TR02 - TCP/IP Network Analysis using the Observer® Analyzer
This 2 day course covers issues and protocols in the TCP/IP environment. Students learn to troubleshoot common problems at all layers of the TCP/IP stack. Students also learn to examine, and analyze components using a network analyzer.
Students learn to:
• Effectively manage and troubleshoot TCP/IP environments
• Analyze the operations of the TCP layer and look for clues that lead to solutions
• Utilize knowledge of the functions of important upper-layer protocols to analyze trace files for erroneous conditions and understand how to correct them
• Draw conclusions regarding problems revealed in network analyzer traces
Prerequisite: TR01
2 Days, $1295
Objective:
Manage and troubleshoot TCP/IP environments. Know how IP addressing provides for the delivery of packets to the intended destination address. Know how to use the significant bits and bytes in the protocol headers to assist in troubleshooting. Analyze the operations of the TCP layer and look for solutions. Understand the functions of important upper-layer protocols to analyze trace files for erroneous conditions and solve them. Develop conclusions based on problems identified in the Expert Application.
