1. The router port should be in the multicast VLAN, otherwise the member ports cannot receive
multicast streams.
2. The Multicast VLAN won't take effect unless you first complete the configuration for the
corresponding VLAN owning the port on the :2403S"XNCP"page.
3. It is recommended to choose GENERAL as the link type of the member ports in the multicast
VLAN.
4. Configure the link type of the router port in the multicast VLAN as TRUNK or configure the
egress rule as TAG and the link type as GENERAL otherwise all the member ports in the
multicast VLAN cannot receive multicast streams.
5. After a multicast VLAN is created, all the IGMP packets will be processed only within the
multicast VLAN.

1 Enable IGMP Snooping
function
Required. Enable IGMP Snooping globally on the switch
and for the port on Ownvkecuv→KIOR"
Upqqrkpi→Upqqrkpi"Eqphki"and"Rqtv"Eqphki"page.
2 Create a multicast VLAN Required. Create a multicast VLAN and add all the member
ports and router ports to the VLAN on the XNCP→:2403S"
XNCP page.
Configure the link type of the member ports as
GENERAL.
Configure the link type of the router ports as TRUNK or
configure the egress rule as tagged GENERAL.
3 Configure parameters for
multicast VLAN
Optional. Enable and configure a multicast VLAN on the
Ownvkecuv→KIOR"Upqqrkpi→Ownvkecuv"XNCP"page.
It is recommended to keep the default time parameters.
4 Look over the configuration If it is successfully configured, the VLAN ID of the multicast
VLAN will be displayed in the IGMP Snooping Status table
on the Ownvkecuv→KIOR" Upqqrkpi→Upqqrkpi" Eqphki"
page.
Application Example for Multicast VLAN:
" Pgvyqtm"Tgswktgogpvu"
Multicast source sends multicast streams via the router, and the streams are transmitted to user A
and user B through the switch.
Router: Its WAN port is connected to the multicast source; its LAN port is connected to the switch.
The multicast packets are transmitted in VLAN3.
