<li class="stepexpand"><span>Type the name of the controller description into the Controller

between the line and controller descriptions, see <a href="rzajuunderstandingconnestablishment.htm#understanding_conn_establishment">connection

of the remote IBM<sup>®</sup> <span><img src="eserver.gif" alt="eServer" /></span> <span class="keyword">iSeries™</span> system.
|
|
Use the Display Network Attributes (DSPNETA) command on the remote system

<li><em>Exchange identifier</em> contains the <a href="rzajuexchangeidentifiers.htm#exchange_identifiers">exchange

identifier</a> for your system. Advanced Program-to-Program Communication

the first part, press F1 (Help) when your cursor is on this field. You can
|
|
get the value for the second part from the line description on the remote

system that is used to connect to your system. To understand the purpose of

exchange identifiers, read <a href="rzajuunderstandingstationids.htm#understanding_station_ids">How

Parallel connections between your system and a Systems Network Architecture

adapter (IOA). To find this address, see <a href="rzajuviewingyouradapteraddress.htm#viewing_your_adapter_address">View
