In the lab, I quite often find my self installing Open vSwitch instances, configuring network parameters for certain functionality and probing network interfaces to check connectivity, again and again. You know, the daily routines in an OpenFlow research laboratory. To ease the workflow, I put together a small toolbelt.

$ of-toolbelt.sh
Usage: of-toolbelt.sh <ACTION>
Actions: ofctl
         vsctl
         vswitchd
         insmod
         db_create
         db_start
         get_controller
         set_controller
         del_controller
         get_dpid
         set_dpid
         get_stp
         set_stp
         dl_ovs
         install_ovs
         ethtool_help
         arping_help
$ of-toolbelt.sh dl_ovs
$ of-toolbelt.sh install_ovs openvswitch-1.4.1.tar.gz
