Overview of this book

VMware vSphere PowerCLI, a free extension to Microsoft Windows PowerShell, enables you to automate the management of a VMware vSphere or vCloud environment. This book will show you how to automate your tasks and make your job easier. Starting with an introduction to the basics of PowerCLI, the book will teach you how to manage your vSphere and vCloud infrastructure from the command line. To help you manage a vSphere host overall, you will learn how to manage vSphere ESXi hosts, host profiles, host services, host firewall, and deploy and upgrade ESXi hosts using Image Builder and Auto Deploy. The next chapter will not only teach you how to create datastore and datastore clusters, but you’ll also work with profile-driven and policy-based storage to manage your storage. To create a disaster recovery solution and retrieve information from vRealize Operations, you will learn how to use Site Recovery Manager and vRealize Operations respectively. Towards the end, you’ll see how to use the REST APIs from PowerShell to manage NSX and vRealize Automation and create patch baselines, scan hosts against the baselines for missing patches, and re-mediate hosts. By the end of the book, you will be capable of using the best tool to automate the management and configuration of VMware vSphere.

Managing NSX logical switches


NSX logical switches are distributed switches just like vSphere distributed switches. Each logical switch is mapped to a unique Virtual eXtensible LAN (VXLAN). The VXLAN carries the virtual machine traffic over the physical network. The physical network can be a routed OSI layer three network. All the ESXi hosts in a vSphere cluster can share one or more NSX logical switches.

In the following sections, Creating NSX logical Switches , Retrieving NSX logical switches , and Removing NSX logical switches , you will learn to create, retrieve, and remove NSX logical switches using the NSX REST API.

Creating NSX logical switches

In the following screenshot of the vSphere Web Client, you can see that in order to create a new NSX logical switch you have to specify a name, transport zone, and the replication mode. Optionally, you can specify a description, enable IP discovery, and enable MAC learning.
