<h1 class="topictitle1">Connection establishment between LAN devices</h1>
|

|
<div><p>If you use Systems Network Architecture (SNA) with a LAN protocol,
|
||
|
|
use this information to establish the connection between LAN
|
||
|
|
devices. </p>
|
||
|
|
<p>The correct relationship between a line description and
|
||
|
|
a controller description helps to ensure connection establishment. A controller
|
||
|
|
description determines which line descriptions your system uses. Therefore,
|
||
|
|
you must ensure that the controller description refers to the correct line
|
||
|
|
description.</p>
|
||
|
|
<p>Also, a line description governs the number of active controllers that
|
||
|
|
can access it. By making the number too small, you might prevent the controller
|
||
|
|
description from accessing the line description. Therefore, you should ensure
|
||
|
|
a large enough value to allow the controller description access to the line
|
||
|
|
description.</p>
|
||
|
|
<p>Besides the correct relationship between the line and controller descriptions,
|
||
|
|
the descriptions must also contain the correct information to ensure connection
|
||
|
|
establishment. The following information discusses some of the connection
|
||
|
|
information that you are responsible for.</p>
