Asset Ranges CSV File Format
Asset ranges represent sets of network nodes addressable as a contiguous block of IP addresses. Asset ranges are useful when you have a number of network nodes that would be impractical to track individually, or that may come and go from the network, such as laptops. An asset range can define a group of assets that are not addressed individually. Asset ranges should be a subset of the IP address ranges defined for zones.
Caution: Each asset range should specify a unique range of IP addresses. The IP addresses specified by asset ranges should not overlap. If you import an asset range that overlaps with an asset range already specified on the ArcSight Manager and the new asset range has a different name than the existing asset range, the following occurs:
-
The new asset range is created.
-
The existing asset range is invalid and displays with the broken asset range icon in the Console.
You can define a set of asset ranges in ESM by batch loading asset range definitions from an asset range CSV file. Asset range CSV files contain the columns listed in the table, below. When an assets CSV file is selected for import, by default only the first fifteen rows of data are displayed in Select Column Headers for the Asset Ranges Data panel. However, when the data is imported into the ArcSight Manager, all the rows are imported. For more information, see Increasing the Number of Displayed Rows.
For the wizard to determine how to process the imported data, the type of each column must be specified. For more information, see Specifying CSV Column Types.
When the Next button is clicked in the Summary of Data to Import panel, the asset range data is imported into the ArcSight Manager. The new asset ranges are created in the /All Assets/Site Assets group. For example, if an asset range called DMZCorpHR was specified in the imported asset range CSV file, a new asset range is created at the following URI: /All Assets/Site Assets/DMZCorpHR.
