Copying Image Files By Using FTP

You can download a switch image from an FTP server or upload the image from the switch to an FTP
server.
You download a switch image file from a server to upgrade the switch software. You can overwrite the
current image with the new one or keep the current image after a download.
You upload a switch image file to a server for backup purposes. You can use this uploaded image for
future downloads to the switch or another switch of the same type.

Preparing to Download or Upload an Image File By Using FTP

You can copy images files to or from an FTP server.
The FTP protocol requires a client to send a remote username and password on each FTP request to a
server. When you copy an image file from the switch to a server by using FTP, the Cisco IOS software
sends the first valid username in this list:
•
•
•
The switch sends the first valid password in this list:
•
•
•
The username and password must be associated with an account on the FTP server. If you are writing to
the server, the FTP server must be properly configured to accept the FTP write request from you.
Use the ip ftp username and ip ftp password commands to specify a username and password for all
copies. Include the username in the archive download-sw or archive upload-sw privileged EXEC
command if you want to specify a username only for that operation.
If the server has a directory structure, the image file is written to or copied from the directory associated
with the username on the server. For example, if the image file resides in the home directory of a user
on the server, specify that user's name as the remote username.
