Practical Troubleshooting of TCP/IP Networks

Training Overview:

This course is a hands-on workshop, where you will spend over 70% of the course time in setting up and troubleshooting TCP/IP-based networks. Commencing with a simple introduction to the hardware level of Ethernet, you will quickly move onto coverage of the Internet (IP) layer. The Host-to-Host (TCP) layer also be covered in considerable practical detail. The Application layer of the TCP/IP protocol suite will be covered by a detailed examination of protocols such as BOOTP, DHCP and SNMP. The simple but vital TCP/IP utilities such as Ping, Arp and Tracert will then be tested out on the network. Finally, you will construct a Virtual LAN and Virtual Private Network, and configure a simple firewall. One of the best ways to learn and retain your knowledge is with handson sessions where you will gain a broad range of skills that every competent network engineer needs in his skills toolbox.

Training Outline:

  1. Networking Basics (Overview):
  • OSI model
  • Ethernet
  • TCP/IP protocol suite
  • Internet layer (OSI layer 3) protocols: IP, ARP, ICMP
  • Host-Host Layer (OSI Layer 4) protocols: TCP, UDP
  • Application Layer (OSI Layer 5/6/7) protocols: FTP, HTTP, Telnet
  • Network components
  1. Tools:
  • DOS utilities
  • Windows utilities (IP scanners, port scanners, route tracers)
  • Protocol analysers
  1. Network Construction:
  • Constructing a simulated Wide Area Network simulation with hubs, switchesand routers
  • Setting up Cisco routers
  • Setting up managed switch
  • Setting up DHCP and BOOTP servers
  • Configuring IP
  1. Basic System Checks
  • Host configuration (ipconfig, wntipcfg)
  • Router configuration
  • Switch configuration
  • Connectivity (ping, arp, tracert)
  • Name resolution (Hosts file, NetBIOS name resolution)
  1. Troubleshooting The Medium
  • Fiber connectivity
