   [-Description <String>]
   [-MacAddress] <String[]>
   [-List] <String>

Description

The Add-DhcpServerv4Filter cmdlet adds the specified MAC address filter to the Dynamic Host Configuration Protocol (DHCP) server service. The MAC address can be added to the allow list or the deny list.

Examples

Example 1: Add a client to the allowed filter

PS C:\> Add-DhcpServerv4Filter -List Allow -MacAddress "F0-DE-F1-7A-00-5E" -Description "Laptop 09"

This example adds the specified client identified by the MAC address to the allowed list of MAC address filters.

Example 2: Add multiple clients to the allowed filter

PS C:\> Add-DhcpServerv4Filter -List Allow -MacAddress "F0-DE-F1-7A-00-5E", "F0-DE-F1-7A-00-5C"

This example adds the specified clients identified by their MAC address to the allowed list of MAC address filters.

Example 3: Add address filters from a file

PS C:\> Import-Csv -Path "MacAddressFilters.csv" | Add-DhcpServerv4Filter -ComputerName "dhcpserver.contoso.com" -List Allow

This example adds all of the MAC address filters in the file that is named MacAddressFilters.csv to the allow MAC address list of the DHCP server service running on the computer named dhcpserver.contoso.com. The Import-Csv cmdlet returns the objects that have Mac address filter fields that are piped to this cmdlet, which in turn adds the MAC address filters to the server. The file that is named MacAddressFilters.csv should be in the following comma-separated values (CSV) format:

MacAddress,Description

1a-1b-1c-1d-1e-1f,Computer1

2a-2b-2c-2d-2e-2f,Computer2

3a-3b-3c-3d-3e-3f,Computer3

Required Parameters

-List

Specifies the list to which one or more MAC addresses are to be added. The acceptable values for this parameter are: Allow or Deny.

Type:String
Parameter Sets:Allow, Deny
Position:1
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-MacAddress

Specifies one or more MAC addresses which are to be added to the MAC address filter list.

Type:String[]
Aliases:ClientId
Position:2
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False

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 DHCP server service.

Type:String
Aliases:Cn
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:False
Accept pipeline input:False
Accept wildcard characters:False
-Description

Specifies the description string for the MAC address filter being added.

Type:String
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-Force

Specifies that, if one or more of the MAC addresses are already present in the allow or deny list, the matching MAC addresses are deleted and the new entries created.

This parameter is useful in the case where the MAC address specified is already present in one list, such as the allow list, and the same MAC address now has to be added to the other list, such as the deny list.

If this parameter is not specified, the cmdlet fails if the specified MAC address is already present in any of the lists.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-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
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:SwitchParameter
Aliases:wi
Position:Named
Default value:False
Accept pipeline input:False
Accept wildcard characters:False
