Course Overview
The Campus track is divided into two distinct sub-tracks: Operations and Engineering. Operations focus on Day-2 tasks such as telemetry and troubleshooting, while Engineering concentrates on the design and architecture of L2 campus networks. Both tracks include hands-on labs with a focus on the distinct tasks for each of these roles. The Arista Academy Campus course equips network professionals with the knowledge and skills required to configure, troubleshoot, and manage Arista Layer 2 and 3 Campus network designs. You will explore key topics such as Arista Campus Architecture, CloudVision (CVP/CV-CUE), Layer 2 and 3 Wired Campus Networks, Wireless Fundamentals, Campus Wireless Deployment, and Campus Security. This course also includes hands-on labs to reinforce theoretical knowledge with practical application. This is a 5-day Instructor-Led Training (ILT).
