33:33:45:67:89:AB. In an IVL system, the MAC address is displayed as a MAC address
and a VLAN ID combination of 8 bytes.

table as a result of a learning process or protocol.)

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.
