Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Gets the maximum transmission unit (MTU) for this network interface.
public:
abstract property int Mtu { int get(); };
public abstract int Mtu { get; }
member this.Mtu : int
Public MustOverride ReadOnly Property Mtu As Integer
Property Value
An Int64 value that specifies the MTU.
Examples
The following code example gets an IPv4InterfaceProperties object and displays its data.
void DisplayIPv4NetworkInterfaces()
{
array<NetworkInterface^>^nics = NetworkInterface::GetAllNetworkInterfaces();
IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
Console::WriteLine( "IPv4 interface information for {0}.{1}", properties->HostName, properties->DomainName );

while ( myEnum23->MoveNext() )
{
NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum23->Current);
// Only display informatin for interfaces that support IPv4.
if ( adapter->Supports( NetworkInterfaceComponent::IPv4 ) == false )
{
continue;
}
Console::WriteLine();
Console::WriteLine( adapter->Description );
// Underline the description.
Console::WriteLine( String::Empty->PadLeft( adapter->Description->Length, '=' ) );
IPInterfaceProperties ^ adapterProperties = adapter->GetIPProperties();
// Try to get the IPv4 interface properties.
IPv4InterfaceProperties ^ p = adapterProperties->GetIPv4Properties();
if ( !p )
{
Console::WriteLine( "No IPv4 information is available for this interface." );
continue;
}
// Display the IPv4 specific data.

Remarks
The MTU of a network interface is the largest packet that can be transmitted. It is measured in octets (8-bit bytes).
