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 and
switchport native vlan command, 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). 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)#
mvr (Interface Configuration)
This command configures an interface as an MVR receiver or source port using the type keyword, enables immediate leave
capability using the immediate keyword, or configures an interface as a static member of the MVR VLAN using the group
keyword. Use the no form to restore the

Syntax
[no] mvr {type {receiver | source} | immediate | group ip-address}
receiver -Configures the interface as a subscriber port that can receive multicast data.
source - Configure the interface as an uplink port that can send and receive multicast data for the configured multicast
groups.
immediate - Configures the switch to immediately remove an interface from a multicast stream as soon as it receives a
leave message for that group.
ip-address - Statically configures an interface to receive multicast traffic from the IP address specified for an MVR
multicast group. (Range: 224.0.1.0 -239.255.255.255)
