CAUTION:
•
When you back up a file to the server, the existing file with the same name on the server, if any, will be
replaced without a prompt.
• The operations mentioned above are to be performed in user view.
• You can modify the backup configuration file with a text editor and then download the modified file to
upgrade the configuration. The upgrade takes effect upon system reboot. Likewise, you can download
the system software image file to the switch and overwrite the existing main system software image file
to upgrade the system software image file.
Upgrading a system software image file through an
Ethernet port by using FTP
If the system software image file to be downloaded has a large size, you can use the File Transfer Protocol
(FTP) to save the software maintenance time.
FTP is an application-layer TCP/IP protocol used for file transfer between server and client. It provides
reliable, connection-oriented data transfer service over TCP.
You can upgrade a system software image file by using FTP in the following ways:
• Through the BootWare menu. In this approach, the switch must serve as an FTP client.
• At the CLI. In this approach, the switch can serve as either an FTP server or an FTP client.

• The switch servers as an FTP client, and the PC as the FTP server.
• Connect the Ethernet port GigabitEthernet 1/0/1 of the switch to the PC by using a crossover
Ethernet cable, and configure IP addresses for the Ethernet port of the switch and the PC, which must
be on the same network segment so that the switch and the PC can communicate with each other.
