About the Guide

Audience

This design guide is intended for Cisco systems and customer engineers responsible for designing campus networks with Virtual Switching Systems 1440.

Document Objectives

This document provides design guidance for implementing the Cisco Catalyst 6500 Series Virtual Switching System (VSS) 1440 within the hierarchical campus architecture. Chapter 1, "Virtual Switching Systems Design Introduction" covers traditional design approaches and architectural scope of campus. Chapter 2, "Virtual Switching System 1440 Architecture" introduces the critical components of VSS and provides best-practice design options and recommendation specific in configuring VSS in campus. Chapter 3, "VSS-Enabled Campus Design" discusses the application of VSS in campus and illustrates the traffic flow and campus-specific best practice design recommendation. Chapter 4, "Convergence" illustrates the validated design environment. It includes the convergence characteristics of end-to-end campus enabled with VSS.


Note Throughout the remainder of this guide, the Cisco Catalyst 6500 Series VSS will be referred to as the VSS.


This design guide references and uses accumulated best-practice knowledge documented and available in the documents listed in Appendix B, "References." However, during the development of this design guide, many design choices have been made to replace or update specific options recommended for VSS-specific deployments. This design guide makes explicit references to and/or reaffirms Cisco best practices.

Document Organization

This design guide contains the following chapters and appendices:
