[SW8800] ftp server enable 

[SW8800] local-user switch 

[SW8800-luser-switch] service-type ftp ftp-directory flash:  

[SW8800-luser-switch] password simple hello 

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. 

FTP client is not shipped with the switch, so you need to buy it separately.  

 

If the Flash Memory of the switch is not enough, you need to first delete the existing 

programs in the Flash Memory and then upload the new ones.  

 

3) 

When the uploading is completed, initiate file upgrade on the switch. 

Use the boot boot-loader command to specify the downloaded program as 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 general). 

Compared with FTP, another file transmission protocol, TFTP has no 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 sends 

a request to the TFTP server and then receives data from it and sends 

acknowledgement to it. To upload a file, the client sends a request to the TFTP server 

and then transmits data to it and receives the acknowledgement from it. TFTP transmits 

files in two modes, binary mode for program files and ASCII mode for text files.  

The administrator needs to configure the IP addresses of TFTP client and server before 

configuring TFTP, and makes sure that the route between the client and server is 

reachable. 

The switch can only function as a TFTP client.
