Get-VMHost | Sort -Property Name | %{Get-View $_.ID} | %{$esxname = $_.Name; Get-View $_.ConfigManager.NetworkSystem} | %{
  foreach($physnic in $_.NetworkInfo.Pnic){
    $pnicInfo = $_.QueryNetworkHint($physnic.Device)
    foreach($hint in $pnicInfo){
      Write-Host $esxname $physnic.Device $hint.connectedSwitchPort.DevId $hint.connectedSwitchPort.PortId
    }
  }
}

Example output:

esxserver01 vmnic1 core-switch-01 GigabitEthernet1/0/1
esxserver02 vmnic2 core-switch-02 GigabitEthernet1/0/2
esxserver03 vmnic3 core-switch-01 GigabitEthernet1/0/2
esxserver04 vmnic4 core-switch-02 GigabitEthernet1/0/1
