ONFIGURING
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 multicast to the port
where the end device is located.
These pages enable you to configure and display information on MLD Snooping queriers on the network and, separately,
on VLANs.

Description
Select the administrative mode for MLD Snooping for the switch from the pulldown
menu. The default is Disable.
Specify the Snooping Querier Address to be used as source IPv6 address in periodic
MLD queries. This address is used when no address is configured on the VLAN on
which query is being sent.
Specify the MLD protocol version used in periodic MLD queries.
Specify the time interval in seconds between periodic queries sent by the snooping
querier. The Query Interval must be a value in the range of 1 and 1800. The default
value is 60.
Specify the time interval in seconds after which the last querier information is removed.
