MLD snooping configuration
Displaying MLD group information
To display MLD group information, enter the show ipv6 mld-snooping group command.
NOTE
In this example, an MLDv1 group is in EXCLUDE mode with a source of 0. The group excludes traffic
from the 0 (zero) source list, which actually means that all traffic sources are included.
To display detailed MLD group information, enter the show ipv6 mld-snooping group detail
command.
If tracking and fast leave are enabled, you can display the list of clients for a particular group by
entering the show ipv6 mld-snooping group tracking command.
Syntax: show ipv6 mld-snooping group [<group-address> [detail] [tracking]]
To receive a report for a specific multicast group, enter that group address for <group-address>.
Enter detail to display the source list of a specific VLAN.
Enter tracking for information on interfaces that are tracking-enabled.
The following table describes the information displayed by the show ipv6 mld-snooping group
command.
Field Description
