DCICN 1.0: Switched Networks

Datacenter network engineers and learners embarking on a network administration or engineering career who wish to expand their skills in datacenter networks


Expected Duration
131 minutes

LANs are a relatively low-cost means of sharing expensive resources and they have rapidly evolved into support systems that are critical to communications within an organization. It is important that you understand how elements that govern switching technology elements interact. In this course, you will learn about the challenges that shared LANs face as they confront the increasing need for bandwidth and speed to satisfy the needs of multiple users, and about host-to-host communications in a switched network. In this course, you will also learn how to describe the features and capabilities of the Cisco NX-OS Software. The Cisco Nexus Operating System (NX-OS) Software is a datacenter-class operating system that is built with modularity and resiliency at its foundation. Cisco NX-OS provides a rich feature set that fulfills the routing, switching, security, and operations requirements of present and future datacenters. To complete the course, you will learn to set up a console connection between a Cisco Nexus switch and a terminal, and perform basic CLI commands. This course is one of a series in the Skillsoft learning path that covers the objectives for Cisco exam 640-911: Introducing Cisco Data Center Networking.
