mvr (Global Configuration)
This command enables Multicast VLAN Registration (MVR) globally on the switch,
statically configures MVR multicast group IP address(es) using the group keyword,
or specifies the MVR VLAN identifier using the vlan keyword. Use the no form of
this command without any keywords to globally disable MVR. Use the no form with
the group keyword to remove a specific address or range of addresses, or the vlan
keyword restore the default MVR VLAN.
Syntax
[no] mvr [group ip-address [count] | vlan vlan-id]
• ip-address - IP address for an MVR multicast group.
(Range: 224.0.1.0 - 239.255.255.255)
• count - The number of contiguous MVR group addresses. (Range: 1-255)
• vlan-id - MVR VLAN ID (Range: 1-4094)
Default Setting
• MVR is disabled.
• No MVR group address is defined.
• The default number of contiguous addresses is 0.
• MVR VLAN ID is 1.

Command Usage
•Use the mvr group command to statically configure all multicast group
addresses that will join an MVR VLAN. Any multicast data associated with an
MVR group is sent from all source ports, and to all receiver ports that have
registered to receive data from that multicast group.
• The IP address range from 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.
• MVR source ports should be configured as members of the MVR VLAN using
the switchport allowed vlan command (page 4-200) and switchport native
vlan command (page 4-199), but MVR receiver ports should not be statically
configured as members of this VLAN.
• IGMP snooping must be enabled to a allow a subscriber to dynamically join or
leave an MVR group (see ip igmp snooping on page 4-253). Note that only
