Various applications, such as loading configurations, firmware versions, scripts, and verifying server identity with certificates, require the relevant files to be stored to the device. You can to upload these files to the device with LANconfig or WEBconfig.
As an alternative you can use the command line to load the corresponding files directly into the device using TFTP, HTTP(S) or SCP. This process mainly simplifies device administration in larger installations that rely on regular updates to the firmware and/or configurations. You can choose whether to transfer a file from a computer to the device by means of a client, or to use the command line to instruct the device itself to load the file from a server.
