DEFAULT SETTING
MVR is disabled.
No MVR group address is defined.
The default number of contiguous addresses is 0.
MVR VLAN ID is 1.
COMMAND MODE
Global Configuration
COMMAND USAGE
◆ Use the mvr group command to statically configure all multicast group
addresses that will join the MVR VLAN. Any multicast data associated
with an MVR group is sent from all source ports, 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.
◆ 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.
◆ 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.
◆ 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 configured as
members of this VLAN.
EXAMPLE
The following example enables MVR globally, and configures a range of
MVR group addresses:
Console(config)#mvr
Console(config)#mvr group 228.1.23.1 10
Console(config)#
mvr
immediate-leave
This command causes the switch to immediately remove an interface from
a multicast stream as soon as it receives a leave message for that group.
Use the no form to restore the default settings.
