4.10 MVR
Multicast VLAN Registration protocol (MVR) allows a media server to transmit multicast stream in a single multicast VLAN
when 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 or Leave message to a receiver port. The receiver port that
belongs to one of the multicast groups can receive multicast stream from the media server.
MVR further isolates users who are not intended to receive multicast traffic and hence provide data security by VLAN
segregation that allows only multicast traffic into other VLANs to which the subscribers belong. Even though common
multicast streams are passed onto different VLAN groups from the MVR VLAN, users in different IEEE 802.1Q or private
VLANs cannot exchange any information (except through upper-level routing services).
The “MVR” menu contains the following sub menus.
4.10.1 Configuration
MVR Configurations
MVR Mode: Enable or disable MVR feature globally on this device. Any multicast data from source ports will be sent to
associated receiver ports registered in the table. By default, MVR feature is turned off.
VLAN Interface Setting
MVR ID: Specify multicast VLAN ID. Please note that MVR source ports are not recommended to be used as management
VLAN ports. MVR source ports should be configured as members of the MVR VLAN, but MVR receiver ports should not be
manually configured as members of this VLAN.
MVR Name: Optionally specify a user-defined name for this multicast VLAN. The maximum length of the MVR name
string is 32. Both alphabets and numbers are allowed for use.
