4.8.14 MVR
The MVR feature enables multicast traffic forwarding on the Multicast VLANs. In a multicast television application, a PC or a
network television or a set-top box can receive the multicast stream. 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. 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 maximun 8
MVR VLANs with corresponding channel settings for each Multicast VLAN. There will be totally at maximun 256 group
addresses for channel settings.
