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

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.


Expected Duration
174 minutes

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.


Describing Data Center vPCs and FabricPath

  • start the course
  • describe the benefits of Layer 2 vPCs
  • describe dual-sided vPCs on the Cisco Nexus 7000 and 5000 Series Switches
  • describe the vPC peer, vPC peer link, and fabric service components of the vPC architecture
  • describe the vPC keepalive links, vPC, and vPC member port components of the vPC architecture
  • describe the vPC domain, orphan device and port components of the vPC architecture
  • describe the role of the vPC peer link in vPC data plane operations
  • describe how Cisco Fabric Services is used as the primary control plane protocol for vPC
  • identify the limitations that should be considered when deploying vPCs
  • verify vPCs on the Cisco Nexus 7000 and 5000 Series Switches
  • describe the use of the STP tree in FabricPath loop prevention
  • recognize how FabricPath handles equal cost path links
  • describe how FabricPath uses the IS-IS protocol for control plane operations
  • describe conversational MAC address learning
  • match the Classic Ethernet and Cisco FabricPath modes to their functions
  • verify correct operation of Cisco FabricPath on the Cisco Nexus 7000 and 5500 Platform switches

Using OTV on Cisco Nexus 7000 Series Switches

  • describe issues that can occur in a data center cloud
  • describe traditional Layer 2 DCI solutions
  • describe how Overlay Transport Virtualization overcomes the challenges of traditional layer 2 solutions
  • match the OTV technology term to its function
  • sequence the steps in OTV data plane forwarding operations
  • describe OTV control plane operations
  • describe Spanning Tree and OTV operations
  • identify how the OTV control protocol handles unknown unicasts and ARP caching
  • describe how multihoming is automated with OTV
  • match the show commands used to verify OTV on the Cisco Nexus Switches with their description

Practice: Reviewing FabricPath and OTV

  • describe the use and validation of vPC and Cisco FabricPath, and verify OTV in the data center
