There is no ETHERNET option on the DEVICE statement, so you're probably getting configuration errors and the device isn't activating. Check the TCPIP console log. In z/VM 5.4 there is an ETHERNET statement on the LINK (type QDIOETHERNET) statement. This capability is not in z/VM 5.3. > Do I need to talk to the network people?

Remember, however, that with Layer 2 the virtual MAC address will appear on the REAL network. Therefore it must be unique within the LAN segment. With a single VM system you're ok, but with two or more systems on the same LAN segment, you need to use the MACPREFIX in SYSTEM CONFIG to set the prefix to be unique.
