Introduction 
It’s hard to imagine a modern data center without applications and Layer 4 to 7 services, which among other 
benefits help address various security, scalability, and high-availability requirements. This document provides both 
an overview and detailed information about how to integrate physical and virtual firewalls with the Cisco
®
 Unified 
Fabric with automation.  
The primary goal of this document is to help readers gain a basic and advanced level of knowledge of how to 
implement some typical firewall deployments in the data center using Cisco Unified Fabric with automation. 
This document is structured to help readers gain knowledge as they progress through the sections, building from 
the basic terms and concepts to advanced topics for planning the deployment. 
Readers will learn about typical firewall deployments and network designs and get a brief introduction to optimized 
networking in the Cisco Unified Fabric. Readers also will learn about how to integrate a firewall into the network 
and the tool set that the Cisco Unified Fabric provides to simplify error-prone and routine tasks. Equipped with this 
knowledge, readers will be presented with several examples that illustrate how to integrate firewalls into Cisco 
Unified Fabric using optimized networking and automation. 
Target Audience 
This document is written for network architects; network design, planning, and implementation teams; and 
application services and maintenance teams. 
Prerequisites 
Readers should be familiar with the fundamental concepts and terms Cisco Unified Fabric with automation before 
proceeding with this document.  
A professional (Cisco CCNP
®
) or higher level of knowledge of routing and switching protocols and network 
deployment best practices is highly recommended. 
Overview of Design and Connectivity in Cisco Unified Fabric Networks with Integrated 
Firewalls 
Typical Firewall Deployments in the Data Center 
The history of networking and service appliances development reveals growth from simple single-server 
applications to clusters of multiple front-end and back-end servers and a shift from simple logic-based rules to 
more advanced URL- and context-based filtering and load balancing. These changes guided the evolution of 
network designs, resulting in many niche and specialized network designs that nevertheless share the same 
fundamental requirements: physical and virtual service appliances must be attached to the network and be 
reachable through static or dynamic routing. Depending on the deployment case, these service appliances may 
also need to attach to one or more Layer 2 domains and connect to a separate management network.
