Get-DhcpServerv4OptionValue

Get-DhcpServerv4OptionValue

Returns the IPv4 option Values for one or more IPv4 options at the server, scope or reservation level.

Syntax

Parameter Set: Get0
Get-DhcpServerv4OptionValue [[-OptionId] <UInt32[]> ] [[-ScopeId] <IPAddress> ] [-All] [-AsJob] [-Brief] [-CimSession <CimSession[]> ] [-ComputerName <String> ] [-PolicyName <String> ] [-ReservedIP <IPAddress> ] [-ThrottleLimit <Int32> ] [-UserClass <String> ] [-VendorClass <String> ] [ <CommonParameters>]

Detailed Description

The Get-DhcpServerv4OptionValue cmdlet returns the IPv4 option values for one or more IPv4 options at the server, scope or reservation level. Use the VendorClass and UserClass parameters to get option values for a specific vendor class or for a specific user class. If the OptionId parameter is not specified, then this cmdlet returns the option values for all the options configured at the specified level either the server, the scope, or the reservation level.

If only the ReservedIP parameter is specified, then the option values set at the rReservation level are returned. If only the ScopeId parameter is specified, then the option values set at the scope level are returned. If neither the ScopeId nor the ReservedIP parameter are specified, then option values set at the server level are returned. The ScopeId and ReservedIP parameters cannot both be specified.

If neither the VendorClass nor UserClass parameter is specified, then this cmdlet gets the standard option values set.

The PolicyName and UserClass parameters cannot both be specified.

The PolicyName parameter cannot be specified if the ReservedIP parameter is specified.

Note: The option values for policies only exist for DHCP server services running on Windows Server® 2012. For older versions, only user class based option values exist.

To get legacy user class options, the UserClass parameter must be specified.

Parameters

-All

Gets the option values for a scope, server, or reservation. Option values can include vendor class, user class, and policy specific.
If only this parameter is specified, then this cmdlet will get all of the option values for a scope, server, or reservation.
If the OptionId parameter and this parameter are specified, then option values for the specified option identifier (ID) for all of the vendor classes, user classes and policies will be returned.
If the VendorClass parameter and this parameter are specified, then all of the option values for the specified vendor class including those for any user class or policy would be returned.
If the UserClass parameter and this parameter are specified, then all of the option values for the specified user class including any vendor specific options would be returned.
If the PolicyName parameter and this parameter are specified, then all of the option values for the specified policy including any vendor specific options would be returned.

-AsJob

-Brief

Specifies that the name of the option is not returned in the option value object. This parameter improves the performance of this cmdlet by not requesting the name of the option from the DHCP server service. For repeatedly fetching a large number of option values with this cmdlet use of the Brief parameter is recommended.

-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 IDs of the options being requested.

-PolicyName<String>

Specifies the name of the policy for which one or more option values are requested.

-ReservedIP<IPAddress>

Specifies the IPv4 address of the reservation for which the option values are requested.

-ScopeId<IPAddress>

Specifies the ID of the scope, in IP address format, for which one or more option values are requested.

-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.

-UserClass<String>

Gets the option values for that user class.

-VendorClass<String>

Gets the option values for that 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).

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

• Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DHCP/DhcpServerv4OptionDefinition

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

• Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DHCP/DhcpServerv4Policy

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

• Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DHCP/DhcpServerv4Reservation

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

• Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DHCP/DhcpServerv4Scope

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

Outputs

The output type is the type of the objects that the cmdlet emits.

• Microsoft.Management.Infrastructure.CimInstanceroot/Microsoft/Windows/DHCP/DhcpServerv4OptionValue[]

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.
