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,
specifies the MVR VLAN identifier using the vlan keyword, or permits the use of tagged
multicast traffic using the receiver-group and receiver-vlan attributes. Use the no form
of this command without any keywords to globally disable MVR, the no form with the
group keyword to remove a specific address or range of addresses, the no form with the
vlan keyword restore the default MVR VLAN, the no form with the receiver-group
keyword to remove a specific address, or the no form with the receiver-vlan keyword to
disable this feature.
Syntax
[no] mvr [group ip-address [count] | vlan vlan-id | receiver-group ip-address |
receiver-vlan vlan-id]
• group - Defines a multicast service sent to all attached subscribers.
• 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 - Specifies the VLAN through which MVR multicast data is received. This is
also the VLAN to which all source ports must be assigned. (Range: 1-4094)
• vlan-id - MVR VLAN ID (Range: 1-4094)
• receiver-group - Specifies groups to be managed through the receiver VLAN.
• receiver-vlan - Allows multicast traffic to be forwarded from the specified
receiver VLAN without revealing the identity of the MVR VLAN in tagged frames.
Default Setting
• MVR is disabled.
• No MVR group address is defined.
• The default number of contiguous addresses is 0.
• MVR VLAN ID is 1.

Global Configuration
Command Usage
•Use the mvr group command to statically configure all multicast group addresses
that will join the MVR VLAN. Any multicast data associated 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 can be configured as members of the MVR VLAN using the
switchport allowed vlan command (page 4-247) and switchport native vlan
