Working with the Cisco IOS File System, Configuration Files, and Software Images
Working with Software Images
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.
Use the upload feature only if the web management pages associated with the embedded Device Manager have been
installed with the existing image.
Beginning in privileged EXEC mode, follow these steps to upload an image to a TFTP server:
Command
1.
Make sure the TFTP server is properly
configured; see the
Upload an Image File By Using TFTP,
page
1015.
2.
Log into the switch through the console port or
a Telnet session.
3.
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 these files in order:
info, the Cisco IOS image, and the web management files. After these files are uploaded, the upload algorithm creates
the tar file format.
Caution:
For the download and upload algorithms to operate properly, do not rename image names.
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
Purpose
Uploads 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.
