ACI-TSO: Cisco ACI Troubleshooting and Operations Workshop

   Description

With the advent of software based network deployment and ACI, the approach needed for day to day operations and troubleshooting requires adapting. The introduction of a new suite of tools specific ACI of has made trouble shooting and operating more flexible and powerful. Integrating a new and comprehensive system into an array of differing customer environments potentially leads to operational challenges. An extended set of skills is needed to ensure these challenges are addressed and the ACI deployment is a success.

The Cisco ACI Troubleshooting and Operations Workshop (ACI-TSO) provides network engineers with the skills and insight into how best to troubleshoot and manage a new or existing ACI environment.

The workshop is a combination of theory and lab exercises that configure, operate and troubleshoot the ACI environment. The majority of the time is hands and includes the use of the Housley developed orchestrator that builds trouble tickets for the students to explore and solve

   Objective

  • Review ACI Architecture and Concepts
  • Review common task needed to manage an ACI environment
  • Detail the tools available in ACI environment that are available to the Network Engineer
  • Detail how to interrogate ACI for existing and potential issues
  • Look at common issues and solutions
  • Look into external tools that enhance ACI operations
  • Know that there is more to learn
