ONFIGURATION

By default a switch can operate as a TFTP client. In this case you can connect the 
switch to the TFTP server to perform TFTP-related operations (such as 
creating/removing a directory) by executing commands on the switch. Table 337 
lists the operations that can be performed on a TFTP client.

A switch operates as a TFTP client and a PC as the TFTP server. The application 
named switch.bin is stored on the PC. Download it (switch.bin) to the switch 
through TFTP, and use the boot boot-loader command to specify switch.bin as 
the application for next startup. Reboot the switch to upload the configuration file 
named config.cfg to the work directory on the PC to back up the configuration 
file.

■

The TFTP working directory is configured on the TFTP server.

■

Configure the IP addresses of a VLAN interface on the switch and the PC as 
1.1.1.1 and 1.1.1.2 respectively. The port through which the switch connects 
with the PC belongs to the VLAN.
