SNAX/XF and SNAX/APN Configuration and Management Manual—425836-006

10-16

Configuration Example

example, PU2, that has an address of 04400011110001 must be connected to PU4

through SAP %H08, the unique address being 04400011110001,08400011110002.

Note that these restrictions apply only to PU-to-PU connections. There may be many

LU-LU sessions channelled through a single PU, and LU6.2 further allows multiple

parallel sessions between two LUs.

Configuration Example

SNAX does not directly control the Ethernet ServerNet adapter. SNAX communicates

with the QIO process and QIO communicates with the Ethernet adapter. The QIO

subsystem is preconfigured and it should require no configuration for SNAX. QIO is a

system process and it should always be running. For information about QIO

configuration and management, see the QIO Configuration and Management Manual.

The Ethernet adapter is configured when the hardware is installed and it should require

no configuration for SNAX. You need to know the name of the Ethernet adapter’s line

interface (LIF) that SNAX will use.

There are only two steps required:



Verify that the Ethernet adapter is ready for communication over the LAN.



Configure the SNAX/XF or SNAX/APN LINE, PUs, and LUs and then start them.

Step One: Verify the Ethernet Adapter’s LIF

Status

Issue the following SCF commands using the name of the LIF that SNAX will use:

->ASSUME PROCESS $ZZLAN

->STATUS ADAPTER <LIF name>

Verify that the LIF’s State is Started its Access State is Up. If not, correct the problem

and reissue the STATUS command. For more information, see the Ethernet Adapter

Installation and Support Guide for the E4SA adapter, the Fast Ethernet Adapter

Installation and Support Guide for the FESA adapter, the Gigabit Ethernet Adapter

Installation and Support Guide for the GESA adapter, or the Gigabit 4-Port ServerNet

Adapter Installation and Support Guide for the G4SA adapter.

Step Two: Configure SNAX

At the SNAX level you choose SNAX/XF for legacy-style, sub-area communications or

SNAX/APN for peer-to-peer communication.

This example uses SNAX/APN. This product allows parallel sessions within a single

LU-LU connection and dynamic configuration of the remote LU.
