Configuration procedure: 
Step  Operation  Description 
1 Enable IGMP Snooping 
function 
Required. Enable IGMP Snooping globally on the switch 
and for the port on Multicast→IGMP 
Snooping→Snooping Config and Port Config 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 VLAN→802.1Q 
VLAN 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 
Multicast→IGMP Snooping→Multicast VLAN 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 Multicast→IGMP Snooping→Snooping Config 
page. 
8.2  Application Example for Multicast VLAN  Network Requirements 
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. 
Switch: Port 3 is connected to the router and the packets are transmitted in VLAN3; port 4 is 
connected to user A and the packets are transmitted in VLAN4; port 5 is connected to user B and 
the packets are transmitted in VLAN5. 
User A: Connected to Port 4 of the switch. 
User B: Connected to port 5 of the switch. 
Configure a multicast VLAN, and user A and B receive multicast streams through the multicast 
VLAN.
