ProSafe M5300 Switch 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: • Basic on page 173 • Advanced on page 174 Basic From the Basic link, you can access the following pages: • MVR Configuration on page 173 MVR Configuration To display the MVR Configuration page, click Switching > MVR > Basic > MVR Configuration.
