Is this possible? I've tried multiple combinations of Get-UcsFabricNetGroup & Get-UcsVnicTemplate and cannot seem to get this to work.
Both UCS commands produce results, I just can't figger out how to get the parent of a specific UCS Fabric Net Group.
I'm sure it's very simple to do?

Will this do what you are looking for?
$vnicTemplates = Get-UcsVnicTemplate
foreach($vnicTemplate in $vnicTemplates)
{
Write-Host vNIC Template $vnicTemplate.Name -ForegroundColor yellow
$vlanGroups = Get-UcsManagedObject -Dn $vnicTemplate.Dn -Hierarchy
foreach($vlanGroup in $vlanGroups)
{
if($vlanGroup.OperName -like "fabric/lan/net-group*")
{
Write-Host `t Vlan Group: $vlanGroup.Name -ForegroundColor white
}
}
}
Output:

Ahhhh, so unlike other systems such as vSphere, related items in UCSM are not connected to each other in any way. So it seems from your example, the only way to associate some objects to their parent object, such as vLAN Groups to vNIC Templates, is to use the DN properties of each item to ensure they are matching. VERY NICE!
Based on your fix, I've turned your humble code into a beast of an animal, one which can do the following:
You can perform the following actions:
* List ALL vNIC Templates, associated vLAN Groups and respective vLANs.
* List respective vNIC Templates, associated vLAN Groups and respective vLANs using the name of a vNIC Template.
* List ALL vNIC Templates, associated vLAN Groups and respective vLANs using the name of a vLAN Group.
* List ALL vNIC Templates, associated vLAN Groups and respective vLANs using the name of a vLAN.
* List ALL vNIC Templates, associated vLAN Groups and respective vLANs using the ID of a vLAN.
The parameters can accept the wildcard character "*" to find multiple instances.
And it works really well! I spent a lot of time on this one, and it although I'm a novice PowerShell programmer and even more novice UCSM users, I think it rocks. I would love to see what people think of it and if it can be improved.
Thanks again.

.SYNOPSIS
UCS Manager does not give the ability to track the relationship between vLAN Groups and vNIC Templates. This script will thus extract information from the connected UCS Manager regarding vNIC Templates, vLAN Groups and vLANs.
This script only works with vLANs which are present in vLAN Groups.
Version: 1.5
Written by: Julian Milano
Date Created: 18th Aug 2023
.Description
The script gathers all vNIC Templates and checks for associated vLAN Groups. Where a vLAN Group is found, the vLANs within that vLAN Group are extracted.
You can perform the following actions:
* List ALL vNIC Templates, associated vLAN Groups and respective vLANs.
* List respective vNIC Templates, associated vLAN Groups and respective vLANs using the name of a vNIC Template.
* List ALL vNIC Templates, associated vLAN Groups and respective vLANs using the name of a vLAN Group.
* List ALL vNIC Templates, associated vLAN Groups and respective vLANs using the name of a vLAN.
* List ALL vNIC Templates, associated vLAN Groups and respective vLANs using the ID of a vLAN.
The parameters can accept the wildcard character "*" to find multiple instances.
.PARAMETER vNICTemplateName
Optional. The name of the vNIC Template to interrogate.
.PARAMETER vLANGroupName
Optional. The name of the vLAN Group to interrogate.
.PARAMETER VLANName
Optional. The name of the vLAN to interrogate.
.PARAMETER vLANID
Optional. The ID of the vLAN to interrogate.
.PARAMETER ShowVLANs
Optional. By default, vLANs assocaited with vLAN Groups extracted from UCSM are not displayed.
This parameter will display the vLAN IDs and vLAN Names.
.PARAMETER ShowEmpty
Optional. By default, vNIC Templates with no associated vLAN Groups are not displayed.
This parameter will display the vNIC Template & DN.
.EXAMPLE
.\Get-UCScNICTemplate.ps1
Run the script on the currently connected UCS Manager displaying all vNIC Templates which have a vLAN Group associated.
The results show the vNIC Template name & vLAN Group Name.
------------------------------------------------------------------------------------------------------------------------------
.EXAMPLE
.\Get-UCScNICTemplate.ps1 -ShowVLANs
Run the script on the currently connected UCS Manager displaying all vNIC Templates which have a vLAN Group associated.
The results show the vNIC Template name, vLAN Group Name & vLANs in the respective vLAN Group.
------------------------------------------------------------------------------------------------------------------------------
.EXAMPLE
.\Get-UCScNICTemplate.ps1 -ShowEmpty
.EXAMPLE
Run the script on the currently connected UCS Manager displaying all vNIC Templates.
The results show the vNIC Template name and vLAN Group Name where one exists.
------------------------------------------------------------------------------------------------------------------------------
.EXAMPLE
.\Get-UCScNICTemplate.ps1 -vNICTemplateName "PFE-ESXI-A"
Run the script on the currently connected UCS Manager displaying the vNIC Template "PFE-ESXI-A".
The results show the vNIC Template name and vLAN Group Name where one exists.
------------------------------------------------------------------------------------------------------------------------------
.EXAMPLE
.\Get-UCScNICTemplate.ps1 -vLANGroupName "VGrp_TLS"
Run the script on the currently connected UCS Manager displaying all vNIC Templates which contain the vLAN Group "VGrp_TLS".
The results show the vNIC Template name and vLAN Group Name where one exists.
------------------------------------------------------------------------------------------------------------------------------
.EXAMPLE
.\Get-UCScNICTemplate.ps1 -VLANName "res_com_drtestprod_1902"
Run the script on the currently connected UCS Manager displaying all vNIC Templates which contain the vLAN name "res_com_drtestprod_1902".
The results show the vNIC Template name and vLAN Group Name where one exists.
------------------------------------------------------------------------------------------------------------------------------
.EXAMPLE
.\Get-UCScNICTemplate.ps1 -vLANID 1902
Run the script on the currently connected UCS Manager displaying all vNIC Templates which contain the vLAN ID "1902".
The results show the vNIC Template name and vLAN Group Name where one exists.
------------------------------------------------------------------------------------------------------------------------------
.EXAMPLE
.\Get-UCScNICTemplate.ps1 -VLANName "res_com_drtestprod_1902" -ShowVLANs
Run the script on the currently connected UCS Manager displaying all vNIC Templates which contain the vLAN Name "res_com_drtestprod_1902".
The results show the vNIC Template name, vLAN Group Name and all vLANs in the respective vLAN Group where one exists.
.INPUTS
None
.OUTPUTS
Results are exported to a CSV file in the same folder from which the script is run, with the following filenam convention:
"<UCS_Name>_vNICTemplate_Audit_<yyyy-MM-dd_HH_mm_ss>.csv"
