Displaying MLD snooping information by VLAN

You can display MLD snooping information for all VLANs or for a specific VLAN. For example, to display MLD snooping information for VLAN 70, enter the show ipv6 multicast vlan command.

device#show ipv6 multicast vlan 70

version=1, query-t=60, group-aging-t=140, max-resp-t=3, other-qr-present-t=123 VL70: cfg V2, vlan cfg passive, 2 grp, 0 (SG) cache, rtr ports,

router ports: 1/36(120) 2001:DB8::2e0:52ff:fe00:9900, 1/26 has 2 grp, non-QR (passive), cfg V1

1/26 has 2 grp, non-QR (passive), cfg V1 group: ff10:1234::5679, life = 100 group: ff10:1234::5678, life = 100

1/35 has 0 grp, non-QR (QR=2001:DB8::2e0:52ff:fe00:9900, age=20), dft V2 trunk
