Configuring Jumbo Frames

The RtxTcpIp stack can support frame sizes greater than the historical standard of 1500 bytes.

To configure the stack and your NIC cards to use jumbo frames:

  1. Set the MTU value for the individual NIC card so that it is equal to an MTU supported by the card (presumably larger than 1500 bytes).
  2. Configure the StackMTU so that it is equal to or greater than the largest MTU value you have specified for any of your individual NIC cards.

NOTE:  Maximum frame size is hardware-specific and you should consult your NIC card's hardware documentation for acceptable values.
