Appendix B Working with the Cisco IOS File System, Configuration Files, and Software Images

Working with Software Images

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.

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 image 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 FTP

You can upload an image from the switch to an FTP server. You can later download this image to the same switch or to another switch of the same type.

Use the upload feature 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 FTP server:

 

Command

Purpose

Step 1

 

 

 

Verify that the FTP server is properly configured by referring

 

 

to the “Preparing to Download or Upload a Configuration

 

 

File By Using FTP” section on page B-14.

Step 2

 

 

 

Log into the switch through the console port, the Ethernet

 

 

management port, or remotely through a Telnet session by

 

 

using the IP address of the Ethernet management port.

Step 3

 

 

configure terminal

Enter global configuration mode.

 

 

This step is required only if you override the default remote

 

 

username or password (see Steps 4, 5, and 6).

Step 4

 

 

ip ftp username username

(Optional) Change the default remote username.

Step 5

 

 

ip ftp password password

(Optional) Change the default password.
