Examples with ScopedPDU org.snmp4j.ScopedPDU used on opensource projects

Example 1 with ScopedPDU

use of org.snmp4j.ScopedPDU in project opennms by OpenNMS.

the class Snmp4JAgentConfig method createPdu.

/**
     * Creates an SNMP4J PDU based on the SNMP4J version constants.
     * A v3 request requires a ScopedPDU.
     *
