[<System.Runtime.Versioning.UnsupportedOSPlatform("android")>]
member this.PacketFragmentFailures : int64

Public MustOverride ReadOnly Property PacketFragmentFailures As Long

Valor da propriedade

Int64

Um Int64 valor que especifica o número total de pacotes que exigiam fragmentação, mas que tinham o bit "Não Fragmentar" definido.

Atributos

Exemplos

O exemplo de código a seguir exibe estatísticas de remontagem para pacotes IP.

void ShowFragmentationStatistics()
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   IPGlobalStatistics ^ ipstat = properties->GetIPv4GlobalStatistics();
   Console::WriteLine( "  Reassembly Data:" );
   Console::WriteLine( "      Reassembly Timeout .................. : {0}", 
      ipstat->PacketReassemblyTimeout );
   Console::WriteLine( "      Reassemblies Required ............... : {0}", 
      ipstat->PacketReassembliesRequired );
   Console::WriteLine( "      Packets Reassembled ................. : {0}", 
      ipstat->PacketsReassembled );
   Console::WriteLine( "      Packets Fragmented .................. : {0}", 
      ipstat->PacketsFragmented );
   Console::WriteLine( "      Fragment Failures ................... : {0}", 
      ipstat->PacketFragmentFailures );
}

}

Comentários

Os pacotes que excedem o tamanho máximo do transporte ip são divididos em fragmentos e remontados no destino. O valor retornado por essa propriedade indica o número de pacotes que precisavam ser fragmentados para o transporte ip, mas não pôde ser porque o cabeçalho do pacote especificou que o pacote não era fragmentado.
