SNAplus2 Resources
SNAplus2 Resources
Node resources define the communications capabilities of the APPN
node, including connectivity resources (ports and link stations), LUs
(type 0–3 for 3270, RJE, and LUA communications, and type 6.2 for
APPC and CPI-C communications), modes, and directory information.
Domain resources are available to all of the SNAplus2 systems in the
local network; such resources are used to support particular user
programs. Domain resources include RJE workstation definitions, 3270
user information, CPI-C side information, and information about access
to the UNIX command facility and the service point command facility.
NOTE In some cases, the SNAplus2 Motif administration program simplifies
the presentation of resources (as compared to the command-line
administration program). You do not need to know what these
differences are unless you intend to use both the Motif and
command-line programs. In this case, details can be found in HP-UX
SNAplus2 Administration Guide.
Node Resources
The following resources can be defined on individual nodes:
Ports
A port represents the local end of a communications
link as a unique access point in the network.
Each port is associated with a specific link protocol,
which can be any of the following:
• SDLC (synchronous data link control)
• X.25 QLLC (qualified logical link control)
• Token ring
• Ethernet
• FDDI (Fiber Distributed Data Interface)
More than one port can be associated with a particular
link protocol.
In general, a port corresponds to a single physical
access point, such as an adapter card. However, for
some link protocols (such as token ring), you can define
