Configuring an FTP operation
An FTP operation measures the time the NQA client uses to transfer a file to or download a file from an
FTP server.
Follow these guidelines when you configure an FTP operation:
• Before you perform an FTP operation, obtain the username and password for logging in to the FTP
server.
• When you execute the put command, the NQA client creates a file named file-name of fixed size
on the FTP server. When you execute the get command, the client does not save the file obtained
from the FTP server.
• If you get a file that does not exist on the FTP server, the FTP operation fails.
• Only use the get command to download a small file. A big file might result in transfer failure
because of timeout, or might affect other services for occupying much network bandwidth.
