Cisco ACI Operations and Troubleshooting (ACIOPS v3.1)

Cisco ACI Operations and Troubleshooting (ACIOPS v3.1)

The Cisco ACI Operations and Troubleshooting (ACIOPS v3.1) is a five (5) day course that reviews topics that are covered extensively in the Data Center Application Centric Infrastructure Fundamentals (DCACIFv3.1) course.
The course covers the basic concepts of the graphical user interface (GUI) setup of the fabric. The focus is on building Tenants, VRF's, Bridge Domains, EPG's and Contracts based on a practical design.
The physical, VMM, L2 and L3 Domains and a good understanding of the flow of the GUI is paramount in applying this knowledge in automation.

The programmability of Cisco ACI is also reviewed in this course, specifically the REST and JSON APIs, and the APIC Object-Based Tree and dMIT queries.
This course also includes some advanced operational features such as, firmware upgrades, performing backups, snapshots, and rollbacks.  We will also examine how to use fault health checks and other ACI troubleshooting tools.
