Multicast VLAN Registration Commands
4-305
4
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.
• IGMP snooping must be enabled to a allow a subscriber to dynamically join or
leave an MVR group (see ip igmp snooping on page 4-288). Note that only
IGMP version 2 or 3 hosts can issue multicast join or leave messages.
Example
The following example enables MVR globally, and configures a range of MVR group
addresses:
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.
• 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.
