About this course

Course code TPTCPIP
Duration 5 Days

An intensive hands on IP foundation. The course focuses on all parts of TCP/IP including layers 4 to 7 on end stations as well as layer 3 on routers. The TCP/IP protocols are also studied to enable delegates to be able to troubleshoot TCP/IP using LAN Analysers. Hands on sessions are used to reinforce the theory rather than teach specific manufacturer equipment.

Delegates will learn how to

By the end of the course delegates will be able to: Use ping, traceroute and other tools to diagnose faults on a network. Configure IP on PCs and routers. Plan IP addresses and subnets Analyse IP and TCP packets using an analyser. Troubleshoot TCP/IP.
