FTP operating environment and notes
A FTP probe acquires a measurement file from the measurement-target FTP server, or transfers a prepared measurement file to the measurement-target server and measures the time required for file transfer. The measurement file must already be stored in the following folder:
The following describes and provides notes on a FTP operating environment.
Handling of the transferred file
Handling of the transferred file depends on the transfer direction, as described below:
Data type during transfer
The FTP probe supports only the ASCII data type during transfer.
RFC compliance
For the functions that are not compliance with RFCs and the restrictions, see the above notes.
