LANforge-ICE Cookbook

The LANforge-ICE Cookbook provides a set of high-level examples of how to setup useful test scenarios in LANforge-ICE for WAN emulation. Each example intends to give the reader a brief introduction to the test scenario and a set of step-by-step instructions on how to use the LANforge-GUI to configure the test.

All of the following examples will work on Linux systems running the LANforge software with the LANforge kernel and a sufficient license. If you are running another Linux kernel, you will not be able to exactly duplicate some of the examples, but there are usually work-arounds available to assist you. Please contact us at if you have any questions.

If you are using the Windows version of LANforge, you will have to modify ports using the Windows utilities and you will not be able to duplicate the Routed Mode ICE examples. Everything else should work approximately the same, but the performance is limited to 10Mbps speeds.
