How to Set CDP on a vSwitch–the #PowerCLI Way

We all know that you get CDP information in a number of ways (also PowerCLI), KB 1007069 provides a number of ways to do it.

But how would you go about setting CDP on the vSwitch?

That can be done on the host itself in a number of ways:

esxcfg-vswitch –B both vSwitch0

but also with esxcli

esxcli network switch standard set –c both –v vSwitch0

That got me thinking…. esxcli… where had I used that before – of course Netstat for ESXi.

So why not try and do the same here?

The quick and dirty way (I will update later with a proper function)

$esxcli = Get-EsxCli -VMHost $myhost

Why all 3 Parameters and where did they come from?

$esxcli.network.vswitch.standard | gm

The set method is described as follows:

Name          MemberType    Definition
set              CodeMethod   boolean set(string cdpstatus, long mtu, string vswitchname)

And where do get the values that are valid for “cdpstatus” ? esxcli of course

# esxcli network vswitch standard set

Error: Missing required parameter -v|--vswitch-name

Usage: esxcli network vswitch standard set [cmd options]

  set                   This command sets the MTU size and CDP status of a given virtual switch.

Cmd options:
  -c|--cdp-status=<str> The CDP status of the given virtual switch. It can be 'down', 'listen', 'advertise' or 'both'
  -m|--mtu=<long>       The MTU size of the given virtual switch.
                        The name of virtual switch to apply the configurations. (required)

Update: March 06, 2012

I promised to update with a proper function on how to do this, and here it is:

Function Set-VirtualSwitchCDP {


                  Set the CDP setting on a Standard Virtual Switch.
                  Using the Get-Esxcli cmdlet you can changed the CDP Settings 
                  on virtual switch on an ESX host.
            .NOTES Author: Maish Saidel-Keesing
            .PARAMETER  VMHost
                  ESX server to perform the function.
            .PARAMETER  MTU
                  The MTU settings of the vSwitch, default is 1500.Valid values are 
                  between 1500-9000
            .PARAMETER  CDP
                  The CDP setting for the vSwitch. 
                  Valid values are 'down', 'listen', 'advertise' or 'both'.
            .PARAMETER  vSwitch
                  The Name of the Standard vSwitch on which to perform the action.
                  PS C:\> Set-VirtualSwitchCDP -VMhost esx1 -MTU 1500 -CDP both -vSwitch vSwitch0
                  PS C:\> Get-VMhost Myhost | Set-VirtualSwitchCDP -vSwitch vSwitch0


    $MTU = 1500,

    $CDP = "both",



       if ($pscmdlet.ShouldProcess($VMHOST,"Updating $vSwitch with MTU $MTU and CDP setting of $CDP"))      {
                  foreach ($hostobject in (Get-VMHost $VMHost)) {
                        $esxcli = Get-EsxCli -VMHost $hostobject


Windows 8 Developer Preview on ESXi5

Thank you William Lam @lamw!!!!!!!

Due to William's How to Run Windows 8 on vSphere 5 (for reals) post I can now try out
Windows 8 Developer Preview on my ESX boxes.

This was resolved in patch ESXi500-201112001 - it just seems that no-one told us until now.. It would be very interesting to hear what actually changed in this patch.

Running on Workstation was not a good option for me. My lab is on ESX boxes.

But now I am happy - and I can start to finally get to know the new OS.

Windows 8


My Wish for dvFabric – a dvSwitch for Storage

This one has been sitting with me for a while. It would be nice to hear your comments on this.

The dvSwitch (Distributed Virtual Switch) – oh how it has changed our lives…

Do you all remember the days when you had to manually add the all the portgroups and network settings to a new host? We use scripts, we use mega-kickstart deployment scripts, gui applications.  Let us not forget that it is still the case for all those who do not have and Enterprise Plus vSphere license. You do have to pay some extra for the “premium features”, and if you ask me – it not really a premium feature but more of a necessity.

But since I have gotten used to a dvSwitch – those things are all in the past. Network configuration of a host – is really as simple as adding click click click (yes…. I know…. you could also automate it as well….), and I do not have to worry about configuration issues any more. This vmnic is used for vMotion, this one for FT, this for NFS/iSCSI – it is all so simple.

I think it is time that we asked for the next stage. It is time for a revolution!!

Maybe we should call it dvFabric?

Let me explain what I would like to see.

Today when you set up a host you have to setup your NFS/iSCSI/SAN connection more or less manually. Before you say – hey what about Host Profiles – yes you could do that with host profiles – but the way that I see this is – Host Pofiles comes as a band-aid to this issue – not solution to the problem. By applying a profile to a host – you are are running a process that runs a set of actions to set a configuration. You could so the same with a set of scripts (PowerCLI or Perl) but this is packaged very well in vCenter and easy to use.

So how do I envision this dvFabric? Essentially the same as a dvSwitch. A logical entity to which I attach my network cards (for iSCSI/NFS) or my HBA’s (for FcoE or FC). I define which uplink goes to which storage, what the multi-pathing policy is for this uplink, how many ports should be used, what is the failover policy for which NIC, which NFS volumes to mount, which LUNS to add – I gather you see what I am getting at. Here is a diagram trying to visualize this.


Once the dvFabric has been configured correctly – all you would need to do is add in a Host and all the storage will be configured automagically.

Today there are a number of additional benefits available with using a dvSwitch – just to name a few – port mirroring, Netflow, PVLANs, NIOC.

I am sure that there are additional benefits that VMware could come up with – have a distributed virtual Fabric switch. One that just came to me is to perform the zoning in the dvFabric itself – and not to each and every host. This way the storage administrator would only have to zone one entity and the rest will be up to the VI Admin. The same regarding NFS exports.

Will this ever come about? Who knows? It does seem to be to be the another natural stage in the abstraction of the layers which has been the trend of the last few years.

I guess one of the questions we should ask ourselves – and the storage vendors, Are we (and they) ready for it? Is this something that could / should / would happen in the future.

What are the risks? What are the benefits?

Perhaps some brilliant minds in some strange place in Palo Alto are, already thinking about this….?

I would appreciate your comments and thoughts.
