TS Supplement (Includes RFC-1006 Support)

OSI/TS SCF Commands Changed to Support RFC-1006

RFC-1006 Changes to the SCF, SPI, and PTrace Subsystems

107751 Tandem Computers Incorporated 3–13

NSP SU (ZNSP-SU)

shows the name of the network I/O process subdevice created by TSP to convey

transport protocol data units (TPDUs). The name shows either a network I/O

process subdevice currently in use for an active transport connection or for

receiving a connection, or the name is the network I/O process subdevice last used

by the TSP to convey TPDUs over this subdevice.

The TCP/IP process does not use subdevices to interface to the application process

(TSP). When the NSP is TCP/IP, the value displayed here is not a true TCP/IP

subdevice (you can’t issue a command such as STATUS SU

tcp/ip-su

). When

TCP/IP is the NSP, the TCP/IP subdevice is used internally by TSP to identify the

connection. The subdevice displayed is useful in troubleshooting as it is also

available in NETIO trace records and the EMS log.

NSP Subsys (ZNSP-SUBSYS)

Indicates which type of NSP subsystem is being used by this SU, “X25AM,”

“TLAM,” or “TCP/IP.”

In the SPI interface, the value for the new string is ZOS4-VAL-NSP-SUBSYS-TCPIP

(value of 3).

NSPFSErrorCode (ZNSP-FS-ERRCODE)

shows the NSP file-system error code if an error has occurred. This error can

originate in the TCP/IP subsystem.

Class (ZCLASS)

shows the preferred protocol class.

T-Expedited (ZL4-EXPEDITED)

shows whether the transport expedited data transfer service is supported.

TPDU Size (ZTPDU-SIZE)

shows the maximum length of a TPDU.

LocalNSAP (ZLOC-NSAP)

shows the local IP address. Both the dotted decimal notation and eight-digit

hexadecimal string are displayed.

RemoteNSAP (ZRMT-NSAP)

shows the remote IP address. Both the dotted decimal notation and eight-digit

hexadecimal string are displayed.
