l Run the display mld explicit-tracking [ interface interface-type interface-number [ host-
address ipv6-host-address | group ipv6-group-address source ipv6-source-address ] ]
command in any view to check information about the MLD hosts on an interface.
l Run the display mld group [ ipv6-group-address | interface interface-type interface-
number ]
*
[ static ] [ verbose ] command in any view to check information about groups
on each interface.
l Run the display mld group [ ipv6-group-address | interface interface-type interface-
number ]
*
ssm-mapping [ verbose ] command in any view to check information about a
group configured with SSM mapping.
l Run the display mld interface [ interface-type interface-number ] [ verbose ] command
in any view to check the MLD configuration and running information on an interface.
l Run the display mld routing-table [ ipv6-source-address [ ipv6-source-mask-length ] |
ipv6-group-address [ ipv6-group-mask-length ] ]
*
[ static ] [ outgoing-interface-
number [ number ] ] command in any view to check the MLD routing table.
l Run the display mld ssm-mapping interface [ interface-type interface-number [ group
ipv6-group-address ] ] command in any view to check information about an interface
