MVR Configuration

IGMP snooping helps limit multicast traffic when member ports are in the same VLAN; 
however, when ports belong to different VLANs, a copy of the multicast stream is sent to 
each VLAN that has member ports in the multicast group. MVR eliminates the need to 
duplicate the multicast traffic when multicast group member ports belong to different VLANs.

MVR uses a dedicated multicast VLAN to forward multicast traffic over the L2 network. Only 
one MVLAN can be configured per switch, and it is used only for certain multicast traffic, such 
as traffic from an IPTV application, to avoid duplication of multicast streams for clients in 
different VLANs. Clients can dynamically join or leave the mutlicast VLAN without interfering 
with their membership in other VLANs.

MVR, like IGMP Snooping, allows a layer 2 switch to listen to IGMP messages to learn about 
multicast group membership.

From the MVR Configuration link under the Switching tab, you can configure the MVR 
settings.

From the MVR Configuration link, you can access the following links:

Use MVR Running to Enable or Disable the MVR feature. The factory default is 

Disable.

Use MVR multicast to specify the VLAN on which MVR multicast data will be received. 

All source ports belong to this VLAN. The value can be set in a range of 1 to 4093. The 

default value is 1.
