Chapter 4: Firepower Management Center (FMC) Hardware

This chapter discusses and compares various hardware platforms for the FMC. It illustrates the complete reimaging process (also known as System Restore) and describes the best practices for doing it. You can also learn many different command-line tools to determine any issues with FMC hardware.

Chapter 5: Firepower System Virtual on VMware

This chapter describes various aspects of the Firepower virtual appliance, such as how to deploy a virtual appliance, how to tune the resources for optimal performance, and how to investigate issues with a new deployment.

Chapter 6: The Firepower Management Network

This chapter describes the best practices for designing and configuring a management network for the Firepower System. It also discusses the tools you can use to verify any communication issues between the management interfaces of the FMC and FTD. Before you begin the registration process, which is described in Chapter 7, you must ensure that the FMC and FTD are successfully connected through your network.

Chapter 7: Firepower Licensing and Registration

This chapter discusses licensing and registration—two important initial tasks in a Firepower system deployment. It describes the capabilities of different Firepower licenses and the steps involved in registering the FMC with a Smart License Server. It also demonstrates the registration process and the tools to investigate any communication issues.

Chapter 8: Firepower Deployment in Routed Mode

This chapter explains Routed Mode, which is a widely deployed firewall mode. It describes the steps involved in configuring the routed interfaces with static IP addresses as well as dynamic IP addresses. In addition, this chapter discusses various command-line tools you can use to determine any potential interface-related issues.

Chapter 9: Firepower Deployment in Transparent Mode

This chapter discusses another mode, Transparent Mode, including how to configure the physical and virtual interfaces, and how to use various command-line tools to investigate any potential configuration issues.

Chapter 10: Capturing Traffic for Advanced Analysis

This chapter describes the processes involved in capturing live traffic on an FTD device by using the system provided capturing tool. To demonstrate the benefit of the tool, this chapter shows how to use various tcpdump options and BPF syntaxes to filter and manage packet capture.

Chapter 11: Blocking Traffic Using Inline Interface Mode

This chapter demonstrates how to configure an FTD device in Inline Mode, how to enable fault tolerance features on an inline set, and how to trace a packet in order to analyze the root cause of a drop. This chapter also describes various command-line tools that you can use to verify the status of an interface, an inline pair, and an inline set.

Chapter 12: Inspecting Traffic Without Blocking It

This chapter explains the configuration and operation of various detection-only modes of an FTD device, such as Passive Mode, Inline Tap Mode, and Inline Mode with the Drop When Inline option disabled. It also provides various command-line tools that you can use to determine the status of interfaces and traffic.

Chapter 13: Handling Encapsulated Traffic

This chapter shows you how to analyze and block traffic that is encapsulated with the GRE protocol. This chapter also demonstrates the steps to bypass an inspection when the traffic is transferred over a tunnel. Besides showing configurations, this chapter also shows various tools to analyze an action applied by the Prefilter and Access Control policy of an FTD device.

Chapter 14: Bypassing Inspection and Trusting Traffic

This chapter discusses the techniques to bypass an inspection. It provides the steps to configure different methods.
