Revert to the EX Series Switch Factory-Default Conguraon Using the request system

zeroize Command

The request system zeroize command is a standard Junos OS operaonal mode command that removes all

conguraon informaon and resets all key values. The operaon unlinks all user-created data les,

including customized conguraon and log les, from their directories. The switch then reboots and

reverts to the factory-default conguraon.

To completely erase user-created data so that it is unrecoverable, use the request system zeroize media

command.

CAUTION: Before issuing request system zeroize, use the request system snapshot command

to back up the les currently used to run the switch to a secondary device. Using the

zeroize command will destroy Junos and OAM parons, and the switch may not boot.

To recover from a failed soware installaon, see Recovering from a Failed Soware

Installaon.

To revert to the factory-default conguraon by using the request system zeroize command:

user@switch>request system zeroize warning: System will be rebooted and may not boot without

configuration

Erase all data, including configuration and log files?. In case of Dual RE system, both

Routing Engines will be zeroized [yes,no] (no)

2. Type yes to remove conguraon and log les and revert to the factory-default conguraon.

NOTE: The auto-image-upgrade statement is added under the [edit chassis] hierarchy level when

you use this procedure. The automac image upgrade feature is then available on the switch.

Revert to the EX Series Switch Factory-Default Conguraon Using the load factory-

default Command

The load factory-default command is a standard Junos OS conguraon command that replaces the

current acve conguraon with the factory-default conguraon except the root password seng. By

default, the root password is not set; you must set it to commit the new conguraon in this procedure.

If you want to run the EZsetup script to complete the inial conguraon of the switch aer you revert

to the factory-default conguraon, do not use the load factory-default command. Instead, revert using

the request system zeroize command. If you use the load factory-default command to revert to the factory-

default conguraon, the conguraon for the root password is retained and the EZsetup script will not
