VMware NSX Cookbook

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.

Restoring NSX Controller Nodes


The NSX Controller Nodes do not need to be backed up, as they retrieve the configuration from NSX Manager. In the case where NSX controllers were deleted, are missing from the configuration/UI, failed to re-join the cluster, or we are experiencing multiple controller failure, the NSX Controller Nodes can be restored by redeploying a new set of NSX Controller Nodes.

Note

The supported procedure to redeploy NSX Controller Nodes is to delete all three existing controller nodes, deploy three new controller nodes, and perform a controller state update.

Getting ready

Before redeploying the controller nodes, first delete the existing failed controller nodes from the NSX deployment. You should be logged into the vSphere Web Client as an Enterprise Administrator or NSX Administrator.

Note

When there are no NSX Controller Nodes in the system, the hosts operate in "headless" mode. New VMs or vMotioned VMs will have networking issues until new controllers are deployed and the...
