This is a very quick post to explain how to update your ASA firewall. nothing big as it’s very easy but since I had to put together the info to get that documented for my colleagues, I thought I could post it here too.

1. Copy the file on a FTP (CI33024)
2. Logon to the firewall
3. Issue the following commands:
en
copy ftp://[ipaddress]/[filename] disk0:[filename]

You‘ll have to confirm the parameters and then you should see something like that:
Accessing tftp://172.16.31.1/asa722-k8.bin…!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Writing file disk0:/asa722-k8.bin…
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
8312832 bytes copied in 163.350 secs (50998 bytes/sec)

4. Chech that the file has been copied correctly

You should see something similar:
-#- –length– —–date/time—— path

7 5623108 Feb 12 2010 00:23:48 asdm-631.bin
10 5539756 Feb 12 2007 00:14:18 asdm-521.bin
11 8294400 Dec 07 2006 05:47:20 asa721-24-k8.bin
12 6002680 Dec 21 2006 03:58:30 asdm-52034.bin
13 8312832 Feb 12 2010 22:46:30 asa831-k8.bin

23949312 bytes available (38932480 bytes used)

5. Go to the configuration mode (conf t) and type the following command:
boot system disk0:/asa831-k8.bin

This will replace the path of the image the firewall boot on.
If you update de asdm, the command is slightly different.

asdm image disk0:/asdm-631.bin

6. Save the config:
write memory

7. Reload the config:
reload
