Troubleshooting the Cisco ACI

Duration: 
2 days
Codes: 
TBLCACIF,ACI

Overview

Classic data centers integrate many different components from many different environments, creating a very complex and decentralized approach to troubleshooting application deployment. Just as ACI allows for centralized management focused on application needs, you can troubleshoot your Application Centric Infrastructure (ACI) fabric from a centralized location with the requirements of the application in mind.

The first step in any troubleshooting scenario is to fully understand your existing ACI environment. In this two day course, you have the option of configuring your own fabric as a foundation for the troubleshooting labs or discover a pre-built environment. Either path is designed to help you better understand your existing environment and is key to troubleshooting any problem.

You will use common ACI troubleshooting tools, such as Visore, API Inspector, and various show commands to identify problems that impact fabric-wide connectivity. You will use the APIC CLI to expose misconfigurations that trigger fault messages in the APIC GUI and practice applying GUI and CLI tools to various troubleshooting scenarios.

Audience

Anyone looking to gain an understanding of how to troubleshoot an ACI Fabric, including tools such as Viscore and API Inspector.
