This is normal. :-) The more you read, the more confused you will become. Often, confusion about VSWITCHes comes from "knowing too much" about the rest of VM. > I am running z/VM 5.3 and trying to set up a VSWITCH between this and my > z/Linux guests.

My contact numbers are below. I'll post here, so that others can benefit. 1. XAUTOLOG DTCVSW1 & 2. You did that. 2. Do not change any PROFILE TCPIP anywhere. If you have a CONTROLLER statement in your production PROFILE TCPIP, remove it. 3. DEFINE VSWITCH, specifying one or more available OSAs. Those OSAs (a) SHOULD NOT be shared with any other stack or LPAR, and (b) MUST all go to the same LAN segment. 4. SET/MODIFY VSWITCH to authorize the Linux guests. 5. Add a NICDEF statement to each Linux user directory entry. It is ok that each user reference the same virtual address. 6. Recycle the Linux guests (logoff/logon). Whatever default gateway the Linux guests are using must be defined in the physical switch. Alan Altmark z/VM Development IBM Endicott
