1、 The goal of the experiment

Put the device R1 As FTP The server , equipment R2 As client , Upload the files in the client to FTP The server , then FTP Download files from the server to the client , And separately in FTP Check whether the file is transferred successfully on the server and client

2、 Network topology

3、 Configuration steps

（1） Configure ports by topology IP Address

notes ： The port of the device IP Just as FTP Server or client IP Address

a、 configure port IP Address

R1：

<Huawei>system-view  // Enter the system view 
[Huawei]sysname R1  // Rename the device 
[R1]interface GigabitEthernet0/0/0
[R1-GigabitEthernet0/0/0]ip address 10.1.1.1 24  // configure port  IP  Address 
[R1-GigabitEthernet0/0/0]quit

R2：

<Huawei>system-view  // Enter the system view 
[Huawei]sysname R2  // Rename the device 
[R2]interface GigabitEthernet0/0/0
[R2-GigabitEthernet0/0/0]ip address 10.1.1.2 24  // configure port  IP  Address 
[R2-GigabitEthernet0/0/0]quit

b、 Test the connectivity between devices

use FTP The server （R1） Go to ping client （R2） Of IP Address （ port IP Address ）, It is found that it can be interconnected

[R1]ping 10.1.1.2
  PING 10.1.1.2: 56  data bytes, press CTRL_C to break
    Reply from 10.1.1.2: bytes=56 Sequence=1 ttl=255 time=70 ms
    Reply from 10.1.1.2: bytes=56 Sequence=2 ttl=255 time=30 ms
    Reply from 10.1.1.2: bytes=56 Sequence=3 ttl=255 time=20 ms
    Reply from 10.1.1.2: bytes=56 Sequence=4 ttl=255 time=10 ms
    Reply from 10.1.1.2: bytes=56 Sequence=5 ttl=255 time=20 ms

  --- 10.1.1.2 ping statistics ---
    5 packet(s) transmitted
    5 packet(s) received
    0.00% packet loss
    round-trip min/avg/max = 10/30/70 ms

Using the client （R2） Go to ping FTP The server （R1） Of IP Address （ port IP Address ）, It can also be interconnected

[R2]ping 10.1.1.1
  PING 10.1.1.1: 56  data bytes, press CTRL_C to break
    Reply from 10.1.1.1: bytes=56 Sequence=1 ttl=255 time=50 ms
    Reply from 10.1.1.1: bytes=56 Sequence=2 ttl=255 time=30 ms
    Reply from 10.1.1.1: bytes=56 Sequence=3 ttl=255 time=20 ms
    Reply from 10.1.1.1: bytes=56 Sequence=4 ttl=255 time=20 ms
    Reply from 10.1.1.1: bytes=56 Sequence=5 ttl=255 time=30 ms

  --- 10.1.1.1 ping statistics ---
    5 packet(s) transmitted
    5 packet(s) received
    0.00% packet loss
    round-trip min/avg/max = 20/30/50 ms

（2） stay FTP The server （R1） On the configuration FTP Function and FTP User information

AAA The server receives the data sent by the data device FTP User authentication information ; According to the preset FTP The user account authenticates and authorizes the authentication information , It can be managed centrally FTP user .

[R1]ftp server enable  // Turn on  FTP  function  
[R1]aaa
[R1-aaa]local-user ftptest password cipher ftptest123  // To configure  FTP  User information , user name ：ftptest  password ：ftptest123
[R1-aaa]local-user ftptest privilege level 15  // Configure the user's level 
[R1-aaa]local-user ftptest service-type ftp  // Configure the service type 
[R1-aaa]local-user ftptest ftp-directory flash:  // To configure  FTP  Catalog 
[R1-aaa]quit

（3） View the files in the device

notes ： To view files, you need to exit the system view , Use dir Command view file
R1：

[R1]quit  // Exit the system view 
<R1>dir
Directory of flash:/

5、 Summary

FTP Working in OSI The seventh layer of the model , TCP The fourth layer of the model , The application layer , Use TCP Transmission, not UDP, The client has to go through a “ Three handshakes ” The process of , Ensure that the connection between the client and the server is reliable , And it's connection oriented , Provide reliable guarantee for data transmission .
