Version 9.14(1.0) 9.11(3.0) Description Updated the output to show both MLD versions 1 and 2. Introduced on the S3048-ON, S4048-ON, S4048T-ON, S6000-ON, S6010-ON, S6100-ON, Z9100-ON, S3100, and C9010. Example DELL EMC# show ipv6 mld vrf red interface vlan 100 Vlan 100 Inbound MLD access group is not set Internet address is 61::9/64 MLD is up on the interface MLD query interval is 60 seconds MLD querier timeout is 0 seconds MLD max query response time is 10 seconds MLD last member query response interval is 1000 ms MLD immediate-leave is disabled MLD activity: 40 joins MLD querying router is fe80::211:33ff:fe44:7788 MLD version is 1 MLD Snooping MLD snooping allows the switch to examine the MLD packets and forwards the decision based on their content. You can configure MLD snooping in subnets that receive MLD queries from either MLD or the MLD snooping querier. MLD snooping limits the IPv6 multicast traffic at Layer 2 by configuring Layer 2 LAN ports and dynamically forwards the IPv6 multicast traffic to the ports that want to receive it. Hosts join IPv6 multicast groups either by sending an unsolicited MLD report or by sending an MLD report in response to a general query from an IPv6 multicast router (the switch forwards general queries from IPv6 multicast routers to all the ports in a VLAN). The switch snoops these reports and in response to a snooped MLD report, the switch creates an entry in its forwarding table for the VLAN on which the report was received. When the other hosts that are interested in this multicast traffic send MLD reports, the switch snoops their report and adds them to the existing forwarding table entry. The switch creates only one entry per VLAN in the forwarding table for each multicast group, for which it snoops an MLD report. clear ipv6 mld snooping groups Clear entries from the group cache table. Syntax Parameters clear ipv6 mld snooping groups [interface | group-address] interface Enter the following keywords and slot/port or number information: • For a 1-Gigabit Ethernet interface, enter the keyword GigabitEthernet followed by the slot/port information. • For a Port Channel interface, enter the keywords port-channel then a number. • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port information. • For a VLAN, enter the keyword vlan followed by a number from 1 to 4094. 1102 Multicast Listener Discovery Protocol
