KB ID 0001003 Dtd 29/09/14


If you manage to stuff up your firewall, or you have just done some testing and want to revert back to 'as new' here is how to do it.

SRX Firewall


1. Connect to the firewall either by console cable or via SSH, go to CLI mode then configuration mode.

PeteL@Petes-SRX> cli

PeteL@Petes-SRX> configure  Entering configuration mode

[edit]  PeteL@Petes-SRX#

2. Load factory defaults, at this point you cannot commit/save the configuration unless you set a password, so do that next.

[edit]  PeteL@Petes-SRX# set system root-authentication plain-text-password  New password: Password123  Retype new password: Pasword123

[edit]  PeteL@Petes-SRX#

3. Save the changes then reboot.

[edit]  PeteL@Petes-SRX# commit and-quit

commit complete  Exiting configuration mode

PeteL@Petes-SRX> request system reboot  Reboot the system ? [yes,no] (no) yes

Shutdown NOW!  [pid 1904]


*** FINAL System shutdown message from root@FW-01 ***

System going down IMMEDIATELY

Reset To Factory Settings if the SRX is part of a Chassis Cluster (is in Failover mode)

1. If the firewall is part of the Chassis cluster then you need to the following before you can carry out the procedure above.

PeteL@Petes-SRX> set chassis cluster disable reboot

For cluster-ids greater than 15 and when deploying more than one  cluster in a single Layer 2 BROADCAST domain, it is mandatory that  fabric and control links are either connected back-to-back or  are connected on separate private VLANS.

{primary:node0}  PeteL@Petes-SRX>

*** FINAL System shutdown message from root@FWA ***

System going down IMMEDIATELY

Completely Wipe the Juniper SRX

Alternatively you can also do the following.

root> 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

warning: zeroizing re0
