Product and Software: This article applies to all Aruba controllers and ArubaOS versions.
Sometimes a switch configuration file may get corrupted. When this happens, the switch boots, loads the configuration file, and then the switch may not return a prompt or it reboots again. To bypass loading, the configuration 'cfgfile' parameter can be set in the controller boot options.
When this option is set, the switch bypasses the configuration file and instead loads the 'factory-default.cfg' file. This initiates the switch setup dialog, which prompts the user to go through the basic switch configuration. After switch setup is complete, the switch boots with the new settings and the user can restore the configuration from the backup file.
Step 1: To stop the boot process and enter 'cpboot' mode, press Enter when prompted. Issue the 'printenv' command to list current settings.

Step 2: Use the 'setenv' command to set the 'cfgfile' parameter to bypass the configuration file. As long as 'cfgfile' is set to any value, it bypasses the configuration file. In this example, 'cfgfile' is set to 'default.cfg'. Save the settings by issuing the 'saveenv' command and issue the 'printenv' command to verify settings. After settings have been verified, issue the 'reset' command to boot the switch.

cpboot> reset
Step 3: After the 'reset' command, the switch reboots and the start setup dialog is displayed. In this example, all defaults are accepted. Select the country code correctly, because it cannot be changed in the switch configuration. When setup dialog is complete, the switch reboots.
