<p>Change the value of the MANAGER parameter to the IP address or hostname of the system where you want SNMP trap messages sent. 
</p>
<p>You can also make other changes to the <code>CONFIG.master</code> file as documented within the file.
</p>
</li>
<li>
<p>On AIX systems only, add the following line to the <code>&#047;etc&#047;snmpd.conf</code> file, where <em><code>ip&#095;address</code></em> is the IP address of the Oracle subagent:
</p>
<pre>smux 0.0 " " <em>ip&#095;address</em>

<p>To configure the encapsulator, perform the following steps:

<ol type="1" start="1">
<li>
<p>Add the following line to the <code>snmpd.conf</code> file, where <em><code>hostname&#095;or&#095;IP&#095;address</code></em> represents the local system IP address or host name:

<p>On AIX systems only, modify the port numbers specified for the NEW&#095;SNMPD&#095;PORT and NEW&#095;TRAPD&#095;PORT variables in the <code>start&#095;peer</code> script, if necessary. 
</p>
<p>The port number specified for the NEW&#095;SNMPD&#095;PORT variable must be different to the port number specified for the NEW&#095;TRAPD&#095;PORT variable.

<li>
<p>On all platforms except AIX, complete the following steps:
</p>
<ol type="a">
<li>
<p>If necessary, modify the port number specified in the <code>CONFIG.encap</code> file. The default port number is 1161.
</p>
</li>
<li>
<p>If you modified the port number in step a, change the value specified for the NEW&#095;SNMPD&#095;PORT variable in the <code>start&#095;peer</code> script to this port number.
</p>
</li>
<li>
<p>If necessary, modify the value specified for the NEW&#095;TRAPD&#095;PORT variable.

<p>This variable specifies the PEER encapsulator port to which the <code>snmpd</code> agent sends traps. This port number must be different to the port number specified for the NEW&#095;SNMPD&#095;PORT variable.

<p>To start the SNMP components, perform the following steps:
</p>
<ol type="1" start="1">
<li>
<p>Enter the following commands to verify that the SNMP components (<code>master&#095;peer</code>, <code>encap&#095;peer</code>, and <code>snmpd</code>) are <em>not</em> running:

<pre>&#036; ps -aef &#124; grep peer
&#036; ps -aef &#124; grep snmp

<p>&thinsp;If any of the components are running, log in as the <code>root</code> user and use the <code>kill</code> command to terminate the processes before proceeding.
</p>
</li>
<li>
<p>On AIX systems only, enter the following command as the <code>root</code> user to start the native AIX SNMP agent: 
</p>
<pre>&#035; startsrc -s snmpd "-f &#047;tmp&#047;snmpd.log"

</pre>
<p>This command starts the SNMP daemon and logs information in the <code>&#047;tmp&#047;snmpd.log</code> file.
</p>
</li>
<li>
<p>On all platforms except AIX, complete the following steps:
</p>
<ol type="a">
<li>
<p>As the <code>root</code> user, run the <code>start&#095;peer</code> script to start the PEER master agent, PEER encapsulator, and native UNIX SNMP agent:
