A.Create a client service path by using the path method. After the creation, the optical layer OCh path is automatically generated to reduce the secondary teaching of the path creation.

B.The creation or search of a new path must be possible if its upper service layer path already exists.

C.Select the "Activate" checkbox. After the path is successfully created, it will be delivered to the NE layer. Otherwise, the path configuration text will only be saved on the network management side.

D.If the route to be automatically calculated is different from the planned path, you can set the "constrained node" or "must pass through the node" to perform routing constraints.
