Static Router Ports: Select the desired port as the static router port which is mainly used in the network with stable topology. Note: 1. The router port should be in the multicast VLAN, otherwise the member ports can not 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 802.1Q VLAN 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 can not receive multicast streams. 5. After a multicast VLAN is created, all the IGMP packets will be processed only within the multicast VLAN. Configuration procedure: Step Operation Description 1 Enable IGMP Snooping Required. Enable IGMP Snooping globally on the switch function 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 Optional. Enable and configure a multicast VLAN on the multicast VLAN 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. 9.1.5 Querier Config In an IP multicast network that runs IGMP, a Layer 3 multicast device works as an IGMP querier to send IGMP queries and manage the multicast table. But IGMP is not supported by the devices in Layer 2 network. IGMP Snooping Querier can act as an IGMP Router in Layer 2 network. It can help to create and maintain multicast forwarding table on the switch with the Query messages it generates.
