Description

The Get-DhcpServerv4Reservation cmdlet gets one or more IPv4 reservations for the specified IP addresses or client identifiers (IDs). If only the ScopeId parameter is specified, all of the IPv4 reservations from the specified scope are returned.

Examples

Example 1: Get reservations in a specified scope 

PS C:\> Get-DhcpServerv4Reservation -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0

This cmdlet gets all of the reservations present in the specified scope on the specified DHCP server service that runs on the computer named dhcpserver.contoso.com.

Example 2: Get a reservation for a specified client 

PS C:\> Get-DhcpServerv4Reservation -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0 -ClientId "F0-DE-F1-7A-00-5E"

This cmdlet gets the reservation present in the specified scope for specified client ID.

Example 3: Get a reservation information for a specified address 

PS C:\> Get-DhcpServerv4Reservation -ComputerName "dhcpserver.contoso.com" -IPAddress 10.10.10.5

This cmdlet gets the reservation information for specified IP address.

Example 4: Get all reservations for all scopes 

PS C:\> Get-DhcpServerv4Scope -ComputerName dhcpserver.contoso.com | Get-DhcpServerv4Reservation -ComputerName dhcpserver.contoso.com

This cmdlet gets all the reserved IP addresses from all of the scopes on the server dhcpserver.contoso.com. The Get-DhcpServerv4Scope cmdlet returns all of the scope objects and pipes the objects into this cmdlet, which returns the reservations from all the scopes.

Required Parameters

-ClientId

Specifies one or more client IDs of the reservations which need to be retrieved. For Windows clients, the MAC address is the client ID.

Type: String[]
Position: 2
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
-IPAddress

Specifies one or more IPv4 addresses of the reservations which are to be retrieved.

Type: IPAddress[]
Aliases: ReservedIP
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
-ScopeId

Specifies the scope ID, in IPv4 address format, from which the reservations are to be retrieved.

Type: IPAddress
Aliases: ReservationScopeID
Position: 1
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

Optional 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 .

Type: SwitchParameter
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-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.

Type: CimSession[]
Aliases: Session
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-ComputerName

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

Type: String
Aliases: Cn, ReservationServer
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-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: Int32
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
