Mininet commands
Mininet is a great tool for virtualizing the OpenFlow lab. As discussed before, Mininet is a wrapper over multiple tools, such as OVS, and Linux containers. It allows you to create different configurations and labs using virtual switches.
Mininet has lots of commands and CLI arguments; we will cover only the relevant ones here:
- Arguments
--Topo
Topo is used to tell Mininet what kind of topology to build. There are predefined topologies in Mininet, such as linear, tree, and minimal; also, you can create and define your own topology using a script.

--mac
This argument generates the host's MAC addresses based on the host ID; it is very useful for debugging and testing.
-v debug

--arp
