Cisco Systems 3560 사용자 설명서

This section describes how to archive (download and upload) software image files, which contain the 
system software, the Cisco IOS code, and the embedded device manager software.

Instead of using the copy privileged EXEC command or the archive tar privileged EXEC command, we 
recommend using the archive download-sw and archive upload-sw privileged EXEC commands to 
download and upload software image files. .

You can download a switch image file from a TFTP, FTP, or RCP server to upgrade the switch software. 
If you do not have access to a TFTP server, you can download a software image file directly to your PC 
or workstation by using a web browser (HTTP) and then by using the device manager or Cisco Network 
Assistant to upgrade your switch. For information about upgrading your switch by using a TFTP server 
or a web browser (HTTP), see the release notes.

You can replace the current image with the new one or keep the current image in flash memory after a 
download.

You can use the archive download-sw /allow-feature-upgrade privileged EXEC command to allow 
installation of an image with a different feature set, for example, upgrading from the IP base image to 
the IP services image. Beginning in this release, you can also use the boot auto-download-sw global 
configuration command to specify a URL to use to get an image for automatic software upgrades. 

You upload a switch image file to a TFTP, FTP, or RCP server for backup purposes. You can use this 
uploaded image for future downloads to the same switch or to another of the same type.

The protocol that you use depends on which type of server you are using. The FTP and RCP transport 
mechanisms provide faster performance and more reliable delivery of data than TFTP. These 
improvements are possible because FTP and RCP are built on and use the TCP/IP stack, which is 
connection-oriented.
