Example 6 with UsmUser

use of org.snmp4j.security.UsmUser in project opennms by OpenNMS.

the class Snmp4jTrapReceiverIT method testTrapReceiverWithoutOpenNMS.

/*
     * IMPORTANT:
     *
     * The sentence <code>snmp.getUSM().addUser(...)</code>, is the only requirement
     * in order to properly process SNMPv3 traps.
     * 
     * This is related with the credentials that should be created for Trapd in order
     * to properly authenticate and/or decode SNMPv3 traps in OpenNMS.
     * 
     * This is a user that should be configured (or should be used) by the external
     * devices to send SNMPv3 Traps to OpenNMS.
     * 
     * The SNMPv3 users should be configured in trapd-configuration.xml
