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 default settings.
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.
•group - Defines a multicast service sent to the selected port.
•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)
Default Setting
• The port type is not defined.
• Immediate leave is disabled.
• No receiver port is a member of any configured multicast group.
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 be configured as
a member of the MVR VLAN. IGMP snooping can be used to allow a receiver
port to dynamically join or leave multicast groups within the MVR VLAN.
Multicast groups can also be statically assigned to a receiver port using the
group keyword. However, if a receiver port is statically configured as a
member of an MVR VLAN, its status will be inactive. Also, note that VLAN
membership for MVR receiver ports cannot be set to trunk mode (see the
switchport mode command on page 4-223).
• 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 IGMP snooping or which have been statically assigned using
the group keyword.
• 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.
