The FC-SP mode of this interface. If off(1), port would never initiate FC-SP authentication exchange and send reject to any FC-SP authentication message started from other end. If autoPassive(2), a port would not initiate any FC-SP authentication exchange; but would always take part in FC-SP authentication exchange initiated on this interface by other devices. If autoActive(3), a port would always try to initiate FC-SP authentication exchange after ESC. If otherside does not support FC-SP authentication, port will still be brought up. If the authentication fails, the port will not be brought up. If on(4), port would always try to initiate FC-SP authentication exchange and authentication is done before the port becomes up. If otherside does not support FC-SP authentication or if authentication fails, port will not be brought up.
