Mark, It looks like you and I are working on the same projects in regards to Linux and Open Solaris and layer 2 and layer 3 virtual switches. As to SuSE Linux, yes, it can work in layer 2 mode. This from Novell: You should just be able to edit the /etc/sysconfig/hardware/hwcfg-qeth-??? file and add this line: QETH_LAYER2_SUPPORT='1' Or, change the existing one that says "QETH_LAYER2_SUPPORT='0'" to that. I have yet to try this, so if you do, please let me know how it works for you. TIA and HTH HITACHI DATA SYSTEMS Raymond E.

Latest layer 2 / layer 3 vswitch question. Within z/VM 5.4, can I have 1 layer 2 switch for my guests that support only layer 2, and a layer 3 switch for linux and TCPIP? Both would be connected to the same OSA (z9) via different triplet addresses. Next thing I've got to figure out is how to change a running SuSE linux guest from a layer 2 vswitch to a layer 3 vswitch.

Guess I'll get to try it when I get to my Linux only z/VM system.
