Either a TCP/IP or an SNA APPC connection must be enabled to support ISPF Client/Server (C/S) communication between an MVS™ host and a workstation. Subsequent topics describe what must be configured at the host and at a workstation for both TCP/IP and SNA APPC connections. Configuration of 3270 terminal type connections that support user logon to MVS TSO is not described here. A configuration fast path is provided at the beginning of the discussion of each type of connection.
Although a few elements of ISPF C/S configuration must be coordinated between a workstation and the MVS host, ISPF users will generally be more concerned with workstation requirements. MVS system or network support personnel will generally be more concerned with MVS host requirements.
