SCF Commands Used to Configure OSI and MHS
The 1980 version of X.25 does not contain the addressing extensions to carry the
NSAP address in the OSI network layer, and therefore the NSAP address is derived
from the X.25 NUA. The 1984 version of X.25 has the necessary addressing
extensions, and therefore the NSAP address can be carried in the X.25 call request
packet and be independent of the X.25 NUA.
This appendix emphasizes the requirements for addressing in an X.25(1980) network
environment because most X.25 networks today support that version of the CCITT
recommendation.
SCF Commands Used to Configure OSI and
MHS
The OSI addressing for an MTA connection is configured both in the OSI/MHS
subsystem and in the OSI stack (OSI/AS and OSI/TS). This appendix does not explain
the SCF commands in detail. Refer to the OSI/MHS SCF Reference Manual for a full
explanation of the commands.
In OSI/MHS, you specify the OSI addresses using the SCF commands ADD GROUP
#MR and ADD MTA.
In the OSI stack, the OSI addresses are configured using the ADD ENTRY and ADD
PROFILE commands.
You specify the following address parameters in the ADD GROUP #MR command:
MR-P-SELECTOR (optional)
MR-S-SELECTOR (optional)
MR-T-SELECTOR (optional)
MR-NSAP
You specify the following address parameters in the ADD MTA command. In this list, n
represents a number in the range of 1–7:
LOC-PSELECTORn (optional)
LOC-SSELECTORn (optional)
LOC-TSELECTORn (optional)
LOC-NSAPn
REM-PSELECTORn (optional)
REM-SSELECTORn (optional)
REM-TSELECTORn (optional)
REM-NSAPn
For each -TSELECTOR value you define, there must be a corresponding ADD ENTRY
#TSEL command in the OSI stack.
For each -NSAP value you define, there must be an ADD ENTRY #NSAP command
and possibly an ADD ENTRY #SNPA, an ADD PROFILE #L3 command, or both.
