Release Information

Command introduced before Junos OS Release 9.0.

Command introduced in Junos OS Release 11.2 for EX Series devices.

Option media added in Junos OS Release 11.4 for EX Series devices.

Command introduced in Junos OS Release 12.2 for MX Series devices.

Option local added in Junos OS Release 14.1.


Remove all configuration information on the Routing Engines and reset all key values. If the device has dual Routing Engines, the command is broadcast to all Routing Engines on the device. The command removes all data files, including customized configuration and log files, by unlinking the files from their directories. The command removes all user-created files from the system including all plain-text passwords, secrets, and private keys for SSH, local encryption, local authentication, IPsec, RADIUS, TACACS+, and SNMP.

This command reboots the device and sets it to the factory default configuration. After the reboot, you cannot access the device through the management Ethernet interface. Log in through the console as root and start the Junos OS CLI by typing cli at the prompt.

To completely erase user-created data so that it is unrecoverable, use the media option in non FIPS mode.
