Overview

Deploying and Troubleshooting Cisco Wireless LAN Controllers by Mark L. Gress, Lee Johnson

 

This is the only complete, all-in-one guide to deploying, running, and troubleshooting wireless networks with Cisco® Wireless LAN Controllers (WLCs) and Lightweight Access Point Protocol (LWAPP)/Control and Provisioning of Wireless Access Points (CAPWAP). Authored by two of the most experienced Cisco wireless support professionals, the book presents start-to-finish coverage of implementing WLCs in existing wired and wireless network environments, troubleshooting design-related issues, and using LWAPP/CAPWAP solutions to achieve your specific business and technical goals.


One step at a time, you’ll walk through designing, configuring, maintaining, and scaling wireless networks using Cisco Unified Wireless technologies. The authors show how to use LWAPP/CAPWAP to control multiple Wi-Fi wireless access points at once, streamlining network administration and monitoring and maximizing scalability.  Drawing on their extensive problem-resolution experience, the authors also provide expert guidelines for troubleshooting, including an end-to-end problem-solving model available in no other book.


Although not specifically designed to help you pass the CCIE® Wireless written and lab exams, this book does provide you with real-world configuration and troubleshooting examples. Understanding the basic configuration practices, how the products are designed to function, the feature sets, and what to look for while troubleshooting these features will be invaluable to anyone wanting to pass the CCIE Wireless exams.

 

 

  • Efficiently install, configure, and troubleshoot Cisco Wireless LAN Controllers
  • Move autonomous wireless network solutions to LWAPP/CAPWAP
  • Integrate LWAPP/CAPWAP solutions into existing wired networks
  • Understand the next-generation WLC  architecture
  • Use Hybrid REAP and Home AP solutions to centrally configure and control branch/remote access points without deploying controllers in every location
  • Use Mobility Groups to provide system-wide mobility easily and cost-effectively
  • Use Cisco WLC troubleshooting tools, and resolve client-related problems
  • Maximize quality in wireless voice applications
  • Build efficient wireless mesh networks
  • Use RRM to manage RF in real-time, optimizing efficiency and performance
  • Reference the comprehensive WLC and AP debugging guide

 

Part of the CCIE Professional Development Series, this is the first book to offer authoritative training for the new CCIE Wireless Exam. It will also serve as excellent preparation for Cisco’s new CCNP® Wireless exam.

The first chapter is the most valuable. It offers broad tips for a top down debugging approach to a wireless network problem. Also, it is largely independent of specific hardware elements. You can apply the guidelines even if you have non-Cisco items in the network. Of its advice, two very good tips stand out. The first is simply to have an extensive and complete network diagram. Do this when everything is [presumably] working. Don't wait till things go wrong before amassing such a diagram. The second tip is to imagine you are offsite and are talking on the phone to an onsite sysadmin. And no visuals on your phone. It's strictly audio. This gedanken forces you to focus on what might be the key features of the problem. The rest of the book then delves into specific abilities of Cisco boxes. Often there might be diagnostic text output that you can get. Cisco has been careful about enabling its machines to provide copious diagnostic dumps. The mass of detail is needed because of the many possible failure symptoms. But this also means that part of the skill you should cultivate is an intuition about what to look for in a potential surfeit of a data dump. One impression from the book is that wireless problems can be harder than those in an all-wired network. For the latter, at least in principle, you can trace the wires and test each link. But wireless transceivers can overlap in broadcast range. While evesdropping does not require physical access to your equipment by an adversary.
