NAME New-NetVirtualizationLookupRecord



SYNOPSIS

Creates a policy entry for an IP address in a virtual network.





SYNTAX

New-NetVirtualizationLookupRecord [-CimSession <CimSession[]>] [-Context <String>] [-CustomerID <String>]

[-ThrottleLimit <Int32>] [-Type {Static | Dynamic | GatewayWildcard | L2Only}] [-UseVmMACAddress <Boolean>]

[-VMName <String>] -CustomerAddress <String> -MACAddress <String> -ProviderAddress <String> -Rule

{TranslationMethodNat | TranslationMethodEncap | TranslationMethodNone} -VirtualSubnetID <UInt32>

[<CommonParameters>]





DESCRIPTION

The New-NetVirtualizationLookupRecord cmdlet creates a lookup record policy entry for an IP address that belongs

to a Microsoft???? Hyper-V???? Server 2016 virtual network. Network Virtualization allows for more than one virtual

network to exist on the same physical network. Computers can exchange network traffic with a virtual machine by

using a Customer Address in the virtual network. Network Virtualization manages the Provider Addresses that are

the physical network addresses. This cmdlet creates a record that maps a Customer Address to a Provider Address.

For more information, see Network Virtualization technical details

(http://technet.microsoft.com/library/jj134174.aspx) on TechNet.



To create a policy entry, you must specify a Customer Address, a virtual machine media access control (MAC)

address, a Provider Address, a rule type, and a virtual subnet ID. You can also specify a context, a customer ID,

and a virtual machine name in addition to whether to use a virtual machine virtual MAC address.





PARAMETERS

-CimSession [<CimSession[]>]

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such

as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local

computer.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-Context [<String>]

Specifies a comment regarding the policy entry. Administrators can use this comment for any purpose.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-CustomerAddress <String>

Specifies the IP address for a virtual machine. You can use can use either an IPv4 or IPv6 address.



Required? true

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-CustomerID [<String>]

Specifies an ID for a policy entry or virtual machine. Administrators can use this setting for any purpose.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-MACAddress <String>

Specifies a MAC address that corresponds to the Customer Address.



Required? true

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-ProviderAddress <String>

Specifies an IP address, either IPv4 or IPv6, for a physical address that corresponds to the Customer Address.



Required? true

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-Rule <RuleType>

Specifies which type of virtualization mechanism that the policy entry uses. The acceptable values for this

parameter are:



-- TranslationMethodNat. IP address rewrite.

-- TranslationMethodEncap. Network Virtualization Generic Routing Encapsulation (NVGRE).

-- TranslationMethodNone. None.



Required? true

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-ThrottleLimit [<Int32>]

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this

parameter is omitted or a value of 0 is entered, then Windows PowerShell???? calculates an optimum throttle limit

for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies

only to the current cmdlet, not to the session or to the computer.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-Type [<Type>]

Specifies a type. The type determines the address mapping for a record. The acceptable values for this

parameter are:



-- Static. The Customer Address (CA) specified in this lookup record is the address assigned to the

corresponding virtual machine, which is implicitly specified by the MAC address. An administrator or vmmblue_1

creates this lookup record.

-- Dynamic. The Customer Address specified in this lookup record is the address assigned to the corresponding

virtual machine, which is implicitly specified by the MAC address. For example, the Hyper-V Network

Virtualization software creates this record for virtual machines that obtain their IP addresses from a DHCP

server.

-- L2Only. The Customer Address specified in this lookup record should be set to 0.0.0.0 for IPv4, or :: for

IPv6. The corresponding virtual machine, implicitly specified by the MAC address, learns the CA dynamically.

-- GatewayWildcard. The CA address specified in this lookup record should be set to 0.0.0.0 for IPv4, or ::

for IPv6. The corresponding virtual machine, implicitly specified by the MAC address, is a Hyper-V Network

Virtualization gateway.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-UseVmMACAddress [<Boolean>]

Indicates whether this entry uses its defined MAC address instead of physical MAC address. Virtual networking

can use different MAC addresses for different virtual machines to balance traffic among multiple CPU cores.



A value of $True is valid only if the Rule parameter has a value of TranslationMethodNat. The default value

for this setting is $False.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-VirtualSubnetID <UInt32>

Specifies an ID for the virtual subnet that the Customer address belongs to. The acceptable values for this

parameter are: integers from 4096 through 16777214.



Required? true

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-VMName [<String>]

Specifies a name for the virtual machine for this policy entry. Administrators can use this name for any

purpose.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,

ErrorAction, ErrorVariable, WarningAction, WarningVariable,

OutBuffer, PipelineVariable, and OutVariable. For more information, see

about_CommonParameters (https:/go.microsoft.com/fwlink/?LinkID=113216).



INPUTS









OUTPUTS









Example 1: Create a policy entry



PS C:\\> New-NetVirtualizationLookupRecord -CustomerAddress "10.0.0.5" -MACAddress "101010101105" -ProviderAddress

"192.168.1.101" -Rule "TranslationMethodEncap" -VirtualSubnetID "6000" -VMName "BlueS1-VM1"



This command creates a policy entry for a Customer Address 10.0.0.5. The command specifies the required values: a

MAC address for the virtual machine, the physical Provider Address, a rule type, and a virtual subnet ID. The rule

type is TranslationMethodEncap, which means the entry uses NVGRE. The command also specifies a name for the

virtual machine.
