<h1 class="topictitle1">Set the number of virtual devices</h1>
<div><p><span>You can read this topic for instructions on
configuring the number of virtual devices for the Telnet server and limiting
the number of signon attempts allowed.</span></p>
<div class="section">You can enable the Telnet server to automatically configure a set
number of virtual devices and controllers using the QAUTOVRT Devices System
Values. You can specify the number of devices that are automatically started
and the maximum number of devices that the iSeries™ server automatically configures.
The iSeries server
configures or creates one device at a time, as needed, up to a specified limit.</div>
<ol><li class="stepexpand"><span>In iSeries Navigator,
select <span class="menucascade"><span class="uicontrol">your iSeries server</span> &gt; <span class="uicontrol">Configuration
and Service</span> &gt; <span class="uicontrol">System Values</span></span>.</span></li>
<li class="stepexpand"><span>In the right pane, right-click <span class="uicontrol">Devices</span> and
select <span class="uicontrol">Properties</span>.</span></li>
<li class="stepexpand"><span>On the <span class="uicontrol">Devices System Values</span> page, enable <span class="uicontrol">Pass-through
devices and TELNET</span> and select an option for the automatic configuration
of virtual devices. The options are:</span> <ul><li><span class="uicontrol">No maximum number of devices</span> - Allow an unlimited
number of devices</li>
<li><span class="uicontrol">Maximum number of devices (1-32500)</span> - Specify a
value between 1 and 32500 for the maximum number of devices that may be configured
automatically.</li>
<li><span class="uicontrol">Run registered exit program</span> - Call the program
registered for the Virtual Device Selection (QIBM_QPA_DEVSEL) exit point when
a virtual device needs to be selected or automatically created.</li>
