Cisco Systems 3750E manual Uploading an Image File By Using RCP

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.

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 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-swkeyword), you can remove it by entering the delete /force /recursive filesystem:/file-urlprivileged 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
Step 1
		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 B-31.
Step 2
		Log into the switch through the console port, the Ethernet
		management port, or a Telnet session.
Step 3
	configure terminal	Enter global configuration mode.
		This step is required only if you override the default remote
		username (see Steps 4 and 5).
Step 4
	ip rcmd remote-username username	(Optional) Specify the remote username.
