Principle overview
FTP (File Transfer Protocol) is one of the earliest protocols used on the TCP / IP network and the Internet, and belongs to the application layer protocol in the TCP / IP protocol cluster.
It is an Internet standard for file transfer, and mainly provides users with file transfers from local and remote hosts, especially when performing version upgrades, log downloads, and configuration saving services.
FTP adopts C / S (Client / Server) structure. FTP can provide original client access and operation functions. Users can log in to the server through the host to upload and download files.
FTP experiment topology
R1 placement
After configuring the IP to test whether the client and the server are reachable, create a folder FTP-Huawei on the local computer as the FTP server folder, create a subfolder Config under the folder, and create a test file test.txt, and start after completion ftp server, use the ftp command to connect to the ftp server on R1. The user name is required by default when logging in. Because the server does not have it, each time you enter it on R1, it is equal to creating the user name and password. This time the user name is 10.0.2.1, and the password is huawei

Router is configured as FTP Server
The above router as the client has been successfully downloaded and uploaded, set the ftp login password ftp / huawei, set the folder directory to "flash:", priority 3
<R1>system-view
Enter system view, return user view with Ctrl+Z.
[R1]aaa
[R1-aaa]local-user ftp password cipher huawei
[R1-aaa]local-user ftp ftp-directory flash:
[R1-aaa]local-user ftp service-type ftp
[R1-aaa]local-user ftp privilege level 3
After the configuration is complete, create usertext.txt locally, and set the client server address 10.0.1.254, user name ftp, password huawei, click login, after login is complete, you can select the usertext file, and click the right arrow to send to the ftp server, File uploaded successfully
View the files in the directory on R1
