How to Factory Reset F5 BIG-IP Device?

--> I would recommend you have the physical access to the F5 device using console before implementing the reset of the F5 device.

--> Resetting the BIG-IP LTM to factory default does the following:

1) Removes all BIG-IP local traffic configuration objects

2) Removes all BIG-IP network configuration objects

3) Removes all non-system maintenance user accounts

4) Removes system maintenance user account passwords ( root and admin)

5) Removes BIG-IP module data and policies

6) Resets the hostname to the default value

7) Resets the local trust domain

8) Retains the management ip address

9) Retains the BIG-IP license file

10) Retains the files in /shared partition

11) Retains manually-modified bigdb database variables

Step1: To restore the BIG-IP configuration to factory default settings:

#tmsh

# load /sys config default

reset the system configuration to factory defaults ? (y/n) :y

Step2: Save the configuration on F5 BIG-IP System:

# save /sys config partitions all

Step3: Remove the BIND configuration

#config

# cp /usr/share/defaults/fs/var/named/config/named.conf.rpmbackup /var/named/config/named.conf

cp: overwrite 'var/named/config/named.conf' ? y

Step4: Removed trusted certificates from the F5 device

#config

# rm /config/gtm/server.crt

rm: remove regular empty file '/config/gtm/server.crt'? y

Step5: Remove zone data from F5 device

# rm /var/named/config/namedb/*

rm: remove regular empty file '/var/named/config/namedb/dummy_zone_file.db'? y

Step6:Reboot the F5 BIG-IP Device:

#config

#full_box_reboot
