Switching Fundamentals

This course is included in our On-demand training solution.


Using switches to connect devices within an enterprise creates a microsegmented network domain where all devices can communicate freely. Switches offer a wide range of speeds and technologies suitable for any modern Ethernet challenge. Engineers who understand how switches operate are much more likely to be able to successfully troubleshoot networks. In this course, you’ll learn about the fundamentals of Ethernet switching and management of switches. This course is one of a series in the Skillsoft learning path that covers the objectives for the Cisco exam Building Cisco Service Provider Next-Generation Networks Part 1 exam (640-875 SPNGN1). This exam counts toward the CCNA Service Provider certification.

Target Audience

This course is targeted at networking engineers who must interface with Cisco IOS, IOS XR and IOS XE devices. Additionally, those who have a need to understand technologies used in the service provider realm will benefit.



Expected Duration

90 min.
