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 4-231) and switchport native
vlan command (page 4-230), 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 4-299). Note that only
IGMP version 2 or 3 hosts can issue multicast join or leave messages.
• Note that only IGMPv1/v2 multicast report messages or IGMPv2 leave
messages sent by IGMPv1/v2 hosts are supported by the current MVR
standard.
• 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.
Example
The following example enables MVR globally, designates the MVR VLAN as VLAN
1, and configures a range of MVR group addresses:
Console(config)#mvr
Console(config)#mvr vlan 1
Console(config)#mvr group 228.1.23.1 10
Console(config)#
