode
 Join Operation:
A subscriber sends an IGMP report message to the switch to join the appropriate
multicast. The next depends on whether the IGMP report matches the switch
configured multicast MAC address. If it matches, the switch CPU modifies the
hardware address table to include this receiver port and VLAN as a forwarding
destination of MVLAN.
 Leave Operation:
Subscriber sends an IGMP leave message to the switch to leave the multicast. The
switch CPU sends an IGMP group-specific query through the receiver port VLAN. If
there is another subscriber in the VLAN, subscriber must respond within the max
response time. If there is no subscriber, the switch would eliminate this receiver
port.
 Immediate Leave Operation:
Subscriber sends an IGMP leave message to the switch to leave the multicast.
Subscribers do not need to wait for the switch CPU to send an IGMP group-specific
query through the receiver port VLAN. The switch will immediately eliminate this
receiver port.
