The Get-CimAssociatedClass command replaces the use of the ASSOCIATORS OF query type when using the CIM cmdlets.

The following command gets the class instances associated with Win32_NetworkAdapterConfiguration. As the arguments for the Get-CimInstance command are long strings, splatting is used to pass the parameters into the command:

$params = @{ 
    ClassName = 'Win32_NetworkAdapterConfiguration' 
    Filter    = 'IPEnabled=TRUE AND DHCPEnabled=TRUE' 
} 
Get-CimInstance @params | Get-CimAssociatedInstance  

The following example uses Get-CimAssociatedClass to get the physical interface associated with the IP configuration:

$params = @{ 
    ClassName = 'Win32_NetworkAdapterConfiguration' 
    Filter    = 'IPEnabled=TRUE AND DHCPEnabled=TRUE' 
} 
Get-CimInstance @params | ForEach-Object { 
    $adapter = $_ | Get-CimAssociatedInstance -ResultClassName Win32_NetworkAdapter 
 
    [PSCustomObject]@{ 
        NetConnectionID = $adapter.NetConnectionID 
        Speed           = [Math]::Round($adapter.Speed / 1MB, 2) 
        IPAddress       = $_.IPAddress 
        IPSubnet        = $_.IPSubnet 
        Index           = $_.Index 
        Gateway         = $_.DefaultIPGateway 
    } 
}
