All SLI Scheduled Dates Are Guaranteed to Run!
This four-day ILT course is designed to take Field Engineers and System Architects with no ACI experience and prepare them to design and build an ACI fabric. Students will learn what they need to know to take Cisco switches from the loading dock and build an operational, functioning ACI fabric that includes servers, virtual machines, external networks and service devices.
Specific topics addressed in this course are ACI configuration and basic operations, including rack-and-stack initial installation, application profile configuration, ACI under-the-hood, VMware hypervisor integration, external connectivity, layer 4-7 service device integration, operations and troubleshooting. There are detailed labs for each step of the course.
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. Students are not given training that they are not able to apply immediately. With this production-focused training, the student will be ready for the technical requirements of today. With the included library of curated references, the student is also poised to meet the requirements of the future.
The course provides insight from subject matter experts and over 100 production installations. These subject matter experts have insight because they’ve been in the students’ shoes.
