Multicast Filtering | IGMP Query Page
Use this page to configure the IGMP Query feature. Since the router can only be configured by member ports
of the management VLAN, IGMP Query can only be enabled on the management VLAN.
If you want to run IGMP Snooping feature in several VLANs, you should check whether each VLAN has its
own IGMP Querier first. The IGMP querier periodically sends query packets to all end-stations on the LANs
