This lets a management station set the desired administrative state of a Fibre Channel QxPort on the QLogic switch - bringing it online, taking it offline, or placing it into a testing mode where no operational frames pass. Administrators use it to manually control port availability, for instance taking a port offline before performing maintenance on the attached cable or device. Since all QxPorts start offline when the Fabric Element initializes, an admin (or an automatic configuration process) must explicitly set this object to online before that port can actually pass Fibre Channel traffic.
