Difference between logical fibers on a WDM/OTN device and those on an MSTP/SDH device
Each logical fiber on an SDH device represents a pair of physical fibers and each logical fiber on a WDM device represents one physical fiber.

Rollback of OSN 8800 T32
You can use the :sftm-rtrv-state:swdl command to query the current status, which can be is cpy file end/normal. You can use the :sftm-abt-cmd command to roll back to the double-normal state to create tasks again, or directly create tasks to perform Dispense, Activate, and Commit operations.

Precautions for using commands to delete board-level cross-connections and then create NE-level cross-connections on OSN 6800 devices
Question: After an engineer changes board-level optical cross-connections of a pass-through wavelength on an OSN 6800 NE (version: 5.51.04.13) to NE-level optical cross-connections using a command (direct change on the T2000 will cause a transient service interruption), services on the wavelength are interrupted. In addition, when the engineer attempts to delete the NE-level optical cross-connections on the T2000 (version: V200R007C01), the T2000 displays a message indicating that the NE-side optical cross-connections do not exist. Why? Analysis: 1. An error occurs during service creation using the command. 2. The system control board or dynamic optical-layer grooming board ROAM is faulty. Answer: 1. NE-level or board-level optical cross-connections can be created for other wavelengths on the T2000. This means that the failure of the system control board or ROAM board can be excluded. 2. In the output of the :cfg-get-e2eoxc:0,0; command for querying NE-level optical cross-connections, the ROAM optical cross-connection status of the wavelength is 0000 rather than active, adding, or deleting. 3. NE-level optical cross-connections can be created for the wavelength using a command, and the NE-level optical cross-connections on the wavelength can also be deleted from the T2000. 4. The sequence of the operations performed by the engineer is as follows: Delete the board-level optical cross-connections on the wavelength. --> Create NE-level optical cross-connections for the wavelength. --> Query the NE- and board-level optical cross-connections on the wavelength. (All optical cross-connections on the wavelength can be queried). --> Delete the board-level optical cross-connections on the wavelength and check optical cross-connection status. 5. After board-level optical cross-connections are deleted using commands, the optical cross-connection status is always deleting if it is not verified, but services are not interrupted. After the engineer creates board-level optical cross-connections, the status of board-level optical cross-connections changes to active. In this case, after the verification command is issued, the wavelength cannot be displayed if the engineer queries board-level optical cross-connections, but can be displayed if the engineer queries NE-level optical cross-connections. 6. When the engineer queries the board- and NE-level optical cross-connections, the wavelength can be displayed. As a result, the engineer mistakenly determines that the optical cross-connections are not deleted and therefore deletes the optical cross-connections again. Consequently, the optical cross-connections are incomplete on the NE side. Suggestion and conclusion: If board-level optical cross-connections are deleted using commands, the board-level optical cross-connections cannot be displayed during the optical cross-connection query upon creation command issuing.

Commands used to query reset records of an NG WDM device
Run the :errlog command to query the reset records of an NE. Run the :mon-get-errlog:bid command to query the reset records of a board.
