Workshop

  1. Protocol Analyzer Setup, Use, and In-Depth Analysis

    Using a WLAN protocol analyzer is a fundamental piece of network troubleshooting. In this course, protocol analysis is the foundation for hands-on learning, as students will use these tools to gain familiarity with and exposure to analyzer features and use, frame formats, and protocol operation. This lab set (10 labs) is focused on gaining familiarity with analysis tools, using them to capture traffic, and interpreting the frame traces:

    • Basic installation and familiarity with capabilities, configuration, and data display
    • Opening, collecting, saving, and modifying capture files
    • Exploring common features like device naming and prioritization, filtering traffic, and using coloring rules as analysis aides
    • Configuration of the tool to perform live captures based on a set of desired collection criteria
    • Identifying significant network behaviors, metrics, and statistics used to identify and isolate network problems
    • Using expert features of the analyzer, such as conversation analysis
    • Remote packet capture with an AP
  2. Understanding Frame Components

    This lab set (9 labs) is focused on using analysis tools to capture and visualize the 802.11 frame types, uses, and formats first hand. Familiarity with the frame structure and contents is essential in real-world troubleshooting efforts, and this lab is designed to provide that familiarity so that both normal behavior and problematic behavior can be identified. Areas of focus include:

    • Understanding the MAC header
    • Comparing the three major frame types and their subtypes
    • Analyzing frame formats of individual frame types
    • Analyzing 802.11n frame components
    • Identifying what additional information is reported by protocol analyzers
    • Understanding what information is not visible in protocol analyzers
  3. Frame Exchanges

    In addition to understanding the frame types and formats in WLANs, it is essential to know how and when each frame is used in interactive communication. Understanding frame exchange rules and behaviors is critical to identifying expected and unexpected. It is also necessary to understand what is normal so that aberrations can be properly troubleshot. This lab is focused on observing and explaining WLAN behavior using a protocol analyzer. The following will be covered in this lab exercise:

    • Connectivity exchanges and sequences
    • Legacy and modern security exchanges
    • ERP and HT protection mechanisms
    • Power save behavior
    • Acknowledgments, block acknowledgments, and supporting action frames
    • Dynamic rate switching
    • Band steering
    • And more
  4. Troubleshooting Common Problems

    This lab exposes students to hands-on troubleshooting skills by setting up common problems in WLANs and allowing students to attempt to solve them.

    • Troubleshooting connectivity exchanges
    • Troubleshooting 802.1X and EAP exchanges
    • Troubleshooting roaming
  5. Spectrum Analyzer Setup, Use, and In-Depth Analysis

    This lab section is focused on gaining confidence and familiarity with spectrum analyzers. Specifically, it will explore the plots and charts used to display spectrum data and how to interpret this data to define a transmitter’s impact on the network. The following steps will be covered in this lab exercise.

    • Installing the analyzer and becoming familiar with display and navigation
    • Understanding the “RF perspective” provided by each plot and chart
    • Using built-in features like markers and traces as well as automated device identification
    • Characterizing the behaviors of an interference source
    • Assessing the impact of an interference source
    • Determining the impact of transmitter proximity on interference and spectrum displays
    • Identifying signatures of common transmitters
    • Remote spectrum analysis with an AP
