Remarks

Three classes are included that specialize the Trap2Message class to standard NOTIFICATION-OBJECTs that are defined in RFC 1907:

1. Dart.Snmp.Trap2.coldStart

2. Dart.Snmp.Trap2.warmStart

3. Dart.Snmp.Trap2.authenticationFailure

This class replaces the NotificationMessage class in version 4.5 and prior.

Serializable using BinaryFormatter and XmlSerializer.

Example

The following example demonstrates how to send traps with the agent.

private void TrapSender_Load(object sender, EventArgs e)
{
    //Set sysObjectId to your enterprise number (for Trap1).
    agent1.Variables.Add(agent1.Mib.GetByNodeName(NodeName.sysObjectID).GetIid(), agent1.Mib.CreateVariable(NodeName.sysObjectID, "1.3.6.1.4.1.52222"));
}

private void buttonSendTrap1_Click(object sender, EventArgs e)
{
    //Send an SNMPv1 Trap
    agent1.Send(new Dart.Snmp.Trap1.warmStart(agent1.Variables[agent1.Mib.GetByNodeName(NodeName.sysObjectID).GetIid()].Value.ToString(), agent1.SysUpTime), myManagerAddress);
}

private void buttonSendTrap2_Click(object sender, EventArgs e)
{
    //Send an SNMPv2 Trap (for SNMPv3, configure warmStart.Security.User)
    agent1.Send(new Dart.Snmp.Trap2.warmStart(agent1.SysUpTime), myManagerAddress);
}

Visual Basic

Private Sub TrapSender_Load(ByVal sender As Object, ByVal e As EventArgs)
    'Set sysObjectId to your enterprise number (for Trap1).
    agent1.Variables.Add(agent1.Mib.GetByNodeName(NodeName.sysObjectID).GetIid(), agent1.Mib.CreateVariable(NodeName.sysObjectID, "1.3.6.1.4.1.52222"))
End Sub

Private Sub buttonSendTrap1_Click(ByVal sender As Object, ByVal e As EventArgs)
    'Send an SNMPv1 Trap
    agent1.Send(New Dart.Snmp.Trap1.warmStart(agent1.Variables(agent1.Mib.GetByNodeName(NodeName.sysObjectID).GetIid()).Value.ToString(), agent1.SysUpTime), myManagerAddress)
End Sub

Private Sub buttonSendTrap2_Click(ByVal sender As Object, ByVal e As EventArgs)
    'Send an SNMPv2 Trap (for SNMPv3, configure warmStart.Security.User)
    agent1.Send(New Dart.Snmp.Trap2.warmStart(agent1.SysUpTime), myManagerAddress)
End Sub
