Configuring for Token-Ring Support
This section shows SNAX/APN users what is required to configure a NonStop system
for communication through a Token-Ring LAN, and includes information about:

Uses for Token-Ring Networks which outlines the principle ways you can use the
SNAX/APN implementation of Token-Ring.

The Architecture of Token-Ring Networks which introduces the concepts of tokens,
protocol layers, service access points, and link stations. This background
information is necessary to understand the line and physical unit attributes used to
configure Token-Ring support.

The HP Implementation which describes the SNAX/APN implementation of support
for Token-Ring. This subsection introduces the configuration requirements for
LINE, PU, and LU objects.

Configuration Example which shows sample SCF commands implementing a
Token-Ring connection between a NonStop system and a host system.
If you are running SNAX/APN on an Integrity NonStop NS-series server with an H-
series operating system, SNAX/APN can communicate through a Token-Ring LAN only
when the server is attached to an HP NonStop™ S-series enclosure, which can
support Token-Ring Servernet adapters. I/O adapter module (IOAM) enclosures can
contain Ethernet adapters (G4SAs), but not Token-Ring Servernet Adapters (TRSAs).
Uses for Token-Ring Networks
There are three main purposes for connecting NonStop systems to Token-Ring
networks:

To allow NonStop systems to participate in high-speed file transfers between
mainframes in the corporate data center—a host-to-host requirement.

To allow NonStop systems to communicate more quickly with SNA devices.

To enable NonStop systems to participate in high-speed application-to-application
communications with SNA-compliant computers and workstations located on LANs
and WANs in a corporate network—a client/server requirement.
You can configure a SNAX/APN Token-Ring line that serves all three purposes.
SNAX/APN PUs and SNAX/XF PUs can share a single line to a Token-Ring network.
