sap

CFTPROT

[SAP = string32 ]

Name of the local SAP, Service Access Point, associated with this protocol. It is used to identify the access point at which incoming connection requests for this communication protocol are placed.

The value of the SAP depends on the data exchange protocols used by each access method.

The SAP supplied by a requester partner when making its connection request is retrieved by the local Transfer CFT which uses it to deduce the protocol to be used. Each CFTPROT command in a given resource class must include its specific SAP.

The value of this parameter may be expressed in hexadecimal form. In this case, the first character must be "#" (number sign) (for example: #31 is understood as the ASCII character ‘1’).

If the SAP parameter is not set to a value for a given protocol, that protocol is only available in requester mode.

TCP/IP

Number of the local monitoring port on which the monitor can be called, expressed in the form of the:

  • real number used by TCP/IP:
  • authorized numbers: between 1025 and 65535
  • recommended numbers: 1761, 1762, 1763, 1764, 1765, 1766, 1767, 1768 (1)
  • logical name associated with the number used by TCP/IP and configured in the SERVICES file (if this file exists)

    recommended logical names: cft-0, cft-1, cft-2, cft-3, cft-4, cft-5, cft-6, cft-7 (1)

(1): these logical port numbers and names have been officially reserved by Sopra from the IANA (Internet Assigned Numbers Authority).

CFTPART

[SAP = (string, string, string, ...) ]

Values of the remote SAPs (service access points) associated with each of the protocols defined by the PROT parameter.

For transfers to a Transfer CFT other than the Transfer CFT, the use of this additional information should be looked into on a case by case basis.

For transfers to a Transfer CFT , this parameter is used to designate the protocol applied to the partner Transfer CFT. In other words, the "sap" is an additional item of information used to reach a remote application subset (a protocol in the Transfer CFT case) and not only a Transfer CFT.

Each of the values of the parameter represents the "sap" associated with the communication protocol, the identifier of which matches in the PROT parameter.

The maximum number of SAPs equals the maximum number of protocols (see the table for the PROT parameter).

The value of this parameter is specific to each data exchange protocol, and to each system, as applicable, as specified in the table below.

TCP/IP 

1 to 15
 

Number of the port on which the monitor partner is listening.
The value of this number can be:

  • a number in clear corresponding to the real number used by the remote partner at the protocol level of the TCP/IP protocol
    Authorized numbers: between 1025 and 65535 (not including limit values)
    Recommended numbers: between: 1761, 1762, 1763, 1764, 1765, 1766, 1767, 1768 (1)
  • the logical name associated with the number used by TCP/IP and configured in the SERVICES file, if this file exists
    Recommend logical names: cft-0, cft-1, cft-2, cft-3, cft-4,
    cft-5, cft-6, cft-7 (1)

If the local and remote partner parameter setting commands (CFTPART and CFTPROT respectively) use the logical name of the port defined in the "SERVICES" database, the consistency of the two bases must be ensured 

(1) These logical port numbers and names have been officially reserved by SOPRA from the IANA (Internet Assigned Numbers Authority).
