CCNP Practical Studies: Troubleshooting

Book Description

Hands-on practice for the CCNP Troubleshooting exam with TCP/IP, LAN, and WAN trouble tickets based on Cisco Internetwork Troubleshooting (CIT) topics

With this book, you can:

  • Set up and follow along with real-world lab scenarios aligned to each exam topic, with or without the actual equipment

  • Establish a baseline and document your physical and logical network

  • Identify troubleshooting targets using ping, trace, show, clear, debug, and other troubleshooting tools and utilities

  • Diagnose and troubleshoot actual problems by following along with author-provided Catalyst(r) OS and Cisco IOS(r) Software command input, output, and logging

  • Use instructor-developed problem-isolation methods to resolve Trouble Tickets

  • "Sniff" the wire to spot network issues

  • Analyze local and remote access problems in Ethernet networks, including issues with cabling, speed and duplex, utilization and collisions, bandwidth, CSMA/CD, one-way link, auto negotiation, addressing, encapsulation, and more

  • Apply a layered troubleshooting methodology to real-life routing and switching environments

  • Designed for aspiring CCNP and CCIE(r) professionals, this indispensable lab guide builds on Cisco(r) Internetwork Troubleshooting (CIT) topics that prepare you for the CCNP Troubleshooting exam. Full of practical exercises that get you ready for challenges on the job, CCNP Practical Studies: Troubleshooting gives you an edge over the competition through real-world application of LAN and WAN topics.

    CCNP Practical Studies: Troubleshooting provides you with practical information on all the important concepts central to the troubleshooting portion of the CCNP certification, including protocol characteristics and tools and supporting IP, IPX, Ethernet, switches, VLANs, and WANs. Each chapter contains an overview of standards and protocols, troubleshooting tools, and basic methods and documentation techniques, as well as hands-on scenarios. Although having access to equipment is the ideal way to profit from this book, relevant information delivered through figures, configuration examples, and detailed text ensures everyone can benefit from the information presented. Protocol analyzer traces emphasize important concepts and trouble areas. Chapters end with real-world Trouble Tickets designed to give you additional practical experience. The final chapter, "Trouble Tickets: The Sum of All Fears," offers comprehensive troubleshooting scenarios in which you must identify, diagnose, and solve complex issues using the methods you have learned.

    Whether you are seeking practical knowledge to enhance your preparation for the CCNP Troubleshooting exam or you are a newly minted CCNP in need of hands-on experience to hone your on-the-job skills, CCNP Practical Studies: Troubleshooting has what you need to take your troubleshooting skills to the next level.
