How to set up ASDM on a Cisco ASA
Posted on 25 October 2017 by Beaming SupportCisco ASA devices allow for configuration to be made via a Java application. In order to set the ASA up to use the Java application, you will need to complete some basic configuration from the CLI of the ASA. Please make sure that Java is installed on your laptop prior to completing the below.
This is written under the assumption that the ASA has been factory reset.
Connect your console cable to the ASA and connect to it via Putty. Once the ASA has finished loading, go into enable mode. The default password is cisco with no username.
We will set up the management interface for connecting our laptop to ASDM.
Ciscoasa# conf t
Ciscoasa#(config) int management0/0
Ciscoasa#(config-if)ip address 192.168.1.1 255.255.255.0
Ciscoasa#(config-if) nameifManageASDM
Ciscoasa#(config-if)no shut
Ciscoasa#(config-if) Security-level 100
This sets the management interface IP address and names it for later use. Now we can set up the web server that we will connect to.
Ciscoasa#(config) http server enable
Ciscoasa#(config) http 192.168.1.0 255.255.255.0 ManageASDM(matches management int name)
Now we need to set an “enable username” for connecting to the ASDM interface.
Ciscoasa#(config)enable password firewall level 15
Next, connect the Ethernet port of your laptop to the management port of the ASA and set a static IP on the laptop, in the 192.168.1.0/24 range (but not 192.168.1.1).
On your laptop, open a browser and go to https://192.168.1.1/admin to get to the Cisco ASDM page. Accept the certificate error and continue to the webpage.
The last step is to click Install ASDM Launcher and Run ASDM from the webpage. The installer will then run through the process of installing. You’ll then need to go to the install location and create a shortcut to your desktop.
Open the shortcut and fill in the IP address (192.168.1.1), leave the username blank and put in the password firewall. The ASDM will then connect to the ASA and load the java interface.
You can now configure the ASA as per your requirements.
