How do I reset my switch to factory-default configuration via CLI commands?

If you would like to reset the device to the factory default configuration, the simplest way is to log in to CLI mode. For GS/XGS. NOT for NSW.

Please use Putty on Windows or a similar SSH client to login into your switch. You will need to type in the IP of the switch as the client. You will get asked to enter the username and password for your switch. After the login, please enter the following commands:

Switch# erase running-config
Switch# write memory

This will bring your switch back to factory default.
