IGMP Querier
The IGMP querier function can be enabled to query your network for group
information at a specified time interval. The configuration options available for
IGMP querier depend on whether VLANs are enabled on your network.
• If you plan to use VLANs on your network, the IGMP querier function
can be enabled for only one VLAN per switch. The IP address of the
querier may be different on each VLAN.
You can choose to assign the querier to the management VLAN or a
custom VLAN. The querier is assigned to the management VLAN by
default.
– If the querier is assigned to the management VLAN, the querier IP
address is the IP address defined on the Network Configuration tab, as
described in
Set the IP Address on page 15 .
– If you want to assign the querier to a custom VLAN, you must first set
up the custom VLAN on the VLAN Configuration tab, as described in
VLAN Configuration on page 57 . Assigning the querier to a custom
VLAN requires you to know which IP address you want to assign to the
querier.
• If you do not plan to use VLANs on your network, you can enable or
disable a single querier instance on the network. The querier function is
enabled by default. If more than one querier instance is detected on the
network, only the querier with the lowest IP address is active. All other
queriers are silent.
