<h1 class="topictitle1">SNA service access points (SAPs)</h1>
|

|
|
<div><div class="section"><p>On the server, you define the source SAPs (SSAP). If you decide
|
||
|
|
to change the default SAPs or add more SAPs, you must define them in the line
|
||
|
|
and controller descriptions. You can specify up to 24 SSAPs per line description
|
||
|
|
when you define the SAPs. The SSAPs that your controller description uses
|
||
|
|
must also be defined in the line description associated with the controller
|
||
|
|
description. Your controller description also specifies the destination service
|
||
|
|
access point (DSAP).</p>
|
||
|
|
<p id="rzajysnaserviceaccesspoints__ssaps_and_dsaps"><a name="rzajysnaserviceaccesspoints__ssaps_and_dsaps"><!-- --></a>Local SAPs are known as source
|
||
|
|
service access points (SSAPs). The remote SAPs are known as destination service
|
||
|
|
access points (DSAPs). Your server sends data from an SSAP to a DSAP.</p>
|
||
|
|
<p>The
|
||
|
|
following figure portrays the physical connection between the source service
|
||
|
|
access points of your iSeries and the destination service access
|
||
|
|
points of the remote system. For example, on your server, the SSAP 08 will
|
||
|
|
have a DSAP of 12. On the remote system, the SSAP is 12 and the DSAP is 08.</p>
|
||
|
|
<br /><img src="rzajy501.gif" alt="This figure shows an example of
the relationship between SSAP and DSAP pairs." /><br /><p>For SNA, you
|
||
|
|
must use certain SSAP values. You can find the help for selecting these values
|
||
|
|
by pressing F1 (Help) while your cursor is on the SSAP list field of the line
|

description.</p>
