25.3 MVR Overview

Multicast VLAN Registration (MVR) is designed for applications (such as Media-on-Demand (MoD))
that use multicast traffic across an Ethernet ring-based service provider network.
MVR allows one single multicast VLAN to be shared among different subscriber VLANs on the
network. While isolated in different subscriber VLANs, connected devices can subscribe to and
unsubscribe from the multicast stream in the multicast VLAN. This improves bandwidth utilization
with reduced multicast traffic in the subscriber VLANs and simplifies multicast group management.
MVR only responds to IGMP join and leave control messages from multicast groups that are
configured under MVR. Join and leave reports from other multicast groups are managed by IGMP
snooping.
The following figure shows a network example. The subscriber VLAN (1, 2 and 3) information is
hidden from the streaming media server, S. In addition, the multicast VLAN information is only
visible to the Switch and S.

25.3.1 Types of MVR Ports

In MVR, a source port is a port on the Switch that can send and receive multicast traffic in a
multicast VLAN while a receiver port can only receive multicast traffic. Once configured, the Switch
maintains a forwarding table that matches the multicast stream to the associated multicast group.

DESCRIPTION
Click Add to save the profile to the Switch's run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel
to save your changes to the non-volatile memory when you are done configuring.
Click Clear to clear the fields to the factory defaults.
This field displays the descriptive name of the profile.
This field displays the start of the multicast address range.
This field displays the end of the multicast address range.
To delete the profile(s) and all the accompanying rules, select the profile(s) that you want
