Working with Software Images
Downloading an Image File By Using TFTP
You can download a new image file and replace the current image or keep the current image.
Beginning in privileged EXEC mode, follow Steps 1 through 3 to download a new image from a TFTP server and overwrite
the existing image. To keep the current image, go to Step 3.
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 running image, the download process stops, and an error message is displayed.
Command Purpose
1. Copy the image to the appropriate TFTP
directory on the workstation. Make sure that
the TFTP server is properly configured; see the
Preparing to Download or Upload an Image File
By Using TFTP, page 1015
.
2. Log into the switch through the console port or
a Telnet session.
3. archive download-sw /overwrite /reload
tftp:
[[ // location ] / directory ] / image-name .tar
Downloads the image file from the TFTP server to the switch, and
overwrite the current image.

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-name .tar , specify the directory (optional)
and the image to download. Directory and image names are
case sensitive.
4. archive download-sw /leave-old-sw /reload
tftp:
[[ // location ] / directory ] / image-name .tar
Downloads the image file from the TFTP server to the switch, and
keep the current image.

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.
