     3This page documents various odds-and-ends regarding !OpenFlow and related platforms, tools, and whatnot.

     5 * Using xterm with mininet hosts. You can background then by doing:
     6   {{{
     7   mininet> h1 xterm &
     8   }}}
     9   this allows you to spawn a terminal for a switch, from which you can, say, sniff packets using wireshark.

     11 * A good way to track packets and transactions between datapath and controller is via buffer Id for switch-initiated conversations, and by XID for controller-initiated transactions. A caveat is that the buffer ID is only applicable to a subset of messages e.g. !PacketIns and !PacketOuts. A -1 buffer ID indicates a controller-generated packet (e.g. by a flow pushing tool or via a REST API for static flows).
