Question

I have NLB installed and set up. I get the interface data like so:

Get-NlbClusterNodeNetworkInterface



InterfaceName       : quanet
   NlbBound            : False
   Cluster             :
   DhcpEnabled         : False
   InterfaceIP         : 10.165.250.206
   InterfaceSubnetMask : 255.255.0.0
   ClusterPrimaryIP    :
   ClusterSubnetMask   :

   InterfaceName       : cluster
   NlbBound            : False
   Cluster             :
   DhcpEnabled         : False
   InterfaceIP         : 172.16.1.206
   InterfaceSubnetMask : 255.255.255.0
   ClusterPrimaryIP    :
   ClusterSubnetMask   :

I would like to use Powershell to set NlbBound to true. Needless to say setting the property doesn’t work. e.g

   $x = Get-NlbClusterNodeNetworkInterface
   $x[1].nlbbound = $true
   $x = Get-NlbClusterNodeNetworkInterface
   echo $x[1].NlbBound
   False

I want to avoid having to explicitly set the property in the Network adaptor settings because this functionality will live in a script.
I’d also like to avoid using WMI if possible.

According to the Get-Member cmdlet the NlbBound property is setible:

Get-Member -InputObject $x[1]

   TypeName: Microsoft.NetworkLoadBalancingClusters.PowerShell.NetworkInterface

InterfaceName       Property   System.String InterfaceName {get;set;}
InterfaceSubnetMask Property   System.String InterfaceSubnetMask {get;set;}
NlbBound            Property   **System.Boolean NlbBound {get;set;}**
