Multicast Vlan Registration - AMX NXA-ENET8-2POE Operation/Reference Manual

Multicast VLAN Registration

Use the MVR Configuration page to enable MVR globally on the switch, select the VLAN that will serve as
the sole channel for common multicast streams supported by the service provider, and to configure each
interface that participates in the MVR protocol as a source port or receiver port.

Multicast VLAN Registration (MVR) is a protocol that controls access to a single network-wide VLAN most
commonly used for transmitting multicast traffic (such as television channels or video-on-demand) across a
service provider's network. Any multicast traffic entering an MVR VLAN is sent to all attached subscribers.

When MVR is enabled on the switch, any multicast data associated with an MVR
group is sent from all designated source ports, to all receiver ports that have regis-
tered to receive data from that multicast group. (Default: Disabled)
Identifier of the VLAN that serves as the channel for streaming multicast services
using MVR. MVR source ports should be configured as members of the MVR
VLAN, but MVR receiver ports should not be manually configured as members of
this VLAN. (Default: 100)
Port identifier.
Sets the MVR operational mode for any port. MVR must also be globally enabled
on the switch for this setting to take effect. MVR only needs to be enabled on a
receiver port if there are subscribers receiving multicast traffic from one of the
MVR groups. (Default: Disabled)
The following interface types are supported:
Source - An uplink port 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 (see "Assigning Ports to VLANs" on
page 161).
Receiver - A subscriber port 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.
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 peri-
odic request for a membership report.
