[<CommonParameters>] The Add-DhcpServerv4Reservation cmdlet reserves the specified IPv4 address in the scope for a client. Once reserved, the IP address is leased only to the client identified by the specific client identifier (ID).
PS C:\> Add-DhcpServerv4Reservation -ScopeId 10.10.10.0 -IPAddress 10.10.10.8 -ClientId "F0-DE-F1-7A-00-5E" -Description "Reservation for Printer"This example adds a reserved IP address for the client identified by the specified client ID.
PS C:\> Import-Csv -Path "Reservations.csv" | Add-DhcpServerv4Reservation -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 services. The file that is 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,Computer1,1a-1b-1c-1d-1e-1f,Reserved for Computer1
20.20.20.0,20.20.20.11,Computer2,2a-2b-2c-2d-2e-2f,Reserved for Computer2
30.30.30.0,30.30.30.12,Computer3,3a-3b-3c-3d-3e-3f,Reserved for Computer3
PS C:\> Get-DhcpServerv4Lease -ComputerName "dhcpserver.contoso.com" -IPAddress 10.10.10.11 | Add-DhcpServerv4Reservation -ComputerName "dhcpserver.contoso.com"This example converts one of the leases into a reservation. The Get-DhcpServerv4Lease cmdlet returns the IP address lease object and pipes the object to this cmdlet, which creates the reservation with the IP address and client ID in the lease object.
PS C:\> $FreeIP = Get-DhcpServerv4FreeIPAddress -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0
PS C:\> Add-DhcpServerv4Reservation -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0 -IPAddress $FreeIP -ClientId "F0-DE-F1-7A-00-5E" -Description "Reservation for Printer"This example creates a reservation for the client identified by the specified client ID from any of the free IP addresses in the scope 10.10.10.0. The Get-DhcpServerv4FreeIPAddress cmdlet gets a free IP address in the scope, and then this cmdlet reserves an address for the specified client ID.
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.
