IsIN Number of source addresses that were included in the traffic.
IsEX Number of source addresses that were excluded in the traffic.
ToIN Number of times the interface mode changed from EXCLUDE to INCLUDE.
ToEX Number of times the interface mode changed from INCLUDE to EXCLUDE.

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
Syntax: show ipv6 multicast vlan [vlan-id]
If you do not specify the vlan-id variable, information for all VLANs is displayed.
The following table describes information displayed by the show ipv6 multicast vlan command.
Field Description
version The MLD version number.
query-t How often a querier sends a general query on the interface.
group-aging-t Number of seconds membership groups can be members of this group before aging out.
rtr-port The router ports which are the ports receiving queries. The display router ports:
1/36(120) 2001:DB8: :2e0:52ff:fe00:9900 means port 1/36 has a querier with
2001:DB8::2e0:52ff:fe00:9900 as the link-local address, and the remaining life is 120 seconds.
max-resp-t The maximum number of seconds a client can wait before it replies to the query.
non-QR Indicates that the port is a non-querier.
