Step5 Upgrade an application file.
Using FTP, you can download an application file from the server to the device, and overwrite the original
main application file to upgrade the application. The upgraded application file takes effect when the
device reboots.
# Download file main.bin from the FTP server to the device and save it as main.bin.
[ftp]get main.bin main.bin
flash:/main.bin has been existing. Overwrite it? [Y/N]:y
227 Entering passive mode (192,168,80,200,5,33)
125 Using existing data connection
226 Closing data connection; File transfer successful.
FTP: 11611272 byte(s) received in 472.515 second(s), 23.00K byte(s)/sec
When you download an application file, if a file having the same name with the downloaded file
exists on the device, the system prompts whether to overwrite the file on the device. You need to
choose Y or N for confirmation.
For details about the get command, see the accompanying documentation.
You can upgrade a configuration file using the same method as upgrading an application file. A
configuration file can be modified by a text editor. You can modify a configuration file and then
download the modified configuration file to the device, and the modification takes effect after the
device reboots.
Step6 Back up an application file.
Using FTP, you can backup an application file by uploading it to the server.
# Upload file main.bin from the device to the server, and save it as main.bin.
[ftp]put main.bin main.bin
227 Entering passive mode (192,168,80,200,5,34)
125 Using existing data connection
226 Closing data connection; File transfer successful.
FTP: 11611272 byte(s) sent in 172.505 second(s), 63.00Kbyte(s)/sec
[ftp]quit
221 Service closing control connection
When you back up an application file, if a file having the same name with the file to be backed up
exists on the server, the system overwrites the file on the server directly.
For details about the put command, see the accompanying documentation.
You can backup a configuration file using the same method as backing up an application file.
