Sample configuration with Ethernet or Ethernet-type LAN

Figure 1 shows a multiple domain XCA configuration with an Ethernet or Ethernet-type LAN and two IBM® 3172 Nways Interconnect Controllers.

Figure 1. XCA multiple domain configuration with Ethernet or Ethernet-type LAN

To define the configuration in Figure 1, define the following in the first VTAM®:

One external communication adapter major node to represent the physical unit in the IBM 3172 Nways Interconnect Controller
One external communication adapter major node for each LAN connected to the IBM 3172 Nways Interconnect Controller
Major nodes for any devices connected to the LAN

Following is the sample code for the configuration in Figure 1:

Define an external communication adapter major node to represent the physical unit in the IBM 3172 Nways Interconnect Controller:

XCACON1  VBUILD TYPE=XCA               XCA MAJOR NODE
PORT1    PORT  MEDIUM=BOXMGR,          3172 MANAGER

GROUP1   GROUP ISTATUS=ACTIVE          ACTIVATED AT GEN
LINE1    LINE
PU1      PU

Define another external communication adapter major node for the Ethernet or Ethernet-type LAN:

XCACON2  VBUILD TYPE=XCA               XCA MAJOR NODE
PORT2    PORT  MEDIUM=CSMACD,          Ethernet or Ethernet-type LAN

               CALL=INOUT,             DIAL IN AND OUT
               ISTATUS=ACTIVE          ACTIVATED AT GEN

               TGN=2                   TRANSMISSION GROUP NUMBER

Define a switched major node for the peripheral node attached to the LAN:

SWNODE1  VBUILD TYPE=SWNET
PU2      PU    DISCNT=YES,              DISCONNECT FACILITY
               IDBLK=002,               BLOCK IDENTIFICATION
               IDNUM=00002,             IDENTIFICATION NUMBER
