ASDM on Cisco ASA Step by Step

Hello,
This post explains how to enable ASDM on Cisco ASA.

• The first thing you need is to have an interface with an IP address and nameif configured. In my case I have the interface gig0 with the ip address of 10.10.10.1/24 with nameif inside,
• You need to copy the ASDM file into your ASA Flash using the command copy tftp: flash as shown below:

    3. Wait for some seconds until the upload finishes.

    4. Now, to make sure that the ASDM file is uploaded use the command dir

     ciscoasa(config)# dir

Directory of disk0:/

8      drwx  4096         18:26:52 Feb 26 2016  coredumpinfo

13     -rwx  196          18:26:52 Feb 26 2016  upgrade_startup_errors_201602261826.log

11     -rwx  196          18:47:40 Feb 27 2016  upgrade_startup_errors_201602271847.log

268136448 bytes total (250843136 bytes free)

ciscoasa(config)#

         As you can see in the last line, the asdm file is there. 

•      Now enable http function on ASA using the command 

ASA(config)# http server enable

•     You will need to tell the ASA which IP address can access the ASA ASDM. In my case the IP address of my PC is 10.10.10.2/32 including the nameif 

ASA(config)# http 10.10.10.2 255.255.255.255 inside

•   Now to make sure that the https works, go to your web browser and type https://10.10.10.1 You will get a warning, because this is a self signed certificate. Click on proceed. You will get the following screen 

•   Choose the first option to download the ASDM Launcher and then install it. 
•    Run the ASDM Launcher and write the IP address of the ASA and hit enter (notice that the   user name and the password are left blank as we didn't yet configured on the users on the ASA). You will get the warning screen shown below.

•  Just Click on Yes. Wait for a few seconds until the ASDM for ASA management console is loaded as shown below. 

• Finally, save your configurations on ASA using the command write mem

That is all for today! Thanks for your time. See you later.
