LIFC_UNDER_IPMP is not available in Oracle Solaris 10, so applications supported on this release do not use LIFC_UNDER_IPMP. Thus, applications issuing a SIOCGLIFCONF request inside an Oracle Solaris 10 zone do not see underlying interfaces, but instead see only see the IPMP meta-interfaces. The ifconfig command used with the –a option shows the underlying interfaces because a solaris10 zone uses the Oracle Solaris 11 version of ifconfig, which passes the special LIFC_UNDER_IPMP. See if_tcp(7P) for details.
