VLAN ID:  Enter the VLAN ID of the multicast VLAN. 
Router Port Time: 
Specify the aging time of the router port. Within this time, if the 
switch doesn’t receive MLD 
query message from the router port, it 
will consider this port is not a router port any more. 
Member Port Time: 
Specify the aging time of the member port. Within this time, if the 
switch doesn’t receive  MLD 
report message from the member 
port, it will consider this port is not a member port any more. 
Dynamic Router 
Ports: 
Displays the dynamic router ports of the multicast VLAN.     
Static Router Ports: 
Specify the static router port which is mainly used in the network 
with stable topology. 
Note: 
1.  The Multicast VLAN won't take effect unless you first complete the configuration for the 
corresponding VLAN owning the port on the 802.1Q VLAN page. 
2.  The router port should be in the multicast VLAN, otherwise the member ports cannot receive 
multicast streams. 
3.  Configure the link type of the router port in the multicast VLAN as Tagged otherwise all the 
member ports in the multicast VLAN cannot receive multicast streams. 
4.  Before creating a Multicast VLAN, you should enable the MLD snooping function in  9.2.1 
Snooping Config. 
5.  After a multicast VLAN is created, all the MLD packets will be processed only within the 
multicast VLAN. 
Configuration Procedure of Multicast VLAN: 
Step  Operation  Description 
1 
Create VLAN.  Required. On the VLAN  →802.1Q VLAN →VLAN Config 
page, click the Create 
button to create a VLAN. Enter the 
VLAN ID and the description for the VLAN. Meanwhile, 
specify its member ports. 
2 
Enable MLD snooping 
globally. 
Required. On the Multicast →MLD Snooping →Snooping 
Config page, enable the MLD snooping function globally. 
3 
Enable the Multicast VLAN.  Required. On the Multicast →MLD Snooping →Multicast 
VLAN  page, enable the Multicast VLAN 
specify the Multicast VLAN ID 
Step 1. 
9.2.5 Querier Config 
In an IPv6 multicast network that runs MLD, a Layer 3 multicast device works as an MLD querier to 
send out MLD queries and manage the multicast table. But MLD is not supported by the devices in 
Layer 2 network. MLD Snooping Querier can act as an MLD Router in Layer 2 network. It can help 
to create and maintain multicast forwarding table on the switch with the Query messages it 
generates.
