Chapter 2 Catalyst 3560 Switch Cisco IOS Commands ipv6 mld snooping last-listener-query-interval 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. ipv6 mld snooping [vlan vlan-id] last-listener-query-interval integer_value no ipv6 mld snooping [vlan vlan-id] last-listener-query-interval Note This command is available only if the switch is running the advanced IP services image and you have configured a dual IPv4 and IPv6 Switch Database Management (SDM) template on the switch. Syntax Description vlan vlan-id integer_value (Optional) Configure last-listener query interval on the specified VLAN. The VLAN ID range is 1 to 1001 and 1006 to 4094. Set the time period (in thousands of a second) that a multicast router to wait after issuing a MASQ before deleting a port from the multicast group. The range is 100 to 32,768. The default is 1000 (1 second), 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 Command History Release 12.2(25)SED Modification This command was introduced. 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, 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. 78-16405-05 Catalyst 3560 Switch Command Reference 2-187
