description
This workshop is a practical workshop devoted to two days of hands-on faultfinding and troubleshooting. After an initial familiarisation session on industrial Ethernet and TCP/IP the two days is devoted to practical hands-on exercises. The workshop has been structured to cover key issues in troubleshooting TCP/IP and Ethernet in detail, while going through the practical implementation of TCP/IP in office and industrial networks and the practical use of the Internet and Intranets. Troubleshooting and maintenance of TCP/IP networks and communication systems in an office and industrial environment are also covered. 15 practical mini-sessions expose you to typical problems that could occur with industrial Ethernet and TCP/IP networks and shows you how to fix them. Most of each day comprises practical sessions with a modicum of discussion to explain the key points. There will be a minimum of two people to a PC so that the practical component will be emphasised. At the end of this workshop you will walk away with a solid knowledge on troubleshooting industrial Ethernet and TCP/IP networks.

Local Area Network
is a communications system is constrained within an organisation is privately owned covers about 2 to 3 km maximum will include:-
workstations, servers & peripherals a shared access medium

Wide Area Network WAN
Elements are separated by distances that require telecommunications links Publicly or privately owned Shared lines - packet & circuit switched Leased lines - dedicated connection Distance can be global - 1000s+ km Slow to medium speed (now) cf LANs High error rates (1 in 1 Mbits)
Open Systems and Communications
Specifications open to all ISO defined OSI Model (1978) 7 Layers Not a Protocol but an overall framework
Protocols can be developed for layers independently

Troubleshooting Methodology
Most problems occur in lowest layers Systematically check these first Many problems with cables and Physical layer
broken wires, connector issues and noise Data Link Layer
Ethernet interfaces, switches Network layer
IP configuration, routers and firewalls
