N1K or DVS info on a ESXi Host

[Compton94]

We are trying to find a way to see if an ESXi host is on a N1K or standard switch as we are moving all systems to N1K and need to verify it was completed.  We thought of using the Get-CDP but since we are using Cisco UCS blades it always comes back Cisco Nexus.  Does anyone have any thoughts on how this can be done?

thanks in advance.

We're also having a problem accomplishing the same task when trying to get information about an n1k on a specific node.  Trying the other tricks around the Internet don't seem to work when trying to poll data from a specific node, but rather only at the VC level.

Get-VDSwitch -VMHost myhost.example.com

Get-VDSwitch  Unable to cast object of type 'VMware.Vim.DistributedVirtualSwitch' to type 'VMware.Vim.VmwareDistributedVirtualSwitch'.

At line:1 char:13

+ Get-VDSwitch <<<<  -VMHost myhost.example.com

    + CategoryInfo          : NotSpecified: (:) [Get-VDSwitch], VimException

Isn't that to be expected, since dvSwitch is a vCenter feature ?

[jason89s]

The intention is to put it in a try/catch to see if an ESXi node is joined to an n1k along the lines of what Compton94 is trying to do.  Do you have a suggestion for how to check if an ESXi server is joined to an n1k?

I don't have a N1K handy right now, but does this list the connected ESXi hosts per N1K ?

foreach($dvs in Get-VDSwitch){
  Get-View -Id ($dvs.ExtensionData.Config.Host | %{
    $_.Config.Host}) | 
  Select @{N="dvSw";E={$dvs.Name}},@{N="ESX";E={$_.Name}}

}

This looks like its going to work great, thanks LucD!

Nice one LucD!  I tested this on a wide variety of 1000v deployments (vCenter 5.0 and 5.1, and ESXi hosts at 4.1 and 5.1).  Works perfectly.

Thanks for the feedback.
