Add-DhcpServerv4Reservation

Add-DhcpServerv4Reservation is accessible with the help of DHCPServer module. To configure DHCPServer, go through this link.

Synopsis

Reserves the specified IPv4 address in the scope for a client.

Description

The Add-DhcpServerv4Reservation cmdlet reserves the specified IPv4 address in the scope for a client. Once reserved, the IP address will be leased only to the client identified by the specific client identifier (ID).

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.

-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.

-ClientId

Specifies the unique identifier (ID) for the client. For Windows clients, the MAC address is used as the client ID.

-ComputerName

Specifies the DNS name, or IPv4 or IPv6 address, of the target computer that runs the Dynamic Host Configuration Protocol (DHCP) server service.

-Confirm

Prompts you for confirmation before running the cmdlet.

-Description

Specifies the description for the reservation to created.

-IPAddress

Specifies the IPv4 address to reserve for the client.

-Name

Specifies the name of the reservation created. This parameter value can be the host name of the client or a name to identify the reservation on the DHCP server service.

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

-ScopeId

Specifies the identifier (ID) of the scope in which the reservation is created.

-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.

-Type

Specifies the type of client request for which this IP address is reserved. The acceptable values for this parameter are: DHCP, BootP, or Both. The default value is Both.

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Add-DhcpServerv4Reservation [-ComputerName <String>] [-ScopeId] <IPAddress> [-IPAddress] <IPAddress> [-ClientId] <String> [-Name <String>] [-Description <String>] [-Type <String>] [-PassThru] [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm] [<CommonParameters>]

———————-EXAMPLE 1———————-
PS C:> Add-DhcpServerv4Reservation -ScopeId 192.168.10.0 -IPAddress 192.168.10.33 -ClientId 00-0C-29-00-B2-33 -Description “Reservation for Bot server”
This example adds a reserved IP address for the client identified by the specified client ID.

———————-EXAMPLE 2———————-
PS C:>Import-Csv –Path Reservations.csv | Add-DhcpServerv4Reservation -ComputerName dhcpsrv.TOSSolution.com
This example adds all of the reservations in the file named Reservations.csv to the DHCP server service running on the computer named dhcpsrv.TOSSolution.com. The Import-Csv cmdlet returns the objects with reservation fields and pipes the objects to this cmdlet, which adds these reservations to the DHCP server services. The file named Reservations.csv should contain the reservations in the following comma-separated values (CSV) format:
ScopeId,IPAddress,Name,ClientId,Description
10.10.10.0,10.10.10.10,comp1,1a-1b-1c-1d-1e-1f,Reserved for comp1
20.20.20.0,20.20.20.11,comp2,2a-2b-2c-2d-2e-2f,Reserved for comp2
30.30.30.0,30.30.30.12,comp3,3a-3b-3c-3d-3e-3f,Reserved for comp3
