ipv6 mld snooping last-listener-query-count
Use the ipv6 mld snooping last-listener-query-count global configuration command on the switch

Address Specific Queries (MASQs) or that will be sent before aging out a client. Use the no form of this
command to reset the query count to the default settings.
ipv6 mld snooping [vlan vlan-id] last-listener-query-count integer_value
no ipv6 mld snooping [vlan vlan-id] last-listener-query-count
Note This command is available only if you have configured a dual IPv4 and IPv6 Switch Database
Management (SDM) template on the switch.
Syntax Description
Command Default The default global count is 2.
The default VLAN count is 0 (the global count is used).
Command Modes Global configuration
Command History
Usage Guidelines To configure the dual IPv4 and IPv6 template, enter the sdm prefer dual-ipv4-and-ipv6 {default | vlan)
global configuration command and reload the switch.
In MLD snooping, the IPv6 multicast router periodically sends out queries to hosts belonging to the
multicast group. If a host wants to leave a multicast group, it can silently leave or it can respond to the
query with a Multicast Listener Done message (equivalent to an IGMP Leave message). When
Immediate Leave is not configured (which it should not be if multiple clients for a group exist on the
same port), the configured last-listener query count determines the number of MASQs that are sent
before an MLD client is aged out.
When the last-listener query count is set for a VLAN, this count overrides the value configured
globally.When the VLAN count is not configured (set to the default of 0), the global count is used.
VLAN numbers 1002 through 1005 are reserved for Token Ring and FDDI VLANs and cannot be used
in MLD snooping.
vlan vlan-id (Optional) Configure last-listener query count on the specified VLAN. The
VLAN ID range is 1 to 1001 and 1006 to 4094.
integer_value The range is 1 to 7.
