Hello André and Ethan,
Thank you for your answer.
As i said before, Virtual machines on a same VSwitch can not communicate with each other --> Why ??
But they can communicate with physical or virtual machines (on another ESX) connected to the same network.
Here is a printscreen of my network configuration on the problematic ESXi.
Image may be NSFW.
Clik here to view.
André,
The configuration fo port on my physical switch impacts the communication between virtual machines ?
nothing configured on physical switches
what can be policies ?
Ethan,
My VSwitches are configured for VMwares.
