<h1 class="topictitle1">Scenario details: Configuration for the iSeries™ system in Minneapolis</h1>
<div><div class="section"> <p>Use the prompt display for the Create Network
Interface (Frame Relay) (CRTNWIFR) command to create the network
interface (NWI) description on the Minneapolis system. The INTERFACE and LINESPEED
parameter values must match the network subscription, and you must specify
a LMIMODE value when communicating over a frame-relay network. The LMIMODE
value must match the network subscription and can be *TE, *ANNEXA, or *NONE.
The local management interface (LMI) uses data link connection identifier
0 (DLCI 0) for both *ANNEXA and *TE, but it does not use a DLCI for *NONE.</p>
<p>Use the prompt display for the Create Line Description (Frame
Relay) (CRTLINFR) command to create the frame-relay line description on the
Minneapolis system. The DLCI that you specify for the line must match the
network subscription. Because frame-relay Systems Network Architecture (SNA)
direct addressing requires 10 bytes of overhead, a frame size of 1590 is configured
for the MAXFRAME parameter. In other words, you need to use a frame size that
is at least 10 bytes less than the network subscription. You also need to
know the frame size at the other side of the network. For example, if one
side is 1600 and the other is 2100, then both sides need to be set to 1600.</p>
<p>Use
the prompt display for the Create Controller Description (APPC) (CRTCTLAPPC)
command to create the APPC controller description on the Minneapolis system.
You must specify LINKTYPE(*FR) for SNA direct connections.</p>
<div class="note"><span class="notetitle">Note:</span> The default
values for SSAP and DSAP are both 04. These values must match the values specified
for the remote system. If you create more controllers using the same line
description (DLCI), you must specify a unique SSAP and DSAP pair. This might
require you to configure more SAPs on the frame-relay line description.</div>
