<h1 class="topictitle1">Example: Create parallel connections to a host</h1>
|
||
|
|
<div><p>This example connects your system to a host system through a 3745
|
||
|
|
Communications Controller by using parallel connections.</p>
|
||
|
|
<p>Each connection has a separate instance of the logical
|
||
|
|
link control and a separate bandwidth. Thus, communications can still occur
|
||
|
|
even if one link becomes nonfunctional.</p>
|
||
|
|
<p>Because all the examples use the same token-ring line description, this
|
||
|
|
example discusses only the controller and device descriptions. You can find
|
||
|
|
the configuration for the 3745 controller in Example: Configure the physical
|
||
|
|
and logical parallel connections on the host system.</p>
|
||
|
|
<p><strong>Controller descriptions:</strong></p>
|
||
|
|
<p>In this example, focus on these points:</p>
|
||
|
|
<ul><li>The controller descriptions use the same line description.</li>
|
||
|
|
<li>The controller descriptions use different local exchange IDs. You must
|
||
|
|
use exchange IDs to establish parallel connections.</li>
|
||
|
|
<li>The controller descriptions use different source service access points <a href="rzajuhigherlayersoverlanprotocols.htm#higher_layers_over_lan_protocols__ssaps_and_dsaps">(SSAPs)</a>.</li>
|
||
|
|
<li>The 3745 Communications Controller requires that you specify 04 for the
|
||
|
|
destination service access point <a href="rzajuhigherlayersoverlanprotocols.htm#higher_layers_over_lan_protocols__ssaps_and_dsaps">(DSAP)</a>.</li>
