Copying Image Files by Using FTP
You can download a WMIC image from an FTP server or upload the image from the WMIC to an FTP
server.
You download a WMIC image file from a server to upgrade the WMIC software. You can overwrite the
current image with the new one or keep the current image after a download.
You upload an WMIC image file to a server for backup purposes. You can use this uploaded image for
future downloads to the WMIC or another device 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 WMIC to a server by using FTP, the Cisco IOS software
sends the first valid username in this list:
• 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 WMIC sends the first valid password in this list:
• 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 WMIC forms a password named [e-mail]. The variable username is the
username associated with the current session, apname is the configured host name, and domain is
the domain of the WMIC.
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, perform these tasks:
• Ensure that the WMIC has a route to the FTP server. The WMIC and the FTP server must be in the
same subnetwork if you do not have a router to route traffic between subnets. Verify connectivity to
the FTP server by using the ping command.
