Cisco DCICT 1.0 – Describing vPCs, Cisco FabricPath, and OTV in the DataCenter

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


Cisco FabricPath and virtual port channels (vPCs) can be used to provide a Layer 2 multipathing solution for the data center. Cisco Overlay Transport Virtualization (OTV) is a MAC in IP technique for supporting the extension of Layer 2 VLANs over any transport that can forward IP packets. In this course, you will learn about vPCs and Cisco Fabric Path and how to verify their operation on Cisco Nexus 7000 and 5000 Series Switches, as well as explore OTV as a method of data center interconnect (DCI). This course is one of a series in the Skillsoft learning path that covers the objectives for Cisco exam 640-916: Introducing Cisco Data Center Technologies.

Target Audience

This course is targeted toward data center network engineers and learners embarking on a network administration or engineering career who wish to understand all the components that make up a real-world data center. In addition, anyone interested in the DCICT CCNA Data Center certification exam will benefit from this course. This course offers the official training for the Introducing Cisco Data Center Technologies (640-916 DCICT) certification exam which is a component exam for the CCNA Data Center certification.
