Configure and monitor Windows 2012 DHCP server with Powershell

  • 772

We've recently been working with the documentation here to set up some access policies for a new DHCP server.

I've been able to successfully import 600+ records with the Set-DhcpServerv4Policy -Name -ScopeID command.

This seems to have wiped out the 2 records that were already in there, which leads to where I am running into issue.

I am trying to search the list that is now there to see if those MACs were included using Get-DhcpServerv4Policy -Name "Allow Private" -ScopeId 192.168.16.0 but all I get is an condensed response of the MAC's.

Name : Allow Private Description : Allow access to Private Wireless Network Enabled : False ScopeId : 192.168.16.0 ProcessingOrder : 2 Condition : OR VendorClass : UserClass : MacAddress : {EQ, 00-06-5b-22-xx-xx, 00-08-ca-e7-xx-xx, 00-0e-35-de-e5-xx...}e

I've added the -fl switch and get the same results.

Windows Server 2008 R2 had an export feature but I don't see it here in Windows Server 2012.

If the MAC's aren't in the list I need to add them - and am hoping not to keep the list I have and just add them to it - but if I have to do that I will, unless there is an update command that I am missing.

Thanks for any thoughts.

    If you just want to expand the MacAddress collection you can do something like the following.

     Get-DhcpServerv4Policy -Name "Allow Private" -ScopeId 192.168.16.0 |
     Select-Object -ExpandProperty MacAddress

    I've also seen shorthand examples for expanding collections.

    (Get-DhcpServerv4Policy -Name "Allow Private" -ScopeId 192.168.16.0).MacAddress
