The Inventory Management feature provides any external client that can use the REST API, such as the EMS, access to static inventory data for the DSC 8000 and the DSC SWe network elements. For a list of all the elements captured, see table Inventory List.
The DSC inventory data has the following characteristics:
- is independent of the operation status of the related equipment/units
- does not change frequently during the normal operation
- cannot be changed through the external client interface
- is independent of configuration management
- may include data showing static physical relations between equipment or units (for example, card A is in slot B)
- does not provide information for cards that are unavailable
To receive inventory data, the external client must be configured to use the DSC REST API and the REST API attribute enabled on the DSC. For more information about configuring the DSC REST API, refer to Authentication.
The data model for the Hardware Monitor (YIN file) is not automatically generated for the REST API resources. Instead, a custom resource with URL /api/inventory has been added to DSC REST API. For more information about data models, refer to Generation of REST API and DSC Data Models.
After the REST API is configured for both the external client and DSC, you can use the custom URL /api/inventory to return the inventory data. The URL must include Basic authorization, see the following HTTP GET example:
curl -k -u username:password -X GET \
https://{{service_ip}}:{{service_port}}/api/inventory
The inventory handler collects the information and performs a sanity check. If the sanity check fails, an error is returned. If the sanity check is successful, the inventory data is returned with the status code 200.
The following table lists the data attributes that the external client receives or can obtain from the DSC response:
For more detailed information about the hardware listed on the following table, refer to the appropriate DSC Installation Guide.
