groups within an 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 32-10).
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.
IGMP snooping must be enabled to a allow a subscriber to
dynamically join or leave an MVR group (see ip igmp snooping on
page 35-2). Note that only IGMP version 2 or 3 hosts can issue
multicast join or leave messages.
Example
The following configures one source port and several receiver ports on the
switch, enables immediate leave on one of the receiver ports, and statically
assigns a multicast group to another receiver port:
Console(config)#interface ethernet 1/5
Console(config-if)#mvr type source
Console(config-if)#exit
Console(config)#interface ethernet 1/6
Console(config-if)#mvr type receiver
Console(config-if)#mvr immediate
Console(config-if)#exit
Console(config)#interface ethernet 1/7
Console(config-if)#mvr type receiver
Console(config-if)#mvr group 225.0.0.5
Console(config-if)#
