Property Value

Type: System.Int64
An Int64 value that indicates the total number of IP packets received with an unknown protocol.

The protocol field in the IP header indicates the next-level protocol used in the data portion of the IP datagram. If the protocol is not recognized, the data cannot be passed to the correct application.

The following code example displays statistics for received IP packets with errors.


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);
}
