Querier Config

Page 155 highlights

The following entries are displayed on this screen:  Multicast VLAN Multicast VLAN: Select Enable/Disable Multicast VLAN feature. 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 IGMP 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 IGMP report message from the member port, it will consider this port is not a member port any more. Dynamic Ports: Router Static Router Ports: Displays the dynamic router ports of the multicast VLAN. Specify 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 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 802.1Q VLAN page. 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. After a multicast VLAN is created, all the MLD packets will be processed only within the multicast VLAN. 8.2.5 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. 145
