I'm trying to change the ForgedTransmits for VDPortgroup without success

PowerCLI C:\> Get-VDPortgroup | ?{$_.IsUplink -eq $true} | Get-VDSecurityPolicy

VDPortgroup                    AllowPromiscuous MacChanges ForgedTransmits

-----------                    ---------------- ---------- ---------------

AFA_vds-DVUplinks              False            False      True

PowerCLI C:\> Get-VDPortgroup | ?{$_.IsUplink -eq $true} | Get-VDSecurityPolicy | Set-VDSecurityPolicy -ForgedTransmits $false

From the error message it looks as if the communication with one ESXi node (lab.domaine.intrne) is not working.

it's strange behaviour, as the lockdown Mode is disabled and not sure where I need to check to troubleshoot this issue

Can you try a Disconnect-Connect for the problematic ESXi node?
