Appendix B
Working with the Cisco IOS File System, Configuration Files, and Software Images
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.
Note
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.

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.
Before you begin downloading or uploading an image file by using FTP, do these tasks:

The username specified in the archive download-sw or archive upload-sw privileged EXEC
command if a username is specified.
The username set by the ip ftp username username global configuration command if the command
is configured.
Anonymous.
The password specified in the archive download-sw or archive upload-sw privileged EXEC
command if a password is specified.
The password set by the ip ftp password password global configuration command if the command
is configured.
The switch forms a password named username@switchname.domain. The variable username is the
username associated with the current session, switchname is the configured hostname, and domain
is the domain of the switch.
Ensure that the switch has a route to the FTP server. The switch and the FTP server must be in the
same subnetwork if you do not have a router to route traffic between subnets. Check connectivity to
the FTP server by using the ping command.
