10.4.3 Checking the Configuration
After options of MLD messages are configured, you can check MLD configurations and running
information on the interface to ensure normal running of MLD.
Procedure

[ verbose ] command to check the MLD configuration and running information on an
interface.

10.5 Configuring MLD Query Control
An MLD querier periodically sends MLD Query messages on a shared network segment to
refresh information about IGMP group members. MLD parameters configured on all the
interfaces of the multicast devices on the same network segment with the user host should be
consistent; otherwise, a fault occurs on the network.
10.5.1 Establishing the Configuration Task
Before configuring MLD query control, familiarize yourself with the applicable environment,
pre-configuration tasks, and required data. This can help you complete the configuration task
quickly and accurately.
Applicable Environment
CAUTION
A great many of MLD interfaces exist in the network and these MLD interfaces are mutually
restricted. Ensure that all MLD parameters of all MLD switch interfaces on the same network
segment are identical. Otherwise, the network may be faulty.
