Chapter 2 Cisco IOS Commands for the Catalyst 4500 Series Switches

ipv6 mld snooping last-listener-query-count

To configure IP version 6 (IPv6) Multicast Listener Discovery Mulitcast Address Specific Queries
(MASQs) that will be sent before aging out a client, use the ipv6 mld snooping
last-listener-query-count command. To reset the query count to the default settings, use the no form of
this command.

integer_value
Command Default

Command Modes Global configuration mode
Command History Release

Usage Guidelines
In MLD snooping, the IPv6 multicast switch 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 (it should not be configured 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.
