Category: Network Access
Length: 4 days

Description:
A 4-day, intense hands-on course involving network testing and troubleshooting strategies with network test equipment and protocol analyzers for LAN, WAN, and carrrier environments.

Prerequisites:
Completion of Computer Network Operations course (ISS220) or equivalent experience with LAN/WAN maintenance

Course Outline:
Network Analyzer Fundamentals
Describe the basic operations of network analyzers

• Protocol Analyzer Basic Operations
• Protocol Analyzer Usage: Testing, Emulating, Data Gathering, Trouble Filtering, Trapping, Configuring, Traffic Generation, and Metering
• Protocol Analyzer Types and Examples: Carrier Testers/Analyzers, Interface and Cable Testers, and WAN/LAN Analyzers

Basic Approach to Analyzer Operations/Usage
Perform essential operations for attaching analyzers to your network

• Benchmarking the Network: Expected Protocol Behavior: Signaling/Transmission, Addressing/Routing, Presentation, Confirmation, Flow Control, Error Detection/Correction, and Message Integrity
• Protocol Types and Data Streams Review: ASYNC, SYNC, Packet/Circuit Switched, LAN/WAN, and Internetworking
• Troubleshooting Methods/Symptom Analysis: Symptom Recognition, Data Gathering/Testing, Trouble Identification/Trouble Resolution

Data Gathering and Symptom Recognition
Perform data gathering using the test set and associate typical network symptoms with likely causes

• Generating Traffic/Patterns for Testing
• Data Gathering/Testing Implementation: Cable/Interface Tester, T-Carrier Tester, and LAN/WAN Analyzer
• Observing Network Symptoms and Determining Likely Causes

Trouble Identification and Resolution
Resolve network troubles in a thorough and timely manner

• Comparing actual data with expected protocol operations/performance
• Trouble detection and isolation
• Confirming the trouble: analyzer simulation/emulation
• Trouble resolution: re-configure, replacement, repair, and performance optimization
