Hi Narendra,
When you use NCM to capture the device configurations they are stored in the SSdb as a model.
These models are then given an association to the parent device model.
You can see/get the configurations by selecting the host configuration tab on the device you need to see the configuration for.
Alternatively, you can also configure NCM to export each unique configuration to a directory on the SpectroSERVER when captured.
Hope this answers your question!
