Configuring SNA Resource Manager 49

LU Configuration

Logical Units (LUs) act as ports through which an operator, printer, or host can

communicate between one another. Each 3270 Node definition can support up

to 254 logical units (LUs). Each 5250 Node definition can support up to 8 LUs

per 5251 or 5294 controller emulation, up to 16 LUs per 5394 controller

emulation, and up to 56 LUs per 5494 controller emulation.

Below is a list of supported LU types:

Note

LUs can be assigned non-consecutively. The LU address assignment of

5251 or 5294 controllers is from 0x00 to 0x1F (31 decimal), from 0x00 to 0x14

(20 decimal) for 5394 controllers, and from 0x00 to 0x37 for 5494 controllers.

For 3270 Nodes addresses range from 0x01 to 0xFE (1 - 254).

Logical Unit configuration allows you to define LUs for the system. Select the

LUs component in the SNA Resource Manager tree to view a list of configured

LUs.

Each LU you define must have a unique name on the system. The LU number,

on the other hand, is only required to be unique for the Node it is assigned to.

LU Type Description

LU 0 Application to terminal (end user defined format)

LU 1 Application to printer (3270 SNA Character String)

LU 2 Application to display (3270 data stream)

LU 3 Application to printer (3270 data stream compatibility)

LU 4 Application to printer (5250 printer data stream)

LU 6.2 Application to application support (APPC dependent)

LU 7 Application to display (5250 data stream)
