I'm trying to create a Virtual Switch LAN (on first-level CP) which does not extend outside the CP operating system. To do this I create a Virtual Switch called INTRAV6 via the z/VM SYSTEM CONFIG file:
Define VSwitch INTRAV6 RDev NONE Connect Controller TCPIPOSA ETHernet I do the usual: CP Set vswitch intrav6 grant zvm520 In the directory for the second-level node (in this case ZVM520), I have: NICDEF D00 TYPE QDIO DEVICES 3 LAN SYSTEM INTRAV6 On the TCPIP userid (third-level) I have a DTCPARMS file to attach the device at logon-time for TCPIP running under guest ZVM520: :nick.TCPIP :type.server :name.zVM520 TCP/IP Stack :class.stack :attach.0500-0502 , 0D00-0D02 And a PROFILE TCPIP which contains: DEVICE INTRANET OSD 0500 PORTNAME INTRANET PRIROUTER LINK INTRANET QDIOETHERNET INTRANET MTU 1500 DEVICE INTRAV6 OSD 0D00 PORTNAME INTRAV6 PRIROUTER LINK INTRAV6 QDIOETHERNET INTRAV6 MTU 1500 ENABLEIPV6 HOME 141.202.200.35 255.255.255.0 INTRANET FD00:7A06:0A33:0003:0000:0000:0000:F5F2 INTRAV6 GATEWAY ; (IP) Network Subnet First Link Packet ; Address Mask Hop Name Size ; --------------- --------------- --------------- -------- ------ DEFAULTNET 141.202.200.101 INTRANET 1500 DEFAULTNET6 FD00:7A06:0A33:0003:0000:0000:0000:0001 INTRAV6 1500 START INTRANET START INTRAV6 TCPIP's console shows errors: 09:33:32 DTCIPI023I TCP-IP initialization comlete. 09:33:32 DTCOSD066E OSD device INTRAV6: ToOsd ProcessReadBuffer: Termination failure code F6 09:33:32 DTCOSD355E OSD device INTRAV6: Possible LAN transport misconfiguration detected during OSD device initialization. 09:33:32 DTCOSD082E OSD shutting down: 09:33:32 DTCPRI385I Device INTRAV6: 09:33:32 DTCPRI386I Type: OSD, Status: Inoperative 09:33:32 DTCPRI387I Envelope queue size: 0 09:33:32 DTCPRI388I Address: 0D00 I also note in the TCP/IP message manual: DTCOSD355E Possible LAN transport misconfiguration detected during OSD device initialization Explanation: An adapter error was received during initialization. This message is preceded by message DTCOSD066E with the error code. Possible reasons for error code F6 are: - The adapter was coupled to a guest LAN or virtual switch with the ETHERNET transport type. However, the TCP/IP z/VM OSD device driver does not support this transport type. And CP DEFINE VSWITCH usage notes says: The IP transport type is IPv4 only. In order to support IPv6 through the virtual switch RDEV, the ETHERNET transport is required. In long last, my questions: Is it possible to have a IPV6 Virtual Switch used by TCP/IP on VM?
