WAN Subsystem Objects for SNAX
Processes
This subsection describes how to configure SNAX service managers and line handlers
through the WAN subsystem.
NonStop S-Series servers communicate across wide-area networks through the
ServerNet wide area network (SWAN) concentrator. The WAN subsystem provides a
software interface to the SWAN concentrator. The WAN subsystem includes a WAN
manager process ($ZZWAN) through which you configure some of the objects for HP
wide-area communication subsystems. The WAN manager process stores objects in a
configuration data base. The WAN subsystem is fully described in the WAN Subsystem
Configuration and Management Manual. SNAX supports both SWAN and SWAN 2
concentrator.
The rest of this section is structured as follows:

Configuring a SWAN concentrator

Configuring a SWAN Concentrator
Figure 2-1 shows the WAN subsystem SCF configuration of a SWAN concentrator:

An ADAPTER object defines the SWAN concentrator.

A SERVER object defines a communications line interface processor (CLIP).
There are three CLIPS in a SWAN concentrator, with two lines per CLIP.

A PATH object defines an Ethernet path to a CLIP. There are two paths to a CLIP.

A TASK object defines a data link control (DLC) task running in each CLIP. There
are two DLC tasks in each CLIP, each controlling one WAN line interface.
