Working with Software Images
Note
To avoid an unsuccessful download, use the
archive download-sw /safe
command, which downloads
the image first and does not delete the current running version until the download succeeds.
The download algorithm verifies that the image is appropriate for the bridge 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.
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 system boot path 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 entering 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.
Uploading an Image File by Using TFTP
You can upload an image from the bridge to a TFTP server. You can later download this image to the
bridge or to another bridge of the same type.
Caution
For the download and upload algorithms to operate properly, do
not
rename image directories.
Beginning in privileged EXEC mode, follow these steps to upload an image to a TFTP server:
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 17-20
.
Step 1
Log into the bridge through a Telnet session.
Step 2
archive upload-sw
tftp:
[[
//
location
]
/
directory
]
/
image-name
.tar
Upload the currently running bridge 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.
