>Was this from doing a ping? What are those two MAC addresses?

yes ping, two machines connected to switch ports.

>Are you trying to ping between wireless devices?

yes my laptop is on wireless to another AP that is connected to an ethernet
port to this switch and the other IP is a machine connected to it's other
port.

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?



thank u,
