Assigning and viewing NSX Security tags via PowerShell / PowerNSX

I have a bunch of VM names in a text file. I want to assign an NSX Security tag to all of them.

Get-Content .\InternetVMs.txt | %{ Get-VM $_ | New-NsxSecurityTagAssignment -ApplyTag -SecurityTag (Get-NsxSecurityTag internet_access) }

1	Get-Content .\InternetVMs.txt \| %{ Get-VM $_ \| New-NsxSecurityTagAssignment -ApplyTag -SecurityTag (Get-NsxSecurityTag internet_access) }

To get the NSX Security tags of a bunch of VMs in a text file (so u can confirm the above worked):

Get-Content .\InternetVMs.txt | %{ Get-VM $_ | Get-NsxSecurityTagAssignment  | select-object @{Name="SecurityTag"; expression = {$_.securitytag.name}}, VirtualMachine }

1	Get-Content .\InternetVMs.txt \| %{ Get-VM $_ \| Get-NsxSecurityTagAssignment \| select-object @{Name="SecurityTag"; expression = {$_.securitytag.name}}, VirtualMachine }

These require PowerNSX BTW.

I had to do the same for a bunch of VMs in a folder too:

Get-Folder "XenDesktops" | Get-VM | %{ $_ | New-NsxSecurityTagAssignment -ApplyTag -SecurityTag (Get-NsxSecurityTag internet_access) }

1	Get-Folder "XenDesktops" \| Get-VM \| %{ $_ \| New-NsxSecurityTagAssignment -ApplyTag -SecurityTag (Get-NsxSecurityTag internet_access) }

Lastly, to find all VMs assigned a security tag:

Get-NsxSecurityTagAssignment -SecurityTag (Get-NsxSecurityTag internet_access)

1	Get-NsxSecurityTagAssignment -SecurityTag (Get-NsxSecurityTag internet_access)
