![]() ![]() The user may configure each switch by right-clicking on it an choosing Properties from the menu. The tool operates the same way as the Hosts tool above. These switches are expected to be connected to a controller. The Switch tool creates OpenFlow-enabled switches on the canvas. The user may configure each host by right-clicking on it and choosing Properties from the menu. As long as the tool remains selected, you can keep adding hosts by clicking anywhere on the canvas. Click on the tool, then click anywhere on the canvas you wish to place a node. The Host tool creates nodes on the canvas that will perform the function of host computers. To select an existing node or link, just hover the mouse pointer over it - this works regardless of the tool that is currently active - and then either right-click to reveal a configuration menu for the selected element or press the Delete key to remove the selected element. Interestingly the Select tool is not needed to select a node or link on the canvas. The Select tool is used to move nodes around on the canvas. MiniEdit has a simple user interface that presents a canvas with a row of tool icons on the left side of the window, and a menu bar along the top of the window. ![]() Mininet needs to run with root privileges so we started MiniEdit using the sudo command. To run MiniEdit, execute the command: $ sudo ~/mininet/examples/miniedit.py The MiniEdit script is located in Mininet’s examples folder. If you need to learn how to do this, please read my post describing how to set up Mininet. If you need some basic information about Mininet, please read my Mininet overview.īefore starting this tutorial, you should have already started the Mininet VM and connected to it via SSH with X forwarding enabled. You should already be familiar with Mininet before trying to use MiniEdit. To show how to use MiniEdit to create and run network simulations, we will work through a tutorial that demonstrates how to use MiniEdit to build a network, configure network elements, save the topology, and run the simulation. MiniEdit is an experimental tool created to demonstrate how Mininet can be extended. The Mininet network simulator includes MiniEdit, a simple GUI editor for Mininet. ![]()
