ACI Operations & Troubleshooting Boot Camp (ACI OT BC)

Course Overview

This three-day ILT course is designed for Network Engineers who need to know how to operate and troubleshoot Data Center Network Infrastructure running Cisco ACI. This course will cover material from an Operations (Day 0/1/2/n) perspective, discussing best practices, caveats and common issues.

Incorporating the latest software, hardware, and techniques, this course dives deep into the wealth of management and troubleshooting capabilities in Cisco ACI. Students will practice on the whole range of operations tools, including configuration management, performance tracking, and troubleshooting. Lots of troubleshooting. On Day 3 the instructor will inject various faults into the lab fabric, and students will need to apply the lessons of this course to resolve the issues in a live Challenge Lab.

The curriculum is delivered as Just-In-Time learning, designed to provide Engineers just what they need to know, just when they need to know it. This is production-focused training, based on battle-tested lessons learned from over 100 production deployments.
