Question

Checking NIC speed/duplex settings via command line

Asked by: kam_uk

Hi All

We are using HP PC's, running Windows XP OS's.

Normally, to check what the NIC's speed/duplex settings are, I would go to network properties, etc.

I was wondering if there was a way to check this via command line?

Thx

I have been in networking for more years then I care to admit to...  And I do not believe there is a way to do this via the command line...

There is a way to get the link speed using VBScript, but I can't find a WMI class that will give you the duplex status.
Here's a sample script that will output the speed of all your network adapters

On Error Resume Next

Const wbemFlagReturnImmediately = &h10
Const wbemFlagForwardOnly = &h20

arrComputers = Array("JOENEW")
For Each strComputer In arrComputers
   WScript.Echo
   WScript.Echo "=========================================="
   WScript.Echo "Computer: " & strComputer
   WScript.Echo "=========================================="

   Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\WMI")
   Set colItems = objWMIService.ExecQuery("SELECT * FROM MSNdis_LinkSpeed", "WQL", _
                                          wbemFlagReturnImmediately + wbemFlagForwardOnly)

   For Each objItem In colItems
      WScript.Echo "Active: " & objItem.Active
      WScript.Echo "InstanceName: " & objItem.InstanceName
      WScript.Echo "NdisLinkSpeed: " & objItem.NdisLinkSpeed
      WScript.Echo
   Next
