Appendix B Working with the Cisco IOS File System, Configuration Files, and Software Images
Note If the flash device has sufficient space to hold two images and you want to overwrite one of these images
with the same version, you must specify the /overwrite option.
If you specify the /leave-old-sw, the existing files are not removed. If there is not enough space to install
the new image and keep the current running image, the download process stops, and an error message
appears.
The algorithm installs the downloaded image on the system board flash device (flash:). The image is
placed into a new directory named with the software version string, and the BOOT environment variable
is updated to point to the newly installed image.
If you kept the old image during the download process (you specified the /leave-old-sw keyword), you
can remove it by entering the delete /force /recursive filesystem:/file-url privileged EXEC command.
For filesystem, use flash: for the system board flash device. For file-url, enter the directory name of the
old image. All the files in the directory and the directory are removed.
Caution For the download and upload algorithms to operate properly, do not rename image names.
Uploading an Image File By Using TFTP
You can upload an image from the switch to a TFTP server. You can later download this image to the
switch or to another switch of the same type.
Beginning in privileged EXEC mode, follow these steps to upload an image to a TFTP server:
Command
Step 1
Step 1
Step 2
archive upload-sw
tftp:[[//location]/directory]/image-name.tar
The archive upload-sw privileged EXEC command builds an image file on the server by uploading the
the info file and the Cisco IOS image file. After these files are uploaded, the upload algorithm creates
the tar file format.
For the download and upload algorithms to operate properly, do not rename image names.
Caution
78-15870-01
Purpose
Make sure the TFTP server is properly configured; see the
"Preparing to Download or Upload an Image File By Using TFTP"
section on page B-21.
Log into the switch through the console port or a Telnet session.
Upload the currently running switch image to the TFTP server.
• For //location, specify the IP address of the TFTP server.
• For /directory/image-name.tar, specify the directory (optional)
and the name of the software image to be uploaded. Directory
and image names are case sensitive. The image-name.tar is the
name of the software image to be stored on the server.
