4 SNAX/XF Secondary Lines
SNAX/XF secondary lines connect a NonStop system to an SNA host (type 5 node),
typically through an SNA communication controller (type 4 node). Connections
between the NonStop node and SNA hosts can be point-to-point or multipoint. The
NonStop system appears to the SNA host as an SNA peripheral node (type 2.0 node).
Applications on the NonStop system can use the SNAX/APC, SNAX/HLS, or SNALU
APIs.
SNAX/XF lines, PUs, and LUs used for SNA host communication are called gateway
lines, PUs, and LUs.
The rest of this section is structured as follows:

Configuring the SNA network
Configuring SNAX/XF Secondary Lines
You should have performed Tasks 1 through 3 of Configuration Quick Start in
Section 1, SNAX Quickstart and Overview. You now use SCF to add and start the
LINE, PU, LU, and APPL objects you need.
Figure 4-1 on page 4-2 shows an example of a secondary SDLC line with three host
applications accessible from the NonStop system. The SNAX/XF SCF configuration,
shown alongside, configures one gateway PU and one gateway LU.
