Configuring Logical Networking in VMM Illustrated Overview

The following illustration shows a logical network in VMM in either System Center 2012 or System Center 2012 SP1. For some networking elements, fictitious names such as “Contoso1” are included to help illustrate the purpose of those elements.

Figure 1   Logical network

This illustration shows how a logical network in VMM is a container for network sites (also called logical network definitions) and IP subnet information, virtual local area network (VLAN) information, or both. It also shows how host groups in VMM can be associated with a network site and how IP address pools can be assigned to subnets within the logical network.

In the preceding illustration, the names of elements that you configure by running a wizard or opening a property sheet are shown in bold text, while elements that are on a page of the wizard or on a tab of the property sheet are shown without bold text.

The following illustration shows the network object model for logical networks in VMM in System Center 2012 and System Center 2012 SP1. The illustration shows the relationships among network objects only, rather than indicating information about the wizards and property sheets through which the objects are configured in the VMM console. The illustration can be especially useful if you are learning about configuring VMM through Windows PowerShell scripts, which reflect the network object models directly.

For some objects, sample names such as “Contoso1” and “Building1” are included to help illustrate the purpose of those objects. (The object labeled “Network site” is also known as a “logical network definition.”)

The following key explains the notations on the arrows:

• 1-1 means “one to one.”
  
  
• 1-M means “one to many.”
  
  
• M-M means “many to many.”
  
  

In the preceding illustration, bold text is used for each VMM object name, regardless of how that object is configured through the VMM console.
