Chapter 2<strong>Catalyst</strong> <strong>3750</strong>-E <strong>and</strong> <strong>3560</strong>-E <strong>Switch</strong> <strong>Cisco</strong> <strong>IOS</strong> Comm<strong>and</strong>sipv6 mld snooping vlanThe configuration <strong>and</strong> the static ports <strong>and</strong> groups are saved in NVRAM.When the IPv6 multicast router is a <strong>Catalyst</strong> 6500 switch <strong>and</strong> you are using extended VLANs (in therange 1006 to 4094), IPv6 MLD snooping must be enabled on the extended VLAN on the <strong>Catalyst</strong> 6500switch in order for the <strong>Catalyst</strong> <strong>3750</strong>-E or <strong>Catalyst</strong> <strong>3560</strong>-E switch to receive queries on the VLAN. Fornormal-range VLANs (1 to 1005), it is not necessary to enable IPv6 MLD snooping on the VLAN on the<strong>Catalyst</strong> 6500 switch.VLAN numbers 1002 through 1005 are reserved for Token Ring <strong>and</strong> FDDI VLANs <strong>and</strong> cannot be usedin MLD snooping.Examples This example shows how to enable MLD Immediate-Leave processing on VLAN 1:<strong>Switch</strong>(config)# ipv6 mld snooping vlan 1 immediate-leaveThis example shows how to disable MLD Immediate-Leave processing on VLAN 1:<strong>Switch</strong>(config)# no ipv6 mld snooping vlan 1 immediate-leaveThis example shows how to configure a port as a multicast router port:<strong>Switch</strong>(config)# ipv6 mld snooping vlan 1 mrouter interface gigabitethernet1/0/2This example shows how to configure a static multicast group:<strong>Switch</strong>(config)# ipv6 mld snooping vlan 2 static FF12::34 interface gigabitethernet1/0/2You can verify your settings by entering the show ipv6 mld snooping vlan vlan-id user EXECcomm<strong>and</strong>.Related Comm<strong>and</strong>s Comm<strong>and</strong> Descriptionipv6 mld snoopingEnables IPv6 MLD snooping.ipv6 mld snooping vlanConfigures IPv6 MLD snooping on the VLAN.sdm prefer dual-ipv4-<strong>and</strong>-ipv6Configures an SDM template to support IPv6functions.show ipv6 mld snoopingDisplays IPv6 MLD snooping configuration.OL-9776-08<strong>Catalyst</strong> <strong>3750</strong>-E <strong>and</strong> <strong>3560</strong>-E <strong>Switch</strong> Comm<strong>and</strong> Reference2-305
