The following table describes the labels in this screen.

22.5 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.

Filtering Profile

LABEL

DESCRIPTION

Profile Name

Enter a descriptive name for the profile for identification purposes.

To configure additional rule(s) for a profile that you have already added, enter the profile
name and specify a different IP multicast address range.

Start Address

Type the starting multicast IPv6 address for a range of multicast IPv6 addresses that you
want to belong to the MLD filtering profile.

End Address

Type the ending multicast IPv6 address for a range of IPv6 addresses that you want to
belong to the MLD filtering profile.

If you want to add a single multicast IPv6 address, enter it in both the Start Address and
End Address fields.

Add

Click this to create a new entry.

This saves your changes 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.

Clear

Click Clear to reset the fields to the factory defaults.

Profile Name

This field displays the descriptive name of the profile.

Start Address

This field displays the start of the multicast IPv6 address range.

End Address

This field displays the end of the multicast IPv6 address range.

Delete

To delete the profile(s) and all the accompanying rules, select the profile(s) that you want
to remove in the Delete Profile column, then click the Delete button.

To delete a rule(s) from a profile, select the rule(s) that you want to remove in the Delete
Rule column, then click the Delete button.

Cancel

Click Cancel to clear the Delete Profile/Delete Rule check boxes.
