Whether the logical fibers between the client-side ports of OLP and OTU boards need to be created on the NMS

When port protection or 1+1 protection is configured in single-site mode, it is not mandatory to configure logical fibers. This is because boards and ports are specified in single-site configuration and there is no need to search for boards or ports based on logical fibers.
Correct logical fibers created on the NMS provide references for configuration and check. Therefore, you are advised to correctly create logical fibers on the NMS.
