Use the Multicast > MVR (Configure Interface) page to configure each
interface that participates in the MVR protocol as a source port or receiver
port. If you are sure that only one subscriber attached to an interface is
receiving multicast services, you can enable the immediate leave function.

◆ A port configured as an MVR receiver or source port can join or leave
multicast groups configured under MVR. However, note that these ports
can also use IGMP snooping to join or leave any other 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. MVR allows a receiver port
to dynamically join or leave multicast groups within an MVR VLAN.
Multicast groups can also be statically assigned to a receiver port (see
"Assigning Static MVR Multicast Groups to Interfaces" on page 564 ).
Receiver ports should not be statically configured as a member of the
MVR VLAN. If so configured, its MVR status will be inactive.
◆ One or more interfaces may be configured as MVR source ports. A
source port is able to both receive and send data for configured MVR
groups or for groups which have been statically assigned (see
"Assigning Static MVR Multicast Groups to Interfaces" on page 564 ).
All source ports must belong to the MVR VLAN.
Subscribers should not be directly connected to source ports.
◆ 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 query message to the
receiver port and waiting for a response to determine if there are any
