Restoring the Factory Default Settings
Restoring the factory-default settings deletes the existing NVRAM settings, startup configuration, and all configured settings such as,
stacking or fanout.
To restore the factory default settings, use the restore factory-defaults stack-unit {stack—unit—number | all}
{clear-all | nvram | bootvar} command in EXEC Privilege mode.
CAUTION:
There is no undo for this command.
Important Points to Remember
• When you restore all the units in a stack, these units are placed in standalone mode.
• When you restore a single unit in a stack, only that unit is placed in standalone mode. No other units in the stack are affected.
• When you restore the units in standalone mode, the units remain in standalone mode after the restoration.
• After the restore is complete, the units power cycle immediately.
The following example illustrates the restore factory-defaults command to restore the factory default settings.

Restoring Factory Default Environment Variables
The Boot line determines the location of the image that is used to boot up the chassis after restoring factory default settings. Ideally,
these locations contain valid images, using which the chassis boots up.
When you restore factory-default settings, you can either use a flash boot procedure or a network boot procedure to boot the switch.
