Switch Troubleshooting and Routing Fundamentals

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


Because switches have a broad spectrum of features, troubleshooting those features is extraordinarily complex. Those who can troubleshoot switches effectively can resolve issues quickly and positively affect the availability of a network. Today’s modern switches are also often capable of supporting routing operation. This added functionality provided by multilayer switches adds another layer of complexity to working with these devices. Whether working with routing on a traditional chassis or a multilayer switch chassis, a mastery of the fundamentals of routing is required to navigate the challenges presented in a larger routing domain. This course covers troubleshooting switch connectivity as well as the fundamentals of routing operation. 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.
