IGMP Query

Use this page to configure the IGMP Query feature. Since the ES8509-XT can only be configured by member
ports of the management VLAN, the IGMP Query can only be enabled on the management VLAN. If you want
to run IGMP Snooping feature in several VLANs, first check to see whether each VLAN has its own IGMP
Querier.
The IGMP querier periodically sends query packets to all end-stations on the LANs or VLANs that are
connected to it. For networks with more than one IGMP querier, a switch with the lowest IP address becomes
the IGMP querier.
