IP Troubleshooting Duration: 3 days

IP Troubleshooting
This course contains the repetition required, and the practical and theoretical exercises needed, to provide the students with the skills for becoming a troubleshooter of generic IP networks.
Firstly, the course contains theory chapters to ensure that the students understand how the data link layer work together with the TCP/IP protocol suite, and the common used features that can cause problems in your network. This includes issues such as auto-sensing, VLANs, subnetting, as well as redundancy logic on both layer 2(spanning tree) and layer 3(routing).
The course will attempt to help students to learn a method for how to perform structured troubleshooting in any generic IP network, including higher layer functions such as TCP/UDP, DHCP and DNS.

This course is suitable for anyone who works with hosts and/or network equipment and that needs to be able to troubleshoot network problems quickly and efficiently, with a good understanding of the bigger picture of IP networks and their functions.

The students need basic knowledge of TCP/IP and generic data communication, but repetition of these subjects will be included in the course.

This is a theoretical training with practical exercises.
