45.4.1 Using the Switch as an FTP Client to Implement the Remote Upgrade
I. Network requirements
The user logs into the switch using Telnet, downloads the application from the FTP
server to the flash memory of the switch, and implements remote upgrade using the
right commands.
The switch serves as an FTP client and the remote PC as an FTP server. The
configuration on the FTP server is as follows: an FTP user is configured with the name
switch, the password hello and the read & write authority over the Switch root directory
on the PC. The IP address of a VLAN interface on the switch is 1.1.1.1, and the IP
address of the PC is 2.2.2.2. The switch and PC are reachable with each other.
The switch applications switch.app and boot.app are stored on the PC. Using FTP,
these files can be downloaded from the remote FTP server to the switch.
