4.8.2 IGMP
Query
This page allows user to configure the
IGMP Query
feature. Since
JetNet 4706/4706f
can
only be configured by the member ports of the management VLAN, so that the IGMP
Query can only be enabled on the management VLAN. If you want to run IGMP Snooping
feature in several VLANs, you should notice that whether each VLAN have their own IGMP
Querier first.
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.
In the IGMP Query selection, you can select V1, V2 or Disable.
V1
means IGMP V1
General Query. The query will be forwarded to all multicast groups in the VLAN.
V2
means
IGMP V2 Specific Query. The query will be forwarded to specific multicast groups.
Disable
allows you to disable the IGMP Query.
Once you finish configuring the settings, click the
Apply button
to apply your
configuration.
