Within OSA, layer 2 and layer 3 can communicate (unlike HiperSockets) unless port isolation is turned on in the IP configuration. >What would be the impact if i start a z/os and a z/vm test environnement ? >Ethernet word will not be required ? The "ETHERNET" keyword tells the device driver to use "layer 2" protocol. That is, the driver will provide full ethernet frames, with MAC headers. Without ETHERNET, it defaults to "IP" which is also known as "layer 3", in which the driver provides only IP packets, not ethernet frames, and the OSA takes care of adding the MAC headers.
