Cisco ASAv appliance

The Adaptive Security Virtual Appliance is a virtualized network security solution based on the market-leading Cisco ASA 5500-X Series firewalls. It supports both traditional and next-generation software-defined network (SDN) and Cisco Application Centric Infrastructure (ACI) environments to provide policy enforcement and threat inspection across heterogeneous multisite environments.

There is no default password and enable password. A default configuration is present. ASAv goes through a double-boot before becoming active. This is normal and expected.

You need KVM enable on your machine or in the GNS3 VM.

Other versions

If you don't have this images you can try to add a new version follow instructions here.

Only images validated by VIRL team are known to work correctly with GNS3.

Images asav952-204.qcow2 or later are recommend (previous releases may not work). It is very important to use the correct ASA image because only this image (or a later image validated by VIRL) will work with GNS3.

Depending of the image the console of the device could be serial or the graphical output of the VM.

If the image display to the graphical output you need to connect using VNC. Otherwise it’s with the telnet connection.

By default GNS3 appliance use the VNC output because it’s the most common case. If you need to connect via serial you will see this line at the boot:

Lina to use serial port /dev/ttyS0 for console IO

If you see that just edit the configuration of your node to change the console to telnet.

Replace the VNC console by a telnet console

If you want to able to use your terminal application instead of VNC you need to enable the serial console in the appliance.

ciscoasa#conf t
ciscoasa(config)# cd coredumpinfo
ciscoasa(config)# copy coredump.cfg disk0:/use_ttyS0

After that stop the appliance and change the console type from VNC to telnet.

See this thread if you want to create an image with ASAv serial console always enabled:

Once the ASA appliance is imported into GNS3, you can create topologies such as the following:

The cloud is linked to an eth2 interface of the GNS3 VM. In order to have an eth2 interface in the VM in the GNS3 VM settings in VMware (not in GNS3, the parameters of the VM in VMware) add a third network adapter with host only.

We use a generic switch between the cloud and the ASAv vm because a qemu limitation of the current version of GNS3 prevent a direct link between qemu and a cloud.

Our cloud configuration:

The ASA is connected to the switch via is Management 0/0 interface.

After that boot the ASAv it will take a long time with a reboot the first time. Open the console and will see a prompt:


Switch to the configure mode (by default password is empty):

ciscoasa> enable
ciscoasa# configure terminal
***************************** NOTICE *****************************
Help to improve the ASA platform by enabling anonymous reporting,
which allows Cisco to securely receive minimal error and health
information from the device. To learn more about this feature,
please visit:
Would you like to enable anonymous error reporting to help improve
the product? [Y]es, [N]o, [A]sk later: n
In the future, if you would like to enable this feature,
issue the command 'call-home reporting anonymous'.

We can now change the hostname and write the config

ciscoasa(config)# hostname gns3asav
gns3asav(config)# write
Building configuration...

Remember GNS3 will not save this for you. When you save in GNS3 you save the design of topology not the memory of the devices. Like in the real life you need to ask the OS to save before turning it off.

Configure ASDM

In order to manage ASA with asdm we need to setup an ip on the Management 0/0 interface. Because the cloud is a VMware host only adapter we can use DHCP to do that.

ciscoasa(config)# interface Management 0/0
ciscoasa(config-if)# ip address dhcp
ciscoasa(config-if)# no shutdown
ciscoasa(config-if)# nameif mgmt
INFO: Security level for 'mgmt' set to 0 by default.
ciscoasa(config-if)# exit
ciscoasa(config)# show ip
System IP Addresses:
Interface Name IP address Subnet mask Method
Management0/0 mgmt DHCP
Current IP Addresses:
Interface Name IP address Subnet mask Method
Management0/0 mgmt
We can see that our ASA as the IP

Now we need to enable the HTTP server

ciscoasa(config)# http server enable
ciscoasa(config)# http mgmt

Now open and ignore the HTTPS certificate error.

You will see this page

Click on install ASDM launcher. And when you have ASDM on your computer opened it. Enter the IP of the ASA and OK

You will see the ASDM interface

The warning about the licence is normal. The appliance provided by Cisco is dedicated to learning not a production usage where you need to pay.

No console is showing with ASAv


Depending of the image, the serial console could be not activated. If it’s the case you need to connect to via VNC to enable the serial console see this forum post for more details:

Configuration is not saving when running ASAv on Windows

ASAv is not supported by the version of Qemu provided for Windows you need to run it using the GNS3 VM.

If you face any problem setting it up with GNS3 drop me a message and I will get back to you asap.

GNS3 is an open source (GNU GPL) software that simulates complex networks while being as close as possible from the way real networks perform, all of this without having dedicated network hardware such as routers and switches.

GNS3 provides an intuitive graphical user interface to design and configure virtual networks, it runs on traditional PC hardware and may be used on multiple operating systems, including Windows, Linux, and Mac OS X.

In order to provide complete and accurate simulations, GNS3 actually uses the following emulators to run the very same operating systems as in real networks:

Gns3 Cisco Ios Images Download

  • Dynamips, the well known Cisco IOS emulator.
  • VirtualBox, runs desktop and server operating systems as well as Juniper JunOS.
  • QEMU, a generic open source machine emulator, it runs Cisco ASA, PIX and IPS.

GNS3 is an excellent alternative or complementary tool to real labs for network engineers, administrators and people studying for certifications such as Cisco CCNA, CCNP andCCIE as well as Juniper JNCIA, JNCIS and JNCIE.
