Chapter 8 Managing Controller Software and Configurations
Saving Configurations
Step 8 The controller now has the code update in active volatile RAM, but you must enter reset system to save
the code update to non-volatile NVRAM and reboot the Cisco Wireless LAN Controller:
reset system
The system has unsaved changes.
Would you like to save them now? (y/n) y
The controller completes the bootup process.
Saving Configurations
Controllers contain two kinds of memory: volatile RAM and NVRAM. At any time, you can save the
configuration changes from active volatile RAM to non-volatile RAM (NVRAM) using one of these
commands:
• Use the save config command. This command saves the configuration from volatile RAM to
NVRAM without resetting the controller.
• Use the reset system command. The CLI prompts you to confirm that you want to save
configuration changes before the controller reboots.
• Use the logout command. The CLI prompts you to confirm that you want to save configuration
changes before you log out.
Clearing the Controller Configuration
Follow these steps to clear the active configuration in NVRAM.
Step 1 Enter clear config and enter y at the confirmation prompt to confirm the action.
Step 2 Enter reset system. At the confirmation prompt, enter n to reboot without saving configuration changes.
When the controller reboots, the configuration wizard starts automatically.
Step 3 Follow the instructions in the “Using the Configuration Wizard” section on page 4-2 to complete the
initial configuration.
Erasing the Controller Configuration
Follow these steps to reset the controller configuration to default settings:
Step 1 Enter reset system. At the confirmation prompt, enter y to save configuration changes to NVRAM. The
controller reboots.
Step 2 When you are prompted for a username, enter recover-config to restore the factory default
configuration. The controller reboots and the configuration wizard starts automatically.
