4.8.16 MVR (Multicast VLAN Registration)
The MVR feature enables multicast traffic forwarding on the Multicast VLANs.
â– In a multicast television application, a PC or a network television or a set-top box can receive the multicast
stream.
â– Multiple set-top boxes or PCs can be connected to one subscriber port, which is a switch port configured as
an MVR receiver port. When a subscriber selects a channel, the set-top box or PC sends an IGMP/MLD
report message to Switch A to join the appropriate multicast group address.
â– Uplink ports that send and receive multicast data to and from the multicast VLAN are called MVR source
ports.
It is allowed to create at maximum 8 MVR VLANs with corresponding channel settings for each Multicast VLAN.
There will be totally at maximum 256 group addresses for channel settings.
