Overview of this book

VMware NSX is at the forefront of the software-defined networking revolution. It makes it even easier for organizations to unlock the full benefits of a software-defined data center – scalability, flexibility – while adding in vital security and automation features to keep any sysadmin happy. Software alone won’t power your business – with NSX you can use it more effectively than ever before, optimizing your resources and reducing costs. Getting started should be easy – this guide makes sure it is. It takes you through the core components of NSX, demonstrating how to set it up, customize it within your current network architecture. You’ll learn the principles of effective design, as well as some things you may need to take into consideration when you’re creating your virtual networks. We’ll also show you how to construct and maintain virtual networks, and how to deal with any tricky situations and failures. By the end, you’ll be confident you can deliver, scale and secure an exemplary virtualized network with NSX.

NSX user world agents


NSX Manager is responsible for deploying the NSX Controller cluster, ESXi hosts preparation by pushing vSphere Installation Bundles (VIBs) to enable VXLAN, distributed routing, distributed firewall, and a user world agent used to communicate at the control-plane level. The functionality of the user world agent is highly critical and any failures will have a direct impact on the control plane learning, which eventually affects data plane traffic. So, let's discuss these agents, along with basic health checks and log locations.

netcpa

It is a user world agent that communicates with NSX control plane, and the netcpa service should be up and running on the NSX-prepared ESXi host. If the functionality is impacted, we will certainly experience routing and switching issues in the NSX environment, and the ESXi host won't learn new routes from the time the netcpa service was down. So, this is extremely important: creating the routes alone on an NSX Edge VM won't do the trick;...
