Working with Software Images
If you specify the /leave-old-sw, the existing files are not removed. If there is not enough room to install
the new image an keep the running image, the download process stops, and an error message is
displayed.
The algorithm installs the downloaded image onto the system board flash device (flash:). The image is
placed into a new directory named with the software version string, and the BOOT environment variable
is updated to point to the newly installed image.
If you kept the old software during the download process (you specified the /leave-old-sw keyword), you
can remove it by enterin g 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 software image. All the files in the directory and the directory are removed.
Caution For the download and upload algorithms to operate properly, do not rename image names.
Uploading an Image File By Using RCP
You can upload an image from the switch to an RCP server. You can later download this image to the
same switch or to another switch of the same type.
The upload feature should be used only if the web management pages associated with the embedded
device manager have been installed with the existing image.
Beginning in privileged EXEC mode, follow these steps to upload an image to an RCP server:
Command Purpose
Step1 Verify that the RCP server is properly configured by
referring to the “Preparing to Download or Upload an Image
File By Using RCP” section on page C-36.
Step2 Log into the switch through the console port or a Telnet
session.
Step3 configure terminal Enter global configuration mode.
This step is required only if you override the default remote
username (see Steps 4 and 5).
Step4 ip rcmd remote-username username (Optional) Specify the remote username.
