Introduction

There are two fundamental components of modern networks todayrouting and switching. The Cisco Certified Network Professional (CCNP) certification is a popular networking certification that is the next step in career certification following the Cisco Certified Network Associate (CCNA) certification. Cisco represents qualified individuals at three tiers, CCNP-qualified people represent the middle tier, while CCNA represents the lower tier, and CCIE the highest tier. Demand for CCNPs is high, especially for organizations that need people to implement and support Cisco-based networks. One of the requirements of obtaining CCNP is to pass the CCNP Switching exam, which tests your knowledge of switching concepts, protocols, and the configuration of Cisco Catalyst switches. This book is designed to provide you with a greater understanding of how to configure (and support) Cisco Catalyst switches.
