Problem

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.

Solution

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

[box] login: PeteL
Password: ************

— JUNOS 12.1X47-D10.4 built 2014-08-14 22:21:50 UTC

PeteL@Petes-SRX> cli

PeteL@Petes-SRX> configure
Entering configuration mode

[edit]
PeteL@Petes-SRX#

[/box]

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

[box]

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

[edit]
PeteL@Petes-SRX#

[/box]

3. Save the changes then reboot.

[box] [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]

PeteL@Petes-SRX>

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

System going down IMMEDIATELY

[/box]

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.

[box]

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

[/box]

Completely Wipe the Juniper SRX

Alternatively you can also do the following.

[box]

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

root>

[/box]
