Create and Configure a Logical Network and IP Address Pool (Script)

Logical networks enable network administrators to model the network based on recognizable categories that align to business needs by grouping together subnets and VLANs. After you create a new logical network, use the logical network definition, also called a network site, to assign IP subnets and VLANs to the logical network.

You can create a static IP address pool and associate it with one or more host groups. After you have created a static IP address pool, you can add DNS servers to it by using the Set-SCStaticIPAddressPool cmdlet.

For more information about configuring networking in System Center 2012 – Virtual Machine Manager, see Configuring Networking in VMM.

Disclaimer

The following script creates and configures a logical network and a static IP address pool. The script assumes that you have already created a host group named Seattle.

  
# Description:   This script creates a logical network and then creates a logical   
#                network definition that it applies it to the logical network.  
#                The script then creates a static IP address pool, associates   
#                the pool with a host group, and adds DNS servers.   
  
# Create a logical network.  
$LogicalNetwork = New-SCLogicalNetwork -Name "FrontEnd"  
  
# Create a logical network definition and associate it with the new logical network.  
$HostGroup = Get-SCVMHostGroup | where { $_.Path -eq "All Hosts\Seattle" }  
$SubnetVLAN = New-SCSubnetVLAN -Subnet "10.0.0.1/24" -VLAN 25  
$LogNetDef = New-SCLogicalNetworkDefinition -Name "Logical Network Definition for Seattle" -LogicalNetwork $LogicalNetwork -VMHostGroup $HostGroup -SubnetVLAN $SubnetVLAN  
  
# Create a static IP address pool and associate it with a host group.  
$HostGroup = Get-SCVMHostGroup | where { $_.Path -eq "All Hosts\New York\Production" }  
$DefaultGateway = New-SCDefaultGateway -IPAddress "10.0.0.1" -Metric 10  
$IPPool = New-SCStaticIPAddressPool -LogicalNetworkDefinition $LogNetDef -Name "Production IP Address Pool" -Description "This IP address pool is for production use in Seattle." -Subnet "10.0.0.0/24" -IPAddressRangeStart "10.0.0.10" -IPAddressRangeEnd "10.0.0.99" -IPAddressReservedSet "10.0.0.25-10.0.0.35, 10.0.0.38" -VIPAddressSet "10.0.0.95-10.0.0.99" -DNSSuffix "domain.contoso.com" -DNSSearchSuffix domain1.contoso.com, domain2.contoso.com -DNSServer "10.0.0.1", "10.0.0.2" -WINSServer "10.0.0.1", "10.0.0.2" -DefaultGateway $DefaultGateway -EnableNetBIOS $True  
  
# Add DNS servers to the static IP address pool.  
$DNSServerIPAddress = $IPPool.DNSServers  
$DNSServerIPAddress += "10.0.0.5"  
Set-SCStaticIPAddressPool -StaticIPAddressPool $IPPool -DNSServer $DNSServerIPAddress
