ExtremeWare Software 7.3.0 Command Reference Guide 2107
A
Configuration and Image Commands
This appendix 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
The switch software image 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, 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
to which configuration 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.
