I have the following code which takes a DVSwitch and deduces which port is the active uplink port. As-is, the code reports the correct information as shown here:

Without copying the whole script here, I'll break it down into key components so you can see what I've done:
Function GetDVSwitchDetails
{
param(
[Object]$ESXiHost,
[Object]$oSwitchObject
)
$section1Stopwatch = [System.Diagnostics.Stopwatch]::StartNew()
# Retrieve vCenter Name.
$vCenterName = $oSwitchObject.ExtensionData.Client.ServiceUrl.Split('/')[2]
# Get all port groups on this host on this switch.
$PG = get-virtualportgroup -VMHost $esxihost -VirtualSwitch $oSwitchObjects -Distributed
# Get all switch ports for this switch.
$AllSwitchPorts = Get-VDPort -VDSwitch $oSwitchObject.name
$tmpAllPortGroups = @()
ForEach ($ESXiPG in $PG)
{
$section11Stopwatch = [System.Diagnostics.Stopwatch]::StartNew()
$Item = New-Object PSObject
# VLANID can be a single value or an object with 2 properties: Start & End.
# Need to combine both values, when they show up, into one value.
$vLANID = $ESXiPG.extensionData.Config.DefaultPortConfig.VLAN.VLANID
If ([String]::IsNullOrEmpty($vLANID.Start)) { $vLANID_All = $vLANID }
Else
{ $vLANID_All = $(@($vLANID.Start, $vLANID.End) -join "-" ) }
# Get all Active uplinks for this port group.
$ActiveUplinkPorts = $ESXiPG.extensionData.Config.DefaultPortConfig.UplinkTeamingPolicy.UplinkPortOrder.ActiveUplinkPort
$vLANActiveUplinkPortNames = @()
# Get vmnic name from dvUplink##.
ForEach ($ActiveUplinkPort in $ActiveUplinkPorts)
{
# Search all switch ports on the selected switch where the host is the same as the current host and the uplink name is the same as the current uplink name.
$section111Stopwatch = [System.Diagnostics.Stopwatch]::StartNew()
$ActiveUplinkPortVMNIC = ($AllSwitchPorts | Where-object {$_.ProxyHost.Name -eq $esxihost -and $_.name -eq $ActiveUplinkPort}).ConnectedEntity
$vLANActiveUplinkPortNames += "$ActiveUplinkPort ($($ActiveUplinkPortVMNIC.Name))"
$section1Stopwatch.Stop()
Write-Host "[ForEach (`$ActiveUplinkPort in `$ActiveUplinkPorts)] took $($section1Stopwatch.Elapsed.TotalSeconds) seconds to execute." -BackgroundColor DarkMagenta -ForegroundColor Magenta
}
# =========================================================================
$AllPortGroups = @()
# Cycle thru all hosts in the vCenter.
foreach($esx in Get-VMHost)
{
Write-Host "Host Name: $($esx.name):"
# Get all Standard switches connected to this host.
$oSwitchObjects = Get-VirtualSwitch -VMHost $esx -Standard
# Cycle thru each Standard switch and return the connected port groups.
ForEach($oSwitchObject in $oSwitchObjects)
{
Write-Host "Switch: $($oSwitchObject.Name):"
$AllPortGroups += GetSTDSwitchDetails -ESXiHost $esx -oSwitchObject $oSwitchObject
}
# Get all Distributed switches connected to this host.
$oSwitchObjects = Get-VirtualSwitch -VMHost $esx -Distributed
# Cycle thru each Distributed switch and return the connected port groups.
ForEach($oSwitchObject in $oSwitchObjects)
{
Write-Host "Switch: $($oSwitchObject.Name):"
$AllPortGroups += GetDVSwitchDetails -ESXiHost $esx -oSwitchObject $oSwitchObject
}
}
The line of code which takes around 50 seconds to execute (actually on the vCenter used above, it took around 453s) each time is this one:
$ActiveUplinkPortVMNIC = ($AllSwitchPorts | Where-object {$_.ProxyHost.Name -eq $esxihost -and $_.name -eq $ActiveUplinkPort}).ConnectedEntity
The variable "$AllSwitchPorts" contains 782 records looking like the following (rows have been culled and values have been changed):

For this particular host, the result should be:
$vLANActiveUplinkPortNames
dvUplink2 (vmnic7)
Please let me know what I should do.
Thanks.
PS: Special shout-out to LucD who helped me develop the code for this.
