Multicast groups can be statically assigned to a receiver port using this
command.
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.

The following statically assigns a multicast group to a receiver port:
Console(config)#interface ethernet 1/7
Console(config-if)#mvr type receiver
Console(config-if)#mvr vlan 3 group 225.0.0.5
Console(config-if)#
mvr immediate
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.

This option only applies to an interface configured as an MVR receiver
using the mvr type command).
Immediate leave applies only to receiver ports. When enabled, the
receiver port is immediately removed from the multicast group
identified in the leave message. When immediate leave is disabled, the
switch follows the standard rules by sending a group-specific query to
the receiver port and waiting for a response to determine if there are
any remaining subscribers for that multicast group before removing the
port from the group list.
Using immediate leave can speed up leave latency, but should only be
enabled on a port attached to one multicast subscriber to avoid
