SetMTU method of the Win32_NetworkAdapterConfiguration class
The SetMTU WMI class static method is used to set the default Maximum Transmission Unit (MTU) for a network interface.
This topic uses Managed Object Format (MOF) syntax. For more information about using this method, see Calling a Method.
Syntax
uint32 SetMTU(
[in] uint32 MTU
);
Parameters
-
MTU [in]
-
Default Maximum Transmission Unit (MTU) for a network interface. The range of this value spans the minimum packet size (68) to the MTU supported by the underlying network.
Return value
Returns a value of 0 (zero) for a successful completion when no reboot is required, 1 (one) for a successful completion when a reboot is required, and a different number if there is an error. For more information on error codes, see WMI Error Constants or WbemErrorEnum. For general HRESULT values, see System Error Codes.

Remarks
The MTU is the maximum packet size (in bytes) that a transport will transmit over the underlying network. The size includes the transport header.
Note that an IP datagram can span multiple packets. Values larger than the default for the underlying network result in the transport using the network default MTU. Values smaller than 68 result in the transport using an MTU of 68.
