RocketLinx ES7506 User Guide: 2000529 Rev. F

Configuration Using the Web Interface

IGMP Query

Use this page to configure the IGMP Query feature. Since the ES7506
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.
