  public byte[] EngineIdB { get; }
  public int EngineBoots { get; }
  public int EngineTime { get; }
  public string User { get; }

  public int SourcePort { get; }
}

Public Event OnDiscoveryResponse As OnDiscoveryResponseHandler

Public Delegate Sub OnDiscoveryResponseHandler(sender As Object, e As SnmpmgrDiscoveryResponseEventArgs)

Public Class SnmpmgrDiscoveryResponseEventArgs Inherits EventArgs
  Public ReadOnly Property EngineId As String
  Public ReadOnly Property EngineIdB As Byte()
  Public ReadOnly Property EngineBoots As Integer
  Public ReadOnly Property EngineTime As Integer
  Public ReadOnly Property User As String
  Public ReadOnly Property SecurityLevel As Integer
  Public ReadOnly Property SourceAddress As String
  Public ReadOnly Property SourcePort As Integer
End Class

Remarks

EngineId, EngineBoots, EngineTime, and User are the values received from SourceAddress and SourcePort.

The SecurityLevel parameter shows whether the request has been authenticated. If SecurityLevel is 0, the request has NOT been authenticated (i.e. the packet signature has not been verified). For an authenticated request, SecurityLevel is at least 1.
