[pox-dev] forwarding.l2_learning

[Murphy McCauley]

There have been other people having problems with NetFPGAs that have been magically fixed by rebuilding the NetFPGA software -- nothing to do with POX.

In this case, it seems like packets just aren't getting to the destination or back from the destination.  You don't specify which ports you see the traffic on, or what control traffic you see.

I'd start by trying an experiment with one switch.  Actually, I guess I'd first try rebuilding the NetFPGA code. :)
