[ no ] mvr type { receiver | source }
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.

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. If statically configured as a
member of the MVR VLAN using the switchport allowed vlan command,
the receiver port’s MVR status will be inactive.
IGMP snooping can be used to allow a receiver port to dynamically join
or leave multicast groups sourced through the MVR VLAN. Multicast
groups can also be statically assigned to a receiver port using the mvr
group (Interface Configuration) command.
Also, note that VLAN membership for MVR receiver ports cannot be set
to trunk mode (see the switchport mode command).
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
assigned through the mvr group (Global Configuration) command.
IGMP snooping must be enabled to a allow a subscriber to dynamically
join or leave an MVR group (see the ip igmp snooping command). Note
that only IGMP version 2 or 3 hosts can issue multicast join or leave
messages.

switch.
