<div><p>Learn about the types of verification used during the connection
|
||
|
|
process.</p>
|
||
|
|
<p>To begin a connection, your server sends information to the remote device
|
||
|
|
you are connecting to. The device identifies the server using this information.
|
||
|
|
The device then sends information back to the server, which the server uses
|
||
|
|
to identify the device. The server compares that information against the information
|
||
|
|
that is contained in the line and controller descriptions. If a match occurs
|
||
|
|
and other connection values are correct, the connection process continues.
|
||
|
|
In the meantime, the remote device performs a similar process.</p>
|
||
|
|
<p>Your server and the remote device use two types of verification during
|
||
|
|
the connection process. The first type (required), matches the line and controller
|
||
|
|
description information with the connection information that the remote device
|
||
|
|
sent. Once the information has been verified, your server continues the process.</p>
|
||
|
|
<p>The remote device sends the following information:</p>
|
||
|
|
<ul><li>The MAC address associated with the input/output adapter (IOA) on the
|
||
|
|
remote device (either preset or locally administered)</li>
|
||
|
|
<li>The source service access point (SSAP) on the remote device</li>
|
||
|
|
<li>The destination service access point (DSAP)</li>
|
||
|
|
</ul>
|
||
|
|
<p>The other type of verification matches the SNA exchange identifier values.
|
||
|
|
SNA hosts that use parallel connections require this verification. This verification
|
||
|
|
is optional for advanced program-to-program communications (APPC).</p>
