How to Clear Entire Configuration of your Juniper Device

If you have a Juniper device that needs to be sent to RMA or you are just putting it to some other use on your network, you will probably want to completely clear the configuration on it.

There are different ways to do it for different purpose.

If you want to securely wipe all data from this device and make it completely like when you received it from the store then next command is the right one to use:

[email protected]> request system zeroize

This one will completely wipe your Juniper device and clear configuration together with all data from flash.

If you want to just load a clean config but you want to keep previous log files, configurations and other stuff written on device flash, you should run this one:

[email protected]# load factory-default

It will just load clean config file without any user config on it and you are ready to create new configuration on your device.
Example on how would “request system zeroize” process look like on Juniper SRX300:

[email protected]> request system zeroize    
warning: System will be rebooted and may not boot without configuration
Erase all data, including configuration and log files? [yes,no] (no) yes
