Ethernet LANs and Switching

In this OnDemand course, ICT professionals will learn about the history of Ethernet, NIC and MAC addresses, and unicast, multicast, and broadcast addresses. Then they’ll explore Ethernet standards and Ethernet frame structures, as well as Ethernet equipment. ICT professionals learn about Ethernet connectors and performance issues associated with Ethernet communication. They will also learn about Ethernet switches and the benefits of switching. Then they’ll explore switch functionality, connectivity issues surrounding switching, and spanning tree protocol. ICT professionals will go onto discover how to configure switches and the importance of port security. Finally, they’ll learn about Power Over Ethernet (POE), port mirroring, and Virtual LANs (VLANs). This course was originally created by Global Knowledge (GK). This course provides an overview of how the predominant technology that fuels network connections is Ethernet. Switching is the process of sending networking signals to the right destination.
