Description

The Remove-DhcpServerv4OptionValue cmdlet deletes one or more IPv4 option values at the server, scope or reservation level, either for the standard IPv4 options or for the specified vendor or user class.

If you specify only the ReservedIP parameter, the option values set at the reservation level are deleted. If you specify only the ScopeId parameter, the option values set at the scope level are deleted. If you specify neither the ScopeId nor the ReservedIP parameter, the option values set at the server level are deleted. The ScopeId and the ReservedIP parameters cannot both be specified.

The UserClass and PolicyName parameters cannot both be specified.

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.

-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

Default value:None
Accept pipeline input:False
