How to import devices from a CSV file for the latest Network Configuration Manager version? 

• Create a CSV file with the details of name/ip address of the device, display name and device type.
• Click on Setting > Discovery > Network Discovery to go to the Device Discovery page. 
• Select CSV File Import option.
• Browse and load the CSV file.
• Once it gets loaded, you will see field details, 'Configure fields from CSV file'.
• The file is parsed and the headers are shown on the right hand side.
• Once you see the headers for each row, you can map the required fields to the csv file. 
• After configuring the fields, select appropriate credentials from the list of available SNMP credentials, if the credentials are not pre-configured, you can always use the Add Credential button to add new credentials.
• Click 'Discover' and the discovery will start.

Note: DeviceName/IP header is a must for CSV file and other header fields are optional.
