When End-to-End GE Services Cannot Be Created on the OptiX OSN 6800?

Issue Description

In the case of a newly deployed OptiX OSN 6800 V100R003, the WSD9 and the RMU9 form an ROADM network, in which the L4G boards are used. After optical fiber connections are established, OTS and OMS trails are found. Enable the end-to-end trail function to create GE services on the T2000 V200R006C01. After the OCh service layer trail is created by using the WDM end-to-end trail function to create, the system automatically completes the optical cross-connection configuration, but it fails to create the end-to-end GE services.

Alarm Information

Null

Handling Process

After the OCh trails are created, use the WDM trail search function to search the electrical layer service trails of the ODU5G and the OTU5G. Then, use the WDM trail function to create client GE services. The system automatically completes the electrical cross-connection configuration.

Root Cause

After creating the OCh trails in the ROADM network formed by the WSD9 and the RMU9, check the trails. Only optical layer OCh trails are created. The electrical layer service trails of the ODU5G and the OTU5G, however, are not created. The ODU5G and the OTU5G can be discovered only through the search function. Client GE services must be created above the service trails of the OCh optical layer and the OTU5G/ODU5G electrical layer. The following figure shows the relations between trails of different layers.

Suggestions

End-to-end grooming is an important function in WDM service management. The T2000 supports creating end-to-end services at the network layer. After you specify the service source and the service sink, the T2000 can search the service trails and then generate corresponding client trails. The WDM trail creation process effectively simplifies the service configuration and improves operation correctness. It can also perform flexible service grooming and deployment during deployment commissioning or capacity expansion. When you configure the end-to-end service on the T2000, remember to search the created OCh trails before configuring client services.
