archive download-sw
The BOOT environment variable is changed to point to the new software image on the flash: file system.
Image names are case sensitive; the image file is provided in tar format.
Command Modes Privileged EXEC
Command History
Usage Guidelines The /imageonly option removes the HTML files for the existing image if the existing image is being
removed or replaced. Only the Cisco IOS image (without the HTML files) is downloaded.
Using the /safe or /leave-old-sw option can cause the new image download to fail if there is insufficient
flash memory. If leaving the software in place prevents the new image from fitting in flash memory due
to space constraints, an error results.
If you used the /leave-old-sw option and did not overwrite the old image when you downloaded the new
one, you can remove the old image by using the delete privileged EXEC command. For more
information, see the “delete” section on page 2-66.
Use the /overwrite option to overwrite the image on the flash device with the downloaded one.
If you specify the command without the /overwrite option, the download algorithm verifies that the new
image is not the same as the one on the switch flash device. If the images are the same, the download
does not occur. If the images are different, the old image is deleted, and the new one is downloaded.
After downloading a new image, enter the reload privileged EXEC command to begin using the new
image, or specify the /reload or /force-reload option in the archive download-sw command.
Examples This example shows how to download a new image from a TFTP server at 172.20.129.10 and to
overwrite the image on the switch:
Switch# archive download-sw /overwrite tftp://172.20.129.10/test-image.tar
This example shows how to download only the software image from a TFTP server at 172.20.129.10 to
the switch:
Switch# archive download-sw /imageonly tftp://172.20.129.10/test-image.tar
This example shows how to keep the old software version after a successful download:
Switch# archive download-sw /leave-old-sw tftp://172.20.129.10/test-image.tar
