MVR for IPv4
– 709 –
mvr type This command configures an interface as an MVR receiver or source port. Use the
no form to restore the default settings.
Syntax
[no] mvr [domain domain-id] type {receiver | source}
domain-id - An independent multicast domain. (Range: 1-5)
receiver - Configures the interface as a subscriber port that can receive
multicast data.
source - Configures the interface as an uplink port that can send and
receive multicast data for the configured multicast groups.
Default Setting
The port type is not defined.
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
â—† 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.
â—† 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).
â—† 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.
â—† 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
