MLD Snooping Querier Commands

ln 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.
Note: This note clarifies the prioritization of Multicast Group Membership Discovery (MGMD) Snooping
Configurations. Many of the IGMP/MLD Snooping commands are available both in the Interface and
VLAN modes. Operationally the system chooses or prefers the VLAN configured values over the Interface
configured values for most configurations when the interface participates in the VLAN.
5-503 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.
lf 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.
Use the no command to disable MLDSnooping Querier on the system. Use the optional parameter
address to reset the querier address.
set mld querier [vlan-id] {address ipv6_address | query-interval interval | timer [expiry interval ] }
no set mld querier [vlan-id] [address]
Parameters
vlan-id
address ipv6_address
query-interval 1-1800
(Optional) Display MLD Snooping querier VLAN ID information.
(Optional) Configure Querier IPv6 address.
Configure Querier Query interval.
