TCP/IP Network Analysis and Troubleshooting

Overview:

The TCP/IP Network Analysis and Troubleshooting course focuses on the protocols and issues facing network managers today. This five-day course offers students an opportunity to review the operational aspects of the TCP/IP suite including protocols at the OSI Network Layer (IP, ARP, ICMP), OSI Transport Layer (UPD, TCP), and at the Application Layer (FTP, DNS, DHCP, HTTP). In addition, this course will focus on issues related to security and addressing at each layer of the protocol stack. This course will prepare students to identify and solve very complex problems that commonly affect medium and large enterprise-wide networks. Key concepts are reinforced through hands-on exercises and interactive “Try it now!” labs.

Description:

Participants learn to:
• Effectively manage and troubleshoot TCP/IP environments
• Recognize how IP addressing enables the delivery of packets to the intended destination
• Overcome the limitations of IP v4 addressing
• Identify routing issues
• Analyze the operations of the transport layer and look for the clues that lead to solutions
• Look at the significant bits and bytes in headers to assist troubleshooting
• Use Sniffer information to diagnose problems in applications that support internal and e-commerce applications
• Analyze the operations of the session, presentation, and application layers 
• Determine application response time
• Draw conclusions regarding problems revealed in symptoms and diagnoses

Required prerequisites:
• Network Analysis and Troubleshooting (TRN-101-TCL)
• Students must have a working knowledge of LAN technologies and topologies, the OSI reference model, and the function of network devices

Suggested next courses:
• Advanced Troubleshooting with Sniffer InfiniStream (TRN-271-TCL)
• Microsoft Windows Network Analysis and Troubleshooting (TRN-323-TCL)
