Configuring the Switch
3-212
General Configuration Guidelines for MVR
1. Enable MVR globally on the switch, select the MVR VLAN, and add the multicast
groups that will stream traffic to attached hosts (see “Configuring Global MVR
Settings” on page 3-212).
2. Set the interfaces that will join the MVR as source ports or receiver ports (see
“Configuring MVR Interfaces” on page 3-216).
3. Enable IGMP Snooping to a allow a subscriber to dynamically join or leave an
MVR group (see “Configuring IGMP Snooping and Query Parameters” on
page 3-204). Note that only IGMP version 2 or 3 hosts can issue multicast join or
leave messages.
4. For multicast streams that will run for a long term and be associated with a stable
set of hosts, you can statically bind the multicast group to the participating
interfaces (see “Assigning Static Multicast Groups to Interfaces” on page 3-217).
Configuring Global MVR Settings
The global settings for Multicast VLAN Registration (MVR) include enabling or
disabling MVR for the switch, selecting the VLAN that will serve as the sole channel
for common multicast streams supported by the service provider, and assigning the
multicast group address for each of these services to the MVR VLAN.
Command Attributes
• MVR Status – When MVR is enabled on the switch, any multicast data associated
with an MVR group is sent from all designated source ports, and to all receiver
ports that have registered to receive data from that multicast group.
(Default: Disabled)
• MVR Running Status – Indicates whether or not all necessary conditions in the
MVR environment are satisfied.
• MVR VLAN – Identifier of the VLAN that serves as the channel for streaming
multicast services using MVR. (Range: 1-4094; Default: 1)
• MVR Group IP – IP address for an MVR multicast group. The IP address range of
224.0.0.0 to 239.255.255.255 is used for multicast streams. MVR group addresses
cannot fall within the reserved IP multicast address range of 224.0.0.x. (Range:
224.0.1.0 - 239.255.255.255; Default: no groups are assigned to the MVR VLAN)
• Count – Number of contiguous MVR group addresses. (Range: 1-255; Default: 0)
