<h1 class="topictitle1">SNA connections to LAN protocols</h1>
|
||
|
|
<div><p>You or the system can connect Systems Network Architecture (SNA)
|
||
|
|
to a LAN protocol by using one or more service access points (SAPs).</p>
|
||
|
|
<p>Multiple SAPs allow you to have multiple connections between
|
||
|
|
SNA and a LAN protocol, thus permitting multiple communication paths between
|
||
|
|
independent applications.</p>
|
||
|
|
<p>You or the system specifies the SAPs to use in the line and controller
|
||
|
|
descriptions. For SNA, the system can automatically create one SAP value (the
|
||
|
|
default value). There might be cases where you want to change this value or
|
||
|
|
have additional SAPs:</p>
|
||
|
|
<ul><li>The remote system does not use the default source service access point
|
||
|
|
(SSAP).</li>
|
||
|
|
<li>You want parallel station-to-station connections between adapters. This
|
||
|
|
might be what you want if you link two applications that require different
|
||
|
|
controller descriptions.</li>
|
||
|
|
<li>You want station-to-station connections to the same adapters. You might
|
||
|
|
want to do this to configure multiple SAPs to test an application on a single
|
||
|
|
system.</li>
|
||
|
|
</ul>
|
||
|
|
<p>If you plan to change the SAP defaults, see <a href="rzajuyoursaps.htm#your_saps">your
|
||
|
|
SAPs</a> for guidelines and other information.</p>

|
||
|
|
<p>Local SAPs are known as source service access points (SSAPs). The remote
|
||
|
|
SAPs are known as destination service access points (DSAPs). Your system sends
|
||
|
|
data from a SSAP to a DSAP.</p>
