Connect the serial console breakout adapter cable to the AP Ethernet port and your PC/Laptop
Power on the AP and get into apboot mode. You’ll see the option to go into AP boot mode when the AP is booting.
From the apboot prompt, enter the following commands
apboot> reset or boot
#write erase all

Do you really want to restart the system(y/n): y
There are 3 methods of restoring system defaults.
Restoring Factory Defaults:
This option will reset all system settings, including the Setup Console password. To restore factory defaults, use the following CLI command:
SGOS# restore-defaults factory-defaultsRetaining Console Settings:
This option will retain settings like console username and password, front panel pin number, console enable password, SSH host keys, keyrings used by secure console services, RIP configurations, IP address, MTU size, TCP round trip time, and static routes. To restore defaults while retaining console settings, use the following CLI command:
SGOS# restore-defaults keep-consoleRestoring Defaults through the Management Console:
If you restore defaults through the Management Console, you will lose most settings because there is no “keep console” option. To restore defaults through the Management Console, select Maintenance > General, click the Restore button, then click OK to confirm.
that only delete config but not vlan.
vlan in vlan.dat
# delete flash:vlan.dat
Delete filename [vlan.dat]?
System configuration has been modified. Save? [yes/no]: n
Proceed with reload? [confirm]
The difficulty with clearing a switch that is cabled to other switches is removing the VLANs. When the switch
is finished reloading, it is possible for it to relearn VLANs from another connected switch that is in VTP server
or client mode.
To determine if the VLANs have been relearned, use the show vlan command.
Switch# show vlan brief
However, if the show vlan command displays nondefault VLANs after you have deleted the vlan.dat file,
your switch has learned the VLANs dynamically from another switch.
Switch# show vlan brief

You are about to reset the system back to factory default configuration.
* The new CLI password will be ‘admin’.
* All network interfaces will get up with the factory default configuration.
* Appliance registration will NOT be affected by this.
* Other firmware’s configuration will NOT be affected by this.
* Post reset, this will reboot the system.

You may occasionally need to remove the current BIG-IP configuration and restore the system to the factory default setting. To do so, you can use the tmsh load sys config default command. The tmsh load sys config default command saves the currently-running configuration to the /var/local/scf/backup.scf file, and then loads the /defaults/defaults.scf file to restore the configuration to factory default settings.
Note: The tmsh load sys config default command retains certain configuration elements such as those that are necessary to maintain basic administrative functionality.
When you restore the BIG-IP configuration to factory default settings, the system performs the following tasks:
Removes all BIG-IP local traffic configuration objects
Removes all BIG-IP network configuration objects
Removes all non-system maintenance user accounts
Retains the management IP address
Removes system maintenance user account passwords (root and admin)
Retains the BIG-IP license file
Retains files in the /shared partition
Retains manually-modified bigdb database variables
To restore the BIG-IP configuration to the factory default setting, perform the following procedure.
Restoring the BIG-IP configuration to the factory default setting
Impact of procedure: This procedure removes all BIG-IP local traffic and network configuration objects.
scp /config/bigip.license to your pc first
(tmos)#load sys config default
Reset the system configuration to factory defaults? (y/n)y
(tmos)#save sys config partitions all
To restore config
(tmos)#load sys ucs test.ucs no-license
# execute factoryreset
The user can restore the factory default configuration either on the switch itself, or through the switch console.
To execute the factory default reset on the switch, perform these steps:
-Using pointed objects, simultaneously press both the Reset and Clear buttons on the front of the switch.
-Continue to press the Clear button while releasing the Reset button.
-When the Self Test LED begins to blink, release the Clear button.
-The switch will then complete its self test and begin operating with its configuration restored to the factory default settings.
To restore the factory default configuration using the console, execute the erase startup-config command from the console command prompt.
