OSI/TS SCF Commands Changed to Support RFC-1006

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

107751 Tandem Computers Incorporated 3–3

LOCALNSAP (ZLOC-NSAP)

defines the local IP address for TCP/IP networks.

Value: Dotted decimal notation or eight-digit hexadecimal string.

Default: No default value is provided.

NSPDEVICE (ZNSP-DEV)

specifies the name of the local TCP/IP process. The TCP/IP process must exist,

but does not need to be on the same system as the OSI subsystem.

Value: To obtain a list of the possible values, issue the following SCF

command:

LISTDEV TCPIP

Default: No default value is provided.

REMOTENSAP (ZRMT-NSAP)

defines the remote IP address for TCP/IP networks.

Value: Dotted decimal notation or eight-digit hexadecimal string.

Default: No default value is provided.

TPDUSIZE (ZTPDU-SIZE)

specifies, in bytes, the maximum length of a TPDU.

The TPDU size is negotiated between transport peers. The calling transport entity

proposes a TPDU size in the CR-TPDU. The called transport entity compares this

proposed value with its own value and specifies the smaller of the two values as

the negotiated value in the CC-TPDU sent to the calling transport entity.

If the transport entity does not specify a TPDU size in either the CR- or CC-TPDU,

the peer transport entity assumes that 65531 has been proposed/negotiated and

compares that value (65531) to its own value.

Use the INFO SU command to see the value of the configured TPDUSIZE. Use the

STATUS SU command to see the actual TPDUSIZE used when the connection was

established.

Value: 128 | 256 | 512 | 1024 | 2048 | 4096 | 8192 | 16384 | 32768 | 65531

Default: Defaults to the value of the TPDUSIZE attribute in the #L4 SERVICE

command.

Note The OSI/AS MAXCONNECTIONS attribute can restrict the size of the SPDU sent to OSI/TS. Specifying a

smaller value for MAXCONNECTIONS allows the TAPS process to send larger SPDUs. Both the

Tandem OSI/AS SCF Reference Manual and the Tandem OSI/AS Configuration and Management

Manual discuss the MAXCONNECTIONS attribute in more detail.
