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 Usage
IGMP snooping and MVR share a maximum number of 255 groups. Any multicast
streams received in excess of this limitation will be flooded to all ports in the
associated 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. (Running status is true as long as MVR Status is
enabled, and the specified MVR VLAN exists.)
• MVR VLAN – Identifier of the VLAN that serves as the channel for streaming
multicast services using MVR. MVR source ports should be configured as
members of the MVR VLAN (see "Adding Static Members to VLANs (VLAN Index)"
on page 3-214), but MVR receiver ports should not be manually configured as
members of this VLAN. (Range: 1-4094; Default: 1)
• MVR Group IP – IP address for an MVR multicast group. (Range: 224.0.1.0 -
239.255.255.255; Default: no groups are assigned to the MVR VLAN)
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.
• Count – The number of contiguous MVR group addresses. (Range: 1-255;
Default: 0)
