>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, On Thu, Feb 7, 2013 at 1:50 AM, Murphy McCauley <[email protected]>wrote: > 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. > > Was this from doing a ping?
