Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• A port which is not configured as an MVR receiver or source port can use IGMP snooping to join
or leave multicast groups using the standard rules for multicast filtering.
• Receiver ports can belong to different VLANs, but should not normally be configured as a
member of the MVR VLAN. IGMP snooping can also be used to allow a receiver port to
dynamically join or leave multicast groups not sourced through the MVR VLAN. Also, note that
VLAN membership for MVR receiver ports cannot be set to access mode (see the
switchport
mode command).
• One or more interfaces may be configured as MVR source ports. A source port is able to both
receive and send data for multicast groups which it has joined through the MVR protocol or
which have been assigned through the
mvr vlan group command.
• Only IGMP version 2 or 3 hosts can issue multicast join or leave messages. If MVR must be
configured for an IGMP version 1 host, the multicast groups must be statically assigned using
the
mvr vlan group command.
Example
The following configures one source port and several receiver ports on the switch.
Console(config)#interface ethernet 1/5
Console(config-if)#mvr domain 1 type source
Console(config-if)#exit
Console(config)#interface ethernet 1/6
Console(config-if)#mvr domain 1 type receiver
Console(config-if)#exit
Console(config)#interface ethernet 1/7
Console(config-if)#mvr domain 1 type receiver
Console(config-if)#
mvr vlan group
This command statically binds a multicast group to a port which will receive long-term multicast
streams associated with a stable set of hosts. Use the no form to restore the default settings.
Syntax
[no] mvr [domain domain-id] vlan vlan-id group ip-address
domain-id - An independent multicast domain. (Range: 1-5)
vlan-id - Receiver VLAN to which the specified multicast traffic is flooded. (Range: 1-4093)
group - Defines a multicast service sent to the selected port.
ip-address - Statically configures an interface to receive multicast traffic from the IPv4
address specified for an MVR multicast group. (Range: 224.0.1.0 - 239.255.255.255)
Default Setting
No receiver port is a member of any configured multicast group.
