Edit: Doh! I completely missed the part where Smartconsole was used. I was thinking API specifically.
Can you provide an example of the Application/Site that you were wanting to configure? I was able to used a single columned CSV file with multiple domains, hosts, etc. to successfully populate the object and then publish to the management.
Which commands were used when attempting to use the CSV file?
Can you post an example of the CSV file?
Have you seen the example used at the end of the R80.10 API guide?
