Pica8 PicOS software leverages Open vSwitch, a production quality, multi-layer virtual switch licensed under the open source Apache 2.0 license. OVS runs as a process within PicOS. The OpenFlow protocol is driven by the Open Networking Foundation (ONF), a leader in software-defined networking (SDN). The OpenFlow protocol governs three essential components of SDN, including an OpenFlow physical switch, an OpenFlow virtual switch to manage virtual machines, and an OpenFlow controller to organize all network pieces.


This document presents OVS commands arranged in three major sections:

  • ovs−appctl: Utility for querying and controlling ovs-vswitchd (Open vSwitch daemon) 
  • ovs-ofctl: OpenFlow switch management utility
  • ovs-vsctl: Utility for configuring and controlling ovs-vswitchd (Open vSwitch daemon)
