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.

Examples

EXAMPLE 1

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

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

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

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

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

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

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

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.

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

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.

Optional 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.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False

-Brief

Specifies that the name of the option is not returned in the option value object.

-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-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227967 or Get-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227966 cmdlet. The default is the current session on the local computer.
