<h1 class="topictitle1">SNA exchange identifiers (XIDs)</h1>
|
|
<div><p>To establish a connection, your server and the remote device both
|
|
send an XID.</p>
|
|
<p>The exchange identifier is defined in the controller description for your
|
|
server. SNA hosts that use parallel connections require the XIDs. Your server
|
|
conducts an initial poll with NULL XIDs during the connection process, to
|
|
determine whether the remote device is active. If the device
|
|
responds to the poll, your server and the remote device exchange XIDs and
|
|
establish the connection.</p>
|
|
<p>The controller description for an SNA host names the XID value as the local
|
|
exchange identifier. The APPC controller description names the XID value as
|
|
the exchange identifier. Other controller types, such as CTRL, FNC, and RWS,
|
|
also use the exchange identifier.</p>
