Configuration and Image Commands
This chapter describes the following commands:
• Commands related to downloading and using a new switch software image
• Commands related to saving, uploading, and downloading switch configuration information
• Commands related to the BootROM and switch rebooting
• Commands related to downloading and using a new Altitude 300 Access Point software image
The switch software image file contains the executable code that runs on the switch. An image comes
preinstalled from the factory. The image can be upgraded by downloading a new version from a Trivial
File Transfer Protocol (TFTP) server on the network.
A switch can store up to two images, a primary and a secondary image. You can download a new
image into either one of these areas, and you can select which image will load on the next switch
reboot.
The configuration is the customized set of parameters that you have selected to run on the switch. As
you make configuration changes, the new settings are stored in run-time memory. To retain the settings,
and have them load when you reboot the switch, you must save the configuration to nonvolatile
storage.
A switch can store two different configurations, a primary and a secondary configuration. You can select
the configuration area to which you want the changes saved, and which configuration will be used on
the next switch reboot.
The BootROM initializes certain important switch variables during the switch boot process. In specific
situations, the BootROM can be upgraded by download from a TFTP server on the network.
The Altitude 300 Access Point (AP) is shipped from the factory with pre-installed bootstrap and boot
loader images. You can upgrade it with newer versions of bootstrap, bootloader, or runtime images
from a TFTP server on the network by using image-configuration commands.
