The switch application switch.app is stored on the PC. Using FTP, the PC can 
upload the switch.app from the remote FTP server and download the vrpcfg.cfg 
from the FTP server for backup purpose.

1 Configure the switch

# Log into the switch through the console port locally or Telnet remotely, and start 
FTP function and set username, password and file directory.

[SW8800] ftp server enable

 

[SW8800] local-user switch

 

[3Com-luser-switch] service-type ftp ftp-directory flash:

2 Run FTP client on the PC and establish FTP connection. Upload the switch.app to 

the switch under the Flash directory and download the vrpcfg.cfg from the switch.

the application at the next login and reboot the switch.

<SW8800> boot boot-loader switch.app

 

<SW8800> reboot 

Trivial File Transfer Protocol (TFTP) is a simple file transmission protocol. It is initially 
designed for the booting of free-disk systems (work stations or X terminals in

complicated interactive access interface or authentication control, and therefore it 
can be used when there is no complicated interaction between the clients and 
server. TFTP is implemented on the basis of UDP.

TFTP transmission is originated from the client end. To download a file, the client
