TS Supplement (Includes RFC-1006 Support)

OSI/AS SCF Commands Changed to Support RFC-1006

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

3–18 107751 Tandem Computers Incorporated

ADD PROFILE #L4 The following

attribute-specs

for the ADD PROFILE #L4 command have new

meaning when using RFC-1006:

[ CLASS { 0 | 1 | 2 | 3 | 4 } ]

[ EXPEDITED { ON | OFF } ]

[ TPDUSIZE

{ 128 | 256 | 512 | 1024 | 2048 | 4096 |

8192 | 16384 | 32768 | 65531 } ]

CLASS (ZCLASS)

specifies the preferred transport protocol class.

Value: For TCP/IP networks, CLASS must be 0. If you specify a value other

than 0, during connection establishment, OSI/TS will reject the

connection attempt.

Default: Defaults to the value of the CLASS attribute in the OSI/TS ALTER

SERVICE #L4 command (which is 0).

EXPEDITED (ZEXPEDITED)

specifies whether the transport expedited data transfer service is supported.

Value: ON | OFF

Default: Defaults to the value of the EXPEDITED attribute in the ALTER

SERVICE #L4 command (which is OFF).

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.
