Description

Ethernet is the network access layer of TCP/IP. This course describes different Ethernet copper and fiber options. Ethernet media options are presented with a description of the most common connectors and cable types.
The Ethernet frame structure is introduced, and important fields are explained. MAC addresses and their function are described, while switch frame processing operations and duplex options are explained. The course also covers collision domains and provides configuration examples for duplex settings.
Most issues that affect a switched network are encountered during the original implementation. Theoretically, once it is installed, a network continues to operate without problems. However, that’s only true in theory. Cabling gets damaged, configurations change, and new devices are connected to the switch that require switch configuration changes. This course concludes by describing the most common media and port issues and how to troubleshoot them.
