<p>The <strong>disconnectSNMP()</strong> function ends the logical connection
|
||
|
|
between the SNMP subagent and the i5/OS SNMP agent.</p>
|

|
|
|
||
|
|
<br>
|
||
|
|
<h3>Authorities</h3>
|
||
|
|
|
||
|
|
<p>So that the subagent can receive messages from the SNMP agent, the following
|
||
|
|
conditions must be met:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>The library and data queue whose names are passed as a parameter in the
|
||
|
|
<strong>connectSNMP()</strong> call must exist prior to the call.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>The data queue and library names passed as parameters in the
|
||
|
|
<strong>disconnectSNMP()</strong> call must be the same as used in the
|
||
|
|
previous, successful <strong>connectSNMP()</strong> call.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<br>
|
||
|
|
<h3>Parameters</h3>

|
<dl>
|
||
|
|
<dt><strong>queue_name</strong></dt>
|
||
|
|
|
||
|
|
<dd>(Input) The name of the data queue (as a null-terminated string) on which
|
||
|
|
the subagent was receiving Distributed Protocol Interface (DPI) packets. This
|
||
|
|
should be the same data queue name as previously used in a call to
|
||
|
|
<strong>connectSNMP()</strong>.<br>
|
||
|
|
<br>
|
||
|
|
</dd>
|
||
|
|
|
||
|
|
<dt><strong>lib_name</strong></dt>
|
||
|
|
|
||
|
|
<dd>(Input) The name of the i5/OS library (as a null-terminated string) to
|
||
|
|
which the data queue belongs. This should be the same library name as
|
||
|
|
previously used in a call to <strong>connectSNMP()</strong>.<br>
|
||
|
|
<br>
|
||
|

|
||
|
|
|
||
|
|
<dt><strong>timeout</strong></dt>
|
||
|
|
|

|
for a disconnection. This field may contain any of these values:

<h3>Usage Notes</h3>
|
||
|
|
|
||
|
|
<p>The <strong>disconnectSNMP()</strong> function ends the logical connection
|
||
|
|
between the SNMP agent and a subagent. This is normally the last subagent API
|
||
|
|
that a subagent calls.</p>
|
||
|
|
|
||
|
|
