CCNP Self-Study CCNP Practical Studies: Switching

Book Description

Gain necessary hands-on experience implementing CCNP BCMSN concepts with this practical lab guide

  • Lab configurations include explanations of equipment set-up and execution

  • Valuable reference tool for Catalyst switches, including shortcuts, caveats, and application of the most advanced features

  • Real-world scenarios represent the whole range of CCNP BCMSN 642-811 exam topics

  • CCNP Practical Studies: Switching (CCNP Self-Study) provides CCNP candidates with an in-depth, hands-on experience in configuring Cisco Catalyst switches. This practical guide shows intermediate level networkers how to apply the theoretical knowledge they have gained through CCNP coursework and exam preparation. Configuration labs performed within this book will cover all technologies tested on the BCMSN 642-811 exam, as well as a number of real world scenarios that will test users' overall understanding of multilayer switching. The labs come complete with full explanations, highlighting why the chosen commands and techniques are recommended.

    In addition to applicable labs, this book also provides general information on various switching technologies, as well as tips, tricks, shortcuts, and caveats for deploying Cisco switching gear in production environments. This book also includes exercises (similar to traditional mathematics exercises) that will help readers internalize, practice, and memorize certain concepts and thought processes necessary to successfully deploy a switched network.

    Part of the Practical Studies series from the Cisco Press, CCNP Practical Studies: Switching provides self-study based hands-on experience. As such, it can be used in conjunction with other Cisco Press titles and is an excellent companion to instructor-led training from a Cisco Learning Partner.
