To do this, you will need to access the device over the network or through the console and issue one of the following commands (not all commands are supported on all Cisco devices):
- write erase
- erase nvram:
- erase startup-config
Once you execute one of the commands above, you will need to reload the device. Here is an example:
R1#write erase Erasing the nvram filesystem will remove all configuration files! Continue? [confirm] [OK] Erase of nvram: complete %SYS-7-NV_BLOCK_INIT: Initialized the geometry of nvram R1#reload Proceed with reload? [confirm]
