Yes, (z/OS 1.6 under z/VM 5.1.0 at the moment).

You do need such a definition to map the "ZVMLAN1" word above to the underlying device number triple. For my configuration, I have DEVICE TRLF7004 MPCIPA NONROUTER LINK LNKLOCAL IPAQENET TRLF7004 for a virtual NIC interface onto a GuestLAN and the corresponding VTAM definition (continuation characters omitted): TRLV7004 VBUILD TYPE=TRL * * TRLF7004 TRLE LNCTL=MPC, READ=7004, WRITE=7005, DATAPATH=7006, PORTNAME=OSA7004, MPCLEVEL=QDIO -- Malcolm Beattie <[EMAIL PROTECTED]> Linux Technical Consultant, IBM Europe System z Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
