Reimage Cisco 1010 ASA to FTD

KB ID 0001677


Sorry it’s taken me a while to get round to this, every time I do some work on the firewall I need to kill the internet at home, and I’ve got a wife and two daughters, who live online! So if you follow the site you will know I’ve got a Cisco Firepower 1010 device, and I’ve been looking at it running the ASA code.

Now here’s how to ‘re-image’ the device with the FTD (Firepower Threat Defence) operating system.

Warning this can take a while, if you are performing this in production equipment, plan in at least a couple of hours downtime.


Firstly this is a lot easier than it was on the old ASA 5500-x platform, If you have ever updated the OS on a Cisco ASA, then the process is pretty much the same.

Before proceeding, you need to unregister the firewall from its Smart Licence (assuming it’s registered correctly). You can do this with the following command;

licence smart deregister

Or from the ASDM;

Then connect the firewall via console cable, I’m going to copy the operating system in from a TFTP server on my mac, (you can use FTP or HTTP if you prefer).

Petes-ASA# copy tftp flash

Address or name of remote host []?

Source filename []? cisco-ftd-fp1k.6.6.0-90.SPA

Destination filename [cisco-ftd-fp1k.6.6.0-90.SPA]? {Enter}
Accessing tftp://!!!!!!!!!!!!!!!!
Verifying file disk0:/cisco-ftd-fp1k.6.6.0-90.SPA...

Writing file disk0:/cisco-ftd-fp1k.6.6.0-90.SPA...

1097176240 bytes copied in 331.300 secs (3314731 bytes/sec)

Now we simply need to set the image as the primary boot OS.

Petes-ASA# configure terminal
ciscoasa(config)# boot system disk0:/cisco-ftd-fp1k.6.6.0-90.SPA

The system is currently installed with security software package, which has:
   - The platform version:
   - The CSP (asa) version:
Preparing new image for install...
Image download complete (Successful unpack the image).
   If you proceed, the system will be re-imaged and then reboot automatically.
   All existing configuration will be lost and the default configuration will be applied.
Installation of version 6.6.0-90 will do the following:
   - upgrade to the new platform version
   - upgrade to the CSP FTD version 6.6.0-90
Do you want to proceed? [confirm] {Enter}

The firewall will install the new OS then reboot itself, it will take a while, be patient! Once rebooted the FTD software will ask you to login, the default username and password is admin and Admin123, upon logging in, you are asked to change the password.

firepower login: admin
Password: Admin123
Successful login attempts for user 'admin' : 1

Now you can carry out an initial configuration of the Firepower. 

firepower# connect ftd

Here I set the basic IPv4 settings, and tell the firewall it will be managed locally via FDM (Firepower Device Manager), that’s the web management interface on the device, rather than FMC (Firepower Management Center) a separate management appliance.

At this point I reboot the unit, but be prepared, it can take a LONG time before it comes back online, (wait at least 40 minutes). 

IMPORTANT you have configured the IP address on the MANAGEMENT interface (1) , to configure further, and complete the Firepower 1010 initial setup, connect to any one of the LAN interfaces (2), and navigate to (you should get an DHCP address, if you don’t, then you’ve not waited long enough!)
