To download images for Cisco ASA, we need a valid Cisco contract other wise we cannot download the software.. In this case, I already have the software which I will upload. I’m using an old Cisco ASA 5505 which is running in my lab network with asa924-k8.bin & asdm-791-151.bin. I will update the ASDM image using a TFTP server as it not getting loaded when connected.
First, we need to set up the TFTP server where the image will be saved. I’m using Tftp64 by Ph. Jounin which can be downloaded here. The current directory is where the image is saved and the server interface is the IP of the machine where the TFTP server is installed. Both TFTP server and ASA are in the same network.
Next, we will SSH into the ASA using putty. Upload the image, and ask ASA to use that image.
ciscoasa# copy tftp flash
Address or name of remote host []? 192.168.10.131
Source filename []? asdm-791-151.bin
Destination filename [asdm-791-151.bin]? enter
asdm image disk0:asdm-791-151.bin
write mem
reload
The process is same If we want to update the ASA images.
