ArcSight Professional Services can help you populate the Network Model from an existing configuration database.
Many enterprise networks have third-party systems that already model the properties of the assets on your network. With the help of ArcSight Professional Services, you can export these network models, translate the format into the schema using an ArcSight resource-generating utility, and import it to the Manager as a resource archive with the help of ArcSight Professional Services.
The tools ArcSight Professional Services use can generate any type of resource, so using this method, you can have a fully populated network model without having to do any individual configuration.
