Get-DhcpServerv4OptionValue

Last Updated: 3/27/2017

SYNOPSIS

Returns the IPv4 option values for IPv4 options at the server, scope, or reservation level.

SYNTAX

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

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 you do not specify the OptionId parameter, 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 you specify only the ReservedIP parameter, the option values set at the rReservation level are returned. If you specify only the ScopeId parameter, the option values set at the scope level are returned. If you specify neither the ScopeId nor the ReservedIP parameter, option values set at the server level are returned.

If you specify neither the VendorClass nor UserClass parameter, 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.

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

To get legacy user class options, you must specify the UserClass parameter.

EXAMPLES

Example 1: Get standard option values at the server level

PS C:\> Get-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com"

This example gets all the standard DHCPv4 option values, or non-class specific, configured at the server level.

Example 2: Get standard option values for a scope

PS C:\> Get-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0

This example gets all the standard DHCPv4 option values, or non-class specific, configured for the specified scope.

Example 3: Get standard options values for a reservation

PS C:\> Get-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -ReservedIP 10.10.10.5

This example gets all of the standard DHCPv4 option values, or non-class specific, configured for the specified reservation.

Example 4: Get verdor class specific option values for a vendor class

PS C:\> Get-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0 -VendorClass MSUCClient

This example gets all of the vendor class specific DHCPv4 option values configured on the specified scope for the specified vendor class.

Example 5: Get an option value for a scope by using option ID

PS C:\> Get-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0 -OptionId 23

This example gets the DHCPv4 option value configured on the specified scope for the specified option ID.

Example 6: Get all option values for a scope

PS C:\> Get-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0 -All

This example gets all of the DHCPv4 option values, including standard as well as vendor class or user class specific, configured on the specified scope.

Example 7: Get standard option values for a scope in brief

PS C:\> Get-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0 -Brief

This example gets all of the standard DHCPv4 option values configured on the specified scope. The object that is returned does not contain the name of the option. The Brief parameter increase the performance by removing the delay required to get the name of the option from the DHCP server service.

Example 8: Get user specific option values for a user class

PS C:\> Get-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0 -UserClass "LabComputer"

This example gets all of the user class specific DHCPv4 option values configured on the specified scope for the specified user class.

Example 9: Get standard option values for a policy

PS C:\> Get-DhcpServerv4OptionValue -ComputerName dhcpserver.contoso.com -ScopeId 10.10.10.0 -Policy SmartPhonePolicy

This example gets all of the standard DHCPv4 option values configured on the specified scope for the specified policy.

Example 10: Get option values for a policy and vendor class

PS C:\> Get-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0 -Policy "SmartPhonePolicy" -VendorClass "HTC Phone"

This example gets all of the standard, or non-class specific, DHCPv4 option values configured on the specified scope for the specified policy and vendor class.

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, this cmdlet gets all of the option values for a scope, server, or reservation. If the OptionId parameter and this parameter are specified, option values for the specified option identifier (ID) for all of the vendor classes, user classes and policies is returned. If the VendorClass parameter and this parameter are specified, all of the option values for the specified vendor class including those for any user class or policy is returned. If the UserClass parameter and this parameter are specified, all of the option values for the specified user class including any vendor specific options is returned. If the PolicyName parameter and this parameter are specified, all of the option values for the specified policy including any vendor specific options is returned.

-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.

-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 by using this cmdlet, we recommend use of the Brief parameter.
