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.

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.

Term

Definition

The VLAN in which the MAC address is learned.

01:23:45:67:89:AB.

The type of entry, which is either static (added by the user) or dynamic (added to the

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

The text description of this multicast table entry.

The list of interfaces that are designated for forwarding (Fwd:) and filtering (Flt:).
