Expected state of the interface. In testing state the
interface does not forward any operational packets. When
a managed system is initialized, all interfaces start with
hh3cDot11APIfAdminStatus in the down state. As a result
of either explicit management action or per configuration
information retained by the managed system,
hh3cDot11APIfAdminStatus is then changed to either the up
or testing state or remains in the down state.
