Is it possible to use Orion.UDT.Port AdministrativeShutdown?

I'm a little new to the SDK, and with the new Shutdown and Enable buttons in the web console of UDT, I was trying to us PoSH to shut down an interface.

The meat and potatoes of the script looks like this:

$nodeid = 137

$port = 1169

Invoke-SwisVerb $swis Orion.UDT.Port AdministrativeShutdown @("N:$node","UP:$port")

Is it possible to use the SDK for this action? How far off am I?

I've tried a couple methods that seem like they should work, but I'm stuck at this... This is the error I'm getting now:

Invoke-SwisVerb : Verb Orion.UDT.Port.AdministrativeShutdown: Cannot find assembly

At C:\Users\alagrone\Desktop\Basic AdShut.ps1:15 char:16

+ Invoke-SwisVerb <<<<  $swis Orion.UDT.Port AdministrativeShutdown @("N:$node","UP:$port")

    + CategoryInfo          : InvalidOperation: (:) [Invoke-SwisVerb], FaultException`1

    + FullyQualifiedErrorId : SwisError,SwisPowerShell.InvokeSwisVerb

or, with this modification:

if (! (Get-PSSnapin | where {$_.Name -eq "SwisSnapin"})) {

    Add-PSSnapin "SwisSnapin"

}

#Connect to Swis

#$hostname = "localhost"

#$cred = New-Object -typename System.Management.Automation.PSCredential -argumentlist $username, $password

$swis = Connect-Swis -v2 -Trusted #-Hostname 'localhost'

#$nodeid = 137

$portids = 1169

#Get-SwisData $swis "SELECT NodeID FROM Orion.UDT.Port WHERE PortID=@portids" @{portids=$portids}

#Get-SwisData $swis "SELECT PortID FROM Orion.UDT.Port WHERE PortID=@portids" @{portids=$portids}

$node= Get-SwisData $swis "SELECT NodeID FROM Orion.UDT.Port WHERE PortID=@portids" @{portids=$portids}

$port= Get-SwisData $swis "SELECT PortID FROM Orion.UDT.Port WHERE PortID=@portids" @{portids=$portids}

Invoke-SwisVerb $swis Orion.UDT.Port AdministrativeShutdown @("$node","$port")

I get:
