WAN Subsystem Objects
SUBSYS Object
The SUBSYS object represents the WAN manager process, $ZZWAN. There can be
only one WAN manager process per system. The WAN manager can support from one
to 16 ConMgr processes, one or more WANBoot processes, one or more ADAPTER
objects, and up to 3600 DEVICE objects.
ADAPTER Object
The ADAPTER object represents the SWAN concentrator. There is one ADAPTER
object per SWAN concentrator. One ADAPTER object can support up to three
SERVER objects for the SWAN concentrator and six SERVER objects for the SWAN 2
concentrator.
SERVER Object
The SERVER object represents one communications line interface processor (CLIP).
There can be up to three SERVER objects on one ADAPTER object for the SWAN
concentrator and up to six SERVER objects for the SWAN 2 concentrator. One
SERVER object can support as many as two PATH objects and two TASK objects.
TASK Object
The TASK object represents a data link control (DLC) task. There can be up to two
DLC TASK objects on one SERVER object. One DLC task controls one WAN line
interface. Each WAN port on a CLIP can run a different DLC task.
PATH Object
The PATH object defines an Ethernet path on a CLIP by defining an IP address to each
Ethernet port interface (SCC1 and SCC2) on each CLIP on the SWAN concentrator.
The IP addresses are assigned through the BOOTP exchange. There can be up to two
PATH objects on one SERVER object or six PATH objects on one SWAN concentrator.
Note. Because the WAN manager process is configured as a subsystem manager process in
the NonStop Kernel subsystem, you must use the NonStop Kernel subsystem SCF interface to
configure and control it. The SCF interface to the NonStop Kernel subsystem is described in
the SCF Reference Manual for the Kernel Subsystem.
