[pox-dev] openflow, pox tplink

This log message...

WARNING:forwarding.l2_learning:Same port for packet from 38:60:77:3f:89:86 -> 00:22:fb:98:a9:f2 on 00-00-00-00-00-01.1.  Drop.

.. indicates that POX is learning that a source and its destination are both out the same switch port.  A common case where this occurs is with wireless, because all the wireless devices appear to be the same port.  Additionally, most wireless adapters have an "internal bridge" (which can often be disabled) which forwards packets between wireless devices before they ever reach the actual network stack (and OpenFlow).

So: Are you trying to ping between two wireless clients of the tplink?  Or do you have two cables plugged into it?  In either case, please describe your topology/setup including ports and ethernet address.

> Also, add openflow.keepalive onto your commandline. There's a bug in the reference switch which causes it to disconnect a lot without this.
> 
> sorry i cant see, keep alive both on ofprotocol and or pox, can u guide further?

Like...
