MVR
The MVR feature enables multicast traffic forwarding on the Multicast VLAN. In a multicast television
application, a PC or a television with 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 join message to Switch A to join the
appropriate multicast. Uplink ports that send and receive multicast data to and from the multicast VLAN are
called MVR source ports.
