mvr port type This command displays or sets MVR port type as a source or receiver.
SYNTAX
mvr port type [port-list] [source | receiver]
port-list - A specific port or a range of ports. (Range: 1-28, or all)
source – Sets the specified ports as an uplink that can send and
receive multicast data for the groups assigned to the MVR VLAN.
Note that the source port must be manually configured as a
member of the MVR VLAN (using the vlan add command).
receiver – Sets the specified ports as subscriber ports that can
receive multicast data sent through the MVR VLAN. Any port
configured as a receiver port will be dynamically added to the MVR
VLAN when it forwards an IGMP report or join message from an
attached host
requesting any of the designated multicast services
supported by the MVR VLAN.
DEFAULT SETTING
All ports are configured as receiver ports.

port-list - A specific port or a range of ports. (Range: 1-28, or all)
enable - Enables immediate leave for specified ports.

COMMAND USAGE
This command configures the switch to immediately remove an interface
from a multicast stream as soon as it receives a leave message for that
group. (This option only applies to an interface configured as an MVR
receiver.)
Just remember that only IGMP version 2 or 3 hosts can issue multicast
leave messages. If a version 1 host is receiving multicast traffic, the switch
can only remove the interface from the multicast stream after the host
responds to a periodic request for a membership report.
