ipv6 mld snooping last-listener-query-interval
Use the ipv6 mld snooping last-listener-query-interval global configuration command to configure IP
version 6 (IPv6) Multicast Listener Discovery (MLD) snooping last-listener query interval on the switch
or on a VLAN. This time interval is the maximum time that a multicast router waits after issuing a
Mulitcast Address Specific Query (MASQ) before deleting a port from the multicast group. Use the no
form of this command to reset the query time to the default settings.
This command is available only if the switch is running the metro IP access image and you have
Note
configured a dual IPv4 and IPv6 Switch Database Management (SDM) template on the switch.
Syntax Description
vlan vlan-id
integer_value
Command Default
The default global query interval (maximum response time) is 1000 (1 second).
The default VLAN query interval (maximum response time) is 0 (the global count is used).
Command Modes
Global configuration

Usage Guidelines
To configure the dual IPv4 and IPv6 template, enter the sdm prefer dual-ipv4-and-ipv6 global
configuration command and reload the switch.
In MLD snooping, when the IPv6 multicast router receives an MLD leave message, it sends out queries
to hosts belonging to the multicast group. If there are no responses from a port to a MASQ for a length
of time, the router deletes the port from the membership database of the multicast address. The last
listener query interval is the maximum time that the router waits before deleting a nonresponsive port
from the multicast group.
When a VLAN query interval is set, this overrides the global query interval. When the VLAN interval
is set at 0, the global value is used.
VLAN numbers 1002 through 1005 are reserved for Token Ring and FDDI VLANs and cannot be used
in MLD snooping.
