Other than the 4 network ports, you’ll also see slots marked as mgmt, usb, usb, console, aux, flash card. In our example, we’ll be using port 0, 1, and 3 as explained above. On the Cisco ASA 5520 model, it has 4 ports on the back, marked as 0, 1, 2 and 3. fail3 indicates that this is connected to the port 3 on the device. fail3 – Assign an internal ip-address to this interface that will be used between the primary and secondary devices during failover.
int1 indicates that this is connected to the port 1 on the device. int1 – Assign your internal ip-address to this interface.ext0 indicates that this is connected to the port 0 on the device. ext0 – Assign your external ip-address to this interface.The following diagram explains on a high-level the ip-address that are assigned to the primary and secondary cisco ASA devices in this example. This way, if the primary ASA fails, the secondary becomes active automatically without any downtime. On a production environment, it is highly recommended to implement two Cisco ASA firewall (or VPN) in high available mode.
