Example for Using FTP to Access Other Devices

You can log in to the FTP server from the FTP client to download system software and configuration files from the FTP server to the client.

Networking Requirements

To transfer files with a remote FTP server or manage directories of the server, configure a device as an FTP client and use FTP to access the FTP server.

As shown in Figure 1, the FTP client and server are routable. To download system software and configuration files from the FTP server to the FTP client, log in to the FTP server from the FTP client.

Figure 1 Using FTP to access another device

In this example, interface 1 represents GE 0/1/1.

Configuration Roadmap

The configuration roadmap is as follows:

Configure the user name and password for an FTP user to log in to the FTP server and the directory that the user will access.
Enable the FTP server function.
Run login commands to log in to the FTP server.
Configure the file transfer mode and working directory to allow the client to download files from the server.

Data Preparation

To complete the configuration, you need the following data:

User name and password used by the FTP client for login
IP address of the FTP server: 1.1.1.1
Name of the file to be downloaded and directory of the file

Procedure

Configure an FTP user on the FTP server.
```
<HUAWEI> system-view
[~HUAWEI] aaa
[*HUAWEI-aaa] local-user huawei password
Please configure the password (8-128)
Enter Password:
Confirm Password:
```
The password must meet the following requirements:
- The password is entered in man-machine interaction mode. The system does not display the entered password.
- A password is a string of 8 to 16 case-sensitive characters and must contain at least two types of the following characters: uppercase letters, lowercase letters, digits, and special characters.
- Special characters exclude question marks (?) and spaces. However, spaces are allowed in the password if the password is enclosed in quotation marks.
  - Double quotation marks cannot contain double quotation marks if spaces are used in a password.
  - Double quotation marks can contain double quotation marks if no space is used in a password.
  For example, the password "Aa123"45"" is valid, but the password "Aa 123"45"" is invalid.
The configured password is displayed in ciphertext in the configuration file.
```
[*HUAWEI-aaa] local-user huawei service-type ftp
[*HUAWEI-aaa] local-user huawei ftp-directory cfcard:/
[*HUAWEI-aaa] local-user huawei level 3
[*HUAWEI-aaa] commit
[*HUAWEI-aaa] quit
```

Enable the FTP server function.

[~HUAWEI-LoopBack0] ip address 10.1.1.1 255.255.255.255
[*HUAWEI-LoopBack0] quit
[*HUAWEI] ftp server enable
[*HUAWEI] ftp server-source -i loopback 0
[*HUAWEI] commit

The current local directory is new_dir:. 
[ftp] commit

Download the latest system software from the FTP server to the FTP client.
