ACS server pull or get log file from CPE

Is there any test procedure from UI page or curl command to trigger ACS server to query the vendor log file from CPE? I think it should have a curl command to do this. I tried but didn’t succeed. Is there anyone know how to test this scenario?

curl -i ‘’ -X POST --data ‘{ “name” : “upload”, “objectName” : “4 Vendor Log File” }’

Thanks for all your help
