Hello,
Is it possible to allow promiscuous mode for specific VMs and not all machines?
Thank you.
create a different portgroup for those VMs?
With a vSphere Standard switch the most granular level for the PM policy is the Port Group, so you create a Port Group just for that VM to use.
vSphere Distributed switches have the ability for overrides of the Port Group policy to be set at the Port level, so once your VM is connected to a specific Port you could edit the Port and set an override (or stick with the dedicated Port Group as above)
