Overview of this book

This book begins with a brief introduction to VMware's NSX for vSphere Network Virtualization solutions and how to deploy and configure NSX components and features such as Logical Switching, Logical Routing, layer 2 bridging and the Edge Services Gateway. Moving on to security, the book shows you how to enable micro-segmentation through NSX Distributed Firewall and Identity Firewall and how to do service insertion via network and guest introspection. After covering all the feature configurations for single-site deployment, the focus then shifts to multi-site setups using Cross-vCenter NSX. Next, the book covers management, backing up and restoring, upgrading, and monitoring using built-in NSX features such as Flow Monitoring, Traceflow, Application Rule Manager, and Endpoint Monitoring. Towards the end, you will explore how to leverage VMware NSX REST API using various tools from Python to VMware vRealize Orchestrator.

Enabling the Controller Disconnected Operation Mode on a Transport Zone


As covered in the introduction, CDO mode provides additional control plane resiliency during controller connectivity and controller cluster unavailability. With CDO mode enabled, VMs can be moved between ESXi hosts without data plane disruption, even if the whole controller cluster is down. In this recipe, we will show you how to enable CDO mode on a transport zone in NSX.

Getting ready

CDO mode is disabled by default in NSX. To enable CDO mode, the following prerequisites need to be satisfied:

  • NSX is running on Version 6.3.0 or later
  • The vSphere cluster has been prepared for NSX with VXLAN configured
  • The NSX transport zone has been created
  • The vSphere cluster has been added into the NSX transport zone

Note

For the universal transport zone, CDO mode can only be enabled from the Primary NSX Manager.

How to do it...

Follow these steps to enable CDO mode in a transport zone.
