Syntax

Parameter Set: Get1
Get-DhcpServerv4OptionDefinition [[-OptionId] <UInt32[]> ] [[-VendorClass] <String> ] [-All] [-AsJob] [-CimSession <CimSession[]> ] [-ComputerName <String> ] [-ThrottleLimit <Int32> ] [ <CommonParameters>]

Detailed Description

The Get-DhcpServerv4OptionDefinition cmdlet gets the DHCPv4 option definitions for the specified option identifiers (IDs).

If the OptionId parameter is not specified, then all of the option definitions, which are not vendor specific, are returned. The VendorClass parameter acts as a filter for option definitions for the specified vendor class only.

If the All parameter is specified, then all of the option definitions including the vendor class specific option definitions will be returned.

If the All and OptionId parameters are specified, then all of the option definitions including the vendor class specific option definitions with the specified option ID will be returned.

If the All and the VendorClass parameters are specified, then the All parameter is ignored.

Parameters

-All

Gets all of the option definitions on the DHCP server service including vendor specific option definitions.

-AsJob

-CimSession<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.

-ComputerName<String>

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

-OptionId<UInt32[]>

Specifies the numerical identifiers of the options for which the option definitions are requested. If nothing is specified, then all of the DHCPv4 option definitions are returned.

-ThrottleLimit<Int32>

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.

-VendorClass<String>

Returns the option definitions only for the specified vendor class.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).
