Class MockSnmpAgent

java.lang.Object

org.snmp4j.agent.BaseAgent

org.opennms.mock.snmp.MockSnmpAgent

All Implemented Interfaces:

Runnable

public class MockSnmpAgent
extends org.snmp4j.agent.BaseAgent
implements Runnable

The MockSnmpAgent class extends the SNMP4J BaseAgent class to provide a mock SNMP agent for SNMP-based OpenNMS tests. Large chunks of code were lifted from the org.snmp4j.agent.test.TestAgent class.

Constructor and Description
MockSnmpAgent(File confFile, URL moFile)

Constructor Detail

MockSnmpAgent

public MockSnmpAgent(File confFile,
             URL moFile)

MockSnmpAgent

public MockSnmpAgent(File confFile,
             URL moFile,
             String bindAddress)

Creates the mock agent with files to read and store the boot counter, to read and store the agent configuration, and to read the mocked managed objects (MOs), plus a string describing the address and port to bind to.

Parameters:

moFile - a MIB dump file describing the managed objects to be mocked. The current implementation expects a Java properties file, which can conveniently be generated using the Net-SNMP utility snmpwalk with the -One option set.
