Step 1: Add the SNAX/APN Line
Step 1: Add the SNAX/APN Line
At least one SNAX/APN line must be configured and started at each end of the SNA
network through which the Expand-over-SNA line-handler process will communicate.
You use the SNAX/APN subsystem SCF ADD LINE command to configure a
SNAX/APN line. For example, the following command creates a SNAX/APN line called
$SNAPA:
-> ADD LINE $SNAPA, RECSIZE 524, MAXPUS 1, MAXLUS 30, &
STATION PRIMARY, MAXLOCALLUS 10, POLLINT 0.01
For details about configuring SNAX/APN lines, refer to the SNAX/XF and SNAX/APN
Configuration and Management Manual. SCF ADD LINE attributes are also described
in the SNAX/XF and SNAX/APN Configuration and Management Manual.
Considerations
POLLINT should be set to the minimum value (0.01 seconds) on Synchronous Data
Link Control (SDLC) lines for best performance.
Step 2: Add the LUs for the SNAX/APN Line
You must configure a local and a remote logical unit (LU) for the SNAX/APN line. The
Expand-over-SNA line-handler process is configured to use a particular local LU.
You use the SNAX/APN subsystem SCF ADD LU command to add the local LU. For
example, the following command creates a local LU with a subdevice name of #LLUA
for the SNAX/APN line $SNAPA:
->
ADD LU $SNAPA.#LLUA, TYPE (14,21), SNANAME LUA, PROTOCOL NAM, &
DLUNAME #RLUA, RSPTYPE ER
Before you can add the remote LU, you must add a remote physical unit (PU); the
remote LU will be subordinate to this PU. You use the SNAX/APN SCF ADD PU
command to add a remote PU. For example, the following command creates a remote
PU with a subdevice name of #RPUA for the SNAX/APN line $SNAPA:
-> ADD PU $SNAPA.#RPUA, TYPE (13,21), ADDRESS %HC1, RECSIZE 521, &
MAXLUS 30
After you have created the remote PU, you use the SNAX/APN subsystem SCF ADD
LU command to add the remote LU. For example, the following command creates a
remote LU with a subdevice name of #RLUA for the SNAX/APN line $SNAPA:
-> ADD LU $SNAPA.#RLUA, TYPE (14,21), SNANAME LUB, PUNAME #RPUA
Note. The following instructions assume that a SNAX/APN line-handler process has already
been created. To create such a process, you must add it as a device to the WAN subsystem.
For information about creating SNAX/APN line-handler processes, refer to the WAN
Subsystem Configuration and Management Manual.
