Topology-related error messages occur most frequently during the following operations:
Batch import of network topology
Check the formatting of your batch import file. Refer to Batch Import File Sample. You must have DPAdmin privileges to import topology.
Creating regions
A region is created in the CNS security service when one is created in the dial plan. If the security service is unable to create the region, you receive errors.
Adding and modifying network elements
Check for acceptable values in the user interface and the online help. If the element has an invalid parameter, you receive errors.
Check the dial plan state of the element.
Persisting element configurations
VRC must be able to access the dial plan configuration.
When you encounter Topology error messages, use the console to set the debug of the Topology subsystem to on.
