Overview

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.
