      should be down(2).  If ipv6IfAdminStatus is changed

      to up(1) then ipv6IfOperStatus should change to up(1)

      if the interface is ready to transmit and receive

      network traffic; it should remain in the down(2) or

      noIfIdentifier(3) state if and only if there is a

      fault that prevents it from going to the up(1) state;
