Appendix B Working with the Cisco IOS File System, Configuration Files, and Software Images
Working with 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. For switch stacks, the
archive download-sw
and
archive
upload-sw
privileged EXEC commands can only be used through the stack master. Software images
downloaded to the stack master are automatically downloaded to the rest of the stack members.
To upgrade a switch with an incompatible software image, use the
archive copy-sw
privileged EXEC
command to copy the software image from an existing stack member to the incompatible switch. That
switch automatically reloads and joins the stack as a fully functioning member.

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 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 switch 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 switch forms a password named
. The variable
username
is the
username associated with the current session,
switchname
is the configured hostname, and
domain
is the domain of the switch.
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.
