Course Format: Classroom | E-learning | Virtual Class | Online | On-site | Blended | Self-paced

Course Description:

'' Learn to prevent, detect, troubleshoot, and correct TCP/IP network problems, before your users know there’s a problem. Use field metering tools and protocol analysers to troubleshoot a live TCP/IP network. Identify and correct protocol errors, DNS route problems, application faults, and slow response.

Learn How To

Troubleshoot and repair problems on a TCP/IP enterprise network
Monitor networks using Protocol Analysers
Deploy effective methods of baselining and Trend Analysis

What You’ll Learn
Course Outline
1. Effective Troubleshooting
2. Technology Overview
3. Knowing Your Network
4. Troubleshooting Tools
5. Protocol Analyser Basics
6. Troubleshooting Methodology
7. Layer-by-Layer Issues

Course Labs

Demo Lab 1: In this instructor-led demo, learn monitoring facilities of the protocol analyser used in the course.
Lab 2: Collect and analyse data to establish a baseline for the classroom network.
Lab 3: Examine the available options of the ping command and exercise the 7-step ping procedure discussed in class.
Lab 4: Use traceroute to verify that the routers are working properly. Compare those results to those generated by the IP record route option.
Lab 5: Gain experience using nslookup to query DNS servers to diagnose and troubleshoot errors.
Lab 6: Use netstat to get information on the status of networking devices, routing tables and TCP/UDP connections.
Lab 7: Use ping to identify the effect packet size and path have on round-trip times. You also identify multiple ways to answer questions about identified network characteristics.
Lab 8: Practice several methods of setting up and using filters on the protocol analyser.
Lab 9: Examine, decode, and interpret multiple ICMP error messages. Identify a wide variety of scenarios that could produce such messages.
Lab 10: Using a protocol analyser, inspect and discuss the characteristics of various TCP/IP applications including Telnet, FTP and the Web. Learn where to look to identify application faults.
Lab 11: Using the tools and techniques refined in previous labs, find the source of a communication failure as soon as possible and fix it.
Lab 12: A user has recently moved to a new cubicle and can’t use any of the applications he has used in the past. In this lab, identify dozens of potential causes for communication problems.
Lab 13: Users are able to communicate to some hosts on the network, but not others. Determine who can talk to whom, isolate the source of the problem, and fix it.
Lab 14: Classroom teams work together to discover how Microsoft’s TCP/IP implementation prevents problems by detecting and reporting duplicate IP addresses on the network.
Lab 15: Using nslookup and other tools, verify that DNS is working properly.
Lab 16: A disgruntled employee has gotten in
