How to clear an ASA`s configuration | |
==================================== | |
1. Reboot the device | |
2. On boot hit `escape` so that you break the normal startup process and enter | |
ROMMON. | |
3. Change the current confreg so that you can bypass the current startup config | |
sing the command: | |
rommon #1>confreg 0x41 | |
4. Reset the appliance with the boot command, | |
rommon #2>boot | |
5. You will then be presented with the ScreenOS CLI and the ASA having a completely clear config. Run the commands : | |
ciscoasa > en [when asked for password just press enter] | |
ciscoasa # conf t | |
ciscoasa (config)# config-register 0x01 | |
ciscoasa (config)# copy run start | |
