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

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.
