Add-DhcpServerv6Reservation

  • Reference
Module:
DhcpServer

Adds an IPv6 Reservation to an IPv6 prefix or scope.

Syntax

Add-DhcpServerv6Reservation
   [-ComputerName <String>]
   [-IPAddress] <IPAddress>
   [-ClientDuid] <String>
   [-Iaid] <UInt32>
   [[-Name] <String>]
   [-Description <String>]
   [-Prefix] <IPAddress>
   [-PassThru]
   [-CimSession <CimSession[]>]
   [-ThrottleLimit <Int32>]
   [-AsJob]
   [-WhatIf]
   [-Confirm]
   [<CommonParameters>]

Description

The Add-DhcpServerv6Reservation cmdlet reserves a specified IPv6 address for the client identified by the specified Dynamic Host Configuration Protocol (DHCP) v6 unique identifier (ID) (DUID) and identity association ID (IAID).

Examples

Example 1: Reserve an IP address

PS C:\> Add-DhcpServerv6Reservation -Prefix 2001:4898:7020:1020:: -IPAddress 2001:4898:7020:1020::1 -ClientDuid "00-01-00-01-15-F9-7F-AB-F0-DE-F1-7A-00-5E" -Iaid 234890455

This example reserves the specified IPv6 address for the specified ClientDuid and Iaid parameter values. After the reservation is added, the DHCP server service assigns only the specified IP address to the client request which contains the specified ClientDuid and Iaid parameter values.

Example 2: Reserve IP addresses from a file

PS C:\> Import-Csv -Path "Reservations.csv" | Add-DhcpServerv6Reservation -ComputerName "dhcpserver.contoso.com"

This example adds all of the reservations in the file that is named Reservations.csv to the DHCP server service that runs on the computer named dhcpserver.contoso.com. The Import-Csv cmdlet returns the objects that have reservation fields and pipes the objects to this cmdlet, which adds these reservations to the DHCP server service. The file that is named Reservations.csv should contain the reservations in the following comma-separated values (CSV) format:

Prefix,IPAddress,Name,ClientDuid,Iaid,Description 2001:4898:7020:1020::,2001:4898:7020:1020::1,Computer1,00-01-00-01-15-F9-7F-AB-F0-DE-F1-7A-00-5E,234890455,Reserved for Computer1 2001:4898:7020:1020::,2001:4898:7020:1020::2,Computer2,00-01-00-01-15-F9-7F-AB-F0-DE-F1-7A-00-6E,234890465,Reserved for Computer2 2001:4898:7020:1020::,2001:4898:7020:1020::3,Computer3,00-01-00-01-15-F9-7F-AB-F0-DE-F1-7A-00-7E,234890475,Reserved for Computer3

Example 3: Reserve any IP address in a scope

PS C:\> $FreeIP = Get-DhcpServerv6FreeIPAddress -ComputerName "dhcpserver.contoso.com" -Prefix 2001:4898:7020:1020::
PS C:\> Add-DhcpServerv6Reservation -ComputerName "dhcpserver.contoso.com" -Prefix 2001:4898:7020:1020::  -IPAddress $FreeIP -ClientDuid "00-01-00-01-15-F9-7F-AB-F0-DE-F1-7A-00-5E" -Iaid 234890455 -Description "Reservation for Printer"

This example creates a reservation for the client identified by the specified client ID from any of the free IP address in the scope 2001:4898:7020:1020::. The Get-DhcpServerv6FreeIPAddress cmdlet fetches a free IP address in that scope, and then this cmdlet reserves the IP address for the specified client ID.

Example 4: Convert a lease into a reservation

PS C:\> Get-DhcpServerv6Lease -ComputerName "dhcpserver.contoso.com" -IPAddress 2001:4898:7020:1020::11 | Add-DhcpServerv6Reservation -ComputerName "dhcpserver.contoso.com" -Prefix 2001:4898:7020:1020::

This example converts one of the leases into a reservation. The Get-DhcpServerv6Lease cmdlet returns an IP address lease object and pipes the object to this cmdlet, which creates the reservation with the IP address, client DUID, and IAID in the lease object.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

-ThrottleLimit

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.
