For each event that can be fired by the core Network Configuration Manager server, there is a corresponding transform definition inside an XML file that takes the native event, and transforms it into an SNMP trap.
These traps conform to the MIB that is defined in the core Network Configuration Manager product.
This file is located in the following directory:
$VOYENCE_HOME/ncmcore/webapps/ncm-webapp/WEB-INF/classes/SNMP_Transform.xml
The SNMP transport takes the transformed event and sends it, via the SNMP protocol, to the configured vendor installation.
