Symptom
The OptiX OSN 6800 V100R003 system is used in a new site. In the ROADM network comprising the WSD9 and RMU9, the L4G is used. After fiber connections are created, OTS and OMS routes are found. Create GE services by using the end-to-end trail function on the T2000V200R006C01. Firstly, create OCh service trails end to end by using the WDM trails. The system should automatically complete the optical cross-connection configuration. It, however, cannot continue to create end-to-end GE services.
Cause analysis
In the
ROADM network comprising the WSD9 and RMU9, after we created OCh trails, only
the OCh trails on optical layer are created. The electrical-layer service
trails of the ODU 5G and OTU 5G, however, are not created. Currently, the ODU
5G and OTU 5G can be discovered only through searching. Client GE services must
be created on OCh optical-layer trails and the electrical-layer service trails
of the ODU 5G and OTU 5G. For the relation between trails on each layer, refer
to the attachment.
Procedure
After OCh trails are created, use the WDM trail searching function. The electrical-layer service trails of the ODU 5G and OTU 5G are discovered after the searching. Then, use the WDM trail function to create client GE services. In this case, the system automatically completes the electrical cross-connection configuration.
Reference Information
The end-to-end grooming is a very important section in WDM service management. The T2000 supports the creation of end-to-end services on the network layer. After the user specifies the source and sink of a service, the T2000 is able to generate a client trail after it searches out the service trail. The creation of WDM trails effectively simplifies the service configuration process and guarantees the correctness of the operation. In addition, the service grooming and allocation in deployment or capacity expansion are more flexible. When you create end-to-end services on the T2000, search the trails after you create OCh trails. Then, configure client services.
