Appendix B Working with the Cisco IOS File System, Configuration Files, and Software Images
Working with Software Images
The download algorithm verifies that the image is appropriate for the switch model and that enough
DRAM is present, or it aborts the process and reports an error. If you specify the /overwrite option, the
download algorithm removes the existing image on the flash device, whether or not it is the same as the
new one, downloads the new image, and then reloads the software.
Step 7
archive download-sw /allow-feature-upgrade
[/directory] /overwrite /reload
tftp:[[//location]/directory]/image-name1.tar
[image-name2.tar image-name3.tar
image-name4.tar]
(Optional) Download the image files from the FTP server to
the sw
itch, and overwrite the current image.
• The /allow-feature-upgrade option allows installation of
a software image with a different feature set.
• (Optional) The /directory option specifies a directory for
the images.
• The /overwrite option overwrites the software image in
flash memory with the downloaded image.
• The /reload option reloads the system after downloading
the image unless the configuration has been changed and
not been saved.
• For //username[:password], specify the username and
password; these must be associated with an account on the
FTP server. For more information, see the “Preparing to
Download or Upload an Image File By U
sing FTP”
section on page B-31.
• For @location, specify the IP address of the FTP server.
• For /directory/image-name1.tar
[/directory/image-name2.tar image-name3.tar
image-name4.tar], specify the directory (optional) and the
images to download. Directory and image names are case
sensitive.
Step 8
archive download-sw [/directory] /leave-old-sw
/reload
tftp:[[//location]/directory]/image-name1.tar
[image-name2.tar image-name3.tar
image-name4.tar]
(Optional) Download the image files from the FTP server to
the sw
itch, and keep the current image.
• (Optional) The /directory option specifies a directory for
the images.
• The /leave-old-sw option keeps the old software version
after a download.
• The /reload option reloads the system after downloading
the image unless the configuration has been changed and
not been saved.
• For //username[:password], specify the username and
password. These must be associated with an account on
the FTP server. For more information, see the “Preparing
to Download or Upload an I
mage File By Using FTP”
section on page B-31.
• For @location, specify the IP address of the FTP server.
• For directory/image-name.tar, specify the directory and
the image to download. Directory and image names are
case sensitive.
