Let me back up and explain what we are trying to do and see if I understand what needs to be in the IOCP to accomplish this. We currently have a few dozen linux instances running within a Z/VM Lpar. They have VCTC links to the VM/TCPIP stack (acting as the route to the internet). We are trying to move the LINUX instances to an IFL LPAR where they will eventually be defined on a Vswitch (or a Guest Lan with a VM TCP/IP router). To avoid having intermediate changes in the PIX firewall and Cisco routers, we were trying to extend the LINUX CTC links from the existing TCP/IP (in the non-IFL LPAR) to the IFL Linux machines with real CTCs instead of the existing VCTCs. Since we had RSCS, VTAM and JES working with SCTC device/links we thought these links would also work with TCP/IP. (and it sounds like it would have if we were talking from Z/OS TCP/IP to Linux TCP/IP) What I think I'm hearing is that VM TCP/IP only supports BCTC (Parallel Basic Mode CTC support over ESCON). So now, if I define another pair of CHPID's (CTC/CNC) and define the IODEVICES on these links as BCTC units, then I think I'm hearing that the VM TCP/IP in the non IFL LPAR should be able to communicate with a LINUX quest in the IFL LPAR. I think the ccw_chan_mode parm in SLES specifies the type of CTC link. I think "0" would correspond to BCTC. >CCW_CHAN_MODE="0" If we're still off base we are open to further clarification.
