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 use the
no form with 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 Mode
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.
• IGMP snooping must be enabled to a allow a subscriber to dynamically join or
leave an MVR group (see ip igmp snooping on page 33-2). Note that only
IGMP version 2 or 3 hosts can issue multicast join or leave messages.
Example
The following example enables MVR globally, and configures a range of MVR group
addresses:
Console(config)#mvr
Console(config)#mvr group 228.1.23.1 10
Console(config)#
