Appendix 1 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.
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 is
displayed.
Step 3
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 TFTP server to the
switch, and overwrite the current image.
• The /allow-feature-upgrade option allows installation of a
software images with different feature sets.
• (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 //location, specify the IP address of the TFTP 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 4
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 images file from the TFTP server to the
switch, 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 //location, specify the IP address of the TFTP 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.
