   [-List] <String>
   [-MacAddress] <String[]>
   [-AsJob]
   [-CimSession <CimSession[]>]
   [-ComputerName <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

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

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

Example 2

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

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 named MacAddressFilters.csv to the allow MAC address list of the DHCP server service running on the computer named dhcpserver.contoso.com. The Import-Csvhttp://go.microsoft.com/fwlink/p/?LinkID=113341 cmdlet returns the objects with Mac address filter fields that are piped to this cmdlet, which in turn adds the MAC address filters to the server. The file 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
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[]
Position:2
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False

Optional Parameters

-AsJob

ps_cimcommon_asjob

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-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.

Type:CimSession[]
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 running the DHCP server service.

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

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
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, then 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 needs to be added to the other list, such as the deny list.

If this parameter is not specified, then the cmdlet will fail 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
Position:Named
Default value:False
Accept pipeline input:False
Accept wildcard characters:False
