Property Value

Type: System::Int64

An Int64 value that specifies the total number of Destination Unreachable messages received.

A Destination Unreachable message can be sent to the computer that is the source of a packet for any of the following reasons:

  • The computer cannot find a route to the destination address.

  • Communication with the destination address is administratively prohibited. For example, a firewall prevents delivery of packets to the destination.

  • The destination address is unreachable.

  • The destination port is unreachable. For example, there is no listener available for the packet's protocol.

The following example displays the value of this property.

void ShowIcmpV6UnreachableData()
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   IcmpV6Statistics ^ statistics = properties->GetIcmpV6Statistics();
   Console::WriteLine( "  Destination Unreachables ............ Sent: {0,-10}   Received: {1,-10}", 
      statistics->DestinationUnreachableMessagesSent, 
      statistics->DestinationUnreachableMessagesReceived );
}
