MLD Snooping Querier Commands

In an IPv6 environment, MLD Snooping requires that one central switch or router periodically
query all end-devices on the network to announce their multicast memberships. This central
device is the MLD Querier. The MLD query responses, known as MLD reports, keep the
switch updated with the current multicast group membership on a port-by-port basis. If the
switch does not receive updated membership information in a timely fashion, it will stop
forwarding multicasts to the port where the end device is located.
This section describes the commands you use to configure and display information on MLD
Snooping queries on the network and, separately, on VLANs.

set mld querier

Use this command to enable MLD Snooping Querier on the system (Global Config Mode) or
on a VLAN. Using this command, you can specify the IP address that the snooping querier
switch should use as a source address while generating periodic queries.
If a VLAN has MLD Snooping Querier enabled and MLD Snooping is operationally disabled
on it, MLD Snooping Querier functionality is disabled on that VLAN. MLD Snooping
functionality is re-enabled if MLD Snooping is operational on the VLAN.
The MLD Snooping Querier sends periodic general queries on the VLAN to solicit
membership reports.
