ASA 5545-X and ASA 5555-X

2. License Requirements

ASA Licenses

The ASA 5506-X includes the Base or Security Plus license, depending on the version you ordered. It also comes pre-installed with

the Strong Encryption (3DES/AES) license if you qualify for its use. You can optionally purchase an AnyConnect Plus or Apex

license.

If you need to manually request the Strong Encryption license (which is free), see http://www.cisco.com/go/license.

If you want to upgrade from the Base license to the Security Plus license, or purchase an AnyConnect license, see

http://www.cisco.com/go/ccw. See also the Cisco AnyConnect Ordering Guide and the AnyConnect Licensing Frequently Asked

Questions (FAQ). You will then receive an email with a Product Authorization Key (PAK) so you can obtain the license activation

key. For the AnyConnect licenses, you receive a multi-use PAK that you can apply to multiple ASAs that use the same pool of user

sessions.

Note: The serial number used for licensing is different from the chassis serial number printed on the outside of your hardware. The

chassis serial number is used for technical support, but not for licensing. To view the licensing serial number, enter theshow version

| grep Serial command or see the ASDM Configuration > Device Management > Licensing Activation Key page.

ASA FirePOWER Licenses

The ASA FirePOWER module uses a separate licensing mechanism from the ASA. No licenses are pre-installed, but the box

includes a PAK on a printout that lets you obtain a license activation key for the following licenses:

Control and Protection—Control is also known as “Application Visibility and Control (AVC)” or “Apps”. Protection is also

known as “IPS”. In addition to the activation key for these licenses, you also need “right-to-use” subscriptions for automated

updates for these features.

The Control (AVC) updates are included with a Cisco support contract.

3. Power On the ASA

Cisco ASA 5512-X, ASA 5515-X, ASA 5525-X, ASA 5545-X, and ASA 5555-X Quick Start Guide 3

The Protection (IPS) updates require you to purchase the IPS subscription from http://www.cisco.com/go/ccw. This

subscription includes entitlement to Rule, Engine, Vulnerability, and Geolocation updates. Note: This right-to-use subscription

does not generate or require a PAK/license activation key for the ASA FirePOWER module; it just provides the right to use the

updates.

Other licenses that you can purchase include the following:

Advanced Malware Protection (AMP)

URL Filtering

These licenses do generate a PAK/license activation key for the ASA FirePOWER module. See the Cisco Firepower System Feature

Licenses for more information.

To install the Control and Protection licenses and other optional licenses, see Install the Licenses, page 12.

3. Power On the ASA

1. Attach the power cable to the ASA and connect it to an electrical outlet.

The power turns on automatically when you plug in the power cable; do not press the power button on the front panel. (For

older models, the power does not turn on automatically; check the hardware installation guide for more information).

2. Check the Power LED on the front of the ASA; if it is solid green, the device is powered on.

3. Check the Status LED on the front of the ASA; after it is solid green, the system has passed power-on diagnostics.

4. Modify the Initial Configuration for the ASA FirePOWER

Module (Optional)

The ASA ships with a default configuration that enables Adaptive Security Device Manager (ASDM) connectivity to the

Management 0/0 interface. When you use a software module such as the ASA FirePOWER module, we recommend that you do

not use the default configuration, which can preclude the ASA FirePOWER module from reaching the Internet for updates. This

section describes how to apply a new configuration so the ASA FirePOWER can access the Internet. This configuration also enables

a basic usable configuration for an inside and outside network.

ASA 9.7 and Later

The following figure shows the recommended network deployment for the ASA 5500-X with the ASA FirePOWER module. This

deployment includes an inside bridge group that includes all but the outside interface so you can use these interfaces as an alternative

to an external switch.

4. Modify the Initial Configuration for the ASA FirePOWER Module (Optional)

Cisco ASA 5512-X, ASA 5515-X, ASA 5525-X, ASA 5545-X, and ASA 5555-X Quick Start Guide 4

Note: The ASA 5525-X, 5545-X, and 5555-X include interfaces GigabitEthernet 0/0 through GigabitEthernet 0/7.

This procedure lets you connect to the ASA console port and paste in a new configuration that configures the following behavior:

outside GigabitEthernet 0/0, IP address from DHCP

inside bridge group with GigabitEthernet 0/1 through 0/5 (or through 0/7 for the ASA 5525-X, 5545-X, and 5555-X) member

interfaces, 192.168.1.1

inside --> outside traffic flow

inside --> inside traffic flow for member interfaces

DHCP for clients on inside

Management 0/0 belongs to the ASA FirePOWER module. The interface is Up, but otherwise unconfigured on the ASA. The

ASA FirePOWER module can then use this interface to access the ASA inside network and use the inside interface as the

gateway to the Internet.

Note: Do not configure an IP address for this interface in the ASA configuration. Only configure an IP address in the

FirePOWER configuration. You should consider this interface as completely separate from the ASA in terms of routing.

ASDM access on the inside interface

NAT: Interface PAT for all traffic from inside and management to outside.

Note: If you want to deploy a separate router on the inside network, then you can route between management and inside. In this

case, you can manage both the ASA and ASA FirePOWER module on Management 0/0 with the appropriate configuration changes.

a. Cable Management 0/0 (for the ASA FirePOWER module) directly to one of: GigabitEthernet 0/1 through GigabitEthernet

0/5 (through 0/7 for the ASA 5525-X, 5545-X, and 5555-X).

Note: You can connect inside and management on the same network because the management interface acts like a separate

device that belongs only to the ASA FirePOWER module.

b. Cable your computer to one of: GigabitEthernet 0/1 through GigabitEthernet 0/5 (through 0/7 for the ASA 5525-X, 5545-X,

and 5555-X).

c. Cable GigabitEthernet 0/0 (outside) to your WAN device, for example, your cable modem.

Note: If the cable modem supplies an outside IP address that is on 192.168.1.0/24 or 192.168.10.0/24, then you must change

the ASA configuration to use a different IP address. Interface IP addresses, HTTPS (ASDM) access, and DHCP server settings

can all be changed using the Startup Wizard. If you change the IP address to which you are connected to ASDM, you will be

disconnected when you finish the wizard. You must reconnect to the new IP address.

Note: If you have an inside router instead of a switch, you can skip this section and instead configure the ASA to route between

management and an inside network. In this case, configure the ASA and the ASA FirePOWER Management 0/0 IP addresses to be

on the same network. Be sure to configure appropriate routes on the ASA and on the ASA FirePOWER so the management network

can reach the inside network, and vice versa.

This procedure lets you connect to the ASA console port and paste in a new configuration that configures the following behavior:

inside --> outside traffic flow

outside IP address from DHCP

DHCP for clients on inside

Management 0/0 belongs to the ASA FirePOWER module. The interface is Up, but otherwise unconfigured on the ASA. The

ASA FirePOWER can then use this interface to access the ASA inside network and use the inside interface as the gateway to

the Internet.

Note: Do not configure an IP address for this interface in the ASA configuration. Only configure an IP address in the module

configuration. You should consider this interface as completely separate from the ASA in terms of routing.

ASDM access on the inside interface

To achieve the above configuration, perform the following steps.

Procedure

1. Connect your computer to the ASA console port with the supplied console cable. You might need to use a third party

serial-to-USB cable to make the connection.

2. Launch a terminal emulator and connect to the ASA.

3. Press the Enter key to see the following prompt:

Note: You can connect inside and management on the same network because the management interface acts like a separate

device that belongs only to the ASA FirePOWER module.

b. Connect the outside GigabitEthernet 0/0 interface to your upstream router or WAN device.

Note: If the cable modem supplies an outside IP address that is on 192.168.1.0/24 or 192.168.10.0/24, then you must change

the ASA configuration to use a different IP address. Interface IP addresses, HTTPS (ASDM) access, and DHCP server settings

5. Launch ASDM

See the ASDM release notes on Cisco.com for the requirements to run ASDM.

This procedure assumes you want to use ASDM to manage the ASA FirePOWER Module. If you want to use the Firepower

Management Center, then you need to connect to the module CLI and run the setup script; see the ASA FirePOWER quick start

guide.

Procedure

1. On the computer connected to the ASA, launch a web browser.

2. In the Address field, enter the following URL: https://192.168.1.1/admin. The Cisco ASDM web page appears.

3. Click one of the available options: Install ASDM Launcher, Run ASDM, or Run Startup Wizard.

4. Follow the onscreen instructions to launch ASDM according to the option you chose. The Cisco ASDM-IDM Launcher

appears.

If you click Install ASDM Launcher, in some cases you need to install an identity certificate for the ASA and a separate

certificate for the ASA FirePOWER module according to Install an Identity Certificate for ASDM.

5. Leave the username and password fields empty, and click OK. The main ASDM window appears.

6. If you are prompted to provide the IP address of the installed ASA FirePOWER module, cancel out of the dialog box. You must

first set the module IP address to the correct IP address using the Startup Wizard.

ASDM can change the ASA FirePOWER module IP address settings over the ASA backplane; but for ASDM to then manage

the module, ASDM must be able to reach the module (and its new IP address) on the Management 0/0 interface over the

network. The recommended deployment allows this access because the module IP address is on the inside network. If ASDM

cannot reach the module on the network after you set the IP address, then you will see an error.

7. Choose Wizards > Startup Wizard.

8. Configure additional ASA settings as desired, or skip screens until you reach the ASA FirePOWER Basic Configuration

screen.
