Ejemplos

En el ejemplo de código siguiente se muestran estadísticas de paquetes IP recibidos con errores.

void ShowInboundIPErrors()
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   IPGlobalStatistics ^ ipstat = properties->GetIPv4GlobalStatistics();
   Console::WriteLine( "  Inbound Packet Errors:" );
   Console::WriteLine( "      Header Errors ....................... : {0}", 
      ipstat->ReceivedPacketsWithHeadersErrors );
   Console::WriteLine( "      Address Errors ...................... : {0}", 
      ipstat->ReceivedPacketsWithAddressErrors );
   Console::WriteLine( "      Unknown Protocol Errors ............. : {0}", 
      ipstat->ReceivedPacketsWithUnknownProtocol );
}

public static void ShowInboundIPErrors()
{
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    IPGlobalStatistics ipstat = properties.GetIPv4GlobalStatistics();
    Console.WriteLine("  Inbound Packet Errors:");
    Console.WriteLine("      Header Errors ....................... : {0}",
        ipstat.ReceivedPacketsWithHeadersErrors);
    Console.WriteLine("      Address Errors ...................... : {0}",
        ipstat.ReceivedPacketsWithAddressErrors);
    Console.WriteLine("      Unknown Protocol Errors ............. : {0}",
        ipstat.ReceivedPacketsWithUnknownProtocol);
}

Public Shared Sub ShowInboundIPErrors() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim ipstat As IPGlobalStatistics = properties.GetIPv4GlobalStatistics()
    Console.WriteLine("  Inbound Packet Errors:")
    Console.WriteLine("      Header Errors ....................... : {0}", ipstat.ReceivedPacketsWithHeadersErrors)
    Console.WriteLine("      Address Errors ...................... : {0}", ipstat.ReceivedPacketsWithAddressErrors)
    Console.WriteLine("      Unknown Protocol Errors ............. : {0}", ipstat.ReceivedPacketsWithUnknownProtocol)

End Sub

Comentarios

El campo de protocolo del encabezado IP indica el protocolo de siguiente nivel que se usa en la parte de datos del datagrama IP. Si no se reconoce el protocolo, los datos no se pueden pasar a la aplicación correcta.
