Appendix B 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 enterin g 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:
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 file format.
Caution For the download and upload algorithms to operate properly, do not rename image names.
Command Purpose
Step 1 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-28.
Step 2 Log into the switch through the console port, the Ethernet
management port, or a Telnet session.
Step 3 archive upload-sw
tftp:[[//location]/directory]/image-name.tar 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.
