PORT definition statement

Code one PORT definition statement for each VBUILD TYPE=XCA definition statement. The PORT definition statement defines the VTAM® connection to a shared access transport facility, such as:

• A CSMA/CD 802.3 LAN, a token-ring network, or a FDDI LAN attached through an IBM® 3172 Nways Interconnect Controller, an Open Systems Adapter, or through an IP network for Enterprise Extender.
• An ATM network attached through an Open Systems Adapter through LAN emulation access
  Note: ATM networks attached through an Open Systems Adapter through LAN emulation access are defined to VTAM as though they are CSMA/CD 802.3 LANs or token-ring networks.
• An ATM network attached through an Open Systems Adapter through native ATM access.

The PORT definition statement also defines the actual adapter on the IBM 3172 Nways Interconnect Controller, Open Systems Adapter, or through an IP network for Enterprise Extender through which the connection is made.
