Precautions for OSN 6800 to use command lines to delete board optical cross-connections or create single-site optical cross-connections

(1) The single-site or board optical cross-connections of other wavelengths are successfully created on the NMS. Therefore, the system control board fault or ROAM fault of the optical-layer scheduling board is ruled out. (2) When the cfg-get-e2eoxc:0,0 command is used to query the single-site optical cross-connections, the optical cross-connection of the wavelength on the ROAM is 0000, which is abnormal. The state should be one of active, adding, and deleting. (3) When a command line is used to create the single-site optical cross-connection of the wavelength, the optical cross-connection is successfully created. In addition, the single-site optical cross-connection of the wavelength can also be successfully deleted from the NMS. (4) Check the operation records of the onsite engineer and find that the procedure is as follows: Check the board optical cross-connection of the wavelength à Create the single-site optical cross-connection of the wavelength à Query the board and single-site optical cross-connections of the wavelength. The wavelength is present on both the board optical cross-connection and single-site optical cross-connection. Then, you can delete the board optical cross-connection and verify it.
(5) If the board optical cross-connection is deleted using a command line but no verification is performed, services will not be interrupted when the board optical cross-connection is in the deleting state. If a single-site optical cross-connection is created at that time, the board optical cross-connection will become the active state. After the verification command is successfully delivered, the wavelength cannot be found in the board optical cross-connection and it can be queried only in the single-site optical cross-connection. (6) Because the onsite engineer found the wavelength both in the board optical cross-connection and single-site optical cross-connection, the engineer falsely determined that the optical cross-connection was not successfully deleted and then deleted it again. As a result, optical cross-connections on the NE software side are incomplete.
