[<CommonParameters>] Description
The Set-DhcpServerv4Policy cmdlet sets the properties of an existing policy either at the server level or at the specified scope level. If the CircuitId, ClientId, Fqdn, MACAddress, RelayAgent, RemoteId, SubscriberId, UserClass, or VendorClass parameter is specified, the conditions of the policy are being changed and this cmdlet behaves as follows:
If the VendorClass parameter is specified and the policy being modified already has conditions for the VendorClass parameter value, the existing VendorClass parameter value is removed and the new VendorClass parameter value is added.
However, if the policy being modified has conditions for the MacAddress parameter value, the MacAddress parameter value is not changed and is logically combined (ORꞌd) or differenced (ANDꞌd) with the VendorClass-based conditions.
The same applies to any of the CircuitId, ClientId, Fqdn, MACAddress, RelayAgent, RemoteId, SubscriberId, UserClass, or VendorClass parameters that are used in the conditions.
Examples
Example 1: Modify a server level policy
PS C:\> Set-DhcpServerv4Policy -ComputerName "dhcpserver.contoso.com" -Name "DevicesPolicy" -NewName TabletPolicy -Description "policy for tablet devices" -ProcessingOrder 4 -Enabled $FalseThis example renames the server level policy named DevicesPolicy to TabletPolicy, sets a description string, disables the policy, and sets the processing order to 4.
Example 2: Modify the conditions of the server level policy
PS C:\> Set-DhcpServerv4Policy -Name "PhysicalMachinesPolicy" -Condition OR -MacAddress NE,00155D*,000569*This example modifies the conditions of the server level policy for non-Hyper-V clients. If the policy had an existing MAC address based condition, the same condition is replaced with the condition specified in this cmdlet. However, if the policy had conditions based on other fields, such as the VendorClass, UserClass, ClientId, or RelayAgent parameters, those is retained and logically combined (ORꞌd) with the newly added MAC address based condition.
Example 3: Modify the conditions of the server level policy for non-Hyper-V clients
PS C:\> Set-DhcpServerv4Policy -Name "PhysicalMachinesPolicy" -Condition OR -MacAddress NE,00155D*,000569* -VendorClass ""This example modifies the conditions of the server level policy for non-Hyper-V clients. If the policy had an existing MAC address based condition, a vendor class based policy, or both, the conditions are replaced with the condition specified in this cmdlet.
Example 4: Sets lease duration for a server level policy
PS C:\> Set-DhcpServerv4Policy -Name "TabletPolicy" -ComputerName "dhcpserver.contoso.com" -LeaseDuration 10This example sets the lease duration for the server level policy named TabletPolicy to 10 days for the specified computer.
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.
