Maintaining the AC Through the TFTP Server 

In the TFTP service, H3C WX5002 AC serve as TFTP clients, while the file server serves as the TFTP 
server. You can enter commands on the PC to upload or download configuration files and application 
programs of the AC to or from the file server. 

Setting up a configuration environment 

First, set up a hardware environment (for the procedure, refer to section “Upgrading an Application 
Program” on page 5-12), and point the server path to the directory where the file is stored. 

Figure 5-8 

Network diagram for maintenance through command lines 

 

 

 

Configure the IP addresses of the two sides on the same network. For example, the IP address of the 
TFTP server is set to 192.168.0.1, and that of the AC is set to 192.168.0.2. Use the 

ping

 command on 

the TFTP server or AC to check whether the connection is successful. 

Backing up and restoring application programs and configuration files 

After setting up the environment, perform the following operations on the PC: 

View the files included in the current file system with the 

dir

 command. 

<H3C>dir

Use the following command to upload the startup.cfg file from the AC to the TFTP server and save it as 
startup.bak. 

<H3C>tftp 192.168.0.1 put startup.cfg startup.bak
