■

If the free Flash memory of the switch is not enough for downloading the 
application file from the FTP server, remove those unused applications from the 
Flash memory before downloading the file.

■

 It is not recommended to directly remove applications in use. If removing some 
applications in use is a must to get enough space, you can use the BootROM 
menu to remove them.

Compared with FTP, Trivial File Transfer Protocol (TFTP) features simple interactive 
interface with no authentication control and is therefore applicable to the 
networks where client-server interactions are relatively simple.

Figure 104   Network diagram for configuring a switch as TFTP client

 

A switch operates as a TFTP client and a remote PC as a TFTP server.

■

Configure the IP address of VLAN-interface 1 on the switch as 1.1.1.1/16, and 
that of the PC as 2.2.2.2/16. The switch and PC can reach each other.

■

An application named switch.bin is stored on the PC. The switch downloads 
switch.bin through TFTP to upgrade the application.

■

The switch uploads the configuration file config.cfg to the PC for backup.

■

Configure the TFTP working folder on the TFTP server. For detailed 
configurations, refer to the usage instructions about the TFTP server software.
